The Prospects of New Energy Vehicle Maintenance Technology

Again, the New Energy Vehicle Maintenance Major will help promote the development of the entire automobile industry. . As one of the important development directions of the automobile industry in the future, the quality of maintenance services of new energy vehicles directly affects the healthy development of the entire automobile industry.

The prospect of new energy vehicle maintenance is very broad. Because new energy vehicle technical engineers are in short supply in the industry, many enterprises are willing to spend a lot of money to find people. Those who have participated in the formal training of new energy vehicle maintainers, can work with a license and have certain experience.

Employment prospects for new energy vehicle maintenance majors: From the perspective of development prospects, the employment prospects for new energy vehicle maintenance majors are bright. At present, China is implementing the development strategy of "resource-saving and environmentally friendly", and the state is implementing key support policies for new energy vehicles.

Precautions for the maintenance of new energy vehicles?

1. Maintenance personnel need to prepare basic insulation safety tools, such as power inspection, discharge tooling, insulation partitions, etc. To wear necessary safety protective equipment, such as insulating gloves, insulating shoes, insulating pads, protective glasses, etc., its voltage resistance level must be greater than 1000V.

2. Electric vehicles are strictly prohibited from being exposed to the sun. An environment with excessive temperature will increase the internal pressure of the battery and cause the battery to lose water, causing a decrease in battery activity and accelerating the aging of the electrode plate. Precautions for electric vehicle maintenance - regular deep discharge. Regular deep discharge of the battery is also conducive to activating the battery, which can slightly increase the capacity of the battery.

3. Take up a license and set up a guardian. Maintenance personnel of high-voltage electric vehicles must hold a low-voltage electrician certificate, and it is recommended to set up a guardian. Guardians also need to obtain a low-voltage electrician certificate. The guardian supervises the whole process of the operation. Two. Standardize the operating environment. There shall be no items unrelated to the work in the operating environment. Unrelated personnel are not allowed to enter the scene.

Notes on the maintenance of new energy vehicles

1. In the process of vehicle maintenance, the safety operation procedures of the circuit must be observed. Precautions for the use of new energy vehicles: 1. Avoid high-current discharge. When electric vehicles start, carry people and go uphill, try to avoid banging and acceleration, resulting in instantaneous high-current discharge. High-current discharge is easy to cause the crystallization of lead sulfate and destroy the physical properties of the battery pole plate.

2. The following are the precautions for the maintenance of new energy vehicles: the high-voltage switch needs to be turned off before maintenance; during the operation process, if the maintenance of the power system is involved, the power supply must be cut off. During the maintenance of new energy vehicles, you should pay attention to turning off the high-voltage switch before maintenance, and abide by the safety operation procedures of electrical lines during maintenance.

3. Take up a license and set up a guardian. Maintenance personnel of high-voltage electric vehicles must hold a low-voltage electrician certificate, and it is recommended to set up a guardian. Guardians also need to obtain a low-voltage electrician certificate. The guardian supervises the whole process of the operation. Two. Standardize the operating environment. There shall be no items unrelated to the work in the operating environment. Unrelated personnel are not allowed to enter the scene.

4. 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.

5. During overhaul, the power supply must be cut off first, and insulation tools must be used for inspection and repair. Grounding must be carried out before operation to avoid the danger of electric shock. Secondly, pay attention to detailed maintenance, especially the maintenance of the battery. The battery is the core component of new energy vehicles, which needs to maintain sufficient power, good storage environment quality, stable charging operation, etc.

6. Fuel vehicles are mainly for the maintenance of the engine system, and regularly replace the oil, filter, etc. New energy vehicles are driven by motors, and routine maintenance items such as oil and belts are naturally omitted. Only the battery pack and motor need to be maintained to keep them clean.
