Traction batteries for electric vehicles produced by the Korean company LG Chem have already caused the recall of several thousand Chevrolet, Hyundai and Opel vehicles, and now stationary energy storage systems sold in the United States are being recalled due to the danger of fire.
According to information provided by the manufacturer to Bloomberg, LG Chem became aware of five cases of fire in household electricity storage systems, as a result of which minor damage was caused to property, no one was injured. The newly formed company LG Energy Solution is now investigating the causes of these incidents. Owners of stationary energy storage systems LG Chem of certain models will receive new ones instead of the existing ones; nothing will be required to pay extra for this.
In the United States, electricity storage systems that were recalled were distributed from January 2017 to March 2020. The cells in their batteries must be replaced due to the risk of overheating. Apparently, the same “symptoms” are observed as in traction batteries of electric vehicles. Some cells may overheat and catch fire when they reach 100% charge.
Notably, LG Chem’s electricity storage systems in the United States have already come to the attention of fire safety experts after an incident in Arizona, where one of the batteries exploded and caused harm to several people. Then the South Korean manufacturer refused to admit his guilt.
