HV Slave BMS
Modular Battery Module Acquisition Units (BMU / Slave modules) providing millivolt-precision cell voltage sensing, multi-channel temperature monitoring, and active/passive balancing.
HV Slave BMS modules (BMUs) are directly mounted on individual battery modules or cluster trays. They deliver ultra-accurate cell voltage and temperature telemetry, execute cell balancing commands, and transmit real-time telemetry back to the Master BMS unit.
