  "textContent": "A battery pack, an energy storage apparatus, and an energy storage system are provided. The energy storage apparatus includes a plurality of stacked battery packs, each battery pack including a plurality of battery cells. In two contact surfaces of two adjacent battery packs, a protective part and a first connector are disposed on one of the contact surfaces in a protruding manner, and a groove and a second connector are disposed on the other of the contact surfaces. The second connector is located in the groove, the protective part is connected to the groove, and the first connector is connected to the second connector. The energy storage apparatus can implement accurate alignment between the battery packs, thereby greatly reducing an assembly procedure and an assembly time for mounting the energy storage apparatus and improving assembly efficiency of the energy storage apparatus.",
