The multi-power input unit 110 is connected to and connected to different power sources 10, respectively, and power for charging the battery pack 20 or the battery management system (BMS) from different power sources 10 It is a configuration for receiving. 4, the multi-power input unit 110 is provided with a first power input terminal 111 for receiving photoelectrically converted DC power from a photovoltaic module and commercial power to DC power. It may be configured to include a second power input terminal 112 for receiving the DC power of the adapter. Here, the multi-power input unit 110 includes a first power input terminal 111 for receiving solar power and a second power input terminal 112 for receiving adapter power. It may further include. At this time, the preliminary power input terminal 113 may be used as a preliminary connection terminal when the connection of the first and second

power input terminals

111 and 112 is abnormal.

Different power sources 10 may be composed of a solar power supply for supplying DC power photoelectrically converted from the photovoltaic module, and an external adapter power supply for converting and supplying commercial power (AC110V or AC220V) to DC power. Alternatively, the adapter power may be implemented as a built-in smart balancing energy charging control system.

Renewable power sources may be applied. In addition, the battery pack 20 is an outdoor camping auxiliary battery device for supplying DC power or AC power to electric or electronic devices used outdoors.

The micro control unit 120 performs charging according to the rated power of the battery pack 20 by using applied charging power of different power sources 10 applied from the multi power input unit 110, but different power sources are used. This is a configuration of a control unit that performs a smart balancing control by comparing the charging power of the source 10. The microcontroller unit 120 compares the charging power of different power sources 10 to perform smart balancing control, but the smart balancing control controls charging current of different power sources 10 current control).

Alternatively, the micro control unit 120 may determine whether a predetermined condition is satisfied, and perform smart charging balancing control. The predetermined condition may include a case where the energy level, power, or energy efficiency of the renewable power source is higher than a predetermined value. For example, it may include a case where the energy level, power, or energy efficiency of a new and renewable power source satisfies a minimum of 5 W or more and is higher than 10% of the maximum power value. For example, if a renewable energy source having a maximum output of 100W is input with an energy efficiency of 10W or more and satisfies a minimum value of 5W or more, the power of commercial power can be cut off and renewable energy power can be used as an input source.

By checking the set time and the amount of charge, it is possible to flexibly switch between renewable energy sources and commercial power sources so that users can easily and conveniently charge products such as battery packs without special measures for charging. For example, the smart charge balancing control receives input from multiple power sources and cuts the power of the commercial power source (adapter power source) when the efficiency of the input of the new and renewable energy source becomes higher than 10% of the charging efficiency of the commercial power source, and the renewable energy source Charging can only proceed through. For example, when the charging efficiency of commercial power is 60Wh, the efficiency of 10% is 6W, and if a renewable energy source with a maximum output of 100W is input with an energy efficiency of 6W or more, it exceeds 10% of the charging efficiency of commercial power.

Smart balancing control can be performed with power, but when the weather is clear and the power generation of solar power is high, it is possible to perform preset smart balancing control by increasing the current of solar power and lowering the current of commercial power. That is, when charging from the outdoor activities such as camping to the battery pack 20, when the solar power and commercial power are used as a multi-power source, the weather is clear and the solar power is high in power generation efficiency. Smart balancing control can be used to reduce use and enable charging through efficient power supply through solar power supply.
