However, due to the thermal instability of lithium batteries, the probability of fire and explosion under extreme conditions is high. This paper reviews the causes of fire and explosion of lithium-ion batteries from the perspective of physical and chemical mechanism. Conferences > 2018 2nd IEEE Conference on E...
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.
While the flammable, high energy and active material increase their dangers of fire and explosion. The fuel, oxygen and energy can exist in the battery system, which provide the necessary contributions to the combustion triangle, thus there is the possibility of fire and explosion.
Although the probability of an explosion is low, the consequences can be extremely high.
Combustion gases and shell rupture are the requisite conditions for battery explosion. Based on the factors of combustion gases and shell rupture, the integrated fault tree can be built as Fig. 12. According to the fault tree, the minimum cut sets and structural importance degree coefficient of each basic event can be calculated by Boolean algebra.
Failure of the battery may then be accompanied by the release of toxic gas, fire, jet flames, and explosion. This paper is devoted to reviewing the battery fire in battery EVs, hybrid EVs, and electric buses to provide a qualitative understanding of the fire risk and hazards associated with battery powered EVs.
The fuel, oxygen and energy provide the probability of fire and explosion, as the lithium ion battery is a closed system, so the gas products cause the increasing of the inner 378
