Abstract:
This paper presents a method to provide route assistance for electric vehicles by forecasting availability of charging spots in a charging station. The method uses location and reachability information of other electric vehicles along the route in order to estimate charging spot occupancy ratio at the charging station. By using such information, a risk factor for charging at a station along a planned route of an electric vehicle is calculated. The risk factor is continuously monitored, and when risk becomes high, a new route based on other charging stations located along the route is proposed to the driver. By dynamically monitoring travel routes based on charging station capacity and population of electric vehicles around the charging station, a prediction can be made about the availability of charging stations. Thus, in order to have faster travel times, electric vehicle drivers can be opportunistically advised to take appropriate routes with less crowded charging stations.
