What the paper says

Electric vehicles (EVs) offer a strategic solution to environmental challenges by combining energy efficiency with reduced emissions. This study conducts a bibliometric analysis and technological mapping of the sector, comparing Brazil’s position to that of leaders such as China, the United States, and Germany. The objective is to identify trends in the national development of EVs, with a focus on scientific and technological production. The methodology involves collecting and analyzing data from bibliographic databases (Web of Science) and patent databases (Derwent Innovation Index), encompassing scientific publications and technological records. The central issue is Brazil’s low scientific and technological output, despite its renewable energy potential, which reflects a dependence on foreign technologies and a lack of integration among academia, industry, and government. The rationale for this study is rooted in the need to understand how Brazil can position itself competitively in the global EV market, considering its clean energy matrix and programs like Rota 2030. The results indicate that China leads in battery technology and infrastructure, while Brazil showcases low scientific output and a reliance on foreign technology. Despite its renewable energy matrix and initiatives like Rota 2030, there is an absence of integrated policies for innovation. It is concluded that Brazil must strengthen its scientific research, integrate academia with the productive sector, and invest in infrastructure to compete in the global electric vehicle market.
