Problems solved by technology
Although the process of charging, discharging and recharging repeatedly can ensure that the power of the battery is kept fully charged, it will increase the number of times the battery is charged, and the ability of the battery to store charge will decrease as the number of times of charging increases. Therefore, the use of known charging methods will eventually lead to a shortened service life of the battery
[0006] In addition, if the user continues to use the portable electronic device while the battery is being charged by the external power supply, the external power supply must also provide most of the power to the portable electronic device, and the battery will not be able to use it at this time. Get the maximum charging energy, but also cause the time required to charge it to increase

Embodiment Construction
[0022] In order to protect the battery from shortening its life due to repeated charging and discharging, the best charging method is not to overcharge the battery, so you can set an upper limit, and when the battery is charged beyond this upper limit, it will not be charged; similarly , it is also possible to set a lower limit value, and when the power of the battery is lower than the lower limit value, the battery is charged, so that the battery overcharge can be avoided. In order to make the content of the present invention clearer, the following specific examples are given as examples in which the present invention can actually be implemented.
[0023] figure 2 It is a flowchart of a charging method for a portable electronic device according to a preferred embodiment of the present invention. Please refer to figure 2 , the charging method of this embodiment includes setting a charging range to charge the battery of the portable electronic device. The portable electron...

The invention provides a method for charging a portable electronic device. When the portable electronic device is plugged into an electrical outlet, the method selects a protecting mode or a quick charge mode to charge according to the present working condition of the portable electronic device and controls the electric power of the battery to be within certain safe range. Therefore, the invention increases the electric power of the battery at the highest speed under the condition that the using effectiveness of the portable electronic device is not affected and protects the battery in order not to be overcharged, thereby prolonging the service life of the battery.
Description
technical field [0001] The present invention relates to a charging method, and in particular to a charging method for a portable electronic device. Background technique [0002] Currently, there are two power supply modes for portable electronic devices, one is provided by an external power supply, and the other is provided by a battery. Portable electronic devices emphasize mobility, and they are generally used outdoors. In such a situation where an external power supply cannot be connected, the power of the entire portable electronic device can only rely on the power installed inside it. battery to supply. It can be seen that for portable electronic devices, the battery is the most important source of power supply, and how to use the battery to provide continuous and stable power, as well as to effectively and quickly charge the battery and save charging time, is an evaluation An important basis for the performance of this portable electronic device. [0003] At present...
