  • CONTACTOR DAMAGE AND DIAGNOSTICS
    Publication number: 20220337070
    Abstract: A method includes interpreting a contactor open event and a contactor load value for a contactor positioned on a motive power circuit for a mobile application, determining that a contactor opening event under load has occurred in response to the contactor open event and the contactor load value, and updating a contactor wear condition in response to the contactor opening event under load, wherein updating the contactor wear condition comprises accumulating a number of the contactor opening events under load.

  • POWER DISTRIBUTION AND CIRCUIT PROTECTION FOR A MOBILE APPLICATION HAVING A HIGH EFFICIENCY INVERTER
    Publication number: 20200274375
    Abstract: A power electronics assembly for a mobile application includes a first power electronics component selectively coupled to a high source on a first side and coupled to a high voltage battery on a second side, a second power electronics component selectively coupled to one of a low load or a low voltage battery on a first side and coupled to the high voltage battery on a second side; and a controller, including an operating mode circuit structured to determine a discharge operating mode for the mobile application, a power electronics configuration circuit structured to provide a switch state value for the first power electronics component and the second power electronics component in response to the discharge operating mode, and wherein the first power electronics component and the second power electronics component are responsive to the switch state value to coupled selected ones of the high source, low load, and low voltage battery to the high voltage battery.

  • Apparatus and method for smoothing of vehicle drivelines
    Patent number: 6565479
    Abstract: A method for and apparatus for preventing oscillations of a vehicle. The engine speed is monitored and filtered, the filtered engine speed being compared to a natural frequency of the vehicle. The natural frequency corresponds to a gear ratio of the vehicle. A torque command is provided to an electric machine coupled to a driveline of the vehicle, the electric machine provides a counteracting torque to the driveline in order to eliminate oscillations in the vehicle.

  • Method for diagnosing battery condition
    Patent number: 5739670
    Abstract: A method for diagnosing the general condition of a battery module in a string of such modules comprising a battery pack monitors voltage, current and temperatures of the modules and battery pack. Accumulators account for various charge quantities including charge out and net charge used for the battery pack as well as discharge period durations. State of charge is provided by appropriate means and used to update module capacities. The various charge and time accumulators are used to derive depth of discharge and discharge rate information providing inputs to predetermined functions for determining a simple scalar outputs directly indicative of the general condition of the modules.
