Abstract: A switching device for a test stand for electrical components has a support structure and a first contact block attached thereto. The first contact block has first connections for connecting a battery to be tested; one or more second connections for connecting a high-voltage tester; and third connections for connecting a function tester. A second contact block that is a contact bridge and is movable relative to the first contact block is included. The second contact block, in a first contact position, connects first connections to at least one second connection. The first connections are bridged in the first contact position by a bridge element of the first contact block and connected to at least one second connection via the bridge element or, in a first contact position, connects first connections to second connections, wherein the second contact block, in a second contact position, connects first connections to third connections.

Abstract: A battery test stand having a source for providing electrical charging power to a battery to be tested, includes a first connection for connecting a battery first terminal to a source first terminal, and a second connection for connecting, a battery second terminal to a source second terminal, The first connection has a first connector with at least two contact pins. In the mated state, a respective contact pin is seated in each case in an associated contact socket of the first connector and each contact pin forms in each case an electrical contact with each contact socket. The second connection includes a second connector with two contact pins. In the mated state, a respective contact pin is seated in an associated contact socket of the second connector and each contact pin forms an electrical contact with each contact socket, having a monitoring device for monitoring all electrical contacts.

Abstract: A device for testing a battery, having a transport system, wherein the transport system is configured for receiving the battery, for transporting the battery to a test position, and for transporting the battery out of the test position. The device includes an interface, wherein the interface is configured to supply the battery arranged in the test position with electric power; and a fire protection hood, which can be lowered onto the transport system, for shielding the battery from the surroundings.

Abstract: A method for producing a collagenous material in particle form, includes: extracting a collagen- and fat-containing animal raw material using an aqueous extraction solution; optionally separating at least one part of the aqueous phase from the extraction residue; separating the extraction residue into a collagenous solid phase, an aqueous phase, and a fat phase; mixing at least one part of the collagenous solid phase with at least one part of the aqueous phase; at least partly drying the mixed phases; and comminuting the dried phases in order to obtain the collagenous material in particle form.
