As shown in FIG. 16, the user can use the battery 90 of the car to connect to the adapter 10 through the DC input interface, thereby charging the battery pack connected to the adapter 10. The user can also activate the engine of the car to idle the car battery 90. Thus, the battery pack in the electrical energy system 100 can always be charged as long as the vehicle has fuel. Of course, the user can use the DC output interface of the adapter 10 to charge the battery 90 of the car to solve the problem that the car cannot be started because the battery 90 is emptied.

The DC input interface can also be constructed as a USB interface 15 or 12V interface as shown in FIG.

This allows the adapter 10 to which the battery pack is attached to be wirelessly charged when it is used as a power source. The wireless charging device can be powered by the AC power source that is connected to the adapter 10 or by the DC power supplied by the battery pack to which the adapter 10 is connected.

As an alternative, the adapter 10 also includes a wireless communication device that can be used to wirelessly communicate the adapter 10 with a battery pack, other adapters, or other wireless communication device. As a specific solution, the wireless communication device can be used as a wireless router of a local area network, which can directly access the Internet to enable other wireless communication devices in the local area network to access the Internet, and can also access through a communication device.
