As another example, assuming that the third charging power is not generated by the wired charging unit 130 and the first charging power is generated by the wireless charging unit 110, the controller 170 determines that the first charging power is When it is sufficient to charge (142, 143, 144), the first charging power is applied to the batteries 142, 143, 144, and the second charging power generated by the solar charging unit 120 is the batteries 142, 143, 144) can be blocked. On the other hand, when the first charging power is not sufficient to charge the batteries 142, 143, and 144, the controller 170 applies the first charging power and the second charging power to the batteries 142, 143, 144 at the same time. I can make it.

In this way, when the most stable wired charging is possible, the controller 170 charges the batteries 142, 143, and 144 only by the wired charging method, and when wired charging is not possible, the battery 142, 143 By charging, 144, it is possible to stably and efficiently charge the batteries 142, 143, 144.

In addition, the control unit 170 selects the type of charging power applied to the batteries 142, 143, and 144 according to whether the charging power is sufficient to charge the batteries 142, 143, and 144, so that the battery 142 , 143, 144) can be charged stably and efficiently.

The controller 170 displays information on whether the batteries 142, 143, and 144 are charged by any of wired, wireless, and solar methods, or information on the charging status of the batteries 142, 143, 144, and the display unit 150 ) Can be displayed.

The battery pack can easily operate or charge an external device by outputting the charged power to an external device.

Since the battery pack can charge the battery according to various charging methods, it is possible to easily charge the battery in any place regardless of the charging method.

The battery pack can charge the battery stably and efficiently by controlling the charging method differently depending on whether wired charging is possible.

The battery pack may provide information to the user so as to easily grasp the current state of charge of the battery as well as whether the battery is being charged by any of wired, wireless, and solar methods.

Since the battery pack allows the user to operate a desired external device using the battery of the battery pack, it is possible to freely use the desired external device even in a place where separate power supply cannot be provided, such as a remote area.

The power output terminal 160 is formed on one side of the battery pack 101, and may output power charged in the battery to an external device connected to the power output terminal 160.

The sealing cover 180 may be inserted into and coupled to the wired power input terminal 132, the power output terminal 160, and the battery accommodating groove 223. Accordingly, when the sealing cover 180 is inserted and coupled, moisture or dust existing outside cannot enter the inside of the auxiliary battery charging device 100. When the user wants to use the wired power input terminal 132, the power output terminal 160, and the battery receiving groove 223, the sealing cover 180 is attached to the wired power input terminal 132, the power output terminal 160. And, it can be used by extracting from the battery receiving groove 223.

The battery accommodating groove 321 is formed on one side of the battery pack 101, and the battery 142 may be inserted.

The shielding member may include a magnetic material to more effectively form a magnetic path generated from the receiving coil 111, and an eddy current reducing member formed in a mesh shape to reduce external emission of the magnetic field. have. Here, the magnetic material serves to improve efficiency by forming a magnetic path and at the same time serves to prevent the magnetic field from escaping to the outside of the battery pack 101. The eddy current reducing member finally blocks a part of the magnetic field exiting the magnetic body. As a result, the magnetic material and the eddy current reducing member may have a form in which two plates are stacked so that their main surfaces face each other.
