The invention relates to a control method for electromobile energy storage, and specifically relates to a control method for a charge-discharge virtual synchronization motor for electromobile energy storage. A charge circuit used in the method is a high-frequency isolated PWM rectification circuit, the PWM rectification circuit comprises an alternating-current interface and a direct-current interface which are sequentially connected, the alternating-current interface adopts an H-bridge AC/DC rectification circuit and is used for rectifying a power grid voltage to a 600V direct-current voltage; the direct-current interface adopts an isolated DC/DC converter, and is used for converting the 600V direct-current voltage to a 48V direct-current voltage and supplying the 48V direct-current voltage to an electromobile load. The method comprises the following steps: (1) controlling the alternating-current interface by a virtual synchronization motor control policy; (2) carrying out the double-ring control of a voltage outer ring and a current inner ring on the direct-current interface. The control method is capable of reducing the influences of a charge interface and a discharge interface on a power grid, and improving the adaptability of the power grid to large-scale energy storage access; the direct-current interface adopts an isolated DC/DC converter, so that the need of rapid constant-power charge of an energy storage battery can be met.
