Roadmap tecnológico dos tipos de sistemas de gerenciamento térmico de baterias e suas aplicações no mercado brasileiro em veículos de passeio eletrificado

Abstract

In the last years, the use of lithium-ion batteries (LIBs) has been growing with the migration of automakers to manufacturing electric and hybrid vehicles. So far, LIB has been shown to be the most suitable battery technology for application in electric vehicles due to their energy storage capacity and life cycle. However, these features and safety are directly linked to temperature control. Due to the sensitivity of LIB to temperatures below 15 ° C and above 50 ° C, this research aims to evaluate the thermal management systems of batteries found in the literature and their applications in electrified passenger vehicles commercialized in the Brazilian market. This was done through the research and classification of data available in the literature, identification of the types of battery management systems adopted in these vehicles and, finally, a comparison between the literature and what is applied in the field. It was possible to identify that despite the various proposals for thermal management systems available in the literature, only two models are implemented for commercial purpose: air cooled and liquid cooled. Therefore, it is concluded that many of the improvement proposals are not mature enough for a scalable and marketable proposal.
