  • Publication number: 20250145048
    Abstract: One or more controllers, after activation of a vehicle, may charge and discharge a traction battery according to power limits that are based on polarization voltages describing internal states of the traction battery and that are a function of polarization voltages present at a last deactivation of the vehicle and decay values having time constants that are based on a state of charge of the traction battery and a temperature associated with the traction battery.

  • Publication number: 20240399923
    Abstract: A traction battery controller of an electrified vehicle dynamically adjusts an estimation gain based on a state-of-charge (SOC) of the traction battery and controls the vehicle according to an operating characteristic of the traction battery estimated from an equivalent circuit model of the traction battery that depends on the estimation gain. The controller may reduce the estimation gain while the SOC is low or high and may otherwise maintain the SOC. The controller may dynamically adjust the estimation gain based further on a temperature of the traction battery. The operating characteristic may be a power capability of the traction battery or an updated SOC of the traction battery.

  • Patent number: 12115869
    Abstract: One or more controllers limit direct current output by electric vehicle supply equipment to charge a traction battery of a vehicle according to a filtered current squared capacity remaining of the traction battery, which may be defined for a window of time having a predefined duration and be based on an average current input to or output from the traction battery.

  • Patent number: 11603011
    Abstract: A vehicle includes a traction battery and a controller. The controller is programmed to, in response to dynamic resistance and capacity of the traction battery for a drive cycle differing from dynamic resistance and capacity of the traction battery for a previous drive cycle by threshold percentages, controlling the traction battery to reduce lithium plating.

  • Patent number: 11342603
    Abstract: A vehicle includes a traction battery and a battery cooling system arranged to cool the battery. A controller of the vehicle is programmed to, responsive to current of the battery exceeding a current threshold and a temperature of the battery being less than a threshold temperature, activate the battery cooling system to cool the battery.

  • Patent number: 10926661
    Abstract: A vehicle includes a processor programmed to create a virtual energy bucket for a battery, and set a short-term power limit corresponding to the virtual energy bucket that defines a discharge limit for the battery. The virtual energy bucket fills responsive to an output power of the battery being below a first power threshold and depletes responsive to the output power being above a second power threshold.
