Patents by Inventor Viktor Rozsnyay

Viktor Rozsnyay 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 current charger
    Publication number: 20090309553
    Abstract: The object of the invention is a method for charging a rechargeable battery having non-liquid electrolyte, which battery has an internal resonance frequency. The charging process contains at least one charging interval performed with current pulses, the frequency of said current pulses is essentially identical with the internal resonance frequency of the battery to be charged. Following the charging interval consists of periodic current pulses optionally a second relaxation interval is inserted, in which no charging current is applied to the rechargeable battery, within which optionally a second discharging interval is applied. After the second relaxation interval the charging is performed in an interval consists of a continuous charging current, whereafter an optional first relaxation interval is inserted, within which optionally a second discharging interval is applied. This sequence of the above steps can be varied and applied repeatedly until the full charge of the battery is attained.
