Abstract
Description
Technical Field
[0001] This invention relates to a charging stand. Background Technology
[0002] In existing technologies, charging docks typically include a charging dock housing, charging terminals (or power terminals) housed within the housing, and a charging cable (or power cord) electrically connected to the charging terminals. To increase charging speed, the charging current needs to be increased; currently, the required charging current is as high as 600A, and may increase to 1000A in the future. When this large current flows through the charging cable and charging terminals, it causes a rapid rise in temperature inside the charging dock housing and in the charging cable itself. To prevent excessive temperature rise, existing technologies employ two solutions. One solution is to increase the diameter of the charging cable, but this increases the size and weight of the charging dock and leads to higher costs. The other solution is to install a liquid cooling module within the charging dock housing to cool the charging cable and charging terminals.
