The RD772BJBCANFDEVB is a battery junction box (BJB) reference design with CAN FD communication. It is meant for rapid prototyping of a high-voltage battery management system (HVBMS) hardware and software. This board contains two MC33772C battery sensors for redundant high voltage and current measurements and performs isolation measurements.
The junction box controls the high-voltage connections for the charging system, inverter/motor, and battery pack. High-voltage connections, currents, and isolation resistance are measured within this module and sent back to the main ECU for SOC and power calculations, monitoring vehicle status, and ensuring safety during various vehicle conditions.
