CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The BCU monitors and manages individual battery cells or modules within a Battery Management System. It collects data on voltage, current, and temperature, executes cell balancing, and communicates with the main BMS controller to ensure safe and efficient operation.
The BCU operates over a supply voltage range of 9–36 V DC and a temperature range of -40 to 85 °C. It can be stored at temperatures from -40 to 105 °C. It is designed to withstand vibration per ISO 16750-3 and has an IP67 ingress protection rating.
The BCU typically uses CAN 2.0B (ISO 11898) for communication, and also supports UART and I2C. It sends status information and receives commands from the BMS master controller.
You must verify model-specific values such as supply voltage, temperature ranges, measurement accuracy, communication interfaces, isolation voltage, and mechanical specifications with the legal manufacturer. Standards listed are references, not guarantees of compliance.
