A Fast Lithium-Ion Battery Impedance and SOC Estimation Method Based on Two-Stage PI Observer
Due to the complex changes in battery state, the accurate and fast estimation of battery state of charge (SOC) is still a great challenge. Here, a fast estimation method of battery impedance and SOC based on a multi-level PI observer is proposed. The observer model reflects the change of the battery...
