Abstract

An uninterruptible power control method includes the steps of: reading a detection result from a motion sensor of an electronic device, determining whether the detection result meets a movement condition, and turning on a power supply path of a sub-battery module of the electronic device when the detection result meets the movement condition. The electronic device is powered by a primary battery module in normal state, and the sub-battery module is built in the electronic device.

Claims

1. An uninterruptible power control method, comprising the steps of:

supplying power to a power input end of an electronic device in a normal state by a primary battery module via a first power supply path;

reading a detection result from a motion sensor of the electronic device, wherein the motion sensor senses motion of the electronic device;

determining whether the detection result meets a motion condition;

turning on a second power supply path of a secondary battery module to the power input end of the electronic device when the detection result meets the motion condition, wherein the secondary battery module is built in the electronic device, and wherein the primary battery module and the secondary battery module are electrically connected to the power input end in parallel when the second power supply path is turned on.

2. The uninterruptible power control method of claim 1, further comprising the step of supplying no power from the secondary battery module when the detection result does not meet the motion condition.

3. The uninterruptible power control method of claim 1, further comprising, after the step of turning on the second power supply path of the secondary battery module of the electronic device, the steps of:

reading at least one other detection result after the detection result;

determining whether the at least one other detection result meets the motion condition; and

turning off the second power supply path of the secondary battery module upon determination that the at least one other detection result does not meet the motion condition.

4. The uninterruptible power control method of claim 1, further comprising, after the step of turning on the second power supply path of the secondary battery module of the electronic device, the steps of:

detecting whether the primary battery module supplies power; and

turning off the second power supply path of the secondary battery module upon detection that the primary battery module supplies power.

5. The uninterruptible power control method of claim 4, wherein the step of detecting whether the primary battery module supplies power to the power input end begins when the detection result meets the motion condition.

6. The uninterruptible power control method of claim 5, wherein, upon detecting that the primary battery module supplies power to the power input end, a predetermined time period is allowed to elapse before turning off the second power supply path of the secondary battery module.

7. The uninterruptible power control method of claim 1, wherein the secondary battery module is connected to the power input end through a switch module, and the turning-on step builds the second power supply path of the secondary battery module by turning on the switch module.

8. The uninterruptible power control method of claim 1, wherein the motion sensor comprises one of a G-sensor, a gyroscope sensing unit, and a combination thereof, and the detection result comprises one of a gravity information, a posture information, and a combination thereof, of the electronic device.

9. The uninterruptible power control method of claim 1, wherein the primary battery module has a larger capacitance than the secondary battery module.

10. The uninterruptible power control method of claim 1, wherein the motion condition is that acceleration is larger than 0.2G, or that angular velocity about any one of X-axis, Y-axis, and Z-axis is larger than 5°

per second.
