Product Features
• Integrate functions such as battery data sampling, fault diagnosis, and datamanagement into one unit.
• The two-tier architecture of the BMs system supports 2 isolated CAN channels, 2isolated RS485 channels, and l Fast Ethernet communication channel.
• 3-channel voltage sampling, 4-channel temperature sampling, and the maximumvoltage at the cluster end is up to 1500 V.
• Built-in soc/sOH multi-dimensional algorithm accurately tracks the battery's actualstate.
• Support for battery (single cell, module, cluster) overvoltage, undervoltage, voltagedifference, overcurrent, undercurrent, overtem- perature, undertemperature,
shortcircuit, insulation alarms and protections.
• Supported local and online program upgrade.
