Abstract: A thermal control system for use in an electric vehicle includes a reservoir in fluid communication with a first loop having a first loop component and a second loop having a second loop component. First and second pumps are operable to circulate a liquid coolant to the first loop and the second loop, respectively. A first valve, a second valve, and a third valve are moved between alternate liquid coolant flow positions by a vehicle control unit to selectively change the first and second loops from a parallel orientation to a series orientation providing alternate methods to reclaim or exhaust excess heat generated by the first loop component or to provide redundancy in order to maintain operation of the first loop and the second loop in the event of a failure of the first pump or the second pump.

Abstract: A system includes a first bus, a second bus, a first battery that includes a first plurality of cells, and a second battery that includes a second plurality of cells, wherein the second battery is connected to the second bus. A first converter connects the high-voltage battery to the first bus. A second converter connects the first bus to the second bus. A controller is configured to control operation of the first converter and the second converter.
