Abstract: A battery pack is disclosed that includes a housing, including a cell holder, including at least one battery cell, the battery cell being at least partially received in the cell holder, including a cell connector, the cell connector being designed for electrical connection of the battery cell, and including a printed circuit board, the cell connector being electrically connected to the printed circuit board. The battery pack also has a mounting element to support the connection of the cell connector to the printed circuit board, the mounting element being located in a cut-out of the printed circuit board.

Abstract: 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.

Abstract: A rechargeable battery pack, in particular to an electrical contact apparatus for a rechargeable battery pack. The electrical contact apparatus includes a cell connector by way of which the electrical contact apparatus is electrically connectable to a battery cell, an electrical contact by way of which the electrical contact apparatus is connectable to a load and/or to a charging apparatus, and a flat connector for electrical and mechanical connection of the cell connector to the electrical contact. The cell connector is intermaterially connected in a first connecting region to the flat connector, and the flat connector is intermaterially connected in a second connecting region to the electrical contact. At least one intermaterial connection is effected using a welding process.

Abstract: 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.

Abstract: 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.

Abstract: The present invention relates to a method, with which an electric power tool is operated, which comprises a drive motor, a drive unit as well as a tool, the tool being operated by means of the drive unit and the drive motor. Said tool can be operated in at least two operating modes, said operating modes varying due to the properties of the drive motor and/or the drive unit. The setting of at least one of the two operating modes occurs automatically. The present invention furthermore relates to an electric power tool, which particularly can be operated with the one method according to the invention, having a drive motor, a drive unit as well as a tool, said tool being operable in at least two operating modes by means of the drive unit and the drive motor. The operating modes vary due to the properties of the drive motor and/or the drive unit.
