Abstract

The invention provides a wireless terminal energy router and a control method and a control system thereof. The wireless terminal energy router comprises a photovoltaic interface, an alternating current grid-connected interface, a direct current bus and a wireless electric energy transmission system, one end of the direct current bus is connected with a photovoltaic module through the photovoltaic interface, and the other end of the direct current bus is connected with a power grid through the alternating current grid-connected interface; one end of the wireless electric energy transmission system is connected with the direct current bus; each user load is connected to the wireless terminal energy router through the other end of the wireless electric energy transmission system, and the photovoltaic module and / or the power grid supply power to the user loads in a wireless electric energy transmission mode. According to the invention, the difference between the power and the voltage level of the load is considered, wireless electric energy transmission is carried out on the load, accidents caused by the adoption of a wired electric energy transmission mode are avoided to a certain extent, and the safety and the reliability of power supply are greatly improved.

Description

technical field [0001] The present invention relates to the application technical field of the combination of wireless energy transmission technology and electric energy router, in particular to a wireless terminal energy router and its energy router control method and control system. Background technique [0002] In the 21st century, environmental and energy issues have increasingly become one of the prominent issues in the world, and the contradiction between economic and social sustainable development has become prominent. As a clean, pollution-free and renewable energy, electric energy has begun to play a more important role in people's production and life, as well as in the fields of industry, aerospace, and medical treatment. However, due to friction, wear and exposed wires in the currently widely used wired power transmission method, it is easy to generate contact sparks, which affects the safety and reliability of power supply, shortens the service life of electrical...
