Patents by Inventor Lee Leppo

Lee Leppo 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: 5780991
    Abstract: A charging apparatus with multiple charge stations is disclosed. The apparatus includes a single power supply which operates under the control of a microprocessor to charge a plurality of battery packs disposed in respective charging stations. Associated with each charging station is a wiring harness assembly which includes an EEPROM memory chip having one or more stored charging algorithms for the type or types of battery packs to be charged at that charging station. The microprocessor reads the charging algorithm from a charging station's memory chip when a battery pack is inserted in the charging station. The microprocessor utilizes a feedback control loop including a resistor network to regulate the charging current and charging voltage supplied to each battery pack being charged. If a plurality of Li-Ion battery packs are disposed in respective charging stations, each pack is sequentially charged such that the voltage across the pack is raised to the rated output voltage of the pack.
