Energy Consumption Estimation in Electric Vehicles Considering Driving Style

The limitation on the range of electric vehicles makes quite important to use an accurate energy consumption estimation tool. In general, estimations are based solely on the total distance, although it is known that the characteristics of the route and driving style influence significantly on energy consumption. In this paper, a tool that estimates the energy consumption of an electric vehicle in a city route taking into account such variables is shown, but without needing a deterministic knowledge of the characteristics of the vehicle or driving cycles. To do this, a neural network that takes as input data driving style and route variables is used. The validation results have been quite satisfactory to increase reliability in predicting consumption of the vehicle and enhance user confidence in the capabilities of electric vehicles.
