Description

Technical Field

[0001] The utility model relates to a charging base. Background Art

[0002] In the prior art, a charging base generally includes a charging base housing, charging terminals (or power supply terminals) disposed in the charging base housing, and a charging cable (or power supply line) electrically connected to the charging terminals. To increase the charging speed, it is necessary to increase the charging current. Currently, the required charging current is as high as 600 A, and it may increase to 1000 A in the future. When such a large current flows through the charging cable and the charging terminals, the temperature inside the charging base housing and the temperature of the charging cable will rise sharply. To prevent the temperature from rising too much, there are two solutions in the prior art. One solution is to increase the diameter of the charging cable, but this will increase the volume and weight of the charging base product and result in a higher cost. Another solution is to install a liquid cooling module in the charging base housing to cool the charging cable and the charging terminals.
