Research on New Energy Vehicle Power Battery Recycling Deposit System Based on Evolutionary Game Perspective

Abstract

With the booming development of the new energy vehicle (NEV) industry, the issue of power battery recycling has increasingly attracted attention. Standardized recycling of power batteries can reduce environmental pollution and promote sustainable resource utilization. This paper employs evolutionary game theory to construct two models of deposit systems for the recycling of new energy vehicle power batteries: one under market mechanisms and the other with government participation. The evolutionary stable strategies among vehicle manufacturers, consumers, and the government are examined, and the stable equilibrium points of the models are analyzed. Finally, Matlab is used to conduct a simulation analysis of the deposit system with government participation. The results indicate that the deposit system under market mechanisms is difficult to constrain consumer behavior, while the deposit system with government participation is conducive to promoting the achievement of long-term environmental protection goals. These findings provide valuable insights for policymakers in designing deposit–refund systems and contribute to advancing the sustainable development of the NEV industry.
