COOLABLE BATTERY SYSTEM, METHOD FOR COOLING A BATTERY AND AUTOMOBILE COMPRISING A COOLABLE BATTERY SYSTEM

摘要

The invention relates to a battery which comprises at least one integrated first heat exchanger element for dissipating thermal energy from the battery, said element forming at least a portion of the surface of the battery. The integrated first heat exchanger element is an integral part of the battery and is designed as one piece with the battery. The heat exchanger element of the battery can end flush with the surface, but it can also, for example, protrude from the surface or be recessed into the surface of the battery. According to the invention, a coolable battery system is also provided, which has at least one battery described above. The coolable battery system according to the invention further comprises a second heat exchanger element for each battery, wherein said element can be reversibly brought into thermal operative connection with the first heat exchanger element. The invention further relates to a method for cooling a battery according to the invention in a coolable battery system according to the invention, 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, wherein the second heat exchanger element is kept at a lower temperature level than the temperature level of the first heat exchanger element.
