  • Publication number: 20250038285
    Abstract: A battery arrangement with a sensor device for detecting a gas discharge from at least one battery cell of the battery arrangement. The battery cell has a releasable cell degassing opening. The sensor device for detecting the gas discharge has a sensor unit with an electrical line which can be subjected to a test voltage. The sensor unit is arranged in such a way that a gas escaping from the cell degassing opening impinges on the sensor unit, and the electrical line can be damaged by a gas flowing out of the cell degassing opening. In particular, the sensor unit is designed in such a way that the electrical line can be damaged by the outflow pressure of a gas discharging from the cell degassing opening in the event of thermal runaway of the battery cell.

  • Publication number: 20250023130
    Abstract: A battery arrangement with a sensor device for detecting a gas discharge from at least one battery cell, which includes a releasable cell degassing opening. The battery arrangement has a gas discharge channel with at least one gas inlet region, a gas discharge region and at least one flow path from the at least one gas inlet region to the at least one gas discharge region. The sensor device includes at least one sensor element protruding into the flow path with an electrical line which can be damaged by a gas flowing through the gas discharge channel along the at least one flow path and which has escaped from the at least one battery cell.

  • Publication number: 20180241103
    Abstract: An energy storage device comprising at least one storage element with an associated cooling plate, with which the storage element is in thermal contact, as well as at least one channel component, which is fastened on the opposite-lying side of the cooling plate for the formation of at least one cooling channel through which a coolant can flow, wherein the cooling channel is at least as wide as and at least as long as the contact surface between the storage element and the cooling plate, wherein the cooling channel lies opposite the contact surface and covers it completely.
