Research Status and Analysis for Battery Safety Accidents in Electric Vehicles

Abstract: :Battery safety has seriously affected the popularity and promotion of electric vehicles. In recent years, battery fire incidents of electric vehicles have occurred frequently, arousing great social concern. The main safety accidents of electric vehicles in the past five years are analyzed in this papery. The distribution and development of the causes of the electric vehicle fire events over the years are summarized. The characteristics of battery failures behind the major accident causes and their mechanism o… Show more

“…However, the safety of lithium-ion batteries is the stumbling block that restricts their large-scale application. The safety problem is mainly manifested in the fire caused by the thermal runaway because of overcharging, short circuits, and impacts, which is a great challenge for the development of lithium-ion batteries. Methods to improve the safety of lithium-ion batteries include the modification of electrolyte, surface treatment of separators, , modification of the cathode, development of battery management systems, and application of flame retardants.…”

“…There are three types of battery short circuits from the perspective of a trigger mechanism; namely, a battery short circuit caused by overcharge/discharge, a battery short circuit caused by mechanical damage, and a self-induced battery short circuit. Compared with the other two types of battery short circuits, the self-induced battery short circuit features strong latency and long action duration [47].…”
