Abstract

In the year 2020, the cumulative production and sales of new energy vehicles in China have reached 1.366, and 1.367 million units, which have increased by 7.5% and 10.9% over the previous year. To solve the problem of used batteries, the power battery echelon use system has been proposed. This paper constructs a three-party game supply chain model for one battery manufacturer, one car manufacturer, and one third-party recycler to analyze the impact of the external environment on the supply chain and to a new coordination contract. The research results show that: the retail price of the high-capacity used battery always changes in the same direction as the retail price of the low-capacity used battery. The profit of the battery manufacturer and third-party recycler in the decentralized decision-making model is affected by the retail price of the low-capacity used battery, but the car manufacturers are not affected by it. With the increase in the retail price of the low-capacity used battery, the profits of the third-party recycler will be greater than that of the car manufacturer. The use of profit transfer contracts and the cost-sharing contract can coordinate the supply chain and increase the demand for automobiles and the actual recycling volume. Interestingly, for the third-party recycler, the smaller the cost-shared, the more additional benefits it will get. The actual recycling volume is mainly affected by the market environment.
