  "textContent": "A state of charge (SOC) determination method and apparatus for a battery system are disclosed. Based on a correspondence between impedance and SOC, a correspondence between OCV and SOC, and an operating current at a previous data collection moment, a correction coefficient at a current data collection moment can be determined(S101). After the SOC estimated at the current data collection moment is corrected based on the correction coefficient(S102-S103), the accumulation of errors in the SOC can be eliminated, and the accuracy of the determined SOC is thereby improved.",
