Description

Technical Field

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

[0002] In recent years, new energy electric vehicles have been rapidly popularized, and the charging piles for charging and extending the range of electric vehicles are also constantly developing and being built. Each city is quickly deploying charging piles, bringing great convenience to new energy electric vehicle users. Currently, common charging piles rely on the power grid to convert alternating current from the power grid into direct current and quickly charge the batteries of new energy electric vehicles. In this process, the charging pile is similar to an electric energy converter, converting alternating current into direct current and high voltage into low voltage. The charging efficiency of such charging piles is generally low. If a power failure occurs in the power grid, such charging piles will not be able to work.

[0003] Therefore, newly developed charging piles are internally equipped with battery packs, which can input and store a certain amount of electricity from the power grid. New energy electric vehicle users can charge the batteries of new energy electric vehicles through the battery packs via electric guns, which can improve the charging efficiency and solve the charging problem during power grid outages. However, common charging piles are configured with a single battery pack, and charging and discharging cannot be carried out simultaneously. Only the charging mode or the discharging mode can be carried out within the same time period. Generally, the battery pack is charged through the power grid at night, and all are converted to the discharging mode during the day to charge new energy electric vehicles through electric guns. When the charging pile is in the charging mode, new energy users cannot use it, resulting in inconvenience in use and reduced usage 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 existing technology is installed in the charging pile, which is not convenient for rotation charging. The temperature of the single battery pack accumulates over time, and natural cooling is mostly used, posing a safety hazard. Summary of the Invention

[0046] As Figure 2 、 Figure 3 、 Figure 6 and Figure 8As shown, in some embodiments, the electricity storage body 4 includes four that are circumferentially and evenly distributed outside the central axis 51. Among them, two spaced-apart electricity storage bodies 4 are the first electricity storage bodies 4a, and the other two spaced-apart charging bodies are the second electricity storage bodies 4b. The top base 2 is provided with two discharge terminals 22 that are symmetrically arranged along the transverse direction outside the central axis 51, and the bottom base 1 is provided with two charging terminals 12 that are symmetrically arranged along the longitudinal direction outside the central axis 51.

While the adjustment motor drives the carrier 5 to rotate, each of the electricity storage bodies 4 rotates automatically under the meshing connection of the internal gear ring 31 and the external gear ring 41 to adjust the circumferential angle. With the above structure, different sides of the electricity storage body 4 can face outwards, which can improve the heat dissipation efficiency.
