Abstract
LFP batteries are increasingly used in electric vehicles (EVs) and energy storage systems (ESS) due to their advantages in cycle life, safety, and cost. The optimal operating window for LFP batteries is typically around 15–35°C. Effective thermal management is critical for LFP batteries.
Today, most LFP cells—especially in EV applications—are packaged in prismatic form. Cold plates at the bottom of cells with circulating warm or cool fluid are commonly used to heat or cool the cells. To raise temperature more quickly, active heating is sometimes added, typically by placing a heating device outside the cell. The external heating elements must conduct heat from the cell surface inward.
