10.2 Redundancy BMS
The redundancy BMS has thresholds that are beyond the regular slave BMS thresholds stated in
section 10.1. When a critical redundancy BMS level is triggered, the master is informed that the
hard-wired interlock will be interrupted after 15 seconds. The Master BMS will go to fail-safe once
the hard-wired interlock loop is interrupted.
