The invention relates to a battery-powered device, comprising a first controller, a first battery interface, and at least one electric consumer, wherein the first battery interface is configured to receive at least one configurable rechargeable battery pack for supplying energy to the at least one electric consumer; and wherein the first controller is embodied to receive at least one battery charging parameter at the first battery interface, and to reconfigure the at least one battery charging parameter by means of the first battery interface according to the power demands of the at least one electric consumer or according to a given user-specification.

Configurable rechargeable battery pack

The invention relates to a rechargeable battery pack, in particular for a hand-held electrical power tool, comprising: at least two rechargeable battery cells and/or rechargeable battery cell blocks, which are connected in series or in parallel, a housing with a cell carrier for receiving the rechargeable battery cells and/or rechargeable battery cell blocks in rows arranged one above the other, and a printed circuit board, wherein the rechargeable battery cells are connected to the printed circuit board via conductor plates when the rechargeable battery packs are in the installed state, and wherein at least one of the conductor plates at least partially surrounds at least two conductor plate layers when the rechargeable battery pack is in the assembled state with the printed circuit board.

Battery pack and electric hand tool

The invention relates to a configurable rechargeable battery pack, comprising an integrated battery management system and a data interface and a user interface, wherein the battery management system has a data memory for storing at least one rechargeable battery charging parameter and provides, at the data interface, the at least one rechargeable battery charging parameter for an external charging device, and wherein the at least one rechargeable battery charging parameter can be configured by means of an input at the user interface.

The invention relates to a rechargeable battery pack, for use with an electrical hand tool device and which includes at least two series-connected rechargeable battery cells and/or rechargeable battery cell blocks, and an electronics unit having a printed circuit board, and wherein sheet metal conductors for electrically connecting the series-connected rechargeable battery cells and/or rechargeable battery cell blocks are provided, and wherein the sheet metal conductors are connected directly to the printed circuit board.

Rechargeable battery pack and electrical hand tool device

The invention relates to a rechargeable battery pack, in particular for an electrical hand tool device, comprising at least two series-connected rechargeable battery cells () and/or rechargeable batter cell blocks and an electronics unit having a printed circuit board (), wherein sheet metal conductors () for electrically connecting the series-connected rechargeable battery cells () and/or rechargeable battery cell blocks are provided, wherein the sheet metal conductors () are connected directly to the printed circuit board ().

An electrical hand tool device comprises a ventilated housing body, which has inlet and outlet openings for cooling air flow and accommodates the electromotive components of the device, in particular, a motor that is excited by a permanent magnet and is powered by a battery, and a magnet that is provided in the area of the cooling air flow for collecting magnetic or magnetizable dust. In order to protect the electric motor, the device is designed in such a fashion that at least two magnets are provided in the axial direction between the inlet openings and the electromotive components of the device, and a means is provided, which electrically cooperates with the at least two magnets to determine whether a substantial amount of magnetizable dust has collected on the magnets, in which case, a control measure can be performed.

Electrical hand tool with magnets for absorbing dust

The invention relates to a battery pack, especially for a hand-held power tool. Said battery pack comprises a battery housing () and an electronic unit () housed in said battery housing (). The electronic unit () has one or more light sources (). A first light-guiding element () can be inserted into the battery housing () and interacts with the at least one light source () in such a manner that the light emitted by the at least one light source () can be injected into the first light-guiding element ().

Battery pack and hand-held power tool

A switching arrangement for controlling the rpm constancy between idling and full power of universal motors in electric tools has a phase-shift control (IC) which, for setting the set value, is connected at an output via an adjusting resistor with a tap of a voltage divider, and whose trigger output controls an electronic power switch disposed in the electrical circuit of the motor. In order to obtain an optimal readjustment of the load in the entire provided rpm range by means of such a switching arrangement, it is provided that between the tap of the voltage divider and the one output of the phase-control circuit (IC) at least one further adjusting resistor is provided, with which a preferably electronic circuit device is switched in parallel, which is controlled from a point in the voltage divider.
