Abstract: An apparatus for discharging battery units includes a plurality of carrier units, with respective battery units arranged on top of each; a conveyor system configured to transport individual carrier units; a buffer station configured to receive and temporarily store carrier units; a discharging station configured to receive individual carrier units from the buffer station; a removal station configured to remove individual carrier units from the discharging station; a contacting assembly configured to generate an electrical contact to carrier units accommodated in the discharging station such that a series circuit of battery units is generated, which are arranged on these electrically contacted carrier units to discharge battery units of this series circuit and to disconnect the electrical contact to individual carrier units individually and independently from one another so that the battery units arranged on these carrier units are removed from the series circuit individually and independently from one another

Abstract: A discharge device for discharging a plurality of battery cells having an unknown state-of charge is disclosed. The discharge device includes a contact-connection element for the electrical contact-connection of respective battery cells in the plurality of battery cells, and a short-circuiting element. The contact-connection element includes, for each individual battery cell in the plurality of battery cells, an electrical contact having a non-return device. Each of the non-return devices is configured to prevent any return flow of electricity from the respective battery cells, via the contact-connection element, into a battery cell which is assigned to the respective non-return device such that electricity is removed in a unidirectional manner from the respective battery cell. Respective electrical contacts of the contact-connection element are electrically coupled in the direction of flow of electricity, down-circuit of the respective non-return devices.

Abstract: A tool device, in particular a jigsaw device, includes at least one guide unit for at least partially guiding at least one machine body and/or a workpiece processing motion. The tool device further includes at least one alignment detection unit for detecting an alignment of the guide unit relative to a motor housing and/or relative to a tool receiving unit.
