Zusammenfassung:Provided herein is a controller for a low voltage disconnect (LVD), a method of protecting and providing a maximum or substantially maximum battery reserve coupled to a DC load bus and a power system manager. In one embodiment, the LVD controller includes an adaptive disconnect system configured to determine a variable LVD threshold voltage value and instruct the LVD to disconnect a battery reserve from a DC load bus based thereon. The variable LVD threshold voltage is determined based on a current of the battery reserve during a battery-discharge event.
