BAT1 Cell Voltage Power reset of the system is required.
Sensing Data Hold If the symptom still occurs after reset, repair
Protection of BMS or PCS Control Board is necessary.
BAT1 Cell or Rack When the maximum cell or rack voltage is
Over Voltage Protection above protection level, thus terminating the
system. Automatically returns to normal
when the maximum cell or rack voltage goes
below the limit value.
BAT1 Cell or Rack When the minimum cell or rack voltage is
Under Voltage below protection level, thus terminating the
Protection system. Automatically returns to normal
when the minimum cell or rack voltage goes
above the limit value.
BAT1 Cell Over Temp When the maximum cell temperature is
Protection above protection level, thus terminating the
system. Automatically returns to normal
when the maximum cell temperature goes
below the limit value.
