How to maintain pure electric vehicles?

The difference between pure electric vehicle and traditional vehicle driving mode is that the traditional vehicle is mainly used for the maintenance of engine system, and the oil filter needs to be replaced regularly. Electric vehicles are driven by electric motors and do not need daily maintenance, such as oil, three filters and belts. They are mainly used for the daily maintenance of battery packs and motors and keep them clean.

1. Appearance and motor maintenance of pure electric vehicle:

First of all, it is necessary to carry out the appearance inspection of electric vehicle maintenance, including whether the steering wheel, safety belt, switch and combination instrument in the vehicle are normal, whether the functions of lamps and horns are normal, the aging degree of wipers and other components, and the inflation of tires. Wear, etc. Electric vehicles need to check antifreeze, brake fluid and glass water. Electric vehicles also have antifreeze, but unlike traditional vehicles, antifreeze is used to cool motors and needs to be replaced according to the time specified by the manufacturer. The general replacement cycle is 2 years or 40000 km. The type of antifreeze is the same as that of traditional vehicles. Gear oil (transmission oil) is the oil that needs to be replaced frequently in electric vehicles, but the replacement cycle of each manufacturer is different.

2. Maintenance of battery pack of pure electric vehicle:

This is the most important part of battery pack chassis inspection. The battery pack usually consists of about 100 individual batteries. In case of failure, the manufacturer usually provides professional repair. During vehicle maintenance, the 4S store will visually check whether the battery is damaged, and connect it to the computer to check whether the battery has any fault records.

In addition, all electric vehicles will be equipped with on-board terminal system to monitor the battery status of the vehicle and upload it to the manufacturer's server and government server. If the battery status is abnormal and there is potential danger, the owner will be notified. Chassis inspection includes chassis damage, deformation, screw looseness, oil leakage and other problems.
