Research on New Energy Vehicle Battery (NEV) Recycling Model Considering Carbon Emission

This paper focuses on the carbon emission problem of new energy vehicle (NEV) battery recycling, constructs a tripartite evolutionary game model of battery manufactures, new energy vehicle original equipment manufacturers (NEV OEMs) and certified recyclers, analyzes the stability of each party’s strategy selection and the relationship between the influence of the elements, and simulates to verify the validity of the conclusions, and arrives at the conditions for the occurrence of the lowest carbon emission stabilizing strategy combinations, and puts forward countermeasure suggestions accordingly, and analyzes the effects of the changes of the key parameters on the equilibrium results, and the study shows that (1) Carbon emission cost, battery decomposition cost, recycling channel construction cost and R&D cost are the main factors affecting the equilibrium results. (2) Under the carbon emission reduction policy, the battery manufacturer’s investment in low-carbon production can help other actors in the supply chain to reduce the negative impact of the policy so that they can reduce their costs. (3) The cooperative recycling model based on the recycling network constructed by vehicle manufacturers can maximize the interests of all parties in the supply chain. The findings of the study provide management insights for governments, battery manufacturers, NEV OEMs, and certified recyclers.
