System and Method of Powering an External Device with a Vehicular Battery System

A system and method of powering an external device with a vehicular battery system allows a user to charge electrically-powered devices with the electrical power source of his or her vehicle. The system includes an electrically-driven vehicle which includes a high-voltage battery. The high voltage battery includes a pair of contactors and is contained within a battery casing. The system further includes a junction box which includes an input derived from the pair of contactors, an external output for off-vehicle charging, and an internal output for on-vehicle charging. The system further includes a power modifier, an auxiliary low-voltage battery and at least one external device. The auxiliary low-voltage battery is electrically connected to the high-voltage battery through the junction box and the power modifier. Thus, the auxiliary low-voltage battery is safely charged by the high-voltage battery. The auxiliary low-voltage battery can then be used to power the external device.
