Chit Fung So 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: 11689044
    Abstract: A battery with a battery management system is capable of charging the battery with recaptured energy from an energy regeneration device. The battery management system charges the battery with the energy regeneration device if the output voltage from the energy regeneration device is larger than the charging voltage of the battery.
    Type: Grant

  • Patent number: 11682913
    Abstract: A lithium battery designed to replace lead-acid battery. The lithium battery has a plurality of battery cells connected in series and a battery management unit. The battery management unit includes a controller, a sensing unit connected to the plurality of battery cells and the controller, a charging control unit connected to the controller, and a discharging control unit connected to the controller. The battery management unit prevents the batteries connected in parallel from mutually charging each other and also prevents the batteries being depleted completely by outputting a low voltage in pulse mode when the battery has low charge.

  • Publication number: 20220399725
    Abstract: A battery with a battery management system and a wireless communication module is capable of charging the battery with recaptured energy from an energy regeneration device. The battery management system charges the battery with the energy regeneration device if the output voltage from the energy regeneration device is larger than the charging voltage of the battery. The battery management system can enable and disable charging of the battery with the energy from the energy regeneration device according to an instruction received wirelessly.
