The present disclosure provides an energy storage circuit, and a control method. The energy storage circuit includes a DC/DC circuit including a primary side and a secondary side which are connected through a transformer; at least one AC/DC circuit electrically connected between the DC/DC circuit and an electrical grid; a third grid voltage detector configured to measure a grid voltage and detect an on-grid state or an off-grid state; a grid power relay; and a processor. In response to the on-grid state being detected and a grid voltage being detected abnormal, the processor is configured to turn off the grid power relay for disconnection and generate waves using a dual active bridge (DAB) topology mode; and in response to the off-grid state being detected and the grid voltage being detected normal, the processor is configured to determine whether the primary-side voltage is matched with the secondary-side voltage.

Energy storage circuit and control method thereof

A multi-source coupling system for household energy storage includes an energy gateway configured to control coupling and decoupling of different power sources; an energy storage system coupled to the energy gateway and configured to store electrical energy; and a power conversion system coupled to the energy gateway and configured to convert the different power sources into current sources or voltage sources.
