Portable electronic device automatically judging whether to charge

Abstract

This invention discloses a portable electronic device able to automatically judge if it needs charging. In the portable electronic device equipped are: a processor, a detector, a switching unit, a power storage unit. A connecting part is equipped on the surface of the device, when said part receiving a power source signal, and said detector detects that the power volume in the power storage unit meets the standard level of power storage, and then produces a detection signal. Based on this signal, the processor switches the switching unit, and makes the external power can not be delivered into the power storage unit via the connecting part and the switching unit.

Description

technical field [0001] The present invention relates to a portable electronic device, in particular to a power storage part installed in a portable electronic device, which can only be charged when the power capacity of the power storage part meets a low-capacity standard. Background technique [0002] Now our life is entering an information age where the electronic industry is booming. Various high-tech electronic products derived from digital technology are developing rapidly. Various electronic components and interface devices installed on electronic equipment are constantly being used. It has been developed and widely used in all walks of life in their living and working environments, which has indeed brought a great breakthrough to the development of human science and technology. This development trend not only accelerates the speed and efficiency of information circulation, but also provides It brings great convenience to people's life and work. However, with the cont...

Problems solved by technology

[0003] Generally, portable electronic devices are equipped with at least one battery, and each battery can be charged and used again. However, the battery itself has a certain service life. In other words, after a certain number of charging times, the battery The battery cannot be charged again and can be used by portable electronic devices. Therefore, the industry has designed a method that can cut off the relevant charging circuit in the portable electronic device when the battery is fully charged to make the battery In this way, the battery can be prevented from continuing to be charged after being fully charged, thereby shortening the life of the battery; however, although the industry adopts the design of stopping charging when the battery is fully charged, the battery has not reached When the charge is full, the battery only needs to be charged, so that the battery cannot be fully used effectively during the limited service life of the battery

[0004] What's more, the USB and power supply dual-purpose signal transmission line used in the industry (such as: Mio168 USB synchronization line), the signal transmission line can transmit data signals and power signals at the same time, so when the signal transmission line is connected to a general portable electronic device , when the signal transmission line transmits data signals and power signals at the same time, when the battery of the portable electronic device is fully charged, since the signal transmission line is still transmitting data signals, the portable electronic device cannot stop operating, so the battery will continue The ground is in a charging state until the signal transmission line is removed. In this way, charging a saturated battery not only shortens the life of the battery, but also damages the battery itself due to the high temperature generated
