Determinación de la demanda energética en un vehículo eléctrico y análisis del rendimiento del sistema de propulsión en ciclos urbanos en una ciudad de altitud

Abstract

The Ecuadorian automotive industry is currently working on the inclusion of new mobility technologies, but due to the lack of knowledge regarding the autonomy and guarantees that electric vehicles offer, they reduce the interest of users in acquiring these vehicles. Therefore, this work determined the energy demand of an electric vehicle and the analysis of the performance of the propulsion system by means of urban cycles in an altitude city, opting for the analytical-synthetic method which allowed us from a data collection, the generation of variables that were later analyzed, for its execution a total of 19 trips were made covering the busiest and crowded areas of Ambato city. To obtain the typical driving cycle, the statistical method of the minimum weighted differences was applied, while the energy demand was established from the application of vehicle dynamics, this analysis, together with other parameters, will determine the energy consumption of the electric vehicle. Thus, the data obtained in these routes helped to perform an estimated analysis of the electrical energy consumption, establishing that the force due to the slope and the inertia force represent a significant percentage in the wheel energy consumption due to the geographic conditions of each route and because these forces depend directly on the vehicle mass. Therefore, the representative driving cycle of each of the routes and the value of the energy demand were determined where route 5 of route 1 generated a wheel energy consumption of 4.64 kWh, journey 1 of route 2 with a consumption of 6,77 kWh and journey 5 of route 3 with an energy consumption of 3,91 kWh.
