Battery pack low voltage wiring harnesses have voltage requirements

It is my honor to answer your question I am Shanghai Keying method to share relevant technical information for you from a professional point of view, I hope to help you. High-voltage interlocking: This category generally refers to high-voltage connections, generally new energy vehicles high-voltage charging connections will need to have interlocking devices to ensure the safety of charging. Battery pack wiring harness is generally divided into two pieces, one is the high current system, one is the weak system, which is generally through the high current piece of current ranging from 200A ~ 300A, because of different models of different design, the general current is not the same, the piece can be based on the actual situation to consider separately. Weakness system generally refers to the communication, this piece of the reliability of the product puts forward higher requirements, one of the important points is the waterproof problem, which intuitively affects the subsequent performance of many, the section Yingfa general protection requirements must meet the standard requirements of IP67 and above. bms harness, OBC harness this is mainly the lifeline of the body, generally on the wiring harness structural design of the requirements of the changes made, especially the terminal Crimping, which directly affects the electrical performance, the general science and technology will use a special terminal tension test tool for destructive test test. The above is the reply, hope to help you. Part of the local reference citation:/view/0c00a81e5627a5e9856a561252d380eb6294233c.html?from=search
