In addition to the power battery as the driving device, the maintenance of other parts of the new energy vehicle is also different from that of the traditional fuel vehicle.

Oil maintenance

Different from traditional motor vehicles, the antifreeze of new energy vehicles is mainly used to cool the motor, and its battery and motor need to be cooled and dissipated by adding coolant. Therefore, the owner also needs to replace it regularly. Generally, the replacement cycle is two years or after the vehicle has traveled 40,000 kilometers.

In addition, during maintenance, in addition to checking the coolant level, the northern cities also need to perform a freezing point test, and if necessary, replenish the original coolant.

Chassis maintenance

Most of the high-voltage components and battery units of new energy vehicles are centrally installed on the vehicle chassis. Therefore, during maintenance, special attention should be paid to whether the chassis is scratched, including whether the connection of various transmission components, suspension and chassis is loose and aging.

In the daily driving process, you should drive carefully when encountering potholes to avoid scratching the chassis.

Car cleaning is important

The interior cleaning of new energy vehicles is basically the same as that of traditional vehicles. However, when cleaning the exterior, avoid water entering the charging socket, and avoid flushing with large water when cleaning the front cover of the vehicle. Because there are many “water-afraid” high-voltage components and wiring harnesses inside the charging socket, water may cause a short circuit in the body line after the water flows in. Therefore, when cleaning the car, try to use a rag to avoid damaging the circuit.

In addition to the above tips, car owners should also check their vehicles regularly during daily use. Before departure, check whether the battery is sufficient, whether the braking performance is good, whether the screws are loose, etc. When parking, avoid the sun exposure and humid environment, otherwise it will also affect the battery life.
