BMS Voltage Window Checker

Validate cell voltage limits, pack window, and balancing start thresholds.

How this works
V_pack,min = S * V_cell,min, V_pack,max = S * V_cell,max
Methodology

Pack voltage limits: V_pack,min = S × V_cell,min, V_pack,max = S × V_cell,max. Balancing thresholds set at configurable ΔV above min-cell voltage per industry best practices.
