  • Publication number: 20240017627
    Abstract: A virtual high voltage interlock is disclosed that utilizes a software-based function (e.g., an electronic control unit) to determine if there are any open wires or connectors, based on voltage signals reported by internal components, to prevent high voltage exposure. The electronic control unit instructs a power source to charge a DC bus to a safety voltage, receives measured voltage readings, via a control area network, from at least one high voltage component coupled to the DC bus, and provides an operating voltage to the DC bus in response to the measured voltage readings being acceptable.

  • Patent number: 11787306
    Abstract: An electrified vehicle, system, and control method include a traction battery having a first plurality of cells and a second plurality of cell monitoring circuits each having an associated at least one of the first plurality of cells, and a controller configured to control the cell monitoring circuits to measure voltage of the associated cells at an initial frequency until a state of charge (SOC) of the traction battery is established, and to measure voltage of the associated cells at a second frequency based on the SOC after the SOC is established to reduce heat generation of the cell monitoring circuits. The cell monitoring circuits may be controlled to asynchronously measure associated cell voltage and/or to reduce voltage/current conversion time when delta cell voltage and battery pack current are below respective thresholds.

  • Patent number: 11654793
    Abstract: A vehicle includes a traction battery and a controller. The controller, responsive to some cells of the traction battery achieving a first state of charge threshold, discharge other cells of the traction battery, each having a capacity greater than each of the some of the cells, to a second state of charge threshold that is greater than the first state of charge threshold without discharging the some of the cells. The controller then charges all of the cells at the same time such that the some of the cells and the other of the cells achieve a same predetermined target state of charge at a same time.
