Quantitative analysis of influence factors about EV's charging electricity price based on the static non-cooperative game theory

The forthcoming mass popularization and application of electric vehicles (EVs) would prompt the urgent requirement of reasonable charging electricity price. Game theory is used to analyze the interests relationship of the main three players to the EV's development including the government, the charging infrastructure operator and the users. Then, the tripartite game model about the charging electricity price and holdings of EVs is built and gets classical solution on the basis of static non-cooperative game. Focusing on EV's data of nine cities in the Pearl River Delta, the game equilibrium solutions are obtained based on charging infrastructure operator or the government as the leading party respectively. Moreover, the variations of charging electricity price, EVs holdings and the sensitive degree of five influence factors are quantitatively calculated. Ultimately considering the acquired appropriate subsidies of charging infrastructure for the operator offered by government, the accepted game equilibrium solution for both players is produced and the generalized cost of the user is analyzed, which can satisfy the interests of three players. It is beneficial to large-scale proliferation of EVs.
