Because electric cars have fewer moving parts compared to petrol or diesel vehicles, drivers often assume they don’t need servicing.
Servicing an electric vehicle is still essential; it just looks a little different to what you might be used to.
The experts at CJ Auto reveal exactly what happens when you book an electric car service.
How different is servicing an electric car versus a petrol or diesel car?
Regular car servicing is quite different if you have an EV – there is no engine oil to change and no exhaust system to check. However, they have their own unique set of components that need regular attention, including the battery, motor, and brakes. A full electric car service checks all of these things to keep your car safe, roadworthy, and insurable.What is checked during an electric car service?
Specific to servicing electric cars, our experienced team will check wires and loose connections, as well as the following:High-voltage (HV) battery
Technicians check the condition of the car’s main battery, including looking at how well it holds charge and checking for signs of degradation.Brakes
As they use regenerative braking, EVs slow themselves down by feeding energy back into the battery rather than relying solely on brake pads. This means they last much longer than in a petrol/diesel car but still need to be checked, as they can seize or corrode from being used less often.12V battery
Alongside the main battery, cars have a smaller 12V battery, like combustion engines. This battery powers the lights, infotainment system, and central locking, so it is also checked as part of a service.Tyres, suspension, and steering
EVs are heavier than diesel or petrol cars because of the battery, leading to faster tyre wear. Tyre condition, tread depth, and pressure are checked, as well as suspension and steering.Coolant systems
Electric cars rely on a coolant system to keep the battery and motor at the right temperature, keeping them running efficiently and safely. This is checked and topped up, much like coolant in a traditional engine.How often should you service an electric car?
Most EV manufacturers recommend a service every 12 months or after 12,000 miles – whichever comes first. This is similar to a petrol or diesel car. This brings many benefits, including:- Catching issues early
- Ensuring your car remains safe for you, your passengers, and other road users
- Helping you pass MOTs
- Spreading the cost* of necessary car maintenance
