April 5, 2022, the National Highway Traffic Safety Administration (NHTSA) is launching an investigation into LG Chem to ensure that it's handled other battery recalls appropriately.
NHTSA pointed out in February this year that Stellantis recalled 16741 Pacifica plug-in hybrid vehicles produced from 2017 to 2018, because the car manufacturer said that the hybrid battery pack produced by LG involved 12 vehicle fire reports.
Absolutely, the safety of Lithium batteries is very important for EV and energy storage sysetem (ESS) application area, but many safety accidents happened every year in electric vehicals and home energy storage systems. However, these issues products were uesed NMC lithium batteries in EV and/or ESS. As we konow, the NMC lithium batteris has high electrochemical activities during charge and discharge process,so the accident probablity was very high when the thermal runway was happened on cell during using. so the quality controll is very important and need very high control standard if you use NMC batteries.
Compared with NMC batteries, LifePO4 battery has good safe performance, long cycle life and stability, that had been used in EV,HEV and PHEV like BYD, CATL etc. and also used in home energy storage system (ESS) like powerwall batteries, these batteries had better safe performances in the process of long-term use.
PCENERSYS is a manufacture for Lithium ion battery in ESS (Energy Storage System) application with self developed key technologies including LiFePO₄ cell, BMS (Battery Management System), battery module and system integration. PCENERGY provides different type LifePO4 batteries for ESS and you can vist the website: www.pcenersys.com.
