摘要： A vehicle charging system includes a charger configured to adjust an output voltage to achieve a voltage request and output a measured output voltage. The vehicle charging system further includes a controller programmed to measure a terminal voltage of a traction battery being charged and receive the measured output voltage from the charger. The controller is further programmed to output the voltage request as a sum of a full charge voltage and an estimated voltage measurement error between the measured output voltage and the terminal voltage.

摘要： This disclosure describes vehicle systems and methods for controlling charging of an auxiliary (i.e., low voltage) battery of an electrified vehicle. Exemplary charging methods may dynamically adjust a low voltage setpoint of a power converter during the low voltage support. The proposed systems and methods therefore achieve constrained low voltage support by controlling the power drawn by the power converter at an appropriate level during the low voltage support.

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.
