A method and system for estimating instantaneous state-of-charge (SOC) of a lithium ion battery having a lithium manganese oxide (LMO), lithium iron phosphate (LFP), lithium nickel manganese cobalt oxide (NMC), lithium nickel cobalt aluminum oxide (NCA), or lithium titanate (LTO) chemistry. Voltage across and current through the battery are determined at two different times using two loads having different impedances. An instantaneous internal resistance and open circuit voltage (OCV) of the battery are then estimated using this data, and from the OCV the SOC is estimated. |
