Abstract

A power supply system for an electrified vehicle according to an exemplar aspect of the present disclosure includes, among other things, a primary power source and an auxiliary power source configured to selectively supply power in place of or in addition to the primary power source. At least one electrical connector is configured to connect the auxiliary power source to the power supply system.

Claims

1. A method, comprising:

activating an accessory system of an electrified vehicle, the electrified vehicle including at least one electric machine available for powering a wheel of the electrified vehicle;

receiving a signal during operation of the electrified vehicle indicative of a load selected by a user to be placed on an auxiliary power source;

offloading a portion of an energy demand of a primary power source to the auxiliary power source; and

powering the accessory system with the auxiliary power source while powering other loads with the primary power source,

wherein the accessory system is initially powered by the primary power source but is not powered by the primary power source while the energy demand is offloaded to the auxiliary power source.

2. The method as recited in claim 1, wherein the accessory system is one of a climate control system, a lighting system, a consumer device powering station, or an electrically driven system.

3. The method as recited in claim 1, wherein the auxiliary power source is a portable, gasoline driven generator.

4. The method as recited in claim 1, wherein the signal is automatically received in response to the load being entered into a cluster display located within a passenger compartment of the electrified vehicle.

5. The method as recited in claim 1, wherein the accessory system is activated by the user by turning on the accessory system within a passenger compartment of the electrified vehicle.
