Abstract (en)
[origin: WO2022017853A1] The invention relates to a battery pack for an electric hand-held power tool, wherein the battery pack has a housing with at least one pouch cell arranged therein, and a deformable pressure equalization element is arranged parallel to the pouch cell such that the pressure equalization element can give way to a volume increase of the pouch cell. The pressure equalization element is profiled such that a convection current can pass along the pouch cell despite the volume increase of the pouch cell.
