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.

    本发明提供了一种电能传输装置,包括管线和冷却单元,管线包括管道和紧配于该管道两端的第一导电端子及第二导电端子,冷却单元与管道导通,冷却单元的管路与管道的管路形成一封闭的环形管路,该环形管路的内腔设有导电液体,通过导电液体在管线内传输电能,导电液体在管线内部循环流动并流经冷却单元实现热交换,使得导电液体传输电能的同时可冷却第一导电端子及第二导电端子,提高了冷却效率,可以安全地承载更大的电流,同样改善了现有功率线束制造工艺复杂的问题。还涉及了一种电动采用该电能传输装置的汽车充电系统,安全地实现对电动汽车进行大功率充电,同时改善充电枪电缆的柔性,利于轻松进行充电操作。
