Some of these batteries have experienced troubling fires and explosions. There have been two types of explosions; flammable gas explosions due to gases generated in battery thermal runaways, and electrical arc explosions leading to structural failure of battery electrical enclosures.
Deflagration pressure and gas burning velocity in one important incident. High-voltage arc induced explosion pressures. Utility-scale lithium-ion energy storage batteries are being installed at an accelerating rate in many parts of the world. Some of these batteries have experienced troubling fires and explosions.
A battery pack for EVs consists of many battery cells that connected series and parallel. When a single cell catches fire or explodes, a “domino effect” will be triggered and propagate through the entire battery pack , posing a huge threat to the vehicle and the personal safety of passengers.
Therefore, the study of battery explosion needs to comprehensively consider the gas and heat production as well as its mechanical impact on the external environment. The goal is to propose effective targeted prevention and control strategies in automotive applications.
In automotive application, an early warning schedule should be built in BMS, and effective protective measures against battery explosion should also be taken, especially under high current charging conditions. 4.
