Title:
CENTRALIZED ENERGY STORAGE CHARGING PILE
Document Type and Number:
WIPO Patent Application WO/2021/073049
Kind Code:
A1
Abstract:
A centralized energy storage charging pile, comprising high-frequency isolation conversion bidirectional or unidirectional DC/DC converters (7, 8) and DC buses (10, 11), a first connection point of the DC/DC converter (7, 8) being connected to one or more groups of energy storage devices (9) by means of an energy storage bus (6), and a second connection point being connected to the DC buses (10, 11), and further comprising high-frequency isolation conversion bidirectional or unidirectional first and second AC/DC conversion devices (2, 4). By concentrating the electric energy of the energy storage devices on the energy storage bus, and combining the electric energy of an AC power grid and the electric energy of the battery in an electric vehicle, electric energy can freely flow among the energy storage bus, the AC power grid, and the battery of the electric vehicle, reducing the impact of electric vehicle charging on the AC power grid, the battery in the vehicle can be effectively utilized and used as a type of energy storage to reversely feed power to the power grid or charge the energy storage devices, and the electric energy of the energy storage devices can be used to charge the electric vehicle or feed the power grid so as to form an integrated solution.
