The fire problem of new energy vehicles caused by the thermal runaway of lithium-ion batteries has been the pain point of the development of the industry. Thermal runaway has become a bottleneck problem restricting the development of new energy vehicles. In this paper, a thermoelectric coupling abuse model of NCM lithium-ion battery is established, taking into account the internal heat generation and external heat transfer. Using temperature as a coupling factor, a thermal runaway model of thermal abuse of lithium-ion batteries is established. The effects of different parameters on the thermal characteristics of lithium-ion batteries are analyzed, and the thermal runaway characteristics and development rules of lithium-ion batteries under different abuse conditions are revealed.
