Trabalho completo:

Com a globalização da eletrificação, o setor automotivo brasileiro está incorporando tecnologias para adequar a sua frota às regulamentações de emissões de CO2. Os ônibus elétricos foram os primeiros projetos nacionais desenvolvidos com esse propósito, sendo motivados pela Lei nº 16.802 (31), de 17 de janeiro de 2018, da cidade de São Paulo, que estabeleceu metas de redução da emissão de poluentes no setor de transporte público. Este estudo investiga detalhadamente a influência da arquitetura térmica na refrigeração das baterias de lítio desses ônibus, reconhecendo sua importância crítica para garantir desempenho otimizado, vida útil prolongada e segurança operacional dos veículos. O Battery Thermal Management System (BTMS) é apresentado como uma solução inovadora para o gerenciamento térmico, destacando sua função primária de manter a temperatura adequada das baterias, mas também a necessidade de uma arquitetura térmica cuidadosamente projetada para otimizar seu dimensionamento e eficiência. Ao examinar esses aspectos, este trabalho contribui para uma compreensão mais aprofundada da complexa interação entre a arquitetura térmica e o BTMS.

With the globalization of electrification, the Brazilian automotive sector is incorporating technologies to adapt its fleet to CO2 emissions regulations. Electric buses were the first national projects developed for this purpose, being motivated by Law No. 16,802 (31), of January 17, 2018, of the city of São Paulo, which established targets for reducing pollutant emissions in the public transport sector. This study investigates in detail the influence of thermal architecture on the cooling of the lithium batteries of these buses, recognizing their critical importance in ensuring optimized performance, extended useful life and operational safety of the vehicles. The Battery Thermal Management System (BTMS) is presented as an innovative solution for thermal management, highlighting its primary function of maintaining the appropriate temperature of batteries, but also the need for a carefully designed thermal architecture to optimize their sizing and efficiency. By examining these aspects, this work contributes to a deeper understanding of the complex interplay between thermal architecture and BTMS.
