What is the difference between the scrapping process of new energy vehicles and traditional vehicles?

The use and maintenance of new energy pure electric vehicles are different from traditional fuel vehicles. This paper focuses on the maintenance process of new energy pure electric vehicles.

There are some differences between the driving modes of electric vehicles and traditional fuel vehicles. The biggest difference between the two is that the traditional fuel vehicle is mainly aimed at the maintenance of the engine system, and it needs to change the oil and mechanical filter regularly. The electric vehicle is driven by a motor, which does not need routine maintenance such as engine oil, machine filter and belt. It is mainly to maintain the battery pack and motor daily and keep them clean. This shows that the maintenance of electric vehicles is indeed much easier than traditional fuel vehicles.

Maintenance steps are as follows:

Step 1: Visual inspection.

The maintenance of electric vehicles should first be visually inspected, including whether the steering wheel, seat belt, switch and instrument cluster in the car are normal, whether the functions of lighting and horn are normal, the aging degree of wiper and other components, tire inflation, damage and wear.

Step 2: Liquid inspection.

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 the motor and needs to be replaced according to the time specified by the manufacturer. The general replacement period is 2 years or 40,000 kilometers, and the types of antifreeze are exactly the same as those of traditional fuel vehicles.

Gear oil (gearbox oil) is the oil that needs to be changed frequently for electric vehicles, but the replacement cycle of different manufacturers is different. Generally, the replacement cycle is 1 year or 20,000 kilometers.

Step 4: Check the system.

Mainly check the battery pack, which is the most important part of chassis inspection. Generally, battery packs are composed of hundreds of independent batteries, and manufacturers usually carry out professional maintenance when faults occur. When the vehicle is being maintained, professionals will visually check the battery damage, wiring, etc. , and connect the computer to check whether the battery has a fault record. In addition, electric vehicles sold in the market will be equipped with on-board terminal systems to monitor the battery status of vehicles and upload them to manufacturers' servers and government servers. The manufacturer can monitor and collect fault information for maintenance at any time, and the owner will be notified by the service personnel of the manufacturer when the battery state is abnormal and potentially dangerous.

Maintenance step 5: engine room inspection.

The particularity of electric vehicles is basically the control device and wiring harness. Although there is some waterproof protection, the computer room must not be washed and cleaned with water. It can be cleaned by blowing, wiping or using a special cleaning solution.

As can be seen from the above table, the maintenance project of pure electric vehicles is extremely simple. In addition to replacing worn parts and some engine oil, it is only necessary to check the vehicle with a computer.

The maintenance period of brake fluid is 2 years or 40,000 kilometers, and the replacement cost is about 150 yuan.

The maintenance period of gear oil is 1 year or 20,000 kilometers, and the replacement cost is around 220 yuan.

Others, such as brake fluid, antifreeze and so on. , are replaced or added at a lower cost, tens of dollars.

Generally speaking, compared with traditional fuel vehicles, the use cost and maintenance cost of electric vehicles have great advantages. Although the vehicle structure is complex, its maintenance is very simple. In addition to replacing worn parts and some engine oil, it is only necessary to check the vehicle with a computer.
