Patents by Inventor Jean-Pierre Vaillancourt

Jean-Pierre Vaillancourt 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).

  • Patent number: 7307402
    Abstract: A method of charging an electrochemical generator having a plurality of electrochemical cells. The method includes the step of charging the plurality of electrochemical cells such that the total voltage of the generator reaches a predetermined voltage level, followed by the steps of selecting a particular electrochemical cell and charging the particular electrochemical cell to its respective maximum voltage, such that the cathode(s) of the particular electrochemical cell is(are) restored to a fully-charged state. Once it has been restored to its fully-charged state, the particular electrochemical cell is allowed to discharge itself down to a nominal voltage. Each of the plurality of electrochemical cells of the generator is selected and charged to its respective maximum voltage in turn, according to a predetermined selection sequence.
    Type: Grant

  • Patent number: 7132832
    Abstract: A self-diagnosis system for an energy storage device, the latter including a plurality of electrochemical cells connected in series or parallel to form a cell string. The self-diagnosis system correlates a state of health of the battery based on the internal resistance value of each electrochemical cell of the energy storage device and determines a corresponding battery initial capacity which enables the self-diagnosis system to evaluate the exact capacity of the battery at any given time.
