Abstract

A battery module having at least one battery cell is disclosed, in particular a lithium-ion battery cell, comprising a housing, in which the at least one battery cell is accommodated, and a temperature-regulating element, wherein a Peltier element is furthermore arranged between the at least one battery cell and the temperature-regulating element, which Peltier element is thermally conductively connected in each case to the at least one battery cell and the temperature-regulating element, and which Peltier element is furthermore connected to a voltage source in such a way that heat transfer between the at least one battery cell and the temperature-regulating element is able to be formed by means of the Peltier element, wherein a compensation element for homogenizing the temperature, said compensation element being formed from a metallic material, is furthermore arranged between the at least one battery cell and the Peltier element, wherein preferably the at least one battery cell is directly or cohesively connected to the compensation element.
