Abstract:
An on-board charger (OBC) for charging a traction battery of an electric vehicle includes a Power Factor Correction (PFC) stage to convert AC power from a mains supply into DC power for use in charging the traction battery, a bi-directional DC/DC converter coupled to the traction battery, a DC link capacitor between the PFC stage and the DC/DC converter, and a controller. The controller is operable to control the PFC stage and the DC/DC converter to operate in (i) a pre-charge mode in which the DC link capacitor is pre-charged using electrical power from the traction battery and (ii) a stable operation mode in which the traction battery is charged using the AC power from the mains supply.

Claim (Index 3):
The OBC of  claim 1  wherein:\n the PFC stage is connectable to the mains supply by an Electric Vehicle Supply Equipment (EVSE); and \n the controller is further operable to request the EVSE to not connect the PFC stage to the mains supply while the DC link capacitor is being charged using electrical energy from the traction battery.
