  • Expandable energy storage control system architecture
    Patent number: 8245801
    Abstract: A hybrid electric vehicle drive system comprises a first power bus electrically coupled to a motive power subsystem and a drive wheel propulsion assembly; a second power bus electrically coupled to the first power bus and a plurality of energy storage subsystems, wherein the first power bus is configured to allow electrical power to be transmitted among the motive power subsystem, the drive wheel propulsion assembly, and the second power bus, and wherein the second power bus is configured to allow electrical power to be transmitted among the plurality of energy storage subsystems and the first power bus.
    Type: Grant

  • Propulsion Energy Storage Control System and Method of Control
    Publication number: 20110100735
    Abstract: A propulsion energy storage control system and method of control interspersed between a heavy duty hybrid-electric drive system and its propulsion energy storage. The control system having an energy storage DC bus, electrical interfaces to the drive system and a plurality of propulsion energy storage subsystems, DC-to-DC converters at each interface, and a controller configured to operate each DC-to-DC converter independently such that power flow may charge, discharge, and shuttle between the plurality of propulsion energy storage subsystems.
