Analysis of Traction Battery Damage Value Based on Frontal Impact

As the adoption of new energy vehicles expands globally, the safety performance of their traction batteries has garnered significant attention due to the potential hazards posed by road debris and collisions. These safety concerns have become a major impediment to the advancement of these vehicles. This paper aims to analyze the impact resilience of traction batteries under frontal collision scenarios to evaluate their safety under specific conditions. A multi-level evaluation model for traction batteries is developed and integrated with computer tomography system analysis to investigate the extent of damage sustained by the battery system during frontal impacts. Utilizing a structured battery system damage assessment method, the study provides a quantitative analysis of the damage severity resulting from collisions. This offers both theoretical insights and practical guidance for the testing and evaluation of traction batteries.
