|
The low voltage (LV) battery internal protection transistor (MOSFET) is open, while the LV battery is at low state of charge and recovering the MOSFET is not being attempted. As a result, the low voltage battery management system (LVBMS) continues to draw power from the cells, which may make the LV battery unrecoverable if it is not disconnected soon.
|
The LV battery state of charge (SOC) is less than 30%, the LV battery internal protection transistor (MOSFET) is open, and there are no low voltage battery management system (LVBMS) communication or firmware mismatch issues.
|
The LV battery may become too deeply discharged and unrecoverable.
