Abstract
A battery system including at least one battery cell having an interior and having at least one exterior surface is provided with at least one cooling plate that is positioned in engagement with the exterior surface for absorbing heat from the interior of the battery cell. A cooling tube is thermally coupled to the cooling plate for absorbing heat from the cooling plate.
Claims21
A battery system for use in an electric vehicle, comprising:
- at least one battery cell having an interior and at least one exterior surface;
- at least one cooling plate in engagement with said at least one exterior surface for absorbing heat from the interior of said at least one battery cell;
- and
- a cooling tube thermally coupled to said at least one cooling plate for absorbing heat from said at least one cooling plate wherein a liquid coolant flows through said cooling tube.
