Damage Analysis of Traction Battery For New Energy Vehicle Based on Bottom Impact

At present, as the new energy vehicle and traction battery industries enter in a stage of high-quality development, the safety performance of traction batteries has also received widespread attention worldwide. The traction battery system is mainly arranged at the bottom of new energy vehicles, which is easy to cause mechanical damage to the traction battery system, resulting in serious safety hazards for the new energy vehicle. This article studies the battery system of new energy vehicles based on the scenario of bottom impact collision, and discusses the specific damage caused by the bottom impact scenario. Combined with the analysis of the computer tomography system, the damage caused to the traction battery system during the bottom impact process is explored in detail, providing data support for improving the safety protection performance of traction batteries during the bottom impact scenario.
