Enhancing Electric Vehicle Autonomy With Solar Energy: A Case Study of the “Takai Urban” in Northern Chile

Abstract

The global transition towards electromobility presents unique challenges, particularly in regions with limited infrastructure. In Northern Chile, the sparse distribution of charging stations, with distances often exceeding 100 km, complicates the widespread adoption of electric vehicles (EVs). This study investigates the feasibility of enhancing the autonomy of the "Takai Urban", a solar-assisted battery EV through the integration of Zebra IBC solar cells, leveraging the region's high solar irradiance. Initially, the Takai urban EV had a maximum range of 70 km per charge. Through virtual modelling and simulations, which incorporated GPS and meteorological data along a typical 43.3 km route in Antofagasta city, we examined the impact of solar integration on vehicle performance. The simulations indicated that with the strategic placement of high-efficiency solar cells, the vehicle's range could be extended by approximately 48%, achieving a new maximum of 104 km per charge. This approach not only demonstrates the potential for solar-assisted EVs in regions like Northern Chile but also underscores the broader implications for sustainable mobility in similar environments globally. The results highlight the potential for practical enhancements in EV designs using solar technologies, focusing on efficiency improvements and sustainable mobility solutions.
