The market for electric vehicles has been expanding considerably in recent years, and with it, the onboard components have technologically evolved. When it comes to new technologies, it is important to pay particular attention to safety, so that the vehicle and, above all, its passengers are protected. One of the main components is the battery, which in addition to determining many important vehicle characteristics such as acceleration, range and price is also one of the most dangerous parts of an electric vehicle because, under certain conditions, it can catch fire or explode. The battery undergoes constant volume changes during use, mainly for two reasons: breathing and swelling.
