The PCU integrated with the high-voltage box can monitor and manage battery clusters internally and
complete information exchange externally.
The main functions of the PCU are as follows:
Battery information management: PCU can monitor cell voltage, cell temperature, cluster voltage,
cluster charging current, and cluster discharging current in real-time.
SOC estimation: Estimated the battery cluster SOC.
DI/ DO communication: PCU provides multiple DI and DO interfaces.
CAN and RS485 communication: PCU provides 3 CAN communication interfaces and 2 RS485
communication interfaces.
Self-fault diagnosis: PCU has a self-test function.
Charge and discharge management: PCU can coordinate the charge and discharge between battery
clusters and improve the circulating current in clusters.
