Battery management system and method for extending time until a battery reaches an over-discharged state during storage of an information handling system
A computer-implemented method extends the time until the battery reaches an over-discharged state of an information handling system during storage. The method comprises determining if a first battery parameter is outside an associated first battery parameter specification. When the first battery parameter is outside the associated first battery parameter specification, a power management controller isolates the battery by turning off a charge/discharge field effect transistor. The method also includes determining if the first battery parameter is outside an associated second battery parameter specification. In response to the first battery parameter being outside the associated second battery parameter specification, the power management controller is triggered to enter a minimum power state to further reduce power consumption from the battery.
