Abstract
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.
Claims7
A electrically powered vehicle system comprising:
- a positive power rail connectable to a positive terminal of a battery;
- a negative power rail connectable to a negative terminal of the battery;
- a bulk capacitor located in series with a switching device and connected between said positive power rail and said negative power rail such that said bulk capacitor and said switching device are electrically connected in series between said positive power rail and said negative power rail;
- a heater having a heating resistance connected in series with a heater switch and being electrically connected between said positive power rail and said negative power rail such that said heater and said heater switch are electrically connected in series between said positive power rail and said negative power rail and such that said heater and said heater switch are arranged in parallel with said bulk capacitor and said switching device between said positive power rail and said negative power rail;
- and
- a link electrically connected between a first point between said bulk capacitor and said switching device to a second point between said heater and said heater switch.
