Due to the needs of teaching and scientific research, they need to build a cylindrical cell pilot line and a pouch cell pilot line in the laboratory. Our client is IITB. They have their own lithium-ion battery laboratory. Due to the needs of teaching and scientific research, they need to build a cylindrical cell pilot line and a pouch cell pilot line in the laboratory. The customer has made a lot of research achievements in the field of lithium-ion batteries, but the research and development of batteries cannot be completed overnight. From laboratory research and development to production line production is not a simple amplification. Every mature battery system needs to go through countless verifications. The research and development of batteries also needs to go through the research and development process of laboratories, pilot tests and small batch trial production. The pilot test line refers to the medium-scale production line before the formal mass production, which also has the test function of improving observation. Based on this, the purpose of the customer to establish a battery pilot test line is mainly for the verification of hardware, structure, software, process, testing, materials, quality, etc., and to fully verify the producibility of its batteries.
