Huawei FusionDC1000A - Battery Module

current equalization and intelligent voltage equalization. Old and new battery
strings can be used together, ensuring reliable system operation.
● Implements intra-cabinet and inter-cabinet communication, collects sampling
signals from battery modules, and collects voltage and current signals from
the battery cabinet.
● Protects against exceptions such as overvoltage, undervoltage, overcurrent,
overtemperature, undertemperature, and leakage current in the battery
cabinet.
NO TE
Only the BCU with the BOM number 02313PYT-001 supports online leakage current
detection.
