Recently, in the field of mobility, car sharing services are expanding. Attention is also paid on increasing use of electric vehicles (EVs). In the field of energy, studies are being conducted on energy management using EVs. However, most of these are targeted at private cars and commercial cars, in which actual usage is fixed to some extent.
In this article, we focus on car sharing of EVs, which are difficult to know when they will be used and which are difficult to restrict the use of vehicles. Then, we aim to design a car sharing system and an energy management system with charge / discharge using EVs. In particular, this article describes the development of a preference model for car sharing vehicles and the operation results of the designed energy management system. As a result, it was found that users select a car, taking the volume of the car, the usage fee, and the type of car into consideration. By introducing model predictive control into the energy management system, energy cost could be substantially reduced, while SOC can be maintained at a high level, making it easier to respond to sudden reservations. It was shown that there is a possibility of further profit by increasing the charge / discharge speed.
