Intelligent hybrid energy storage and power supply terminal

Abstract

The invention provides an intelligent hybrid energy storage and power supply terminal. The intelligent hybrid energy storage and power supply terminal comprises a controller, a direct current power driving board, a first sampling unit, a first input interface and an electrical selector switch, wherein the first input interface is used for being connected with an external direct current input; the first sampling unit is used for sampling the direct current input and transmitting the sampled information to the controller; the controller obtains a direct current input type according to the sampled information and then controls the direct current power driving board to be adjusted into a corresponding function to store the direct current input into an energy storage unit; and the controller also controls the electrical selector switch to enable the electrical selector switch to selectively connect a domestic electrical side and an alternating current grid side, so that the electric energy stored by the energy storage unit can supply power for the domestic electrical side, or the alternating current grid side can supply power for the energy storage unit to be stored.

Description

technical field [0001] The invention belongs to the field of electric equipment, and in particular relates to a power terminal device capable of storing electric energy and outputting the stored electric energy for power supply. Background technique [0002] With the development of society, human beings' demand for energy is getting higher and higher. And because the consumption of fossil energy will have a fatal impact on the environment, therefore, the human desire for clean energy is becoming stronger and stronger. Common clean energy sources include wind energy, solar energy, and geothermal energy. [0003] However, for the actual collection of clean energy, there are more or less disadvantages. For example, wind power generation is unstable and cannot be connected to the grid in time; or wind and solar energy in a certain area is excessive and cannot be exported to the user's power consumption area. [0004] In addition, for the site selection of geothermal energy, w...

[0008] Or, it is a device that can be used on the Internet but cannot store electrical energy. As disclosed in Chinese patent applications No. 200910180542 and 201520838918, it can only realize networking of electrical equipment, data collection, and simple communication, but cannot store energy.

For this kind of equipment, first of all, its charge and discharge circuit has low efficiency, which reduces the conversion efficiency of solar energy; secondly, it needs a separate computer to connect to the Internet, the overall power consumption of the system is high, the structure is redundant, and the volume is large. power may not guarantee the normal use of the computer

[0009] Moreover, the exemplary systems mentioned above can only be connected to solar energy, do not support other clean energy sources that can be collected, have a single choice of energy supply, and consume a lot of power to maintain their own system
