Impact of Fast Charging on Lithium-ion Battery in Electric Vehicle Application

摘要

This paper presents the impact of fast charging on Lithium-ion batteries in electric vehicles (EVs) application. This impact occurred the charging accident based on chemical gas components of the Lithium-ion battery. According to the lithium-ion battery is popular used to be the primary energy for electric driving destination target and defined in high volume per energy density. The scheme of the charging station is used to find the gas volume of the lithium-ion battery component from the EVs. ALOHA software was applied to analyze the charging accident. The gas releases from the lithium-ion battery were selected to analyze the impact on the surrounding area and the environment of the fast charging station. The fast charging units are divided into 3 scenarios with 1, 5 or 10 EVs for the charging process. The simulation results for the Carbon monoxide (CO) showed the most impact to the thermal radiation treat zone, the flammable treat zone of 10 m and 54 m. Meanwhile, the toxic treat zone from the smoke generation showed the large scale of the free space area and concerned the wind flow direction. Therefore, the impact from the EVs during charging accidents needs to be studied to provide vital information for emergency situations and to advise on the preparation of optimal conditions for EV users and participants.
