EV and Hybrid Car Service: What You Should Know
Electric cars are not maintenance-free. Learn what should be checked during EV and hybrid service in Helsinki.
EV and hybrid car service is different from traditional combustion engine maintenance. Electric cars have fewer moving engine parts, but they also have more electrical systems, software, high-voltage components and charging-related parts that require the right expertise.
In Helsinki, EVs and hybrids are often used for short trips, cold-weather driving and city traffic. This makes battery condition, brakes, tyres, heating systems and charging reliability especially important.
What is checked during EV service?
An electric car does not need engine oil changes in the same way as a combustion car, but that does not make it maintenance-free. Important checks include brakes, suspension, tyres, wheel alignment, cabin filter, cooling systems, software-related warnings and battery condition.
- 12 V battery condition and charging system operation
- general high-voltage battery condition and warning messages
- charging port, cables and connector condition
- brake function and prevention of sticking brakes
- tyre wear and wheel alignment
- air conditioning and heating system operation
Why does a hybrid need special attention?
A hybrid combines a combustion engine, electric motor, high-voltage battery and complex control systems. Service therefore requires understanding of both mechanical and electrical systems. A starting problem, for example, can be related to the 12 V battery, high-voltage system or engine control.
Traditional maintenance is still important in hybrids: oils, filters, brakes and cooling systems. At the same time, the electric drivetrain, charging behaviour, battery temperature management and fault codes must be considered.
When is a high-voltage battery test useful?
A high-voltage battery test is useful if range has clearly decreased, charging has become slower, the car shows battery warnings or you are buying a used EV or hybrid. A test helps understand battery condition better than the dashboard percentage alone.
For a used electric car, battery condition is one of the most important value factors. A pre-purchase check can therefore be a smart decision, especially if the car has high mileage or the charging history is unclear.
Charging problems are not always caused by the charger
If an EV does not charge normally, the cause can be the cable, charging station, vehicle charging port, 12 V battery, software or the onboard charging system. Before replacing parts, the system should be checked step by step.
CarBit’s EV charging problem diagnostics helps determine whether the issue comes from the car or from the external charging environment.
FAQ about EV and hybrid service
Is an electric car maintenance-free?
No. Although there are fewer engine-related service items, brakes, suspension, tyres, battery, cooling and electrical systems still need checks.
Can any workshop service an EV?
Not every job requires opening the high-voltage system, but EV and hybrid work still requires proper knowledge and a safe working process.
Why should EV brakes be checked?
EVs often use regenerative braking, which means mechanical brakes can stick or wear unevenly if they are not checked regularly.
