Battery module wire harnesses mainly include high voltage wiring harnesses and low voltage wiring harnesses, which respectively bear different functions and design requirements on new energy vehicles.
The low-voltage harness is mainly responsible for battery status estimation, temperature monitoring and signal transmission. Low voltage harness design solutions include:
BMU (BMS mainboard) wiring harness:mainly responsible for battery status estimation (SOC, SOH, etc.).
Temperature monitoring harness:responsible for monitoring the temperature of the battery module to ensure that the battery is operating within a safe range.
signal transmission wiring harness:responsible for transmitting control signals and other relevant information to ensure the normal operation of the battery syste.
In addition,the battery module also includes some important accessories and components,such as the harness isolation board and laminated busbars.The wire harness isolation board i…
