ENERGY STORAGE APPARATUS AND ENERGY STORAGE APPARATUS CONTROL METHOD

An energy storage apparatus includes a battery, a DC/DC conversion circuit, a controller, a first branch, and a second branch. The battery is connected to a first end of the DC/DC conversion circuit, the first branch and the second branch are connected in parallel between a first end of a power converter and a second end of the DC/DC conversion circuit, and impedance of the first branch is less than that of the second branch. A first end of a power conversion circuit is connected in parallel to a first capacitor, the controller controls, based on a difference between a voltage of the energy storage apparatus and a voltage of the power converter, the first branch and the second branch to be connected or disconnected, to implement soft-start of the energy storage apparatus or the power converter.
