Coolable battery system, method for cooling a battery and automobile comprising a coolable battery system
First Claim
1. A battery, comprising:
- at least one first integrated heat exchanger element configured for dissipating thermal energy from the battery;
said first heat exchanger element being disposed on the battery and having a first surface forming at least a portion of a surface of the battery;
said first heat exchanger element having a second surface with elevations and depressions distal from and opposite from said first surface forming the surface of the battery;
a first integrated coolant circuit configured to enable thermal energy to be exchanged between the battery and said first heat exchanger element;
a second heat exchanger element for each of said at least one first heat exchanger element;
said second heat exchanger element having a structured surface with elevations and depressions which are complementary to said elevations and depressions of said first heat exchanger element;
said elevations and depressions of said second heat exchanger element being disposed to be reversibly brought into thermal operative contact with said elevations and depressions of said first heat exchanger element;
a second coolant circuit; and
said second heat exchanger element being in operative thermal contact with said second coolant circuit.

Abstract
A battery includes at least one integrated first heat exchanger element that forms an integral part of the battery and is formed in one piece with the battery. The heat exchanger element can end flush with the surface of the battery, but it can also protrude from or be recessed into the surface of the battery. A coolable battery system includes at least one such battery and a second heat exchanger element for each battery that can be reversibly brought into thermal operative contact with the first heat exchanger element. A method for cooling such a battery in the coolable battery system, in which the first heat exchanger element of the at least one battery is brought in thermal operative connection with the second heat exchanger element, includes maintaining the second heat exchanger element at a lower temperature level than the first heat exchanger element.
