[0002] In order to improve the energy conservation and environmental protection effects, the proportion of electric vehicles in life is increasing at present. Electric vehicles need electricity as energy during use and use antifreeze to improve the use safety. Therefore, it is necessary to replenish electricity and antifreeze in time. The battery connectors that can quickly charge the battery pack and the liquid-cooling connectors for replenishing antifreeze have been popularized in the electric vehicle industry.
[0003] In the existing power exchange stations, usually one electrical connector and two liquid-cooling connectors are arranged in each charging device for charging and replenishing liquid.
