Cost-Benefit Calculation And Analysis Of V2g System

In the new electricity tariff market, as an important part of the smart grid, V2G (vehicle-to-grid) has been obtained widespread concern and in-depth study. In this paper, taking the scenario of year 2020 in the urban district of Chongqing, China for example, the size of EVs (electric vehicles) and EV charging facilities arc estimated, and V2G system's net revenue are calculated. The results show that earnings per V2G electric car is still too small, and it's not enough to stimulate electric car owners to participate in V2G mode. The main reason is that the high cost per kWh of EV battery and relatively small peak-valley electricity price ratio.
