The disclosure describes a battery pack including at least one battery cell, an outer housing that has at least one first housing element, and a cell holder configured to receive the at least one battery cell. In this case the first housing element is constituted by a two-component part that includes at least one first hard component element, one second hard component element and at least one soft component element, the first hard component element and the second hard component element fixedly connected to each other via the at least one soft component element.

Battery pack

A battery pack for a hand-held power tool including a battery pack housing, the battery pack housing accommodating at least two battery cells, and at least one cell connector for connecting the battery cells in parallel and/or in series, the cell connector being connected to a pole of the first battery cell and to a pole of the second battery cell using a welding method, the cell connector including at least two at least partially overlapping, current-carrying cross-sectional areas in an unwelded area between the battery cells.

A battery pack for a hand-held power tool includes at least one interface for establishing a mechanical and/or electrical connection of the battery pack to a hand-held power tool and/or a charging device, the interface having a guide arrangement for attaching the battery pack on the hand-held power tool and/or the charging device along a contacting direction y, and at least four contact elements for electrical contacting of corresponding counter-contact elements on the hand-held power tool and/or corresponding counter-contact elements on the charging device. At least two contact elements are thereby situated offset from one another in the direction of the contacting direction y.

The invention is based on a rechargeable battery charging case, in particular a cordless handheld power tool case, having at least one battery attachment device and a case body. It is proposed that the rechargeable battery charging case has an electrical energy output and a supply unit, which in at least one operating state is connected to the energy output and to the battery attachment device for supplying the energy output.

An electric power tool has an electric drive motor whose speed is adjusted by means of an adjusting device. The adjusting device includes an adjusting element movably supported on the housing of the power tool. The adjusting element is associated with a strain measuring device that produces a measurement signal that is used to adjust the drive motor in response to a movement of the adjusting element.
