Abstract

A hybrid power supply system includes a solar panel, a rechargeable battery for receiving electrical energy from the solar panel, a line power port, a switch capable of electrically connecting the line power port and the rechargeable battery, and a power sensor for acquiring an electrical energy value from the rechargeable battery and a controller. The controller receives the electrical energy value from the power sensor, and controls the switch to electrically connect the line power port and the rechargeable battery when a voltage of the rechargeable battery falls below a predetermined value. The line power port charges the rechargeable battery to one full cycle of power output of the rechargeable.

Claims

1. A hybrid power supply system comprising:

a solar panel;

a rechargeable battery for receiving electrical energy from the solar panel;

a line power port;

a switch capable of electrically connecting the line power port and the rechargeable battery;

a power sensor for acquiring an electrical energy value from the rechargeable battery; and

a controller receiving the electrical energy value from the power sensor, and controlling the switch to electrically connect the line power port and the rechargeable battery when a voltage of the rechargeable battery falls below a predetermined value, and the controller controlling the switch to electrically disconnect the line power port from the rechargeable battery when the charge on the rechargeable battery is equal to a power output cycle.

2. The hybrid power supply system of claim 1, further comprising an overcharge protector for the rechargeable battery.

3. The hybrid power supply system of claim 1, further comprising a converter for converting alternating current to direct current, which is input to the rechargeable battery.

4. A hybrid power supply system for an electrical device comprising:

a solar panel;

a rechargeable battery for receiving electrical energy from the solar panel, the rechargeable battery electrically connected to the electrical device;

a line power port;

a switch capable of electrically connecting the line power port and the rechargeable battery;

a power sensor for acquiring an electrical energy value from the rechargeable battery;

a switch controller capable of electrically connecting the line power port, the rechargeable battery and the electrical device selectively,

a controller receiving the electrical energy value from the power sensor and directing the switch controller to electrically connect the line power port and the electrical device, and the switch to electrically connect the line power port and the rechargeable battery when a voltage of the rechargeable battery falls below a predetermined value and to disconnect the line power port and the rechargeable battery when the charge on the rechargeable battery is equal to a power output cycle.

5. The hybrid power supply system of claim 4, further comprising an overcharge protector for the rechargeable battery.

6. The hybrid power supply system of claim 4, further comprising a converter for converting alternating current to direct current, which is then input to the rechargeable battery.
