With the wide application of new energy electric vehicles, the capacity, safety, health status and range of the battery are increasingly becoming the focus of attention.

Battery management system is a system for monitoring and controlling the battery, providing real-time feedback of collected battery information to the user, and adjusting the parameters according to the collected information to give full play to the performance of the battery.

BMS battery system is composed of master board, slave board, BDU, high voltage control board and so on. 

New energy vehicles generally use distributed: a master control box and several slave control boxes together.

The master control box is only connected to the communication line, the master is responsible for the collection of the signal line, to provide power lines to the slave board and other necessary wiring harness.

Slave control box, arranged in their own responsible for the collection of temperature, voltage battery module accessories, the collected signals through the CAN line report to the master control module.

There are battery modules that directly make the voltage and temperature acquisition wires inside the module and lead them out with a wire-to-wire connector.

When the battery pack is assembled, the connector can be plugged in directly.

The quality of BMS battery system products determines the performance of major new energy vehicles, the production of BMS battery system also put forward higher requirements.
