Abstract

The invention provides a battery signal acquisition wire harness with a bending structure. The battery signal acquisition wire harness is simple in structure. A battery bump can be prevented from pulling the battery signal acquisition wire harness or the battery signal acquisition wire harness can be prevented from being damaged by the vibration of a battery module operating in a bad working condition for a long time, thereby ensuring the service life of the battery signal acquisition wire harness. The battery signal acquisition wire harness includes a circuit board which is a flexible circuitboard. A plurality of connecting pieces are arranged on the circuit board at intervals. The circuit board is connected to a battery individual through the connecting pieces. The circuit board is provided with a temperature sensor, and the circuit board is connected with a connector. The battery signal acquisition wire harness is characterized in that bending portions are arranged on the circuit board at intervals along a width direction of the circuit board. In addition, the present invention also provides a bending process of the battery signal acquisition wire harness with the bending structure.

Description

technical field [0001] The invention relates to the technical field of power batteries, in particular to a battery signal acquisition wire harness with a bending structure and a bending process thereof. Background technique [0002] In the field of automobiles, as the problems highlighted by traditional energy are becoming more and more serious, automobile exhaust emissions have become one of the main pollution sources of smog in my country. Features such as convenience, quickness and recyclability are widely used. Especially in the application process of electric vehicles, in order to obtain high power and large capacity, it is often necessary to connect single cells in series and parallel to form a battery module. [0003] In order to ensure that the battery module can work normally, the vehicle management system needs to monitor the battery module in real time, collect the voltage signal of each single cell in real time, and evaluate the performance of each cell. The bat...
