Abstract: The rapidly increasing energy density of lithium-ion power battery solves the “range anxiety” of electric vehicles effectively, meanwhile, it puts forward more stringent requirements on the heat dissipation capacity of battery thermal management system. The thermal management system with liquid cooling plate at the bottom of the battery pack has been widely used by various automobile manufacturers due to its advantages in higher heat dissipation, reliability, longer life and lower cost. However, the uneven distribution of battery surface temperature makes it difficult to improve the cooling performance of liquid cooling plate. The phase change thermal control device is the key to realize the efficient thermal management of power battery due to its excellent heat transfer performance. As a result, composite thermal control technology, consisted by phase change thermal control device and liquid cooling plate, has become an important development direction and hot spot in the field of efficient heat dissipation of power battery. This review introduces the principle and process of thermal runaway of lithium-ion power battery, summarizing the progress and pointing out the existing problems of heat dissipation technology of power battery, and analyses and outline the technical characteristics of phase change thermal control device of power battery. Furthermore, and scientific prediction and prospect are suggested.
