POWEROAD Multi-level BMS

POWEROAD BMS has been designed to safely and reliably manage different chemistry lithium-ion batteries, and is a full and mature solution for Commercial & Industrial (C&I) or Utility Energy Storage System (ESS) application. It gathers cell protection & balancing, self-diagnosis, insulation guard and communication, which is compatible with international mainstream interfaces.

POWEROAD BMS is designed in 3-tier architecture, from M-BMS for Battery Module, to C-BMS for Battery Cluster, and to A-BMS for Battery Array.

A-BMS is assigned as the Master-BMS, to masters its Slave BMS: C-BMS, while C-BMS masters its Slave BMS: M-BMS. M-BMS monitors, balances and controls a group of battery cells within the battery module. And C-BMS manages the modules within the battery rack.

Its multi-level BMS separate mechanism ensures the independent management strategies for system operation with the high safety and stability.
