摘要： A system comprises a processor, configured to perform balancing on a commanded cell referring to a reference cell, and responsive to detecting balancing time exceeding a threshold time and state of charge (SOC) difference being above a tolerance, abort the balancing, and generate an error message. The threshold time depends on an average balancing time calculated using the SOC difference, a predetermined commanded cell capacity, and a predetermined balancing current.

摘要： An electrified vehicle includes a contactor having a coil operable by a low-voltage control signal to selectively electrically couple a terminal of a high-voltage bus to a charger receiving power from an external source. A programmed controller predicts the time it will take for the contactor to close after receiving a command based on the coil temperature and voltage of the command signal. The controller generates the low-voltage control signal responsive to a difference between bus voltage and charger voltage being less than a first threshold at the predicted closing time of the contactor. The control signal may also depend on the rate of change of the charger voltage being below a second threshold.

摘要： A controller, during charging of a traction battery by a remote charger, and responsive to a difference between a requested charge current and a current supplied by the remote charger exceeding a first threshold value for a predefined period of time, increases a requested charge voltage to a limit value. The controller further, responsive to a voltage across a capacitor and a voltage across the traction battery being same, and a voltage of the remote charger and the limit value being same, commands the remote charger to discontinue the charging.
