Because of their lighter weight, higher performance, and rechargeability, lithium-ion batteries are becoming more popular in electric vehicles. Another reason is because it is long-lasting. A lithium ion battery retains 150 watts of energy per kilogramme on average. At the same time, a lead-acid battery may store up to 25 watts of energy per kilogramme. Simply said, compared to other battery types, it has a higher energy density. These batteries can be used to power cars over great distances and to power cell phones for extended periods of time. However, it is this energy density that can cause it to function poorly at times.

'The high energy density of lithium ion batteries can occasionally become unstable and limit the function of cells,' the leading automaker noted on its social media page. As a result, the Battery Management System (BMS) is employed to ensure that the batteries function safely. A PMS is an electronic system that monitors the voltage and current flowing through a battery. It is connected to all of the lithium ion battery's cells. As a result, PMS receives temperature data from various areas of the battery pack.

According to experts, batteries ignite for a variety of reasons. "Fires are caused by production flaws, external damage, and flaws in the usage of PMS," they claim. Experts note out, however, that temperature plays a role in these sorts of batteries as well. "An electric vehicle production representative who did not want to be recognised claimed that while lithium-ion batteries function well in harsh temperatures, they are more prone to catch fire when the outside temperature hits 90 - 100 degrees."
