After fires reported in Kona electric cars, in South Korea, the Hyundai commented on the problem. According to the Asian automaker, one of the anodes present in the cells of the LG Energy Solution (LGES) batteries caused the fire.
In an interview with the website InsideEVs, Hyundai explained that investigations by the South Korean Ministry of Land, Infrastructure and Transport pointed out that the folded anode plate "could allow the lithium plate on the anode plate to touch the cathode, resulting in an electrical short". More than 15 fires have been recorded.
The electrical short is when there is a passage of very high electric current and, in the materials used, causes a temperature rise, which can catch fire, as happened in Kona cars. All defective cells were from LGES manufactured in Nanjing.
In February of this year, Hyundai recalled of all batteries in the Kona vehicle fleet in the country. The electric car had 77 thousand copies sold, an investment of US $ 540 million.
LG Chem, which makes the batteries, denied the cause of the fire. The company also said that the problem did not appear when reproduced in tests. In addition to Hyundai vehicles, General Motors' Chevy Bolt faced problems with similar battery cells in the United States. The brand, however, preferred to handle the situation more discreetly.
Hyundai confirmed that the electric model Ioniq 5 will have batteries from SK Innovation. The brand, however, faces problems in the United States. The company is under investigation by the International Trade Commission on charges of stealing secrets from LG Chem.
US President Joe Biden will review her ban for 150 years. Thus, the SK Innovation plant in the state of Georgia depends on his decision. If closed, two models of commercial vehicles may be affected. They are Ford's electric F-4 and Volkswagen's ID.XNUMX.
