A multi-node thermal system model for lithium-ion battery packs

Temperature is one of the main factors that control the degradation in lithium ion batteries. Accurate knowledge and control of cell temperatures in a pack helps the battery management system to maximize cell utilization and ensure pack safety and service life. In a pack with arrays of cells, a cell's temperature is not only affected by its own thermal characteristics but also by its neighbors, the cooling system and pack configuration, which...
