  • POWER SYSTEMS AND CONTROL METHODS TO ADDRESS PEAK LOADING
    Publication number: 20250088002
    Abstract: A power system includes an energy storage system having a rechargeable energy storage element and a converter connected to the rechargeable energy storage element and configured to connect to a bus so that the energy storage system is connected in parallel with a load and a main power supply system. The energy storage system may cooperate with the main power supply system to supply power to the load with each of the energy storage system and the main power supply system configured as a voltage source with a corresponding droop function. The system may include a control circuit configured to monitor a voltage of the bus and control the converter to either charge or discharge the rechargeable energy storage element based on the voltage of the bus.

    Abstract: A power system comprises an energy storage system including a rechargeable energy storage element and a converter connected to the rechargeable energy storage element and configured to connect to a bus so that the energy storage system is connected in parallel with a load and a main power supply system. The energy storage system cooperates with the main power supply system to supply power to the load. The power system may include a control circuit configured to monitor a voltage of the bus and control the converter to either charge or discharge the rechargeable energy storage element based on the voltage of the bus. The control circuit may also monitor a status of a state of charge (SOC) of the rechargeable energy storage element and a system load condition.

  • Battery equalization circuits for series charging/discharging and controlling methods thereof
    Patent number: 9368977
    Abstract: Battery equalization circuits for series charging/discharging and controlling methods thereof are provided. The provided circuit includes a set of series-connected batteries, a switching converter and a magnetic element coupled balance circuit including a magnetic element coupled to the switching converter, wherein the magnetic element takes a branch current from the switching converter to the series-connected batteries so as to cause the set of series-connected batteries to reach a balance.
