The invention provides an electric energy transmission device, and the device comprises a pipeline and a cooling unit; the pipeline comprises a pipeline, a first conductive terminal and a second conductive terminal; the first conductive terminal and the second conductive terminal are tightly assembled at the two ends of the pipeline; the cooling unit is communicated with the pipeline, the pipeline of the cooling unit and the pipeline of the pipeline form a closed annular pipeline, and conductive liquid is arranged in an inner cavity of the annular pipeline. The electric energy is transmitted in the pipeline through the conductive liquid, and the conductive liquid circularly flows in the pipeline and flows through the cooling unit to realize heat exchange, so the conductive liquid can cool the first conductive terminal and the second conductive terminal while transmitting the electric energy, the cooling efficiency is improved, and a larger current can be safely borne; and the problem of complex manufacturing process of the existing power wire harness is also improved. The invention further relates to an electric automobile charging system adopting the electric energy transmission device, high-power charging of an electric automobile is safely achieved, meanwhile, the flexibility of a charging gun cable is improved, and easy charging operation is facilitated.
