Systems and methods for determining state of health (SOH) of a battery. For example, a method includes conditioning the battery by determining an initial state of charge of the battery; charging the battery from the initial state of charge to a first target state of charge via a predetermined multi-stage charging sequence; and determining SOH of the battery by charging the battery from the first target state of charge to a second target state of charge at an ICA charging rate; acquiring a voltage vs. capacity (QV) data of the battery during charging of the battery from the first target state of charge to the second target state of charge; obtaining an incremental capacity (IC) data based on at least the acquired QV data; pre-processing the IC data; extracting an incremental capacity analysis (ICA) peak from the IC data; and determining the SOH of the battery based upon the ICA peak.
