Explosionsfall einer Container-Energiespeicherbatterie
In der Regel kommt es infolge einer unsachgemäßen Nutzung oder eines mechanischen Defekts zu einem Temperaturanstieg. Bei dieser Erhitzung einer Akkuzelle wird dann der Siedepunkt des Elektrolyts erreicht, dieser verdampft. Damit wird die gesamte Zelle unter einen hohen Druck gesetzt und bläht sich auf (was auch zur Explosion führen kann, s
Why are batteries prone to fires & explosions?
Some of these batteries have experienced troubling fires and explosions. There have been two types of explosions; flammable gas explosions due to gases generated in battery thermal runaways, and electrical arc explosions leading to structural failure of battery electrical enclosures.
What causes a battery enclosure to explode?
The large explosion incidents, in which battery system enclosures are damaged, are due to the deflagration of accumulated flammable gases generated during cell thermal runaways within one or more modules. Smaller explosions are often due to energetic arc flashes within modules or rack electrical protection enclosures.
Why are lithium-ion batteries causing fires and explosions?
Deflagration pressure and gas burning velocity in one important incident. High-voltage arc induced explosion pressures. Utility-scale lithium-ion energy storage batteries are being installed at an accelerating rate in many parts of the world. Some of these batteries have experienced troubling fires and explosions.
What causes large-scale lithium-ion energy storage battery fires?
Several large-scale lithium-ion energy storage battery fire incidents have involved explosions. The large explosion incidents, in which battery system enclosures are damaged, are due to the deflagration of accumulated flammable gases generated during cell thermal runaways within one or more modules.
What caused the battery container fire in Thuringia?
The cause of the battery container fire in Thuringia, Germany, is still unclear. The damage caused is enormous. From pv magazine ESS News site Batteries in an overseas container caught fire on June 7 at Suncycle’s engineering and test center in Thuringia, Germany.
Why are batteries exploding in South Korea?
Other fires in South Korea and elsewhere have involved explosions from other causes, including a vulnerability of some batteries to operate at abnormally high temperatures under certain fault conditions (Yonhap News Agency, 2020).
