Disclosed by the present invention is an energy storage charging system, comprising 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, thus adjusting the charging voltage and current of a direct current bus to an energy storage apparatus; and the power supplying DC/DC is isolated by means of the high-frequency isolation transformer and electric energy passing through the transformer is adjusted, and the power supply voltage and current for the load power supply bus are adjusted, thus achieving the goal of charging electric vehicles or other types of loads.
