Description

Technical Field

[0001] The present invention relates to the technical field of new energy charging stations, and in particular to an automatic charging station based on an energy storage container. Background Art

[0002] With the continuous development of new energy technology, in order to meet the needs of environmental protection and energy structure transformation, reduce the use of traditional fuels and reduce carbon emissions, new energy models have emerged. Among them, electric new energy vehicles have been widely recognized by the market due to their advantages of low emissions and high energy utilization. However, due to the limitations of the current battery technology level, new energy vehicles in stores usually have shortcomings such as long charging time. In order to solve the problem of long charging time of electric new energy vehicles, the charging power of electric new energy vehicles is usually increased to shorten the charging time of electric new energy vehicles.

[0003] For example, a patent document with publication number CN111605422A discloses a moisture-proof wall-mounted high-power charging pile for new energy vehicles, including a main body box, in which an AC-DC power module, a fuse, a surge protector, a relay and a charging protector are arranged. The output port of the AC-DC power module is electrically connected to the input port of the fuse through a first connecting line. For the moisture-proof wall-mounted high-power charging pile for new energy vehicles, users fix the moisture-proof wall-mounted high-power charging pile for new energy vehicles on the wall through a fixing block, which saves floor space and is convenient for users to use. The main body box is sealed with a sealing strip to prevent external humid air from entering the main body box and affecting the normal use of the charging pile. A reset device is composed of a spring and a telescopic rod to facilitate users to unplug the charging plug. The charging new energy vehicle is protected by a surge protector to prevent damage to the new energy vehicle caused by unstable current.

[0004] Although the above technical solution can realize high-power charging of new energy vehicles, as the charging power increases, the diameter of the charging cable will also increase accordingly. In order to avoid the excessive temperature of the charging plug and the cable during high-power charging, it is usually necessary to configure a cooling system in the cable to cool the charging plug and the cable, which greatly increases the diameter and weight of the cable, causing the cable to become more bulky as a whole, increasing the difficulty of manually moving the charging plug, and making it inconvenient to connect to the new energy vehicle through the charging plug and charge it. Summary of the invention
