Discover the essential aspects of battery pack technology, including key components such as cells, BMS, structural components, thermal management, production processes, and vital technical parameters. . The motivation of this paper is to develop a battery management system (BMS) to monitor and control the temperature, state of charge (SOC) and state of health (SOH) et al. and to increase the efficiency of rechargeable batteries. This integrated system powers everything from electric vehicles to renewable energy storage. . The lithium-ion battery module and pack production line is a complex system consisting of multiple major units and associated equipment that work in concert to achieve high quality lithium-ion module and pack production. The production line starts with the battery cell handling equipment, which is. . We combine high energy density batteries, power conversion and control systems in an upgraded shipping container package. Lithium batteries are CATL brand, whose LFP chemistry packs 1 MWh of energyinto a battery volume of 2. 88 m3 weighing 5,960 kg. Our design incorporates safety protection. . The packaging and assembly of lithium-ion battery packs are crucial in the field of energy storage and have a significant impact on applications like electric vehicles and electronics. The pack line process consists of three main phases: production, assembly, and packaging. Understanding how battery packs are manufactured is crucial as industries demand higher performance and sustainability. From raw material selection to final assembly, each step. .
