Development of ITS Information System for EV (Electric Vehicle)

Abstract

In order to achieve a low carbon society, the introduction of EV (electric vehicle) that considers the environment is being promoted. EV has a restriction for the distance which it can drive with one battery charge, and under the present situation there are problems such as too few installation places for battery charge equipment. To promote the introduction of EV, a highly convenient system corresponding to these problems and characteristics is required. This system includes an on-board unit (OBU), a navigation system connected to OBU, a roadside system, and a center system. This system also mounts functions for observing the amount of battery remaining and leading to surrounding battery charge stations while driving, user authentication and a charge settlement, and efficient battery charge management. The experimental system was developed to confirm that the sense of security in the EV and the convenience and the amenity in the battery charge stations will be improved. The effectiveness of the services and practical use of the system were confirmed.
