Análise técnica e de desempenho do CARPORT instalado na UTFPR campus Neoville associado a diferentes veículos elétricos em Curitiba

Abstract

This work presents the performance analysis of the solar parking lot (CARPORT) installed at UTFPR Neoville from July 2019 to December 2023. There is also a presentation of the energy generated by CARPORT for the energy consume of 5 different electric vehicles in the city of Curitiba – the Renault Fluence ZE, Nissan Leaf, Renault Kwid E-tech and two newer models: BYD Dolphin GS 180EV and BYD Dolphin Plus 310E, all 100% electric. A qualitative interview about the perception of electric vehicle owners towards combustion vehicles is also presented. Finally, a discussion on maintenance and modules cleaning in relation to system performance is also presented. The energy generated by CARPORT can meet the average daily energy need for transportation by a person from Paraná using any of the 5 Electric Vehicles studied. The best-selling BYD Dolphin models in February 2024 showed 9.25% lower consumption and 80.5% higher autonomy than the Electric Vehicles initially studied. CARPORT’s merit indices were collected between July 2019 and December 2023, totaling 54 samples and they are in accordance with literature data for this type of system. Washing the CARPORT modules represents an average of 8% improvement in the system’s performance rate. There is also a presentation of the results of interviews with 52 electric vehicle owners in Brazil. In general, owners are satisfied with the autonomy of their vehicle and would not use combustion vehicles again. On the other hand, 37% of those interviewed point to the poor infrastructure for using their electric vehicles as a problem for the growth in their use. Many interviewees report the exemption from IPVA and IPI as a perceived financial advantage for purchasing their vehicle. Half of those interviewed indicate complete satisfaction with the use of their EV. 90% of respondents recharge their EV at home and 60% of them have their own photovoltaic energy generation. The discussion about the sudden change in the consumption of Evs and the new tax collection on Evs in Paraná, for example, are also presented in the work. The purpose of this work is to continue the practicalanalysis of CARPORT performance indices and encourage the acquisition and use of new electric vehicles on the market.
