Problems solved by technology
At present, because the DC power supply positive and DC power supply negative of the vehicle connector are connected to the vehicle battery through crimping cables, and the natural cooling scheme is adopted, the current carrying capacity of the DC pin of the charging connector is limited. According to the national standard documents and tests, the vehicle charging connector The existing solution has a maximum current of 250A, a voltage of 1000V, and a maximum charging power of 250kW, which cannot meet the future needs of 400kW or even higher power charging in the electric vehicle industry.

Description
technical field [0001] The invention belongs to the technical field of high-power charging, and in particular relates to a charging connector, a charging device and an electric vehicle. Background technique [0002] The continuous progress of clean energy technology has led to the continuous improvement of people's demand and requirements for high-power DC charging. [0003] For example, in the field of electric vehicles, the cruising range of electric vehicles continues to increase, and the power stored in the power batteries of electric vehicles will inevitably increase, which will inevitably put forward higher requirements for charging speed. At present, since the DC power supply positive and DC power supply negative of the vehicle connector are connected to the vehicle battery through crimping cables, and the natural cooling scheme is adopted, the current carrying capacity of the DC pin of the charging connector is limited. According to the national standard documents an...
