The invention relates to a motor vehicle battery, comprising a battery module which comprises a plurality of battery cells arranged in the manner of a stack, a support structure surrounding the battery module, comprising two side parts parallel to the side walls of such a stack of battery cells and, arranged between the heat sink and a lower side of the battery module, which thermally couples the battery module to the heat sink. In order to improve the heat dissipation of the motor vehicle battery, a thermally conductive element is arranged in at least one of the intermediate regions between two adjacent battery cells and extends from the intermediate region to at least one of the side parts of the support structure Is contacted. The side part, to which the thermally conductive element is thermally contacted, is also thermally coupled to the heat sink.

    本发明涉及一种机动车电池,包括电池模块,具有多个堆垛状布置的电池单池;包围电池模块的保持结构,保持结构具有两个侧面部件,所述侧面部件平行于由电池单池构成的这种堆垛的侧面壁并且在电池模块的对置的侧面壁处布置;布置在电池模块下方的冷却体;布置在冷却体和电池模块的下侧面之间的第一热量传导垫,所述第一热量传导垫将所述电池模块与所述冷却体热耦合。为了改善机动车电池的热量导出,在构造在两个相邻的电池单池之间的中间区域中的至少一个中布置有能够传导热量的元件,其从所述中间区域延伸出来直至所述保持结构的侧面部件中的至少一个处并且在其处热接触。能够传导热量的元件在其处热接触的侧面部件此外与所述冷却体热耦合。
