Electric car: what maintenance is required?

If advertisers pull out the no-maintenance card for electric cars to sell them to us, the fact remains that an electric vehicle still requires a minimum of maintenance.



vIndeed, if on electric cars, by their design, no more fluid changes, no filter changes, less brake wear, simplified transmission and above all no engine wear which leads to the replacement of many various parts, the fact remains that electric vehicles have many systems similar to thermal vehicles: whether it is the suspension, the steering or the braking system.


A saving on maintenance of up to 40% compared to a thermal vehicle and only 20 points to replace which we will detail for you.


The brakes


Electric cars (like hybrid cars) have a regenerative braking system that recovers energy when braking on hybrid and electric vehicles. It allows you to recharge the battery while driving and increases the vehicle's range. Regenerative braking also helps the vehicle slow down without using the brakes, unlike combustion cars as we know them today.

The regenerative braking system requires special attention. The brakes of electric vehicles are less stressed than those of thermal vehicles. To prevent the brakes from corroding, he recommends regular maintenance every 30,000 km or every 2 years.

Replacing the brakes on an electric car has some specificities related to the regenerative braking system and electrical components that must be taken into account during replacement.



Engine consumables


In the engine compartment, if there is no longer any need for oil as for combustion engines, it is a fully electric vehicle, there is still a reduction gearbox, which is a type of transmission which requires a certain amount of maintenance periodic to do.

Many electric vehicle models have a battery with a liquid thermoregulation system. Again, there, it is antifreeze that must be changed, the electric vehicle will present problems which are directly linked to the same types of problems that one would have with a gasoline vehicle.



Mechanical organs


Because an electric car is generally 30% to 35% heavier than a gasoline equivalent, all underbody parts like the suspension and steering are under more pressure and it is important to check them. It's the same with the air conditioner, which works in conjunction with the drive system to regulate the battery temperature.



The rest of the components to check


These are simple routine checks to be carried out every 30,000km (or before depending on the case), they are the same as thermal vehicles because as we have pointed out to you, they have the same components:

- checks of the shock absorber condition;

- tire wear;

- filtering system;

- checking the level of fluids: brakes, cooling, windshield wipers, etc.


If even the maintenance and its costs make you dream, the repair of an electric vehicle becomes more complex when the repair work affects the charging port, the inverter, the battery or other systems which require the intervention of a specialized automotive technician.

The main failures come from modules with faulty voltage.

Batteries: the heart of the vehicle

This is the most important point to take into account, there is no maintenance to be carried out, however this does not mean that the batteries are eternal, on the contrary, once worn out they must be replaced and the cost replacement can easily approach the price of a small electric car!
