Electric Car Maintenance

Although electric vehicles (EVs) require less maintenance than most internal combustion engine vehicles (ICE), they still require regular servicing. Here is a detailed overview of the maintenance needs of an EV:

Battery Maintenance

Since extreme temperatures can degrade battery performance in electric vehicles, most EVs are equipped with thermal management systems to maintain optimal battery temperature. It is important to avoid exposing your EV to extreme heat or cold for prolonged periods.

To extend battery life, avoid frequent use of fat chargers. Although these may seem convenient, fast charging can degrade the battery more quickly than standard 120 or 240-volt charging.

Also, avoid fully charging or completely depleting the battery regularly. Changing the battery to around 85% - 90% for daily use can help prolong the battery's health.

Regularly monitor the battery’s health using the vehicle’s onboard diagnostics. Some manufacturers recommend periodic professional inspections to ensure the battery and its management system are functioning correctly.

Electric Motor Maintenance

Electric motors are simpler and have fewer moving parts than traditional engines, which reduces the need for frequent maintenance. However, some parts still require regular checks.

Some EVs use coolant to keep the motor and other components at optimal temperature. It is important to check coolant levels regularly and flush the system as recommended by the manufacturer.

Another aspect that helps optimise motor performance and efficiency is managing the vehicle’s software updates. Manufacturers often release updates that can be installed over the air or at service centres.

Brake System Maintenance

Electric vehicles use regenerative braking, which helps with recharging the battery and reduces the wear on traditional brake components in EVs.

Regularly check and replace brake fluids as specified by the manufacturer. Although EVs use their mechanical brakes less frequently, the fluid still needs occasional replacement to ensure safety and performance.

Regenerative braking reduces wear on brake pads and rotors, but they still require regular inspection. In areas with harsh weather conditions, it is advisable to lubricate brake callipers to prevent corrosion.

Tyre Maintenance

Tyre wear and maintenance are crucial for all vehicles, including EVs. Check the tyre pressure regularly to ensure optimal performance and safety. Evs are heavier than traditional cars due to their batteries. This can lead to faster tyre wear due to the weight.

Occasional tyre rotation and alignment can help distribute wear evenly, which extends the life of the tyres. Depending on the driving conditions and the manufacturer’s recommendations, the tyres may need to be replaced more frequently.

Fluid Maintenance

Despite having fewer fluids than internal combustion engine vehicles (ICE), Eclectic vehicles still require certain fluid replacements.

For EVs that use a liquid cooling system, checking and replacing the coolants is essential. It is best to follow the manufacturer’s guidelines for intervals. Another fluid that requires regular refills is the windshield washer fluid. It is advisable to also change the windshield wipers occasionally to ensure clear visibility.

Cabin Air Filter Maintenance

The cabin air filter ensures clean air inside the vehicle. Most manufacturers recommend replacing the cabin air filter every 12 months. This can vary based on your driving conditions, especially if you are driving in areas with high pollution or dust.

Software and System Updates

Since electric vehicles rely heavily on software to manage various systems, it is essential to stay in the loop with any new updates released by the manufacturer. Many EV manufacturers provide over-the-air software updates that can enhance vehicle performance, add new features and fix existing bugs. Ensure your vehicle’s software is up to date to benefit from the latest improvements.

You can also use the car’s diagnostic tools to monitor the health of various systems. Regular checks can help identify potential issues early.

The maintenance savings of electric cars are considerably substantial as compared to traditional fuel vehicles. This is primarily due to their simpler design and fewer moving parts.

While traditional combustion engines contain around 2000 moving parts, an electric vehicle’s powertrain operates with fewer than 20 moving parts. This simplicity results in reduced wear and tear, which makes maintenance significantly cheaper.

The main electric car maintenance cost is related to the battery pack, which gradually loses its ability to hold a charge over time. Typically, a lithium-ion battery provides a reliable driving range of over 100,000 km before requiring replacement.

In contrast, gasoline or petrol cars demand regular maintenance for their complex engines, which includes oil changes, filter replacements and frequent repairs for parts or sometimes even replacements. Despite the initially higher purchase price for EVs, their lower maintenance costs and fewer repair needs make them more economical over time compared to petrol cars.

Following a regular maintenance schedule for your electric vehicle helps ensure optimal performance, extend battery life and save on long-term electric car maintenance costs. Here is a detailed overview of what your EV maintenance should include:

Monthly Check-Ups

There are three main checks that you should conduct monthly :

Tyre Pressure- Regardless of your vehicle type, checking the pressure of each tyre is essential to maintaining the quality of your drive. However, with EVs, since the battery adds to the weight of the vehicle, it is advisable to check your tyres to ensure that they are inflated to the manufacturer's recommended levels. This helps improve your car's range and safety.

Tyre Tread Wear- The weight of the car can cause excess tread wear in some spots. Regularly check the tyres to prevent uneven wear and potential punctures or bursts, as they can be dangerous.

Windshield Washer Fluid- Ensure that your windshield washer fluid is filled for clear visibility.

Beyond the monthly check-ups, here is what your electric vehicle service schedule should include as per your EVs mileage:

For 8,000 km to 11,000 Km

• Change the lubricants for moving parts to prevent sludge and carbon buildup. This ensures smoother operation of the vehicle.

• Ensure all lights are functioning and replace any that are damaged or show signs of wear.

• Check the cabin AC, power inverter and other electronic components. Also, inspect the steering, brakes, chassis, suspension, drive shaft and power steering for any unusual damage or wear.

• Rotate the tyres to ensure even tread wear, which can depend on the vehicle’s body type.

• Inspect the coolant level and top up if necessary to keep the electric motor and battery cool.

For 25,000 Km

• Inspect the transmission fluid to ensure smooth gear changes.

• Replace cabin air filters to maintain air quality inside the vehicle and prevent dust contamination.

• Replace wiper blades for effective windshield cleaning.

For 48,000 Km

• Flush out the old coolant and replace it with fresh fluid to maintain the cooling system’s efficiency.

• Replace the power steering fluid to ensure easy handling and responsiveness.

• Flush and top up brake fluids to maintain braking performance and safety.

• Note: It is important to note that the schedule may vary depending on factors like the manufacturer’s recommendations and model type.
