Desarrollo de una metodología para determinar la autonomía de un vehículo eléctrico mediante ciclos reales de conducción

Abstract

This research determines the genuine autonomy of an SUV-type electric vehicle in Ambato City. An experimental analysis was carried out through representative driving cycles to outline the vehicle's actual scope. Therefore, the project aim is to determine the autonomy using a statistical estimate of urban routes in Ambato city. This research was developed based on the three urban routes established through several significant factors such as geographical location, climatic conditions, permitted speed limits, slopes, and other tools. A global positioning device (GPS) was used such as VBOX GPS and ELM OBDII, allowing data to be obtained in real-time, once the roads were determined and the vehicle was instrumented. The methodology of the minimum weighted difference established was used to calculate the representative driving cycle. In addition, the variables that influenced the driving cycle and the calculation of autonomy such as vehicle dynamics parameters, weighting factors, average percentages of energy demand in the wheel, regenerative braking, vehicle autonomy, and calculation of the battery state of charge. Once the representative driving cycles were determined, they were Route 1, trip 5, trip 3 of Route 2, and Trip 5 of Route 3, then the average autonomy of 197 km was obtained on the three routes with a state of charge (SOC) greater than 70% in Ambato city.
