VEHICLE ELECTRICAL SYSTEM TO CHARGE CAPACITORS

An electrically powered vehicle system including a battery, the terminals of which supply positive and negative power rails, and including a bulk capacitor located in series with a switching device, and being electrically connected between the power rails. A heater having a heating resistance is connected in series with a heater switch, and is electrically connected between the power rails. A link is electrically connected between a point between the bulk capacitor and the switching device to a point between heating resistance and the heater switch.
