Abstract:
      Lithium-ion battery has the characteristics of high energy density, high power density, more recycle times, and high voltage, etc., thus it has become more increasingly important in the new energy industry. Its performances, such as cycle efficiency, capacity, power, safety, reliability, and life, are closely related to temperature. Thermal models can be used to simulate the thermal behavior of the battery under application conditions, study the laws of heat generation, heat transfer, and heat dissipation, and calculate its internal and surface temperature changes as well as its temperature field in real time, providing a basis for the design and optimization of the battery and its thermal management system. First, the classification of thermal models and the heat source of lithium-ion battery are introduced. Then, the progress of research on its electrochemistry-thermal coupled model, thermal abuse model, and electro-thermal coupled model is elaborated. Finally, in light of the problems in the thermal models of lithium-ion battery, the developing trend in the future is forecasted.
