Abstract: A method for estimating a virtual distance corresponding to power supplied by an electric vehicle (EV) to offboard loads includes monitoring one or more enabling conditions comprising at least one of a speed of the EV, an active/inactive mode for supplying power to one or more V2X loads, a net charging/discharging state of a battery of the electric vehicle, a plug-in charging state of the electric vehicle, and a wirelessly charging state of the electric vehicle. In response to the one or more enabling conditions, selectively integrating power output at least one of by the battery of the EV to the offboard loads and at the one or more V2X loads to generate an integrated power output value and converting the integrated power output value to a virtual distance.

Abstract: A charging system for an electric vehicle includes: a memory configured to store terminal clamp voltage (CV) and a cutoff current (CC) combination pairs; a charging receptacle configured to connect to an offboard charging station; and an onboard charging circuit. The onboard charging circuit includes: a high-voltage direct current bus connected to a rechargeable energy storage system; and a control module configured to communicate with the offboard charging station and determine charging capabilities of the offboard charging station and the onboard charging circuit, to select one of the CV and CC combination pairs based on the charging capabilities of the offboard charging station and the onboard charging circuit, and to initiate charging of the rechargeable energy storage system based on the selected one of the CV and CC combination pairs.
