ENERGY STORAGE CHARGING SYSTEM

An energy storage charging system includes an AC/DC conversion apparatus for high-frequency isolation transform which takes electricity from a power grid and supplies electricity to a load, and a DC/DC conversion apparatus for high-frequency isolation transform which supplies electricity to a load from battery discharge. In the present invention, charging is performed by converting into direct-current electric energy through the charging AC/DC, electricity may be simultaneously discharged to a load electricity—supply bus by means of a high-frequency isolation DC/DC conversion apparatus, and at the same time, an AC/DC connected with alternating current converts alternating-current electric energy into direct-current electric energy to output to the load electricity-supply bus so as to supply electricity to the load. The charging AC/DC is isolated by means of a high-frequency isolation transformer and electric energy passing through the transformer is adjusted.
