The disclosure relates to a charging apparatus for a rechargeable battery pack, having a housing, having at least one first rechargeable battery interface that is designed so as to releasably connect the charging apparatus to a first rechargeable battery pack along a first connection direction, having a second rechargeable battery interface that is designed so as to releasably connect the charging apparatus to a second rechargeable battery pack along a second connection direction, wherein the connection directions intersect the rechargeable battery pack in the state connected to the charging apparatus. It is proposed that the first connection direction and the second connection direction are arranged crossing each other.

Charging apparatus for a rechargeable battery pack

A rechargeable battery pack for a hand-held power tool, including a housing having at least first and second housing components, the pack including at least one cell holder, accommodating at least two battery cells in a parallel/series circuit, the battery cells each including two end faces extending perpendicularly to a longitudinal axis; and a pack electronics system including contact elements for establishing electrical connection between the pack and a power tool. The cell holder includes sleeve-like insulating walls, corresponding to the battery cells at least in some areas, to prevent electrical contact between the battery cells. A method for manufacturing a pack for a hand-held power tool, the cell holder including sleeve-like insulating walls, having cylindrical cell openings for accommodating the battery cells, the battery cells being pressed into the cell openings so that a form-locked and force-fit connection is established between the cell holder and the battery cells.

Rechargeable battery pack for a hand-held power tool and method for manufacturing a rechargeable battery pack for a hand-held power tool

A battery pack for a handheld power tool, having a cell holder that accommodates at least one battery cell, the battery cell having a cladding surface that runs parallel to a longitudinal axis, the cladding surface being limited by two end faces that run perpendicular to the longitudinal axis, and the cladding surface and the end faces forming an outer shell of the battery cell, and a battery pack electronics. The battery pack electronics includes at least one circuit board having contact elements for producing an electrical connection between the battery pack and the handheld power tool, in addition at least one contact arrangement corresponding to the battery cell is provided, the contact arrangement electrically contacting the corresponding battery cell at the cladding surface.

A battery charging device includes: at least one power electronics unit supplying a charging voltage; at least one cooling unit cooling the power electronics unit; and an electronics housing accommodating the at least one power electronics unit in at least one of water-tight and dust-tight manner. The electronics housing is cooled from the outside by a fan of the at least one cooling unit during at least one operating mode.

Battery charging device

A battery charging device includes: a battery housing which delimits at least one battery receiving space at least in part; at least one power electronics unit supplying a charging voltage; and an electronics housing which (i) is formed separately from the battery housing, and (ii) accommodates the power electronics unit in at least one of water-protected manner and dust-protected manner.

A tool box, especially a hand tool box, includes a basic box element, that has at least one storage space, which is provided at least for accommodating at least one tool and/or at least one accumulator unit. It is provided that the tool box have at least one light source unit that is at least partially integrated into the basic box element.

Tool box, especially hand tool box

The invention relates to a cooling body of at least one electrical component. According to the invention, a first cooling body section is designed as a spring and a contact surface is provided on the first cooling body section, between the cooling body and the at least one component.

Heat sink of at least one electronic component

An electrical device has an electrical device body, a rechargeable battery pack that can be removed from the electrical device body, and a fastening unit for attaching the rechargeable battery pack to the electrical device body. It is provided that the fastening unit is designed such that electrical contact between the electrical device body and the rechargeable battery pack is established during an attaching motion.
