Patents by Inventor Dale Allen Blackwell

Dale Allen Blackwell has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • System and method for sensing battery capacity
    Patent number: 11346888
    Abstract: One embodiment of the invention includes a battery sense system. The system includes a temperature sensor configured to measure a temperature of a battery and a memory configured to store predetermined data associated with steady-state and transient behaviors of the battery relative to a depth of discharge (DOD) of the battery. The system also includes a controller configured to measure a voltage of the battery and to calculate a state of charge (SOC) of the battery based on the voltage, the predetermined data, and the temperature.
    Type: Grant
    Filed: November 19, 2020
    Date of Patent: May 31, 2022
    Assignee: TEXAS INSTRUMENTS INCORPORATED
    Inventors: Yevgen Barsukov, Yandong Zhang, Dale Allen Blackwell
  • Voltage based zero configuration battery management
    Patent number: 11169213
    Abstract: Controllers and methods to manage a battery, in which a controller estimates scale factor and a steady state current rate according to multiple battery voltage values and a steady state model during steady state operation, and estimates the current rate according to a battery voltage value, the scale factor, and a dynamic model of the battery during dynamic operation, and the controller estimates a remaining capacity of the battery according to the current rate, without requiring controller reconfiguration for different batteries.
