Abstract

A method for producing a mechanical and thermal system for a modular battery. The system has a module, which involves a module housing of the module being connected, on a thermally conductive module side, to a cooling apparatus. The module includes an energy storage unit and a power electronics unit, arranged on a circuit board, which are thermally isolated from each other by a first and a second thermally conductive element, which dissipates heat to the module side thermally connected to the cooling apparatus, and are integrated in the module housing, by virtue of the energy storage unit being connected to the first thermally conductive element, which contacts the module side connected to the cooling apparatus, and by virtue of the circuit board and the energy storage unit having the second thermally conductive element arranged between them, which second thermally conductive element contacts the module side connected to the cooling apparatus.
