Abstract: A battery control system includes a battery including: 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 ones of the first, second, and third terminals. A mode module is configured to set a mode to a first mode when a fault is present in a charging source of the battery. A switch control module is configured to control the plurality of switches based on a first predetermined capacity allotment when the mode is in the first mode.

Abstract: A battery of a vehicle includes a housing including: a lower portion that includes a plurality of separators extending vertically upward from a floor of the lower portion; and an upper portion that covers an opening of the lower portion and that is removable from the lower portion. The battery also includes: first and second terminals on the housing; third and fourth terminals on the housing; a plurality of individually housed batteries separated by the plurality of separators; a plurality of switches configured to selectively connect ones of the plurality of batteries to ones of the first, second, third, and fourth terminals; and a battery management module configured to control the plurality of switches.

Abstract: A battery enclosure shaped and sized to accept and surround a battery includes an outer case defining an aperture and having a base forming a bottom of the battery enclosure, the case having a first wall connected to a second wall, the second wall connected to a third wall, and a fourth wall portion connected to the first and third walls, each of the first, second, third, and fourth walls extending orthogonally from the base. The battery enclosure including a separable outer lid shaped to fit around the aperture of the case. The outer case and the outer lid having a material having thermal conductivity of less than about 0.3 W/mK, the battery enclosure has an air inlet selectively providing airflow to the battery enclosure and an air outlet selectively providing airflow from the battery enclosure, the outer case has a first thickness, the outer lid portion has a second thickness.
