What is the function of high-voltage control box for new energy vehicles?

The high-voltage control box assembly of Pacific Auto Network has the function of anomaly detection, which is simple in structure, high in reliability and good in safety, and users can conveniently detect anomalies by themselves. Controlling the connection or disconnection of the main power line of the controller is helpful to protect the safety of the circuit and the controller.

Manufacturing method of high-voltage control box assembly of new energy vehicle document number: 13023907 Navigation: X Technology >; The utility model belongs to the technical field of high-voltage system design of new energy vehicles, in particular to a high-voltage control box assembly of new energy vehicles.

At present, because there are many high-voltage electrical equipment in the structure of new energy vehicles, the high-voltage control box assembly is widely used to complete the distribution of high-voltage power supply for vehicles.

In the past, high-voltage control box components generally had the following defects:

1, the connection with the high-voltage wire harness is mostly bolted, which leads to the complicated and time-consuming disassembly and assembly steps of the wire harness;

2. There is no function of detecting the connection state and opening the cover of the high-voltage system, so the maintenance personnel may directly contact the high-voltage electricity, which has certain security risks;

3. The shielding layer of the high-voltage wiring harness needs to be hydraulically connected to the shell of the high-voltage main control box by the assembler, so the shielding performance of the whole machine cannot be guaranteed;

4. The waterproof performance of the whole machine can not be guaranteed by tightening the Glenn head by the assembler;

5. The high-voltage relay lacks the corresponding freewheeling diode, which makes the high-voltage relay lack protection when it is disconnected, which has a certain impact on the life of high-voltage relay and transistors on the line;

6. Lack of protection for high-voltage parts and low-voltage parts such as the shell, and the risk of high-voltage and low-voltage contact during vehicle collision.

Technical realization factors: In view of the above shortcomings of the prior art, the utility model aims to provide a high-voltage control box assembly for new energy vehicles. ..
