Safety research on the power Li-ion battery cells for electric vehicles

Electric vehicles (EVs) are considered as an effective measure to significantly reduce greenhouse gas emission associated with the usage of fossil fuels. The dominant energy storage systems for EVs currently is lithium-ion (Li-ion) batteries due to their advantages over other types of batteries. EVs safety are mainly determined by battery safety, which has attracted much public attention in recent years. This thesis focuses on studying the safety performance of Li-ion batteries under mechanical abusive conditions such as EV crashes. With the efforts of this thesis, the safety performance of EVs under crash accidents can be improved, which will benefit the development and wide adoption of EVs.
