What maintenance needs to be done for new energy vehicles

1. The battery needs to be replaced regularly with antifreeze. The motor needs to be replaced with gear oil regularly, and the bearings and parts that need to be replaced in other electrical control systems need to be lubricated and maintained in time, and the system data needs to be optimized.Check the oil. There is no oil in pure electric new energy vehicles, but brake fluid, coolant, and various lubricants still exist.

2. New energy vehicles refer to vehicles that use batteries or other non-fossil fuels as energy, such as electric vehicles, hybrid vehicles, etc. Because the power system of new energy vehicles is different from that of traditional vehicles, different maintenance is required.

3. As the power source of new energy vehicles, the battery is one of the most important parts. It should be checked and maintained at the repair shop regularly. Improper maintenance or daily use will cause battery loss, and replacing the battery is also a cost.

4. Of course, the first part that needs frequent maintenance is the power battery pack. The importance of the power battery pack to new energy vehicles is self-evident.

5. [Pacific Automobile Network] Oil and liquid inspection Although pure electric vehicles do not have engines, their batteries and motors also need to be added with coolant to cool down and dissipate. During maintenance, in addition to checking the liquid level of the coolant, a freezing point test should also be carried out, and the original coolant should be replenished if necessary. Detection of high-voltage electrical components.

6. The four seasons change, and people need to maintain their health according to the season. Cars also need to be maintained according to the season. Many car owners know the maintenance of gasoline cars, but they know nothing about the maintenance of new energy vehicles.

Do electric vehicles need maintenance?

Of course they need maintenance. Although there is a big difference between new energy vehicles and gasoline vehicles in terms of power output mode, daily maintenance is still necessary. Both are guaranteed.The difference in maintenance: gasoline vehicles are mainly aimed at the maintenance and cleaning of the engine system, the regular replacement of the oil filter, etc. Electric vehicles are mainly for the maintenance of batteries and motors.

It needs maintenance. Routine maintenance costs 300 or 400 yuan, and major maintenance costs about 1,500 yuan. Pure electric vehicles need regular maintenance and maintenance. Although it does not need to change the oil and oil filter regularly like fuel cars, there are still brake fluid, antifreeze and glass water and other oils in the car, and also There is an air conditioner that needs to be maintained in time.

Electric vehicles need maintenance. Electric vehicles do not need to replace the oil and engine filter. It needs to regularly replace the steering oil and brake fluid of the vehicle, add glass water, replace the air conditioning filter, and frequently check the vehicle chassis and circuit system. If there is damage, it should be repaired in time.

Basically, there is no maintenance, and the key power battery needs maintenance.

The biggest difference between pure electric vehicles and fuel vehicles is the difference in the power system, so traditional cars are not required for engine maintenance, such as oil, "three filters", spark plugs, etc. Pure electric vehicles mainly carry out daily maintenance of battery packs and electric motors, and generally focus on checking and eliminating problems.

What items can be done for the maintenance of electric vehicles?

1. The routine maintenance of electric vehicles mainly includes the following items: Battery maintenance: The battery of electric vehicles is one of the core components and needs to be checked and maintained regularly. This includes checking the power status of the battery and ensuring that the batteryFully charged, check whether the battery connectors and wiring are corroded and loose, and whether the battery is overcharged or overdischarged.

2. Although there is no engine in pure electric vehicles, the inspection of its circuit system is very important. The maintenance items of the circuit system generally include power battery system, motor system, electrical control system, etc. The battery needs to be replaced with antifreeze regularly.

3. The maintenance items of new energy vehicles are mainly: circuit maintenance, chassis maintenance, tire maintenance, oil maintenance, air conditioning maintenance, etc. Circuit maintenance Circuit maintenance is to check the power battery system, check the motor system, check the electrical control system, and troubleshoot according to the situation.

4. The maintenance items of electric vehicles are as follows: routine maintenance includes three-electricity inspection, chassis inspection, light inspection and tire inspection.Small maintenance mainly inspects the three-electric system, chassis and lights, which can basically be completed in 1-2 hours.
