Very deep discharge and shutdown sequence after loads were not disabled by the ATD signal
Note that this sequence describes an atypical situation that does not occur in a correctly configured system. Below chart indicates
the stages the BMS goes through when the battery is discharged very deep, well past the moment when the battery under voltage
alarm was activated. This situation occurs when not all loads are not disabled by the ATD signal. The cell voltages in this chart
are the default voltages.
