Frequently Asked Questions (FAQ)

Q: How is the passive balancing uniquely managed on this module?

The ESBMM-3612 implements a 100mA passive balance achieved through controlled discharging of multiple cells within the rack simultaneously. Crucially, the dissipated energy of each individual cell can be precisely measured for better system analytics.

Q: Can this BMS control external cooling systems directly?

Yes. It is equipped to support fan speed control, fan state feedback, and speed detection, making it highly suitable for air-cooled energy storage cabinets where thermal regulation is actively managed by the BMS.

Q: What is the monitoring scale for cells and temperatures?

This high-capacity slave module supports cell-level voltage monitoring for 36 cells and pairs this directly with 36 NTC (10K) temperature monitoring points, guaranteeing a strict 1-to-1 thermal mapping.

Q: How does it communicate external signals?

Alongside its internal monitoring, the board is designed to support 1 digital signal output and 1 digital signal input detection, allowing seamless integration with external alarms or system triggers.
