How to maintain an electric car: battery, tyres and brakes

First published in May 2024; reviewed and translated in October 2026. Charging and maintenance requirements vary by model: the manufacturer’s instructions take priority.

Maintaining an electric vehicle is essential to preserving its performance and service life. Although electric cars generally require less maintenance than combustion vehicles, several key components still need attention. This detailed guide helps you take care of your electric car.

1. Checking an electric vehicle’s battery

The battery is central to an electric vehicle. Follow the charging limit recommended for your model and battery type in the manual or on the vehicle’s screen: the 20–80% rule is not universal. Avoid leaving the vehicle almost empty or fully charged for long periods unless the manufacturer advises otherwise. Use compatible equipment and reserve rapid charging for situations where it is useful. If you notice an unusual reduction in range or a warning, arrange a diagnosis with a qualified professional.

2. Inspecting the tyres

Tyres are essential for safety and energy efficiency. Correct pressure helps preserve range by reducing rolling resistance. Check pressures at least monthly and adjust them to the manufacturer’s recommendations. Regularly examine the tyres for uneven wear, which may indicate an alignment or suspension problem. Rotate tyres where the manufacturer recommends doing so, to promote even wear. Replace them when the wear indicator reaches its critical threshold, usually visible on the tyre itself.

3. Maintaining the braking system

Regenerative braking recovers energy during deceleration, but it does not replace mechanical brake maintenance. Have brake pads, discs and fluid checked according to the manufacturer’s intervals and operating conditions. Using the mechanical brakes less frequently does not eliminate corrosion. Unusual noise, a warning light or reduced braking effectiveness requires professional inspection. Do not top up brake fluid without following the instructions specific to the vehicle.

4. Cleaning charging connectors

Visually inspect the cable, plug and charging port while the vehicle is unplugged. Follow only the manufacturer’s cleaning procedure: do not insert objects or liquids into the contacts. If you notice cracks, corrosion, abnormal heat or damage, stop using the affected equipment and have it inspected by a professional.

5. Updating the software

Software updates are common in modern electric vehicles and can bring significant improvements to features, battery management and safety. Regularly check whether updates are available and install them as soon as possible. Updates may also fix bugs and improve the vehicle’s overall performance.

6. Checking the battery cooling system

Thermal management helps keep the battery within its operating temperature range. Monitor vehicle warnings and possible signs of leaks without opening or working on the battery cooling circuit. Checks and work on this circuit must be carried out by a qualified professional in accordance with the manufacturer’s maintenance schedule. Not all electric vehicles have the same cooling system.

7. Checking fluids

Although electric vehicles need fewer fluids than petrol models, some remain essential. Check and refill windscreen washer fluid as instructed in the manual to maintain visibility. Brake fluid and cooling circuit checks must follow the manufacturer’s instructions and be entrusted to a professional where specified. Do not work on the traction battery or high-voltage components.

Conclusion

Maintaining an electric vehicle requires particular attention but remains simpler than maintaining a conventional car. Following these steps helps maximise efficiency, safety and durability. It also makes driving more enjoyable while reducing unnecessary garage visits.
