You may have heard repeatedly that electric vehicles (EVs) are cheaper to own and run because they don’t rely on fossil fuels and are easier to maintain. Now, the first part is a no-brainer, not needing to fill your car up with gas is a big relief on your wallet with fuel prices on the constant rise. However, the second part of that statement needs some explanation
Some people have gotten it in their heads that because EVs have fewer moving parts than an internal combustion engine (ICE) vehicle, they won’t have to maintain it, just like an electric appliance. In this article, we’re going to explain why EVs aren’t maintenance-free and what exactly is being done in an EV service.
Do EVs need maintenance?
Yes, definitely. Despite the aforementioned simpler design, EVs still require some maintenance, though they won’t need it as frequently as an ICE vehicle. The most crucial aspect is the battery, which should be monitored for performance and degradation over time. Additionally, the brake system, particularly the brake fluid, should be inspected, even though brake pads and rotors may last longer due to regenerative braking. EVs also need maintenance for their cooling systems, which prevent the battery and motor from overheating.
Fluids such as coolant, brake fluid, and windshield washer fluid still need to be checked and replaced when necessary. The cooling system plays a critical role, especially in temperature regulation of the battery and electronics, and should be inspected regularly. EVs are highly dependent on software, so regular updates to improve vehicle efficiency, safety, and connectivity are crucial. Also, like any other car, tires need to be rotated and aligned to ensure even wear, and suspension components and steering systems should be inspected for wear and tear. Tires may also need to be checked more frequently with EVs as the instantaneous torque they provide could wear them out faster as compared to ICE cars.
What does an electric car service involve?
Since EVs have fewer oily components than normal cars, what parts do technicians need to look at when you pull your EV in for a service?
An electric car service focuses on maintaining the core components that drive the vehicle's performance, mainly the battery, electric motor, and software systems. Battery health is paramount, as it's the most expensive and critical part of the car, so services often include diagnostic checks to monitor its performance, charge levels, and potential degradation over time. Technicians also inspect the high-voltage electric cables for wear and proper insulation, ensuring no issues with the electrical system. Another significant part of EV service is the cooling system, which keeps the battery at an optimal temperature. Electric motors themselves are relatively low-maintenance, but checking for wear and ensuring that they’re operating efficiently is part of the routine.
How often does an EV need to be serviced?
Depending on the brand of EV you own the answer could be different. Most manufacturers recommend a service interval of about 12 months or every 20,000 km, whichever comes first. However, some brands like Tesla and BMW don’t specify a fixed service schedule. Instead, these manufacturers equip their EVs with diagnostic systems that notify drivers when maintenance is required. This allows the vehicle to monitor its own condition and prompt service visits based on actual needs, rather than following a predetermined timeline.
If you’re unsure of when your EV needs to be serviced, it’s best to check with your owner’s manual and conduct visual checks on consumables to see if your electric vehicle is due for a mechanic’s visit.
