3-Tier Hierarchical Topology of HV BMS System

The energy storage monitoring system adopts three-level hierarchical control with clear logical layers:

Bottom Layer: BMU cell monitoring units collecting cell voltage & temperature data
Middle Layer: RBMS rack master controller managing all cells in a single battery cabinet
Top Layer: SBMS system central controller uniformly managing up to 15 RBMS rack masters

For small-scale single-rack energy storage projects, the system can be simplified into a 2-layer structure (BMU + RBMS only) without SBMS.

Safety Rules for Installation & Maintenance

High-voltage DC circuits are built inside the equipment. Only authorized professional technicians are allowed to disassemble the chassis.
After secondary high-voltage protection is triggered, wait at least 1 minute before re-closing the breaker.
Close the DC switch on the PCS side first, then power on the RBMS master to avoid impulse current.
All maintenance work must use insulated tools.
Do not modify factory pre-set core parameters arbitrarily.
In case of fire, only dry powder fire extinguishers or fire sand are permitted.
Disconnect the main circuit breaker if the system remains idle for a long time.
