Abstract: Low-complexity and accurate state of health (SoH) estimation of series-connected batteries has always been a difficult problem to solve in a well-designed battery management system (BMS). Lithium iron phosphate (LiFePO4) battery has been widely used as an energy storage carrier due to its better safety and longer cycle life.

e market. The five key indicators to evaluate a lithium-ion battery are energy density, cost, safe y, cycle life, and power density. At this stage NMC/NCA with higher energy density has attracted the most attention in the EV field. However, a higher e battery fire (e.g. frequent spontaneous combustion of Tesla model S serie
Good measurement accuracy is always required, especially the cell voltage, pack current, and cell temperature. Precision is necessary for accurate protections and battery pack state of charge (SoC) calculations. This is especially true for LiFePO4 battery pack applications because of the flat voltage.
