Systems and Methods for Determining Battery State of Charge

摘要

Systems (50, 200) and methods for determining a state of charge of a battery (52, 102, 150, 202) are provided. The system (50, 200) includes a power source (56, 206) configured to provide a charging current to a battery (52, 102, 150, 202). A controller (54, 104, 204) is included and configured to determine a state of charge of the battery (52, 102, 150, 202) based on impedance of a battery (52, 102, 150, 202) during a discharge time period based on an impedance and a state of charge relationship of a battery (52, 102, 150, 202) during a charge time period.
