  • Patent number: 11909249
    Abstract: A power feeding system of the present disclosure includes a control unit. In a case where a magnitude of supply destination power is smaller than an upper limit value of the power supply capability of the power source, the control unit controls the charge/discharge control circuit so as to meet the supply destination power based on power output from the power source, and to charge the storage battery with power which is a difference obtained by subtracting the supply destination power from the upper limit value of the power supply capability of the power source. In a case where the magnitude of the supply destination power is more than or equal to the upper limit value of the power supply capability of the power source, the control unit controls the charge/discharge control circuit so as to meet the supply destination power by both the power source and the storage battery.

  • Patent number: 11909204
    Abstract: A control system may include a direct-current (DC) power bus for charging (e.g., trickle charging) internal energy storage elements in control devices of the control system. For example, the control devices may be motorized window treatments configured to adjust a position of a covering material to control the amount of daylight entering a space. The system may include a DC power supply that may generate a DC voltage on the DC power bus. For example, the DC power bus may extend from the DC power supply around the perimeter of a floor of the building and may be connected to all of the motorized window treatments on the floor (e.g., in a daisy-chain configuration). Wiring the DC power bus in such a manner may dramatically reduce the installation labor and wiring costs of an installation, as well as decreasing the chance of a miswire.
