在具体应用中，开关单元接收到第一信号时接通充电电路单元，便携式充电装置1进入充电模式；开关单元接收到第二信号时接通放电电路单元，便携式充电装置1进入对外充电模式。在本实施例中，开关单元在接收到第一信号时接通充电电路单元，充电电路单元通过直流转交流(DC-AC)电路，将直流电转换为交流电，便携式充电装置1进入充电模式，为电池包101充电；开关单元在接收到第二信号时接通放电电路单元，放电电路单元通过直流转直流(DC-DC)电路，将直流电转换为直流电，通过第二充电设备104为外部终端设备充电，便携式充电装置1进入对外充电模式，为外部终端设备充电，其中，根据实际情况可以设置第一信号与第二信号相对或其他适用于上述开关进行闭合或者断开操作的的情况。例如，设置第一信号为强电流，第二信号可设置为与第一信号相对的弱电流。需要说明的是，本便携式充电装置1可以作为共享供电装置，放置在共享充电桩区域，便于使用者及时的取用；或者使用者随时能够通过共享充电桩对电池包进行充电。In a specific application, when the switch unit receives the first signal, the charging circuit unit is turned on, and the portable charging device 1 enters the charging mode; when the switch unit receives the second signal, the discharging circuit unit is turned on, and the portable charging device 1 enters the external charging mode. In this embodiment, the switch unit turns on the charging circuit unit when receiving the first signal, and the charging circuit unit converts direct current into alternating current through a direct current to alternating current (DC-AC) circuit, and the portable charging device 1 enters the charging mode, for The battery pack 101 is charged; the switch unit connects the discharge circuit unit when receiving the second signal, and the discharge circuit unit converts direct current to direct current through a direct current to direct current (DC-DC) circuit, and the second charging device 104 is an external terminal device Charging, the portable charging device 1 enters the external charging mode to charge the external terminal equipment. According to the actual situation, the first signal can be set to be opposite to the second signal or other conditions suitable for the above-mentioned switch to be closed or opened. For example, if the first signal is set as a strong current, the second signal can be set as a weak current relative to the first signal. It should be noted that the portable charging device 1 can be used as a shared power supply device and placed in the area of the shared charging pile, which is convenient for the user to access in time; or the user can charge the battery pack through the shared charging pile at any time.
本实施例通过利用开关的属性，实现便携式充电装置1随时的切换进入充电模式或者放电模式，有效地提高了对电动车充电的效率。也能够有效地节省使用者的时间，除了能在户外没电网的情况下对新能源车进行补充电能，还可以作为户外离网电源，供其他用电设备使用。In this embodiment, by using the property of the switch, the portable charging device 1 can be switched to the charging mode or the discharging mode at any time, which effectively improves the charging efficiency of the electric vehicle. It can also effectively save users' time. In addition to supplementing electric energy for new energy vehicles when there is no power grid outdoors, it can also be used as an outdoor off-grid power supply for other electrical equipment.
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention.
