Research On Recycling Decision Of Power Cell Gradient Utilization Under EPR System

With the increasingly prominent issues of energy security and ecological environment,the development of new energy vehicles has become the only way to alleviate the severe global energy and natural environment.It is an inevitable trend for technology and industrial innovation by automobile manufacturers in various countries.As the core component of new energy vehicles,power battery is the only energy supply device for new energy vehicles.Under the background of the booming new energy vehicles,the power battery industry has also ushered in a new round of opportunities and development.When the power battery can not meet the requirements of the new energy vehicle,a large amount of used power batteries will be generated.Since the waste power battery contains toxic electrolyte and heavy metal elements,it can be discarded at will,not only pollution to the ecological environment but also natural.Resources cause waste.Therefore,in the current domestic implementation of the EPR system,it is of great practical significance to study the gradient utilization of used power batteries.First of all,this paper expounds the research background and research significance of the gradient utilization of power battery,and sorts out the related theories and methods of power battery recycling,and combines the use of power battery with the requirements of recycling and recycling of waste products at home and abroad.Power batteries are classified.The first type of used power battery refers to a power battery that can be directly used twice;the second type of used power battery refers to a power battery that can recover precious metals.In this paper,different types of used power batteries are treated differently to extend the life cycle of the power battery,and the gradient utilization of the used power battery under the EPR system is realized.Secondly,in order to explore the impact of the recycling cost and subsidy price on the supply chain under the recovery mode of the power battery vendor,the supply chain modeling theory was used to create a battery manufacturer,a seller,a consumer,a power plant and a precious metal recycling station.The closed-loop supply chain centralized and decentralized decision-making model uses game theory to discuss the impact of subsidized prices and recycling costs controlled by battery manufacturers and vendors on the closed-loop supply chain,while at the same time providing supplythrough appropriate profit sharing mechanisms.Chain coordination.The study found that the increase in recycling costs under centralized decision-making will result in higher sales prices and lower recovery rates.Under decentralized decision-making,the increase in subsidy prices will lead to lower sales prices and higher recovery rates.Finally,based on the research of the front part of the battery gradient utilization,the sales target of the first type of power battery is adjusted to a competitive power plant market.Here,the relevant theory is used to establish the gradient pricing model of the gradient utilization chain of the power battery.On the basis of this,the game theory theory is used to study the optimal differential pricing under the conditions of centralized decision-making and decentralized decision-making in the closed-loop supply chain,and the optimal pricing strategy and optimal profit under different decision conditions are obtained.And introduce a revenue sharing contract to coordinate the supply chain under decentralized decision conditions.The study finally verified the accuracy of the proposition and inference through a case study.
