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.
According to the characteristic of parameters, the sensitivity and severity were taken as two indicators to evaluate the risk and hazard of battery explosion. Moreover, a safety assessment method was proposed based on the two indicators.
The battery pack or system test can involve any of the methods displayed in Figure 2. It is required to test the two directions of the tested object (the vehicle running direction and the horizontal direction perpendicular to the running direction).
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.
4 October 2021 Battery Energy Storage Systems Explosion Hazards moles, or volume at standard conditions such as standard ambient temperature and pressure (SATP), which is gas at 1 bar of pressure and 25°C (77°F).
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.
