  "textContent": "The disclosure provides an energy storage device comprising four energy units with a same rated voltage and a socket, wherein the four energy units are equally divided into two energy modules, and the socket comprises two voltage output terminals respectively connected with a positive electrode and a negative electrode of the electric energy storage device. The socket is further provided with an in-module control part for switching the connection state of two energy units in the energy modules and an inter-module control part for switching the connection state between the two energy modules. The disclosure provides an electric tool system, wherein the electric tool is provided with a plug coupled with a socket. The energy storage device can provide three output voltages, which can be matched with electric tools with different rated voltages, improves the adaptability of the electric energy storage devices, and reduces the cost.",
