Abstract

A battery replacing system for replacing a battery of an electronic device, includes a power storage unit and a switch circuit. The power storage unit can be charged by the battery when the battery is mounted to the electronic device. The switch circuit alternatively connects one of the power storage unit or the battery to an operating system of the electronic device. The switch connects the power storage unit to the operating system to have the power storage unit provide power to the operating system when the battery is detached from the electronic device, and connect the battery to the operating system to have the battery provide power to the operating system when the battery is mounted to the electronic device.

Claims

1. A battery replacing system for replacing a battery of an electronic device, comprising:

a power storage unit adapted to be charged by a battery attached to an electronic device; and

a switch circuit connecting either the power storage unit or the battery to an operating system of the electronic device;

wherein when the battery is detached from the electronic device, the switch circuit connects the power storage unit to the operating system so that the power storage unit provides power to the operating system; and

when the battery is attached to the electronic device, the switch connects the battery to the operating system so that the battery provides power to the operating system.

2. The battery replacing system of claim 1, wherein a charging circuit is connected between the battery and the power storage unit, and the battery charges the power storage unit via the charging circuit when the battery is attached to the electronic device.

3. The battery replacing system of claim 1, comprising a power supply control circuit configured to detect whether the battery is attached to the electronic device.

4. The battery replacing system of claim 3, wherein the power supply control circuit is connected to the switch circuit, and the power supply control circuit is configured to control the switch circuit.

5. The battery replacing system of claim 4, wherein the power supply control circuit is connected to a battery replacing control module, and the battery replacing control module is configured to be trigged to send a battery replace signal to the power supply control circuit, and the power supply control circuit is further configured to control the switch circuit to connect the power storage unit to the operating system when the power supply control circuit receives the battery replace signal.

6. The battery replacing system of claim 5, wherein the power supply control circuit is further configured to control the switch circuit to connect the battery to the operating system when the power supply control circuit detects that the battery is attached to the electronic device.

7. The battery replacing system of claim 5, wherein the power supply control circuit is connected to a power saving control module, and the power saving control module is configured to turn the operating system from a normal mode into a power-save mode when the power supply control circuit receives the battery replace signal.

8. The battery replacing system of claim 7, wherein in the power-save mode, peripheral devices of the electronic device are shut off and a screen of the electronic device turns dark.

9. A battery replacing method, comprising:

when an used battery of an electronic device needs to be replaced, triggering an battery replacing control module to send a battery replace signal to a power supply control circuit;

controlling a power storage unit to provide power to the electronic device;

replacing the used battery with a new battery attached to the electronic device; and

controlling the new battery to provide power to the electronic device and controlling the power storage unit to stop providing power to the electronic device.

10. The battery replacing method of claim 9, comprising charging the power storage unit by the new battery charges unit until the power storage unit is fully charged after the new battery is attached to the electronic device.

11. The battery replacing method of claim 9, comprising causing the electronic device to switch from a normal mode to a power-save mode when the power storage unit provides power to the electronic device.

12. The battery replacing method of claim 11, further comprising causing peripheral devices of the electronic device to shut off and causing a screen of the electronic device to turn dark when the electronic device is in the power-save mode.

13. The battery replacing method of claim 11, further comprising causing the electronic device to return to the normal mode when new battery provides power to the electronic device.

14. The battery replacing method of claim 9, comprising connecting a charging circuit between the new battery and the power storage unit so that the power storage unit is charged by the new battery.
