Abstract
An energy storage battery and a control method thereof. The energy storage battery includes battery groups connected in parallel, and each battery group includes batteries connected in series. Each battery includes a charge and discharge circuit, including a storage battery, a first switch, and a second switch, and the first switch and the second switch are used to control conduction of a connection line between two batteries. The batteries are connected in series to form the battery groups, and the battery groups are connected in parallel to form the energy storage battery, such that when the energy storage battery operates, each battery independently controls the on-off of its first switch and second switch to control the conduction of connection lines between the battery and other batteries, thereby allowing each battery of the energy storage battery to be freely extended. When a certain battery has a fault, it is merely required to control the battery group including the battery and to disconnect and repair the faulty battery, thus improving the overall operation efficiency of the energy storage battery.
