A protection circuit (PCM) 141 can prevent an overvoltage or an overcurrent from being applied to the batteries 142, 143, and 144.

The batteries 142, 143, and 144 may be charged with the first charging power, the second charging power, and the third charging power that are input, and may supply power to the components or the external devices in the battery pack 100 . One or more batteries 142, 143, 144 may be provided in the battery pack 100, and the batteries 142, 143, 144 may be connected in series or in parallel.

The power output terminal 160 is connected to an external device and can output the electric power charged in the batteries 142, 143 and 144 to an external device.

For example, assuming that the third charging power is not generated in the wired charging unit 130 and the first charging power is generated in the wireless charging unit 110, the controller 170 determines that the first charging power The first charging power is applied to the batteries 142, 143 and 144 and the second charging power generated by the solar charging unit 120 is supplied to the batteries 142, 143 and 144, 144 from being applied. On the other hand, when the first charging power is not sufficient to charge the batteries 142, 143, and 144, the controller 170 simultaneously applies the first charging power and the second charging power to the batteries 142, 143, .

The controller 170 charges the batteries 142, 143, and 144 only in the wired charging mode when the most stable wired charging is possible. When the wired charging is not possible, the controller 170 uses the batteries 142 and 143 144, 144, 144 can be charged in a stable and efficient manner.

The controller 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, , 143 and 144 can be charged stably and efficiently.

The control unit 170 displays information on how the batteries 142, 143 and 144 are charged by the wired, wireless and solar systems or the charging status information of the batteries 142, 143 and 144 on the display unit 150 ). ≪ / RTI >

The battery pack outputs the charged electric power to the external device so that the external device can be easily operated or charged.

Because the battery pack can charge the battery according to various charging methods, it is possible to charge the battery easily at any place without regard to the charging method.
