e-CNY Vehicle-to-Grid Real-time Settlement System

The lack of a convenient and effective real-time settlement mechanism is the main factor which limits the enthusiasm of users to participate in V2G. To build a real-time measurement, real-time transaction and real-time settlement mechanism, realize the synchronization of fund flow, energy flow, information flow, and improve the participation rate of V2G, a new e-CNY V2G real-time settlement system is constructed in this paper. e-CNY is an electronic currency system that is backed by the “Central Bank of China”. Firstly, the basic characteristics and operation modes of e-CNY are analyzed. Secondly, based on the settlement upon payment and programmable features of e-CNY, a new real-time settlement system is constructed, which composed of V2G pile-side DC energy metering, e-CNY real-time settlement device, and electric vehicle-side e-CNY digital wallet. Finally, the prediction and analysis of the electric vehicles ownership, the charge capacity of electric vehicle and the power consumption per 100 kilometers in Shanghai from 2022 to 2032 are performed. According to the simulation results of the economy for orderly charging and V2G after using e-CNY V2G real-time settlement system, it indicates that the user participation rate significantly promotes the annual internal revenue under different participation rates for orderly charging and V2G modes.
