Publication number: 20240145856Abstract: The present disclosure relates to the technical field of batteries, and specifically relates to a busbar-less battery module and a battery pack. The busbar-less battery module provided in the present disclosure includes a plurality of cells, and tabs are provided at both ends of each cell, and the interconnected cells are directly connected through the tabs, and an isolation component is provided between the adjacent cells. In the present disclosure, the tabs are directly connected, and omission of bus bars prevents the bus bar from blocking the high-temperature fume, so that the high-temperature fume may be exhausted in time when thermal runaway occurs. In the meantime, the tabs of the cell may be isolated to prevent adjacent tabs from contacting each other during operation and causing thermal runaway due to short circuit, thereby avoiding spread of heat at the tabs.Type: ApplicationFiled: December 31, 2021Publication date: May 2, 2024Applicants: AESC Dynamics Technology (Jiangsu) Ltd., AESC Intelligent Innovation Dynamics Technology (Shanghai) Ltd.Inventors: Zhuolie Chen, Xin Cui, Dengke LI, Yafei He
