Abstract

Method for providing cooling of a power electronics system which is integrated in a battery module, in which method the battery module has a battery housing, containing a large number of energy storage units and the power electronics system which is integrated adjacent thereto and includes a printed circuit board which is populated with power semiconductor switches, and a thermally conductive element which creates thermal contact between the respective energy storage units and the power electronics system. Cooling of the power electronics system is achieved by the thermally conductive element which renders possible transfer of thermal energy from the power electronics system to the energy storage units. At least one side of the battery housing is coupled to a cooling system. A surface area of the thermally conductive element is connected to a respective energy storage unit and is contacted by way of a respective curved portion.
