A battery pack includes a means configured to, when an abnormal phenomenon, such as fire outbreak or heat generation, occurs in a battery cell, prevent fire or heat from propagating to another battery cell adjacent thereto. The battery pack includes a plurality of battery cells, a case configured to receive the plurality of battery cells, an energy discharging means configured to discharge energy of the battery pack when the abnormal phenomenon occurs, and a fire extinguishing means configured to discharge aerosol at an operating temperature or higher in order to extinguish flames generated in the battery pack.

A battery arrangement with a battery housing in which at least one battery element is arranged. The battery arrangement includes an extinguishing device which has at least one extinguishing unit which is also arranged in the battery housing. The extinguishing unit includes a housing element and an extinguishing agent which is arranged in a cavity in the housing element. The extinguishing unit has a detonation mechanism which is designed to cause a detonation of the housing element and a release of the extinguishing agent in the form of an aerosol when a predetermined fire condition, which results from a fire in the at least one battery element, is present.

A field of enclosures for electronics and electrical components within electric devices, such as electric drive devices for industrial applications, e.g. for working machine and marine applications, and more particularly to an electronics enclosure arrangement for an electric device, and to an electric device. The electronics enclosure arrangement according to the present invention is arranged for an electric device, the electric device including one or more circuit boards and electronics components assembled on the one or more circuit boards, wherein the electronics enclosure arrangement includes an electronics enclosure cover; and an at least one volume element part, arranged in the space between the electronics enclosure cover and the one or more circuit boards with the electronics components.

A battery pack has a fire-extinguishing unit including a fire-extinguishing material, and more particularly to a battery module having a fire-extinguishing unit including a fire-extinguishing material, the battery module including a plurality of battery cells stacked in a vertical direction or a horizontal direction and a fire-extinguishing unit located adjacent to each of the battery cells, wherein the fire-extinguishing unit includes a fire-extinguishing pack containing a fire-extinguishing material and at least one breaking unit interposed between the battery cell and the fire-extinguishing pack.

A fire suppression system that includes a non-rigid pouch, a quantity of suppressant, a quantity of gas, and a pressurized gas source. The non-rigid pouch that includes an exterior surface and an interior space. The quantity of suppressant, the quantity of gas, and the pressurized gas source is contained within said interior space. The pressurize gas source is configured to increase the internal pressure of the non-rigid pouch by injecting gas into the interior space. The non-rigid pouch is configured to rupture when the internal pressure exceeds a predetermined threshold pressure.

A firefighting system includes a controller, a battery, and a firefighting device connected to the battery. When a temperature of the battery reaches a temperature threshold indicating that the battery is on fire, the firefighting device releases an extinguishing agent to the battery to extinguish the fire. The controller is configured to obtain a pressure value in the firefighting device. When the pressure value in the firefighting device meets a preset condition, the controller generates warning information indicating that the firefighting device or the battery is faulty.
