Background
The energy storage system is separated from the grid-connected function, so that the energy storage system can realize alternating current-direct current switching between an energy storage power supply and a power grid, and the electric quantity is stored in the separated grid-connected function and is used for equipment for supplying power for emergency power. It should be noted that grid connection refers to that electricity consumption or power generation equipment is connected with a power grid, absorbs power of the power grid or generates power to the power grid. Off-grid means that the power utilization or generation equipment is not connected with the power grid, and the energy storage power supply provides electric energy.
Existing energy storage power supplies are provided with a plurality of output interfaces for different devices to be connected to the energy storage power supply. After a user connects at least one device to an energy storage power source via some data line or charging line, the energy storage power source may power the device. When the energy storage power supply supplies power to a plurality of devices, due to the limitation of port types and quantity of output ports of the energy storage power supply and the matching quantity of charging head types of the devices, the energy storage power supply is often required to be connected with one power strip so as to meet the requirement of common charging of different devices. The device must therefore be within a certain distance of the energy storage power source and the device must be connected to said energy storage power source by means of wires, so that the energy storage power source cannot conveniently supply at least one device outside a certain distance. More particularly, various wires are kept between at least two devices and the energy storage power supply, so that accidents of stumbling and pulling are easy to occur, and safety and convenience in using the devices and the energy storage power supply by users are not facilitated.
Furthermore, different data lines are required for different devices. Therefore, the storage and carrying of the data line is also a difficulty in headache for users. Because the data lines are of various types and are easily lost or placed everywhere, the user needs more effort to store and carry the data lines. In addition, the energy storage and devices connected by the data line circuit may also appear more cluttered.
On the other hand, the energy storage power supply is supplied to the equipment in a mode that the energy storage power supply cannot follow the walking equipment because the energy storage power supply is connected with the equipment through wires. Some devices that are only movable within a short distance can be operated by the stored energy power source, but if the device needs to expand the operating range, the stored energy power source becomes a greater work impediment.
