Electronic devices implemented in the form of multimedia devices are being applied variously in terms of hardware and software in order to implement complex functions.

In order to carry such a multimedia electronic device for a long time, a high-capacity battery pack is essential, and a battery pack can be charged and discharged, so that it can be used repeatedly. Particularly, among electronic devices, a mobile phone is carried from the outside for a long period of time, and continuous wave reception and transmission are performed. In addition to calls, complicated data processing such as graphic calculation or file reproduction becomes common, Therefore, when a mobile electronic device such as a mobile phone having a large power consumption is used outside, a user has a charging adapter to discharge the battery pack of the electronic device, The battery pack must be charged by connecting the electronic device.

However, in an environment in which there is no external power source, the battery pack can not be charged through the adapter, so that the electronic device can not be used for a long time. In addition, even in the case of having a spare battery pack, since the user has to close the used electronic device in order to replace the battery pack, it is inevitable to end the program being executed in the electronic device.

Therefore, there is a high need for a technology that can use an electronic device for a long time from the outside.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems of the prior art and the technical problems required from the past.

In one specific example, the main battery pack may be an embedded battery pack built in the main body of the electronic device. Although the built-in battery pack can have a high charging efficiency in a short time, it can not be replaced with an extra battery pack when discharged from the outside. However, even in an environment where there is no external power supply, , The auxiliary battery pack can serve as a spare battery pack.

Alternatively, the main battery pack may be a replaceable battery pack that can be attached to and detached from the main body of the electronic apparatus. At this time, the main battery pack may have the same structure as the auxiliary battery pack.
