SEAMLESS SWAPPING OF CHARGER FORWARD AND REVERSE MODES

Systems and methods for operating a battery charger are described. A controller can operate a battery charger under a forward mode. Under the forward mode, a power supply is connected to the battery charger to provide power to a load and to charge a battery. The controller can determine an anticipation of removal of the power supply. In response to determining the anticipation, the controller can enable a reverse mode of the battery charger. When the reverse mode is enabled, the power supply remains connected to the battery charger to provide power to the load and charging of the battery is suspended. The controller can further determine at least one configuration of the reverse mode of the battery charger.
