Resumo
O presente trabalho tem como foco apresentar um estudo comparativo acerca da eficiência e dos benefícios trazidos pelas baterias aos carros elétricos. Atualmente, o número de veículos produzidos a partir dessa tecnologia tem alcançado números significativos mundialmente. Fator que leva as empresas a se envolverem cada vez mais em estudos que culminem na produção de baterias eficientes, potentes, autônomas e capazes de atender aos anseios de toda população quanto à poluição ambiental, visto que os carros convencionais (a combustão) emitem um número alarmante de CO2². As baterias de Íons-lítio são as mais utilizadas nesses veículos, por serem recarregáveis e rentáveis. Já as baterias em estado sólido, vem apresentando vantagens para esse mercado devido, dentre outras vantagens, à maior autonomia que oferecem para os carros. Nessa concepção, o estudo buscou, a partir de modelagem na plataforma Pamvec, discutir sobre essas duas baterias, identificando os benefícios e inovações trazidos para esse mercado. Inferiu-se a partir dos estudos que os fabricantes de carros elétricos estão constantemente buscando por inovações e desenvolvimento de baterias que supram as necessidades de autonomia e potência dos seus veículos, com destaque para a bateria em estado sólido que, provavelmente se tornará a solução mais viável para esse segmento.
The present work aims to present a comparative study about the efficiency and benefits brought by batteries to electric cars. Currently, the number of vehicles produced from this technology has reached significant numbers worldwide, a factor that leads companies to become increasingly involved in studies that culminate in the production of efficient, powerful, autonomous batteries capable of meeting the desires of the entire population. as for environmental pollution, since conventional cars (combustion) emit an alarming number of CO². Lithium-ion batteries are the most used in these vehicles, as they are rechargeable and cost-effective. Solid state batteries, on the other hand, have been showing advantages for this market due, among other advantages, to the greater autonomy they offer for cars. In this conception, the study sought, based on modeling on the Pamvec platform, to discuss these two batteries, identifying the benefits and innovations brought to this market. It was inferred from the studies that electric car manufacturers are constantly looking for innovations and battery development that meet the autonomy and power needs of their vehicles, with emphasis on the solid-state battery, which will probably become the most efficient solution. viable for that segment.
