Description

The BMS harness is the "data highway" of the battery system, and its core functions are divided into four categories:

Cell status acquisition: Collect voltage and temperature data of individual cells to provide basic data for SOC (State of Charge) and SOH (State of Health) estimation.
Communication and command transmission: Enables CAN/LIN communication between BMS and vehicle control unit (VCU), charging system, and motor controller to transmit control commands and fault information.
High-voltage safety monitoring: responsible for high-voltage interlock circuits, insulation detection signal transmission, monitoring the integrity of high-voltage circuits, and preventing the risk of high-voltage leakage.
Actuator control: Transmits relay/contactor drive signals to control the on/off state of the high-voltage circuit, ensuring safety during the charging and discharging process.

Application

The BMS assembly wire harness for new energy vehicles is a dedicated low-voltage wire harness assembly for the battery management system (BMS) of new energy vehicles. It is the "nerve center" connecting the battery pack, BMS controller, and the vehicle system, and plays a key role in signal acquisition, communication transmission, and safety monitoring.
