  • State-of-charge detection device for a battery
    Patent number: 6653817
    Abstract: A method and apparatus for improving estimation of battery impedance when determining the state of charge of a battery including injecting a wide spectrum signal continuously across a battery when the battery is in generator mode. Additionally, the wide spectrum signal may be injected across an alternator of a conventional internal combustion engine to improve estimation of battery impedance and subsequent state of charge the battery.
    Type: Grant
    Filed: June 26, 2001
    Date of Patent: November 25, 2003
    Assignee: General Motors Corporation
    Inventors: Edward Dean Tate, Jr., Mark William Verbrugge, Shawn D. Sarbacker
  • State of charge method and apparatus
    Patent number: 6639385
    Abstract: A method for determining state of charge (SOC) of a battery system based upon an equivalent circuit of the battery system. A potential and resistance of the equivalent circuit are computed. The method uses a least squares regression means, and includes: providing a plurality of data points as a starting point based upon determinations including measurement or prior computation, wherein the determinations include a determination of a voltage of the battery system; weighting the plurality of data points; and computing values of the resistance and potential based upon weighted data points using recursive formulas, wherein only a state at a previous time is reflected respectively.

  • State of charge prediction method and apparatus for a battery
    Patent number: 6441586
    Abstract: A method of determining the state of a battery including the steps of generating a state vector that describes the state of the battery, predicting a response for the state vector, measuring a response of the battery, and correcting the state vector based on the differences between the predicted response and a measured response to determine the state of the battery.

  • Quasi-adaptive method for determining a battery's state of charge
    Patent number: 6359419
    Abstract: A method and apparatus for determining the state of charge of a battery including determining a current-based state of charge measurement based on coulomb integration, determining a voltage-based state of charge measurement based on the resistance of said battery and a hysteresis voltage, and combining the current-based state of charge measurement and the voltage-based state of charge measurement to generate the state of charge measurement of the battery.
