Title:
ENERGY ROUTER, CONTROL METHOD, CONTROL APPARATUS AND POWER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/041010
Kind Code:
A1
Abstract:
Disclosed in the present application are an energy router, a control method, a control apparatus and a power system. The energy router comprises: a first terminal, which is used for connecting to a positive electrode of an energy storage battery; a second terminal, a third terminal and a fourth terminal, which are used for respectively connecting to three-phase input ends of an alternating-current power grid, or respectively connecting to positive electrodes of three photovoltaic power generation modules; a fifth terminal, which is used for connecting to one of a negative electrode of the energy storage battery, a neutral wire of the alternating-current power grid and a negative electrode of a photovoltaic power generation module; and a switching module, a first end of which is connected to a rectification module, and a second end of which is respectively connected to the first terminal, the second terminal, the third terminal and the fourth terminal and is used for controlling, according to a control instruction, whether to switch on the first terminal, the second terminal, the third terminal and the fourth terminal. The present application can realize the integration of a photovoltaic DC/DC conversion function, an energy storage DC/DC conversion function and a power grid conversion function by means of the same hardware, thereby reducing the hardware cost.
