The conventional distance estimation system only uses a constant speed and a constant level of road elevation to estimate the driving range of a vehicle. This technique leads to low prediction accuracy. In this project, a new estimation technique namely the Contour Positioning System (CPS) for an electric vehicle is proposed. The CPS provides a more reliable estimation of the electric vehicle battery energy usage by taking into consideration additional factors such as road elevation and regenerative braking energy. In order to perform the CPS calculation, first and foremost, the elevation profile of the selected destination must be determined. In this paper, the automated technique to extract the elevation profile i.e. latitude, longitude and altitude was determined by using Google Maps and Google Earth. This procedure enables the user to obtain accurate road configuration to enable the driver to compute the amount of energy needed to reach the said destination.
