Proposal and evaluation of smart EV charge reservation system

Abstract

In order to realize EV (Electric Vehicle) society, the development of EV charge infrastructuresis indispensable. Under current situation, existing EV charge infrastructures are insufficient. If the numberof EVs continue to increase with this pace, there will be long queues at EV charging stands, and the waitingtime for charging EVs in cities will become much longer. However, if we naively increase capitalinvestment, the low profitability and investment return risk would be a problem as well. In this study, weaim to develop a smart EV charging reservation system that combines a dynamic pricing system accordingto the degree of congestion and a car navigation system that recommends and reserves EV charge standsthat match user's preference (time or price). Using this smart EV charging reservation system, we candisperse their charging locations and decrease total waiting time for charging. We will evaluate the effectof this new system by means of multi-agent simulation.
