Pure electric vehicles are different from traditional cars, there is no engine and gearbox powertrain, there is no need to replace spark plugs, oil changer filters, etc. Electric vehicles' batteries, motors and electronic control systems are the core, all have manufacturer's warranty, all electric vehicles The maintenance is based on routine maintenance, such as whether the circuit is aging, dusty, loose screws, etc. By the way, check the tires, air conditioning filter, brake pads, etc.
The current electric car routines are 7500 or 10,000 km maintenance, divided into A and B maintenance, A and B alternately. The cost is slightly cheaper than the traditional car, the price depends on the brand, there is not much oil and Filter replacement, only take some work hours, let's talk about the items that need to be checked during maintenance.
First, the battery power system:
1. Security protection
2. Insulation inspection
3. Connector status
4. Bolt tightening torque
5. Power battery heating function check
6. External cleaning inspection

The above are all items to be inspected during maintenance of electric vehicles. Class A maintenance must be done for these items. Class B maintenance is part of the routine, and other conditions depend on the situation.
Take a closer look, in fact, the maintenance steps of electric vehicles are also very cumbersome, of course, this is no way, since it is a car owner, the car maintenance must be extremely fancy, the car is like a woman, 'not only to marry her home, but also to take care of She has been a lifetime, this is the most attractive moment for men!
