Choosing the Right Maintenance to Cut Car Costs and Faults

When you change your car’s rims, you may be surprised by a rise in fuel consumption without any warning. The problem is not always the engine, as some people think… so what exactly do the rims do?

Do larger rims increase fuel consumption?

• The larger the rim diameter, the greater the rotational resistance, forcing the engine to work harder.
• Large rims are often fitted with wider tires, which increases friction with the road.
• A larger diameter changes the effective gear ratios, making acceleration heavier and increasing consumption.
• Tests indicate that larger rims may raise consumption by 4–10% depending on weight.

 

How does rim weight affect fuel consumption?

Rim weight affects fuel consumption as follows:

• Heavy rims increase what is known as “unsprung weight”, which has the greatest impact on performance.
• Every extra kilogram in the rim multiplies the effort needed to rotate it compared with weight inside the car.
• The engine needs more energy to start moving and maintain speed, which raises fuel consumption.
• Lightweight rims (such as aluminum) reduce the load on the engine and improve fuel economy.

 

Does rim design affect fuel consumption?

• A non-aerodynamic design obstructs airflow around the wheel, increasing air resistance.
• Economy cars use closed or semi-closed rims to improve aerodynamics.
• Sporty rims with large openings may look better but are less fuel-efficient.
• Manufacturers design special rims for electric vehicles to reduce aerodynamic drag.

 

Does the width of the tire fitted on the rim affect fuel consumption?

The width of the tire fitted on the rim affects fuel consumption as follows:

• A wider tire increases the contact area with the road, raising frictional resistance.
• This extra friction makes the engine work harder, and therefore increases consumption.
• Changing the rim often requires changing the tire width, which multiplies the effect on consumption.
• Narrow tires are more fuel-efficient than wide ones.

 

Do large rims affect the car’s acceleration?

• A larger diameter and greater weight make the car slower to pull away from a standstill.
• Weaker acceleration means the engine stays at higher RPM for longer, which increases consumption.
• This effect is clearly noticeable on city roads, where stopping and starting are frequent.
• Small cars are affected more than large ones when rims are changed.

 

Does changing rims affect the speedometer reading?

Yes, rims can affect the speedometer reading as follows:

• Larger rims change the wheel’s rolling circumference, which affects speedometer accuracy.
• The speed reading may become higher or lower than the actual speed, depending on the new tire size.
• This difference may lead to inaccurate driving and unaccounted-for extra consumption.
• Tires and rims should be matched to the original specifications to avoid this problem.

 

Do unsuitable rims put extra strain on the engine?

• The engine is designed to work with a specific wheel weight and size; any major change forces extra effort on the engine, especially when climbing or carrying loads.
• This effort leads to higher fuel consumption and a rise in the car engine’s temperature, and in some cases noises or vibrations may appear due to incompatibility.

 

Do large rims affect the suspension system?

Yes, large rims may affect the suspension system, as follows:

• The extra weight puts pressure on the shock absorbers and control arms, shortening their lifespan.
• The suspension system becomes less able to absorb shocks, which increases resistance to movement.
• This causes part of the kinetic energy to be lost and converted into friction, and therefore increases consumption.
• Lightweight rims keep the suspension smooth and reduce fuel consumption.

 

What increase in fuel consumption should you expect when changing rims?

• Larger rims may increase consumption by 4–10% depending on weight and design.
• Wider tires may add a further increase of 2–5%.
• Heavy rims may raise consumption more than large rims themselves.
• Small and mid-size cars are affected more than large cars.

 

How do you choose the right rims without increasing fuel consumption?

You can choose the right rims without increasing fuel consumption by:

1. Choosing rims with the same original diameter whenever possible. 
2. Avoiding very heavy rims, and preferring aluminum or lightweight alloys. 
3. Keeping the tire width within standard specifications. 
4. Choosing an aerodynamic design that reduces air resistance. 
5. Making sure the rim is compatible with the suspension system and the engine.

A car’s behavior on the road changes with its drivetrain, which can leave the driver facing unexpected situations in terms of stability and traction. So how do you choose the system that prevents these problems before they happen?

What are drivetrain systems in cars?

• The drivetrain refers to the way engine power is transferred to the wheels, which determines how the car moves and how stable it is on the road. Systems vary between front-wheel drive, rear-wheel drive and four-wheel drive, and each offers a different driving experience in terms of control, acceleration and grip.
• Manufacturers choose the appropriate drivetrain according to the car’s segment and intended use: some systems suit the city, others suit highways, and others suit rough terrain.
• Understanding these systems helps the driver anticipate how the car will behave in different conditions, which increases safety and makes it easier to choose the right car for their needs.

 

How does front-wheel drive work in cars?

Front-wheel drive works as follows:

1. In a front-wheel drive system, power is transferred from the engine to the front wheels, making them responsible for both traction and steering at the same time. This design reduces the number of mechanical components and improves fuel efficiency. 
2. Front-wheel drive provides good stability on wet or slippery roads, because the weight of the engine over the front wheels improves grip. 
3. However, combining traction and steering limits sporty performance, especially under hard acceleration or sharp cornering, when the front wheels may lose some of their grip.

 

What are the advantages of front-wheel drive?

Front-wheel drive offers several advantages, the most important of which are:

• It delivers low fuel consumption thanks to lighter weight and fewer components.
• It provides more interior space because the car does not need a driveshaft running to the rear.
• It offers good stability in everyday conditions, especially in cities and on paved roads.
• It suits drivers looking for a practical, economical car for daily use.

 

What are the disadvantages of front-wheel drive?

The main disadvantages of front-wheel drive include:

• It offers weaker sporty performance, especially at high speeds or in sharp corners.
• Front-wheel slip can occur under heavy throttle, because the front wheels handle both traction and steering.
• Unbalanced weight distribution can affect control in corners.
• It is not suitable for rough roads or aggressive driving.

 

How does rear-wheel drive work in cars?

Rear-wheel drive works as follows:

1. In a rear-wheel drive system, power is sent to the rear wheels while the front wheels handle steering only, giving the car a better balance between traction and control. 
2. This separation of traction and steering makes the car better able to handle strong acceleration and gives it excellent stability at high speeds. 
3. This system relies on a driveshaft and a rear differential, which adds a little weight but gives the car greater maneuverability.

 

What are the advantages of rear-wheel drive?

The most important advantages of rear-wheel drive include:

• It delivers distinctive sporty performance and excellent stability at high speeds.
• It allows ideal weight distribution between the front and rear, improving control in corners.
• It provides better acceleration, especially in sports and luxury cars.
• It suits drivers who want an enjoyable drive or need extra towing power.

 

What are the disadvantages of rear-wheel drive?

The disadvantages of rear-wheel drive include:

• It has weaker grip on wet or snowy roads, because the rear wheels do not carry the engine’s weight.
• Fuel consumption is relatively higher due to the larger number of components.
• Maintenance costs are higher because of the driveshaft and rear differential.
• It may be less suitable for daily driving in congested cities.

 

How does four-wheel drive work?

Four-wheel drive works as follows:

1. In a four-wheel drive system, power is sent to all four wheels, either permanently or when needed, giving the car tremendous grip in difficult conditions. 
2. This system relies on additional differentials and electronic systems that distribute power between the wheels as needed, helping the car overcome obstacles and rough roads. 
3. Four-wheel drive is used in SUVs and trucks, and it is the best choice for sandy, muddy and snowy roads.

 

What are the types of four-wheel drive?

The main types of four-wheel drive are:

1. Permanent four-wheel drive: it works all the time and continuously distributes power between the front and rear, providing excellent stability on all types of roads. 
2. Part-time four-wheel drive: it works when the driver engages it, and is usually used on rough roads to save fuel. 
3. Intelligent AWD: an advanced electronic system that automatically distributes power according to road conditions, combining the efficiency of front-wheel drive with the capability of four-wheel drive. 
4. AWD is well suited to daily use because it balances performance and economy.

 

How do you choose the right drivetrain for your needs?

Choosing a drivetrain to match your needs depends on the following:

1. If you drive in the city and want an economical car: front-wheel drive is the most suitable. 
2. If you want an enjoyable drive and stability at high speeds: rear-wheel drive offers the best experience. 
3. If you travel on difficult roads or in mountainous areas: four-wheel drive is the strongest and safest choice. 
4. The decision depends on your budget, the type of roads and your daily driving style, so it is important to understand the differences between the three systems before deciding. 
5. Fuel consumption should also be considered, because four-wheel drive consumes more, while front-wheel drive is the most economical.

 

What is the difference between AWD and 4WD?

The most important differences between AWD and 4WD are:

1. AWD automatically distributes power between the wheels as needed, giving the car extra stability on normal roads and in moderate conditions without driver intervention. The system works through sensors that detect slip and instantly redistribute power. 
2. 4WD, on the other hand, is a stronger mechanical system, usually used on rough roads, and allows the driver to manually engage full four-wheel drive. This system provides high traction in sand, mud and mountains. 
3. The main difference between them is that AWD is suitable for daily driving, while 4WD is designed for difficult roads that require strong traction.

 

How does climate affect the choice of drivetrain?

Climate affects the choice of drivetrain as follows:

• Climate plays a key role in determining the most suitable drivetrain, as each system handles weather conditions differently. In areas that see rain or snow, AWD or four-wheel drive provides greater grip on slippery roads.
• In dry or hot areas, front-wheel or rear-wheel drive is sufficient, especially if the roads are paved and do not require extra traction.
• Understanding how climate affects the choice of drivetrain helps improve safety, reduce fuel consumption and ensure consistent performance in different conditions.

 

What is the best drivetrain for mountain roads?

The best drivetrain for mountain roads:

• Mountain roads demand high grip and strong traction, so four-wheel drive is considered the strongest option for these conditions. This system distributes power to all wheels, helping the car climb steadily and handle steep slopes.
• Some modern AWD systems also perform excellently on mountain roads, especially in mid-size crossover cars.
• Choosing the right system depends on the severity of the terrain and the type of car, but four-wheel drive remains the most reliable in mountains and rugged areas.

 

How does fuel consumption differ between front-wheel, rear-wheel and four-wheel drive?

• Front-wheel drive is the most fuel-efficient, because it uses fewer components and weighs less, reducing the energy needed to move the car.
• Rear-wheel drive consumes slightly more fuel because of the driveshaft and rear differential, but it offers better sporty performance and greater stability at high speeds.
• Four-wheel drive has the highest fuel consumption, because it runs additional components and needs more energy to turn all the wheels, especially in permanent systems.
• The driver should therefore choose the right system based on how they use the car and the running costs they can afford.

 

Which is better: front-wheel, rear-wheel or four-wheel drive?

• Front-wheel drive offers the best fuel economy and good stability on everyday roads, making it suitable for cities and normal use.
• Rear-wheel drive offers higher sporty performance and excellent stability at high speeds, making it an ideal choice for those who enjoy driving.
• Four-wheel drive offers the best ability to handle difficult and rough roads, and provides strong grip in harsh conditions such as rain and snow.
• Choosing the best system depends on the driver’s usage, the climate, the type of road and the budget, so no single system suits everyone; each has its own strengths and weaknesses.

 

Watch for changes in how your car behaves when you press the accelerator, and for increased vibrations caused by a clogged air filter restricting airflow to the engine. Do you know the signs that reveal this problem?

 

What are the signs of a clogged air filter?

The most important signs of a clogged air filter include:

• Weak torque appears when the car loses its ability to accelerate smoothly and struggles to climb hills because less air is entering the engine.
• Increased fuel consumption occurs when the engine has to inject more fuel to compensate for the lack of air, leading to a noticeable rise in consumption.
• Engine vibration appears while idling or driving slowly, as the clogged filter disrupts the air-fuel mixture.
• A smell of unburned fuel indicates incomplete combustion inside the cylinders due to weak airflow.

 

How does a dirty air filter affect engine performance?

A dirty air filter affects engine performance through:

1. Lower combustion efficiency occurs when the engine does not get the air it needs, leading to weaker power and reduced overall performance. 
2. Slower engine response appears when you press the accelerator, as the engine is late in producing the required power due to weak airflow. 
3. Higher engine temperature results from non-ideal combustion, which puts extra stress on internal parts and increases the likelihood of overheating while driving. 
4. A louder engine occurs when airflow becomes irregular, making the engine sound louder than usual.
5. Reduced acceleration is clearly noticeable when trying to overtake or pull away quickly, due to the lack of air entering the engine. 

 

Does a damaged air filter cause abnormal noise?

• A whistling sound appears when you press the accelerator, as air tries to pass through a clogged filter.
• A rough engine sound occurs when airflow becomes irregular, making the engine louder and harsher than usual.
• Engine misfiring appears during slow driving because not enough air reaches the combustion process.

 

How does the air filter affect fuel consumption?

The air filter’s effect on fuel consumption:

1. Increased fuel delivery occurs when the electronic system tries to compensate for the lack of air, which can raise consumption by up to 20%. 
2. Lower engine efficiency appears when the engine works harder to produce the same power due to weak airflow. 
3. Poorer fuel economy shows when the car needs refueling more often than usual even though your driving style has not changed. 
4. Higher emissions result from incomplete fuel combustion due to the lack of air, which indirectly increases fuel consumption. 

 

Does the air filter affect the car’s emissions?

Yes, the air filter can affect the car’s emissions as follows:

1. Higher emissions result from incomplete fuel combustion due to the lack of air, increasing the amount of pollutants coming out of the exhaust. 
2. Failing an emissions test happens when pollutant levels rise due to a clogged filter, making the car non-compliant with environmental standards. 
3. Sensor malfunction occurs when a clogged filter leads to inaccurate readings from the oxygen sensor, which confuses the injection system and raises emissions. 
4. A stronger exhaust smell appears when combustion is incomplete, making the exhaust smell stronger than usual. 

 

What is the ideal air filter replacement interval?

• Replacing the filter every 15,000 to 20,000 km is suitable for most cars to ensure a flow of clean air to the engine.
• Replacing the filter more often in dusty areas becomes necessary, because the filter fills with dirt more quickly.
• The replacement interval varies by filter type, as sports or high-performance filters need more regular maintenance and cleaning than conventional filters.

 

How do you check the air filter yourself?

You can check the air filter as follows:

1. Opening the filter housing gives you easy access to it in the engine bay so you can check its condition directly. 
2. Checking the filter’s color helps you see how clogged it is, as a dark color or built-up dust indicates it needs replacing. 
3. A light test reveals the filter’s condition, as light not passing through it indicates that it is clogged. 
4. Smelling the filter helps detect oil or impurities that may affect airflow. 

 

Can the air filter be cleaned instead of replaced?

Yes, in some cases, including:

• Some filters can be cleaned, such as sports filters designed to be reused after washing or cleaning.
• Cleaning the filter with compressed air helps remove accumulated dust, provided it is dried well before refitting.
• Replacing a damaged filter becomes necessary when it is torn or worn, making cleaning it pointless.

 

How does the air filter affect engine life?

The air filter affects engine life as follows:

1. It protects the engine from dust by preventing dirt from entering, which would wear the cylinders and valves. 
2. It reduces strain on the engine, as proper airflow helps lighten the load on internal parts. 
3. It extends engine life, as a clean filter allows ideal combustion, which reduces breakdowns. 
4. It improves performance stability, as the engine receives a steady amount of air, making it run more smoothly. 

 

What are the best practices for maintaining the air filter?

The most important ways to maintain the air filter include:

1. Checking the filter regularly helps detect clogging early and maintain engine performance.  
2. Avoiding driving on dirt roads reduces dust build-up in the filter and extends its life. 
3. Using high-quality filters ensures better airflow to the engine and maintains combustion efficiency. 
4. Cleaning the filter housing regularly prevents dirt from building up around the filter and increases its effectiveness. 
5. Paying attention to the engine sound helps detect any change that may indicate a clogged filter before bigger problems occur. 

Does the air filter affect the car’s acceleration?

Yes, the air filter may affect the car’s acceleration as follows:

1. Weak acceleration appears when the engine does not get enough air, making the car slow to respond when you press the accelerator. 
2. Reduced ability to pull away quickly occurs due to lower airflow into the combustion chamber, which reduces the power available to the engine. 
3. Slow response when overtaking becomes noticeable when the filter is clogged, because the engine cannot produce the required power quickly. 

 

What is the difference between a genuine and an aftermarket air filter?

The most important differences between a genuine and an aftermarket air filter include:

• A genuine filter provides steady airflow to the engine because it is made to precise standards that match the car’s intake system.
• An aftermarket filter may reduce engine performance because it is often made of lower-quality materials, leading to faster clogging and poorer combustion.
• A genuine filter’s service life is much longer than an aftermarket one’s, making it a better choice for maintaining engine efficiency.
• An aftermarket filter may let fine impurities into the engine, increasing the likelihood of internal parts wearing over time.

 

Can the air filter cause problems with the air sensor?

Yes, the air filter can cause some problems with the air sensor, including:

1. A clogged filter disrupts airflow, causing the air sensor to give inaccurate readings to the electronic control unit. 
2. Dust build-up on the filter may let small particles into the air passage, affecting the sensor’s performance and making it send incorrect information to the engine. 
3. Weak airflow caused by a dirty filter makes the sensor think the amount of air is lower than it actually is, which leads to an imbalance in the air-fuel mixture.

Automatic transmissions suffer costly failures due to misuse and lack of maintenance, but looking after one is not as complicated as it seems. How do you protect your gearbox and ensure consistent performance for years?

Why is automatic transmission maintenance important?

• The automatic transmission is one of the most sensitive systems in the car, as it is responsible for smoothly managing the transfer of power from the engine to the wheels. Any neglect in its maintenance leads directly to problems in the car’s performance, such as delayed shifting or slipping during acceleration.
• Regular gearbox maintenance ensures the hydraulic system works efficiently, which reduces internal friction and prevents overheating, the leading cause of damage to gearbox components.
• Taking care of the gearbox helps reduce fuel consumption, because correct gear shifting prevents engine strain and keeps the engine operating within its optimal power range.
• Maintaining the gearbox extends the car’s overall lifespan, because any transmission damage often leads to a chain of failures in other systems, such as the cooling system or the engine.

 

How does transmission fluid affect gearbox performance?

Transmission fluid affects the gearbox as follows:

• Gearbox fluid is not just a lubricant; it is an essential element in transmitting hydraulic pressure inside the transmission, which allows the gears to shift smoothly.
• A low or contaminated fluid level causes the gearbox to overheat, leading to rapid wear of internal parts such as the clutches and metal plates.
• Fluid turning dark brown or giving off a burning smell indicates that it has lost its properties, meaning the gearbox is operating under abnormal stress that may cause permanent damage.
• Using fluid that does not match the manufacturer’s specifications disrupts shift timing and may cause noticeable vibrations while driving or gear slipping.

 

When should automatic transmission fluid be changed?

• Most modern cars need a gearbox fluid change between 40,000 and 60,000 km, but this figure may vary depending on the type of gearbox (conventional, CVT, or dual-clutch).
• Driving in harsh conditions, such as heavy traffic or mountain roads, makes the gearbox operate at higher temperatures, which calls for changing the fluid at shorter intervals to maintain performance.
• If the driver notices delayed shifting or slight vibrations when accelerating, this indicates the fluid should be checked immediately, even if the specified mileage has not been reached.
• Following the manufacturer’s maintenance schedule is the best way to avoid costly failures, because each transmission has different specifications for its fluid and service interval.

 

What bad habits speed up transmission damage?

Habits that quickly damage the transmission include the following:

• Shifting the gear selector from D to R before the car comes to a complete stop puts heavy stress on the internal gears and may break them over time.
• Frequent sudden acceleration quickly raises the fluid temperature, reducing its viscosity and increasing friction inside the gearbox.
• Towing heavy trailers without equipping the car for it strains the torque converter and makes the gearbox work beyond its design capacity, leading to premature damage.
• Ignoring abnormal noises such as whining or clunking during shifting makes the problem worse, as these noises are often a sign that internal damage has begun.

 

How does a proper driving style help protect the gearbox?

Driving style helps protect the gearbox as follows:

1. Driving progressively without sudden pressure on the accelerator prevents heat build-up inside the gearbox, preserving the fluid and extending the life of internal components. 
2. Coming to a complete stop before changing gear selector positions protects the gears from sudden shocks that cause rapid wear. 
3. Avoiding aggressive driving reduces stress on the hydraulic system and makes shifting smoother and more stable. 
4. Using the appropriate drive modes, such as Sport or Snow, according to conditions helps the gearbox operate within optimal settings, reducing strain on the system.

 

What role does the cooling system play in protecting the transmission?

The role of the cooling system in protecting the transmission is as follows:

• The transmission relies on a dedicated cooler, or a cooler shared with the radiator, to keep the fluid temperature within a safe range, because overheating is the gearbox’s number one enemy.
• A clogged or damaged cooler causes the fluid temperature to rise quickly, burning the fluid and stripping it of its properties, which in turn damages the internal clutches.
• Checking the cooling hoses and making sure there are no leaks or blockages helps maintain proper fluid flow within the system.
• For vehicles used for towing or off-road driving, installing an additional transmission cooler is recommended to reduce heat under heavy loads.

 

How can you detect early transmission faults?

You can detect early transmission faults in several ways, the most important of which are:

• Delayed shifting between gears or a feeling of slipping during acceleration are among the most prominent signs of a problem in the hydraulic system or internal clutches.
• Slight vibrations at a steady speed may indicate a problem with the torque converter or one of the gearbox sensors.
• Oil spots under the car indicate a leak from the transmission pan or one of the hoses, and this leak may cause the fluid level to drop dangerously.
• Whining or clunking noises during shifting require immediate inspection, as these noises are often the result of abnormal friction inside the gearbox.

 

What are practical tips for maintaining an automatic transmission?

The most important tips for maintaining an automatic transmission include the following:

1. Check the gearbox fluid level once a month, especially in hot weather, because high temperatures speed up fluid consumption. 
2. Clean and inspect the transmission cooler regularly to ensure effective cooling that prevents overheating inside the transmission. 
3. Use only the gearbox fluid recommended by the manufacturer, because each type of gearbox requires a specific viscosity and chemical composition. 
4. Have a comprehensive gearbox inspection every 20,000 km to confirm the condition of the gears and hydraulic components before any major damage occurs. 
5. Avoid overloading the car or driving in harsh conditions without proper preparation, as this puts heavy stress on the gearbox.

 

Does electronic programming affect transmission lifespan?

Yes, electronic programming can affect transmission lifespan as follows:

• Modern gearboxes rely on a Transmission Control Unit (TCU) to precisely set shift timing, and any programming fault leads to irregular shifting or delayed response.
• Software updates from the dealership often improve gearbox performance and reduce fuel consumption, as they adjust shift points according to the latest standards.
• Random programming or unofficial modifications may put excessive stress on the internal clutches, leading to rapid gearbox damage.
• Checking the gearbox sensors regularly helps maintain programming accuracy and prevent electronic errors.

 

What is the best way to ensure a long transmission life?

1. Sticking to regular maintenance and changing the fluid on time is the most important factor in preserving the gearbox. 
2. Adopting a calm, progressive driving style prevents excessive strain on the hydraulic system. 
3. Monitor the gearbox temperature constantly, especially on long trips or when driving in mountainous areas. 
4. Fix any small problem as soon as it appears before it turns into a major and costly failure, because the gearbox is one of the systems that deteriorates quickly when early faults are neglected.

Discover how to avoid degradation of your electric car’s battery with practical steps that protect its daily range and extend its life. Charging and heat issues can quickly threaten its performance, so how do you protect it?

How does keeping the charge level between 20% and 80% help extend battery life?

Maintaining the battery’s charge level helps as follows:

• Keeping the battery within this range prevents chemical stress inside the cells, because lithium-ion batteries work most efficiently when they are in the middle of the charge range rather than at its maximum or minimum.
• Repeatedly charging to 100% raises the voltage inside the cells, which leads to faster degradation of the battery’s active materials and, as a result, reduced capacity over time.
• Fully discharging to 0% puts the battery under heavy stress and makes the cells operate in unstable conditions, reducing their ability to hold a charge in the future.
• The best daily practice is to charge the car to 80% and use it down to 20% before recharging, as this reduces the number of full cycles and extends the battery’s lifespan.
• You can charge to 100% only when planning long trips, because this is occasional rather than daily use and therefore does not significantly affect battery health.

 

Does fast charging actually damage the battery in the long run?

• Fast charging generates high heat inside the battery, and this heat is the biggest factor in accelerating the degradation of the chemical cells, especially when it is repeated daily.
• It is best to use fast charging only when necessary or while traveling, because relying on it constantly increases the battery’s annual capacity loss.
• Slow (AC) charging at home is much gentler on the battery, because it raises the temperature gradually and gives the battery management system enough time to regulate the heat.
• Relying on fast charging every day can noticeably shorten battery life compared with slow charging, especially in cars without an advanced battery cooling system.
• Some modern cars precondition the battery before fast charging by raising or lowering its temperature to the optimal level, but frequent use is still not recommended for maintaining battery health.

 

How do high or low temperatures affect battery performance?

Temperature can affect battery performance as follows:

• High heat accelerates the chemical reactions inside the battery, causing faster capacity loss. It also increases the internal resistance of the cells, so the car consumes more energy.
• Extreme cold reduces battery performance and its ability to deliver power, lowering the car’s real-world range and increasing the energy used to warm the battery.
• It is always advisable to park the car in the shade or in an enclosed garage, especially in summer, as this reduces the battery’s exposure to high temperatures while parked.
• Avoid leaving the car fully charged in the sun for long periods, because high heat combined with a full charge is a very harmful combination for the battery.
• Using preconditioning while charging helps bring the battery to the right temperature before driving, reducing energy consumption later and keeping the cells stable.

 

What is the best driving style to preserve the battery and slow its degradation?

To preserve the battery, follow the best driving practices, including:

1. Sudden acceleration and high current draw quickly raise the battery’s temperature, which stresses the cells and shortens their lifespan. 
2. Calm driving at steady speeds keeps the electrical system stable and reduces energy consumption, which reduces the number of charging cycles per year. 
3. Using regenerative braking returns some energy to the battery, which reduces the need for frequent charging and indirectly extends battery life. 
4. Avoid repeated hard braking, as it consumes extra energy and reduces the effectiveness of regenerative braking, so energy is lost instead of recovered. 
5. Driving smoothly without sudden speed changes extends battery life, increases the car’s range and reduces the load on the energy management system.

 

How can you store an electric car correctly without harming the battery?

An electric car can be stored without harming the battery in several ways, including:

1. Do not leave the battery completely empty or fully charged during long-term storage, as both conditions put significant stress on the cells. 
2. The ideal storage level is between 40% and 60%, as this range keeps the chemicals inside the battery stable. 
3. Avoid leaving the car in very hot or very cold environments for long periods, because extreme temperatures directly affect battery health. 
4. If the car will be parked for more than two weeks, it is best to activate storage mode if available, as this mode reduces energy consumption and regulates the battery temperature. 
5. Checking the cooling system regularly ensures the battery stays in a stable environment during storage, reducing the chance of unexpected degradation.

 

Do software updates affect battery health?

• Manufacturers release software updates to improve heat and charging management, and these updates are often based on real data from thousands of users.
• Ignoring updates may deprive you of important battery-efficiency improvements, such as better heat distribution or adjusted optimal charging limits.
• Some updates automatically adjust charging limits to protect the cells, such as preventing a full charge in hot weather or reducing the charging speed when temperatures rise.
• It is best to enable automatic updates if available, because these updates may increase driving range and reduce energy consumption.
• Software updates may improve long-term battery performance by refining the algorithms that manage charging and discharging.

 

Why should battery health (SOH) be monitored regularly?

It is essential to monitor battery health regularly for several reasons, most importantly:

• The SOH indicator shows the battery’s overall condition and degree of degradation, and it is an important indicator of whether the battery is working efficiently or needs an inspection.
• A battery with health above 90% is considered excellent, while one below 70% needs close monitoring and possibly technical intervention.
• Regular checks help you detect any problem early, such as abnormal heating or rapid capacity loss.
• A drop in SOH may indicate misuse, excessive heat, improper charging or a problem with the cooling system.
• Some cars provide battery health reports through the onboard system or app, making it easy to monitor performance continuously.

 

How does tire pressure affect battery consumption and the car’s range?

The tire pressure can affect the battery as follows:

• Underinflated tires increase rolling resistance, raising energy consumption and forcing the battery to work harder.
• Higher consumption means more charging cycles and therefore faster battery degradation over time.
• Checking tire pressure weekly maintains the car’s efficiency and noticeably reduces energy consumption.
• Sticking to the manufacturer’s recommended values is essential, because every car is designed to operate within a specific pressure range.
• In hot weather, you may need to raise the pressure slightly to maintain performance, because the air inside the tire expands with heat.

 

Does the battery type affect its lifespan and how it is used?

• LFP batteries tolerate full charging better than NMC batteries, because they operate at a lower voltage and are subject to less stress.
• LFP batteries offer a longer life that can reach 3000–5000 charge cycles, making them an excellent choice for daily use.
• They operate more efficiently in hot climates, as they are less sensitive to heat than other types.
• They are safer and less prone to catching fire, making them a preferred choice in economy and mid-range cars.
• Choosing a car with an LFP battery is an excellent option for anyone who wants longer battery life without having to follow strict charging restrictions.

 

What daily habits extend battery life and maintain its performance?

The most important habits to follow to extend battery life include:

1. Avoid leaving the car fully charged overnight, because keeping a full charge for long periods raises the voltage inside the cells. 
2. Do not leave the car parked for long periods without running it, because the battery keeps consuming a small amount of energy even when the car is off. 
3. Use slow charging as much as possible, because it is gentler on the battery and reduces the heat generated by charging. 
4. Avoid aggressive driving or sudden acceleration, because it raises the battery’s temperature and increases energy consumption. 
5. Keep the battery temperature within the optimal range by parking in suitable places and using preconditioning when needed.
