  • System and method for energy prediction in battery packs
    Patent number: 9360527
    Abstract: In an embodiment, a system includes a battery management unit (BMU) coupled to a battery pack of an xEV. Further, the BMU is configured to determine an energy remaining value for the battery pack based, at least in part, on a minimum cell temperature and a minimum cell state of charge percentage (SOC %) determined by the BMU for the battery pack.
    Type: Grant

  • Pre-charging vehicle bus using parallel battery packs
    Patent number: 9350187
    Abstract: Systems and methods for pre-charging a bus capacitance in vehicles that receive at least a portion of their motive power from electricity generated from a battery are provided. By way of example, an embodiment includes a vehicle control unit (VCU) that receives battery pack data from a battery management unit (BMU) of each of a plurality of battery packs and determines, based on the battery pack data, which battery packs may be used to pre-charge the bus capacitance in parallel. The VCU issues commands to each of the BMUs to connect pre-charge circuits between each of the plurality of battery packs and the bus capacitance and receives status information from each of the BMUs to determine whether or not the bus capacitance was successfully pre-charged by the battery packs.
