Abstract:

In recent years, the thermal runaway problem of lithium-ion battery has become the main bottleneck restraining the development of power battery of new energy vehicles. In this paper, a comprehensive review of the research on the thermal runaway problem of the power battery of new energy vehicles is carried out, with the inducment of the thermal runaway of lithium-ion battery expounded and the thermal runaway process of lithium-ion battery and the characteristics of the thermal runaway of lithium-ion battery under different variable conditions introduced. Based on the characteristic parameters of thermal runaway of lithium-ion battery, the early warning methods and fire suppression methods applicable to lithium-ion battery fire are reviewed, and the shortcomings and development trend of the current research on thermal runaway of power battery of new energy vehicles are summarized, providing certain reference for the development of power battery of new energy vehicles.

Key words: power battery, thermal runaway, fire warning, fire suppression
