Implementation of a Photovoltaic Panel to Supply Electric Cars Energy Demands

Abstract

The gradual shifting of the energy matrix to renewable sources is one of the main global strategies for sustainable development. According to studies, the use of electric energy by automobiles would lead to a reduction in gasoline consumption of 40.7% in 2031, accompanied by an increase in electricity consumption of 42.1% in relation to official projections. However, the gradual and constant dissemination and use of electric vehicles, a new paradigm emerges, which is the need to supply the energy demand of this new charge in the electric system The use of solar radiation to generate electricity to meet this new demand presents a sustainable alternative. From these questions, a structure was designed with the installation of a photovoltaic solar panel linked to the use of electric vehicles, analyzing estimated values of energy production and avoided emissions of CO2, compared to the average consumption of several models to cover 21,900km per year. The results show that the Renault Twizy was the only model whose consumption was below the energy production of the projected photovoltaic system. In contrast, all models had a positive balance in the estimates of avoided CO2, forming an environmentally sustainable solution.

PV - Battery Energy Storage Progress in Brazil: A Review

“…Another possible application for them is to provide peak shaving services in buildings, as this energy stored in electric and hybrid vehicles is not fully used daily. In this context, Silva et al [74] and Silva [75] developed a prototype of a self-sufficient PV-EV that can be charged by the power grid or PV system, also capable of providing peak-shaving services.…”
