Description

Technical Field

[0001] The present invention relates to the technical field of energy storage and charging, and in particular to an integrated charging pile with energy storage. Background Art

[0002] In recent years, new energy electric vehicles have been rapidly promoted, and charging piles for electric vehicles and electric vehicles are also constantly developing and building. Various cities are rapidly deploying charging piles, which brings great convenience to new energy electric vehicle users. At present, common charging piles rely on the power grid to convert the AC power of the power grid into DC power, and quickly charge the batteries of new energy electric vehicles. In this process, the charging pile is similar to an energy converter, which converts AC power into DC power and high voltage into low voltage. The charging efficiency of this type of charging pile is generally low. If there is a power failure in the power grid, this type of charging pile will not work.

[0003] To this end, the newly developed charging pile is equipped with a battery pack that can store a certain amount of electricity input from the power grid. New energy electric vehicle users can charge the battery of the new energy electric vehicle through the battery pack through the electric gun, which can improve the charging efficiency and solve the charging problem when the power grid is out of power. However, common charging piles are equipped with a single battery pack, and charging and discharging cannot be carried out at the same time. Only charging conditions or discharging conditions can be carried out in the same time period. Generally, the battery pack is charged through the power grid at night, and all are converted to discharging conditions during the day. The new energy electric vehicle is charged through the electric gun. New energy users cannot use it during the charging condition of the charging pile, causing inconvenience and reducing efficiency. Moreover, during the long-term charging process of the battery pack, the battery will heat up and the temperature will rise. The single battery pack of the prior art is installed in the charging pile, which is not convenient for rotation charging. The temperature of a single battery pack accumulates over a long period of time, and natural heat dissipation is mostly used, which poses a safety hazard. Summary of the invention

[0048] During implementation, the electricity storage body 4 includes a plurality of storage batteries connected in series vertically, the discharge electrode 42 is arranged at the uppermost end and connected to each storage battery, the charging electrode 43 is arranged at the lowermost end and connected to each storage battery, and the charging terminal 12 / discharging terminal 22 includes a vertically arranged metal guide column and a metal end cap, the metal guide column is electrically connected to the charging interface 11 / discharging interface 21, the rear end of the metal end cap is movably mounted on the guide column, and the guide column is provided with an elastic component that applies an elastic outward thrust to the metal end cap so that the metal end cap is elastically pressed onto the charging electrode 43 / discharging electrode 42.
