New energy high-voltage interlocking battery pack wiring harness

It is my honor to answer your question

I am Shanghai Keyingfa to share the relevant technical information with you from a professional point of view, and I hope to help you.

High-voltage interlock: This type generally refers to high-voltage connection, the general new energy vehicle high-voltage charging connection will need to have an interlock device to ensure the safety of charging.

The battery pack wiring harness is generally divided into two pieces, one is the high-current system, one is the weak system, which the high-current piece of the general through the current in the 200A ~ 300A ranging from the design of different models is not the same, the general current is also not the same, which can be based on the actual situation to be considered separately. Weakness system generally refers to the communication, this piece of the reliability of the product puts forward higher requirements, which is an important point is the waterproof problem, which intuitively affects the subsequent performance of a lot of science and technology to welcome the law in general this piece of the protection requirements must meet the standard requirements of IP67 and above.

BMS wiring harness, OBC wiring harness is mainly the lifeblood of the body, the general design of the wiring harness structure to put forward changes in the requirements, especially the terminal crimping, which directly affects the electrical performance, the general science and technology will be the use of special terminal tension test tool for destructive test test.

The above is the reply, expect to help you.
