Abstract
A vehicle system includes a voltage converter configured to electrically isolate and convert power transferred between high voltage (HV) and low voltage (LV) busses, and a controller configured to, responsive to regenerative power exceeding a charge power limit of a traction battery receiving charge via the HV bus, increase an output voltage of the converter to initiate transfer of some of the regenerative power to an auxiliary battery connected with the LV bus.
