Sharing Platform Trading Strategy of Private Charging Pile Based on Blockchain

doi:10.12096/j.2096-4528.pgt.21134

Abstract

Abstract:

Aiming at the charging difficulty of electric vehicles and the high idle rate of private charging piles, this paper took electric vehicles and private charging piles as the research objects, and designed the sharing strategy mechanism of private charging piles based on blockchain. To truly reflect the preference degree of electric vehicles to charging piles, the travel route, charging time and user psychology of electric vehicles were modeled, and the comprehensive evaluation index of electric vehicles to charging piles was calculated. The charging trading mechanism of the sharing platform was established to obtain the dynamic electricity price that takes into account the charging pressure in the region. The blockchain and delegated proof of stake consensus mechanisms were used to ensure the security of transactions. The simulation results show that the proposed strategy can provide additional charging options for electric vehicle users to relieve charging pressure and bring certain benefits to the owners of private charging piles. The designed consensus mechanism can effectively prevent false information.

Key words: blockchain, electric vehicle, charging pile, sharing mechanism
