Análisis de operación de vehículos eléctricos en tracción, frenado reostático y regenerativo

Abstract

This study proposes the design and modeling of a lithium-ion battery system for an electric vehicle, evaluating its operation through simulations. The vehicle model is developed based on a typical trajectory in the city of Cuenca to determine speed and power requirements. Using this information and a detailed modeling of battery charging and discharging, their behavior is determined considering both conventional and regenerative braking. The indicators State of Charge (SOC) and State of Health (SOH) are utilized for this study. Additionally, a series of tests are conducted to obtain a precise analysis of the electric vehicle's range, considering charge and discharge cycles that can impact the health and life cycle of batteries.
