Abstract:

With the advance of manufacturing and new energy technology, new energy vehicles are trusted by consumers for their energy-saving and environmental protection characteristics. Due to policy and technological support, the global sales of new energy vehicles are gradually increasing.Although new energy vehicles have many advantages for consumers and the environment, the rapidly increasing number of new energy vehicles and their core component, power batteries, have also brought many challenges. At present, the lifespan of the first batch of new energy vehicles is approaching its end. A large number of scrapped new energy vehicles and retired power batteries not only cause waste of resources, but also pose certain environmental hazards. However, the large-scale waste disposal also contains huge business opportunities. On the one hand, although new energy vehicles have reached the end of their lifespan, some components still have high reuse value, such as motors, high-voltage wiring harnesses, and transmissions. On the other hand, retired power batteries still have a capacity of 70% to 80%, and cascading utilization can still play an important value.To promote the effective recycling of end-of-life new energy vehicles, thereby promoting the remanufacturing of key components and the echelon utilization of power batteries, the optimal cost-sharing mechanism for a closed-loop supply chain (CLSC) of new energy vehicles is explored based on extended producer responsibility (EPR). The decision-making CLSC model, composed of a battery supplier, an automobile manufacturer and a collector, is established, and then the scenarios of no cost sharing, the supplier sharing cost and the manufacturer sharing cost are investigated. Subsequently, the economic, environmental and social benefits of the CLSC are studied. The results show that, with the increase of cost-sharing proportion, the selling price of unit vehicle, the recovery rate of end-of-life vehicles, consumer surplus, the profits of the manufacturer and the CLSC, the environmental benefits and the social welfare remain unchanged if the supplier shares collection cost, under which, the cost-sharing mechanism only changes the profit distribution between the supplier and the collector; under the scenario of the battery supplier sharing collection cost, the collector’s profit decreases with the cost-sharing proportion; from the perspectives of the CLSC’s profits, consumers, the environment and social welfare, the manufacturer is ought to share collect cost rather than the supplier.
