At present, environmental pollution and energy shortage are becoming increasingly serious, and the automobile industry is also moving in the direction of energy conservation and environmental protection. In order to promote the research on the power performance and fuel economy of hybrid electric vehicles, this paper briefly analyzes the working principle of the lithium-ion battery and the factors affecting the life of the lithium-ion battery, summarizes the research status of different methods for predicting the remaining life of the lithium-ion battery and analyzes their advantages and disadvantages. According to the working mode of hybrid electric vehicles, the working mechanism of energy control management strategies are briefly explained, and the development status of energy control management strategies based on rules, optimization and artificial intelligence is described respectively. The influence of battery life control management strategy on vehicle economic performance is discussed. According to the relevant literature analysis, it is found that the battery life prediction method combining multiple methods is more superior, and the energy control management strategy considering battery life has a better effect on improving the fuel economy of hybrid electric vehicles. The problems of battery life prediction and energy control management strategies for hybrid electric vehicles are summarized and the future development direction is forecasted.
