[0023] In order to make the purpose, technical scheme and advantages of the utility model clearer, the following will combine the specific embodiments of the utility model and the corresponding drawings to make a clear and complete description of the technical scheme of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, but not all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor belong to the protection scope of the utility model.
[0024] The technical solutions of the embodiments provided by the utility model are described in detail below with reference to the drawings.
[0025] The utility model discloses an embodiment provides a new energy vehicle charging station, like Figure 1 As shown, the new energy vehicle charging station comprises a transformer, a distribution box, an energy storage battery, a photovoltaic converter, a solar panel, a charging converter, a direct charging pile and a double-gun charging pile.
[0026] Specifically, the input side of the transformer is used to connect the power grid, and the transformer is used to convert the high voltage of the power grid into a low voltage that can be used for charging the new energy vehicle. The output side of the transformer is connected to the alternating current side of the charging converter through the distribution box. The distribution box is used to realize power distribution. The direct current side of the charging converter is connected to the energy storage battery, the photovoltaic converter and the direct charging pile respectively. The charging converter is used to realize the conversion between alternating current and direct current. The solar panel is connected to the photovoltaic converter. The photovoltaic converter is used to step up the power generated by the solar panel. The direct charging pile comprises a super charging pile and a fast charging pile. The double-gun charging pile is connected to the distribution box. Among them, the super charging pile can provide high-voltage and high-current power to quickly charge the new energy vehicle in a short time. The fast charging pile can quickly charge the new energy vehicle. The double-gun charging pile can simultaneously charge two new energy vehicles slowly to meet the demand of low-power vehicle models such as hybrid vehicles. In addition, a ground lock is arranged on the parking space corresponding to each charging pile. When the charging pile is not used, the corresponding ground lock is raised to prevent the uncharged vehicle from occupying the charging parking space.
[0027] In this way, when the charging station is in a low charging peak period, the charging piles are less used, and the transformer has a remaining capacity. The energy storage battery can be charged by the transformer, the capacity of the transformer is fully utilized, and the utilization rate of the transformer is improved. When the charging station is in a high charging peak period, the charging piles can be powered by the energy storage battery and the solar panel, the virtual capacity expansion of the transformer is realized, and the safe operation of the transformer is ensured. Without the need to set a large-capacity transformer, the charging demand can be met, and the equipment cost of the charging station is reduced.
[0028] In summary, in the new energy vehicle charging station of the embodiment, by arranging the energy storage battery, the photovoltaic converter and the solar panel, the virtual capacity expansion of the transformer can be realized to meet the charging demand in the high charging peak period, the utilization rate of the transformer is improved, and the operation cost of the charging station is reduced.

The distribution box is connected with five charging piles, one V2G charging pile with a maximum power of 15kW and four double-gun charging piles with a maximum power of 40kW, and corresponds to nine parking spaces. In this way, the new energy vehicle charging station has fourteen parking spaces, supports five high-power fast charging spaces and nine low-power fast charging spaces, the maximum output power of the photovoltaic is 50kW, the maximum output power of the energy storage is 332kW, which is equivalent to increasing the capacity of the transformer (315kW) by 382kW, and the theoretical maximum output power can reach 697kW, which can simultaneously serve the charging demand of fourteen vehicles and provide better charging speed.
