Abstract: A power distribution system for a vehicle includes contactors that selectively electrically couple a charger to a high-voltage bus. The contactors are closed at the start of a charge event in an order that alternates for successive charge events. Upon completion of the charge event, the last closed contactor at the start of the charge event is opened first and a weld check is performed. If the weld check is indicative of a welded contactor, then the weld check is performed on the other contactor.

Abstract: A vehicle includes a traction battery. A controller is configured to operate the traction battery according to a capacity estimate. The capacity estimate is based on a difference between a current-based estimation and a voltage-based estimation of a change in battery state of charge over a time interval. The difference is evaluated over a predetermined number of time intervals. When more than a predetermined percentage of the differences exceed a threshold, the capacity estimate is updated based on an average of the differences.

Abstract: A vehicle includes a traction battery and a controller. The controller is programmed to output an age value of the traction battery based on a ratio of a reference capacity value to an initial reference capacity. The reference capacity value is derived from a mean and a standard deviation of a plurality of historical battery capacity values and has a predetermined probability of being less than an actual battery capacity. The controller is programmed to adjust a battery control strategy based on the age value. The vehicle includes an instrument cluster that is configured to display the age value.

Abstract: A vehicle includes a traction battery having a plurality of battery cells and a balance circuit configured to selectively discharge one or more of the battery cells. A controller is programmed to estimate charge capacities of the battery cells and determine a standard deviation of the estimated capacities. The controller is further programmed to determine a skewness of the estimated capacities. The controller is also programmed to, in response to the skewness exceeding a first threshold, command the balance circuit to discharge one or more of the battery cells when a state of charge (SOC) of the traction battery is less than a second threshold, and, in response to the skewness being less than the first threshold, command the balance circuit to discharge one or more of the battery cells when the SOC of the traction battery is greater than the second threshold.

Abstract: A vehicle includes a traction battery having cells and at least one controller. The controller is programmed to charge and discharge the traction battery according to a net current for the traction battery derived from sets of temperature-based current values, each of the sets corresponding to a different one of the cells, and each of the values for a given one of the sets corresponding to a different zone of the cell.

Abstract: A vehicle includes a traction battery. The vehicle further includes a controller programmed to generate a capacity estimate of the traction battery and, in response to an amount of energy supplied to the traction battery during a charge cycle being less than an estimated amount of energy stored in the traction battery during the charge cycle, detect that the capacity of the traction battery has changed and alter an operating strategy of the traction battery until the capacity estimate is updated.

Abstract: A vehicle includes a battery pack, an electric motor, and a contactor to electrically connect the pack and motor. The contactor is configured with a control circuit to electrically connect the pack and motor. The control circuit includes a leak detection sensor. The vehicle further includes a controller to output a leakage resistance associated with the pack. The leakage resistance is based on a voltage of the pack and a leak voltage detected by the sensor while the contactor is closed.

Abstract: A battery management system for a vehicle includes a controller programmed to charge a battery at a predetermined charge current. The controller activates an electrical load to discharge the battery for a predetermined time in response to a charge current of the battery becoming less than the predetermined charge current at a predetermined voltage limit. After discharging for the predetermined time, the controller resumes charging at the predetermined charge current. A current magnitude during the discharge and the predetermined time may be based on factors including the predetermined charge rate, a battery temperature, and a charge current magnitude during charging.
