Patents by Inventor Gregory P. Fang

Gregory P. Fang 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).

  • Battery tester capable of predicting a discharge voltage/discharge current of a battery
    Patent number: 7081755
    Abstract: A method and apparatus is provided for determining how a vehicle battery would perform when used to start a vehicle. A discharge voltage/current of the battery is predicted as a function of a battery dynamic parameter, an open circuit voltage of the battery, a battery temperature and a fixed current/voltage value at which the battery is to be discharged. This discharge voltage/current value is compared to a minimum starting voltage/current required to start the vehicle in which the battery is employed and an output indicative of a starting capability of the battery is provided.
    Type: Grant
