Control systems and methods for battery with adjustable capacity

A battery control system, comprising:

• a battery comprising:
• first, second, and third terminals;
• a plurality of individual groups of two or more battery cells;
• and
• a plurality of switches configured to connect ones of the individual groups to and from the first terminal, to and from the second terminal, and to and from the third terminal;
• a mode module configured to set a mode to a first mode when a fault is present in a charging source of the battery;
• and
• a switch control module configured to control the plurality of switches based on a first predetermined capacity allotment when the mode is in the first mode, wherein the switch control module is configured to control the plurality of switches such that:
• a first one or more of the individual groups are connected to the first terminal and provide a first operating voltage via the first terminal;
• a second one or more of the individual groups are connected to the second terminal and provide a second operating voltage via the second terminal;
• and
• a third one or more of the individual groups are connected to the third terminal and provide a third operating voltage via the third terminal,
• wherein the first operating voltage is 48 Volts, the second operating voltage is 12 Volts, and the third operating voltage is 12 Volts.
