Failure Consequence Analysis of E-Vehicle Batteries
Research Project

The process of developing more effective, safer and environmentally friendly E-Vehicles, as well as well functioning systems for battery reuse and recycling, demands for comprehensive understanding of potential consequences of a critical battery failure. Although being very rare, a critical battery failure occurring in an E-Vehicle using Li-ion technology, can result in a rapid temperature increase inside the battery. As a consequence, it will ventilate its interior gases, and at worst, fire and/or explosion may occur. This project will investigate the relationship between the pre-failure conditions of a commercial vehicle battery, and the post-failure consequences of such an event. A test matrix of batteries with different SOC will be exposed to a range of temperature increase rates as well as inert and air containing atmosphere. After such abuse tests, a post mortem study will be conducted on a selection of cells. The results will contribute to a safer post crash and failure handling.
