    摘要： A system and method for providing energy management and maintenance of a high energy battery pack that does not require installation of the battery pack into an operational EV. A battery service unit has multiple access mechanisms to charge or discharge a high energy battery pack through a primary or secondary high voltage port of the pack, irrespective of whether the battery pack is installed into an operating environment by adding a capability of providing a signature duplicating installation of the pack in the operating environment when necessary.

    摘要： An energy absorbing and distributing side impact system for use with a vehicle is provided, the system utilizing a battery pack enclosure that includes a plurality of cross-members (501A-H) that transverse the battery pack enclosure and absorb and distribute at least a portion of the load received when either the first or second side of the vehicle receives a side impact. The battery pack enclosure is positioned between the front and rear vehicle suspension assemblies and mounted between, and mechanically coupled to, vehicle structural members (e.g., rocker panels) located on either side of the vehicle. In addition to providing rigidity, strength and impact resistance, the battery pack cross-members segregate the batteries contained within the battery pack enclosure into battery groups.

    摘要： An apparatus in an electric vehicle including a propulsion electric motor powered by energy from an energy storage system, including a field oriented motor controller generating motor control signals for the electric motor, the motor control signals responsive to a flux command signal and a torque command signal; a torque command calculator, coupled to the motor controller, generating the torque command signal to command a desired torque; an optimal efficiency controller, coupled to the torque command calculator, generating an operating efficiency flux to operate the electric motor at a first determinable efficiency using a first power from the energy storage system while providing the desired torque; an excess dissipation controller generating an inefficient flux to operate the electric motor at a second determinable efficiency using a second power from the energy storage system independent of the desired torque wherein the second power is greater than the first power; and a mode controller setting the flux command signal using one of the optimal efficiency flux and the inefficient flux.
