Abstract
The invention relates to a device for heating the interior of an electric vehicle having an air-cooled high-temperature battery. Waste heat form the battery is supplied to the interior via a liquid circuit having a heat exchanger which can be controllably bombarded by the waste air from the battery and by fresh air. The liquid circuit is also connected to and cools heat-generating components of the electric drive system.
Claims6
Device for heating an interior of an electric vehicle having an air-cooled high-temperature battery, comprising:
- a liquid circuit;
- a first heat exchanger coupled in thermal communication with said liquid circuit;
- means for controlling a flow of fresh air through said first heat exchanger and for controlling a flow of exhaust air from said battery through said first heat exchanger;
- and
- a second heat exchanger arranged in said liquid circuit for transferring heat to air in an interior of said electric vehicle;
- said liquid circuit being coupled in thermal communication with heat generating components of an electric drive system of said electric vehicle to absorb waste heat therefrom, at a point downstream from said second heat exchanger relative to a flow direction of said liquid circuit.
