Online Seminar on LS-DYNA Battery Thermal Runaway Testing and Simulation

In recent years, with the popularization and explosive growth of electric vehicles in China, batteries for electric vehicles often encounter mechanical, electrical, and thermal abuse, leading to thermal runaway of the battery and frequent fire accidents, which seriously affect people's lives and property safety. For all battery and electric vehicle manufacturers, it is necessary to discover and understand the mechanism of battery thermal runaway through experiments or simulations, so as to find corresponding engineering application solutions.

Based on the above issues, Shanghai Zhuowei Information Technology Co., Ltd., in collaboration with Austria's 4a engineering, will host an online seminar on LS-DYNA battery thermal runaway testing and simulation technology on June 6, 2023. The seminar will focus on introducing the relevant tests conducted by 4a engineering in battery thermal runaway and the results of LS-DYNA simulation analysis, providing customers with relevant ideas and methods. The topics of this seminar are as follows:
