To fully evaluate the vehicle-to-grid （V2G） response cost of electric vehicles （EVs）, an evaluation model for V2G response cost of EV aggregator is established considering the peak-valley time-of-use tariffs and battery wear. First, considering the co-constraints of energy storage and power output, a refined individual EV model is proposed for V2G response. Then, considering the impact of V2G response on the battery life cycle with different depths of discharge （DOD）, an individual EV battery wear model is developed. Moreover, considering the impact of peak-valley time-of- use tariffs on the charging process of EVs, an evaluation model for the V2G response cost of EV aggregator is developed based on the individual EV battery wear model and from the perspective of EV aggregator operator. At last, case studies are used to validate the effectiveness of the proposed V2G response cost model of EV aggregator, and the impact of peak-valley time-of-use tariffs and battery wear on the V2G response cost is analyzed. The research in this paper provides a basic model for the EV aggregator operator to realize the compensation mechanism for users and participate in the electricity market.
