An improved route planner-simulator with battery performance considerations for Electric Vehicles

This paper shows the results of a development project that aims to provide Electric Vehicle (EV) drivers the opportunity to know, before making a trip, how the battery will progress during the route. This means drivers will know if they have to stop to recharge the battery and where they should do it, ruling out the idea that makes people reject buying an EV because they can´t make long trips for fear of running out of power supply halfway. This Planner, besides showing the technical data of the route, will display on a road map the selected route from “A to B” with the possibility of one or more intermediate stops to recharge, simulating all the route with a vehicle icon moving along it and a battery image that discharge following the real progress of that vehicle with the conditions of each trip. The data obtained from the Internet, in this case from Google Maps, will be sent to several mathematical algorithms already developed in Matlab. With these data and those obtained from sensors of the car the progress of the State of Charge (SOC) of the battery will be calculated, getting the planner-simulator these data back to display it during the simulation.
