A battery with a fire protection device, wherein the battery includes a plurality of battery cells and a battery housing, wherein a respective battery cell is arranged in an interior space of the battery housing. The fire protection device includes a composite layer with a thermal insulation layer and with a protective layer arranged on the insulation layer, wherein the composite layer is arranged on a battery housing interior side facing the interior space of the battery housing, and the insulation layer is arranged as an intermediate layer between a surface of the battery housing interior side and the protective layer and is protected by the protective layer against a gas and/or flame stream exiting the respective battery cell in the event of damage, whereby its thermally insulating properties are maintained.

Battery with a fire protection device and motor vehicle

A high-voltage battery for an electrically operated vehicle, the battery housing of which has a housing cover and a housing lower part which delimit a housing interior which is divided into at least one battery cell compartment equipped with battery cells and at least one component compartment for electronic components. A degassing space is formed between a battery cell top of the battery cells and the housing cover, into which space hot exhaust gas flows during a thermal event in one of the battery cells from an exhaust gas outlet of the damaged battery cell. The high-voltage battery has a partition wall which separates the degassing space from the component compartment.

High-voltage battery for an electrically operated vehicle

A motor vehicle having a vehicle body an electrical traction machine, and at least one electrical energy accumulator designed as a traction battery for temporarily storing electrical energy for operating the traction machine. The vehicle body and/or a battery housing of the traction battery is/are provided at least in some regions within intumescent fire protection coating.

Motor vehicle

A cover for a battery housing of a high-voltage vehicle battery. The cover includes a composite material which for its part comprises a polymer matrix and an at least fire retardant material embedded in said polymer matrix. In addition, the cover includes an electrically conductive layer which forms an electromagnetic shield.

Cover for a battery housing of a high-voltage vehicle battery and battery housing

A plug connection for coupling a first and a second electrical connection of a first high-voltage component to a first and a second electric connection of a second high-voltage component, wherein the plug connection is provided with a housing in which is arranged as a first pair of high-volt terminals for coupling to the first and the second electric connection of the high-voltage component as well as a second pair of high-voltage terminals for coupling to the first and to the second electric connection of the second high-voltage component, wherein at least the first and the second high-voltage terminal are mounted so that they are movable relative to the second pair of connections of the plug connection in the housing.
