Problems solved by technology

At present, the voltage platform of electric vehicles cannot increase the charging power by increasing the charging voltage due to various factors, and can only increase the charging power by increasing the charging current.
[0003] When the charging current is greatly increased to hundreds of amperes, the terminal will be required to carry a larger current. During the charging process of such a large current, the charging terminal will generate a lot of heat according to Ohm's law, so as the heat of the charging terminal continues to accumulate It will increase the temperature of the entire connected system, making the charging process very dangerous and even impossible to continue charging

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging, in particular to a power pin cooling assembly and a charging connector. Background technique [0002] With the continuous development of the new energy electric vehicle industry, the cruising range of electric vehicles has increased, and the capacity of power batteries has become larger and larger. It is necessary to increase the charging power to achieve fast charging to solve the problem of charging speed. However, the current voltage platform of electric vehicles cannot increase the charging power by increasing the charging voltage due to various factors, and can only increase the charging power by increasing the charging current. [0003] When the charging current is greatly increased to several hundred amperes, the terminal will be required to carry a larger current. During such a high-current charging process, a large amount of heat will be generated by the charging termin...
