A backup unit you can interrogate, not just trust.
The BMS is where backup either earns confidence or hides problems. Ours reports every series group's voltage and every temperature probe continuously, estimates state of charge to half-a-percent class, and speaks your protocol — so the fleet dashboard sees the battery as clearly as the switch.
Per-cell eyes. Fleet-level voice.
Sampling runs at cell-group resolution across all 16 series groups (and scales up through our HV platform), with protection thresholds enforced in hardware — independent of any software state.
- Voltage per series group, temperature per probe zone — streamed, not polled
- SOC to 0.5%-class accuracy; SOH trended per cycle record
- Hardware-enforced over-charge, over-discharge, over-current and short-circuit protection
- Alarm ladder from warning to contactor drop, each step logged
Speaks to what you already run.
| Parameter | VB-5125 / VB-E3 BMS |
|---|---|
| Primary bus | CAN 2.0B, 250/500 kbps — register map documented |
| Secondary | RS485 Modbus RTU for plant controllers |
| Network | SNMP v2c/v3 via shelf controller — DCIM and scheduler friendly |
| Node telemetry | PMBus on VB-E3 for in-band server integration |
| SOC / SOH | 0.5%-class SOC; SOH trended against cycle log |
| Events | Time-stamped alarm ladder, retrievable over any interface |
| Security option | GPS positioning + remote lock-down for unmanned or theft-prone sites |
| Integration docs | Register map, SNMP MIB and Modbus map supplied with samples |
Weak cells announce themselves early.
Cell-level drift is the earliest signal a backup fleet gives you — months before runtime falls short. Continuous per-group telemetry turns that signal into a maintenance ticket instead of a 3 a.m. incident, and keeps parallel shelf groups sharing load honestly.
