  • Publication number: 20240088454
    Abstract: A method for producing an electrical energy store is provided, including providing a housing, at least one positive electrode, which includes a first active material, and at least one negative electrode, which includes a second active material, which are inserted into the housing. Then, a gas mixture is metered into an empty volume of the housing, and the housing is sealed in a gas-tight manner. The gas mixture includes at least one gas component which is at least partially reacted with at least one of the first active material and the second active material after the housing has been sealed. An electrical energy store is also provided.

  • Patent number: 11387599
    Abstract: The invention relates to an apparatus for connecting a power cable to an electronic unit of a power tool having at least one clamp for clamping a connecting line of the power cable and a contact element for establishing an electrical contact between the connecting line and the electronic unit. The clamp and the contact element are arranged on a connecting element extending through an opening in a housing element, which spatially separates the clamp from the electronic unit. The opening is sealed by a seal bearing against the connecting element.

  • Patent number: 10381903
    Abstract: The present invention relates to a method for producing a stator which includes the steps of inserting a stator segment into a former; introducing a coil wire winding into a coil space of the stator segment, and out via a slot which is located in the region between two pole horns; cohesively connecting the turns of the coil at least partially, at least in parts of that region of the coil, which is located outside the slot; and removing the former.

  • Patent number: 9597624
    Abstract: In a preferred embodiment, an angle grinder has a housing containing its electromotive drive, the housing having a free end from which an electric power cable extends, the free end having air intake openings via which cooling air is drawn into the housing. A filter assembly has a body and a filter medium supported by the body, the body being detachably attachable to the free end of the housing via, in some embodiments, latching projections. The body and the filter medium together form a projection-free outer face of the angle grinder when the filter assembly is attached to the free end of the housing. Air drawn into the air intake openings enters the filter assembly by way of the projection-free outer face and passes through the filter medium prior to being drawn into the air intake openings. The filter assembly may include a slotted opening through which the power cable extends.
