ABSTRACT:
A vehicular electrical system for a hybrid electric vehicle provides a high voltage electrical system having a high power electrical energy storage device (HPD) and a power inverter that cooperate to provide power to a hybrid electric vehicle propulsion system; and a low voltage electrical system having a low voltage power source, at least one accessory power load, and a control switch that toggles between an opened and a closed position to control the flow of current flowing between the low voltage power source and the HPD. A method of using the vehicular electrical system provides the step of using the HPD and power inverter to provide power to the electric vehicle propulsion system; and opening a control switch to isolate the low voltage system from the high voltage system and closing a control switch to charge the HPD.
