With the increasing global energy and environmental problems, the disadvantages of traditional energy are becoming increasingly apparent. As a clean emerging energy, electric energy can not only alleviate the shortage of traditional energy, but also improve environmental problems. Therefore, the development of electric vehicle industry is inevitable. However, with the expansion of the scale of electric vehicles, their charging and discharging behavior will have an impact on the operation of the power grid, so it is necessary to optimize the charging efficiency(CE) of new energy vehicles(NEV). Based on the principle and technology of energy storage, this paper studies the optimization of battery CE of NEV; This paper briefly introduces the structure of new energy vehicle, puts forward the principle and technology of energy storage, and discusses the basic structure and working principle of lithium battery of new energy vehicle and the model of power battery; Finally, based on the principle and technology of energy storage, the CE of new energy vehicle battery is optimized. Through the design of optimization control strategy for CE of new energy vehicle and the comparison of charging schemes in the dc/dc circuit system modeling, analysis and test system, the effectiveness of the scheme to improve CE in this paper is verified.
