Understanding Business Models in the Brazilian Context of Electric Mobility: A Proposed Framework Márcio Có, Flávia Consoni, Matheus Coelho Carneiro, Guilherme Fernandes, Reginaldo Barbosa Nunes, et al. Urban Science, 2024 In the transition to electric mobility (EM), business model innovation plays a crucial role in expanding the use of electric vehicles and increasing acceptance of this technology. The transition pathways differ between countries in the largest economies and those in Latin America. Brazil presents a unique scenario, benefiting from an early start with biofuels, the production of flex-fuel vehicles, predominantly renewable electric energy generation (>80%), and the absence of a structured national policy aligned with local governments. This study introduces a framework that surveys and categorizes businesses in EM, relating them to sustainable development aspects and regulatory maturity. It builds a solid conceptual foundation, incorporating data from technical and commercial events, as well as interviews with Brazilian specialists for validation. The proposed framework aids in understanding the Brazilian context, identifying regulatory gaps, and developing a common language to advance studies on business model innovation, contributing to electromobility studies in Latin America. Additionally, it can guide the construction of regional and local public policies and help identify more sustainable projects.
Analysis of the Effectiveness of the Social Electricity Tariff in Serving the Target Public: Case Study in the State of Espírito Santo (Brazil) Considering the Current Situation and New Project Laws Scenarios Kemily Monteiro Cardoso Goularte, Pablo Rodrigues Muniz, Reginaldo Barbosa Nunes 2023 15th IEEE International Conference on Industry Applications Induscon 2023 Proceedings, 2023 The Electric Energy Social Tariff (TSEE) is a social benefit created by the Federal Government of Brazil in 2002 to benefit energy consumers from the Low-Income Residential Subclass by granting discounts on the electricity bill. In an audit carried out by the Federal Court of Auditors (TCU - Tribunal de Contas da União - in Portuguese), it was found that the criterion for including families in the subsidy - monthly electricity consumption - is ineffective, since it has a low relationship with family income. Another audit carried out by the TCU discovered the lack of strategic design and key indicators for this social subsidy. Given this, this paper characterizes the per capita income profile and discounts granted to these families, focusing on the Brazilian State of Espírito Santo. The impacts of two law projects that are being discussed in the Brazilian Senate were also analyzed. The results indicate that families with higher per capita income predominantly receive more significant discounts on their electricity bills, confirming the audits' hypothesis. It was also found that the law projects improve the situation a little, but maintain this inconsistency and increase the financial value of the subsidy granted.
Development and Evaluation of an AI-based Smart Charging System for Electric Vehicles Raphael Cruz Alves, Rodrigo Varejão Andreão, Reginaldo Barbosa Nunes 2023 15th IEEE International Conference on Industry Applications Induscon 2023 Proceedings, 2023 The rapid adoption of electric vehicles (EVs) necessitates advanced and efficient charging management systems. This paper introduces an AI-based charging system that emphasizes the importance of load management, equitable energy distribution, and the detection of charging anomalies. Designed to provide users with accurate cost forecasts and proactive anomaly detection, our proposed system aims to enhance the EV charging experience. Implemented on the Azure cloud platform, the system's core functionalities have been proven effective. Through a case study conducted in Espírito Santo, Brazil, we demonstrate the capability of our system to improve the EV charging infrastructure. While the potential for integration with smart grid data exists, the primary focus of this work is on the standalone capabilities of the charging system, laying the groundwork for future smart grid integrations.
Greenhouse Gas Emissions Estimation with Electric Vehicles Penetration in the Brazilian Power Grid Vinícius S. De Melo, Renner S. Camargo, Filipe Krebel, Marcelo Brunoro, Weder T. Nunes, et al. 2023 15th IEEE International Conference on Industry Applications Induscon 2023 Proceedings, 2023 With the growing rate of greenhouse gas emissions in the transport sector, research and development of new technologies for producing less polluting and more efficient combustion engines have been constant. However, the reductions have not been so significant, as the vast majority of these engines are still dependent on fossil fuels. Electric Vehicles are one of the main alternatives for reducing greenhouse gases. However, its high cost and charging infrastructure are still barriers in the current scenario, but, in the long term will become highly competitive and tend to dominate the market in the transport area. In this work, projections of the light vehicle fleet evolution in Brazil will be presented, until 2050, considering the penetration of the main types of electric vehicles. Based on government data from the expansion of the interconnected electrical system, estimates of indirect emissions from recharging electric vehicle batteries are presented for low and high-electric mobility scenarios. Estimates show a significant reduction in CO2 emissions, even considering the low mobility scenario, where part of the combustion fleet is still present. A particularity is observed about plug-in hybrid vehicles, as their autonomy in electric mode is sufficient for daily driving demands, and emissions may suffer more significant reductions.
The impact of electric vehicles insertion in the Brazilian electric matrix Filipe Krebel, Weder Tótola Nunes, Vinícius Secchin De Melo, Renner Sartório Camargo, Monique Cardoso Fernandes, et al. 2023 15th IEEE International Conference on Industry Applications Induscon 2023 Proceedings, 2023 Climate change and the future scarcity of fossil fuels are driving the actions of the so-called energy transition. The transport sector is at the center of this problem and the introduction of electric vehicles is appearing as the main solution for this sector. However, the possibility of a mass insertion is surrounded by doubts about the impacts on energy demand. Some works analyzed the Brazilian scenario considering different EV insertion rates in a short time interval. Unlike what is found in similar works, this study tries to approach a scenario that takes into account the socioeconomic aspects of Brazil to analyze the impacts that the introduction of the electric fleet will bring to the national electric matrix. The results indicate that this insertion will be slow and gradual, with negligible impacts in the first decades.
