Abstract
An electric energy storage device, comprising N energy units with a same rated voltage and provided with a socket, wherein the N energy units are equally divided into M energy modules. Each energy module comprises K energy units, wherein M≥2 and K≥2, and can be switched between parallel and series connection states. The disclosure also provides an electric tool system, wherein the electric tools with different rated voltages have different plugs, and the electric energy storage device outputs different voltages after connecting with the socket. The electric energy storage device with multiple output voltages can be suitable for electric energy storage devices with different rated voltages, and reduces the cost.
