In this paper, we take advantage of the communication systems which will be adopted for the new vehicle generations in near future and we propose a new electric vehicle (EV) charge/discharge service scheme for large EV density through vehicular ad-hoc networks communications. First, we present a communication protocol for the EV charging/discharging protocol with the uplink and the downlink EV charge /discharge frame format exchanged between EVs and smart grid. Second, we propose our channel access scheme based on a distributed time slot assignment model (DTSA) to allow the EV charging/discharging service negotiations with smart grid before plug-in phase. This DTSA scheme, which is a contention-free channel access mechanism, can improve the EV charging/discharging service access by increasing the successful rate of channel reservation both on control channel (CCH) and service channel (SCH). We propose also three algorithms to manage the EV charge/discharge service reservation and negotiation, respectively, on CCH and SCH. Finally, extensive simulations with NS-2 and MATLAB are conducted to validate the proposed approach and demonstrate the efficiency and effectiveness of the proposed compared to IEEE802.11p and VeMAC while satisfying the defined constraints.
