Description

Technical Field

[0001] The utility model relates to the field of new energy vehicle charging, and specifically to a mobile charging station. Background Art

[0002] With the development of the economy and the progress of society, new energy vehicles have become increasingly popular. Whether in the self-use or car rental market, the proportion of new energy vehicles is increasing. Therefore, the demand for charging piles is also increasing.

[0003] Existing charging piles are all installed at fixed locations and are not movable. However, for some scenarios where it is inconvenient to install charging piles at fixed locations, such as self-owned vehicles without fixed parking spaces, parking lots of homestays and hotels, scenic area parking lots, etc., in some of these scenarios, it is difficult to install charging piles at fixed locations, or there are limited charging piles installed at fixed locations, or even the parking spaces themselves are in short supply. In these scenarios, there will be many charging difficulties for new energy vehicles.

[0004] In reality, some new energy vehicles come with a simple charging gun with a 220V plug board. However, this charging method is slow on the one hand, and on the other hand, it is difficult to manage the private pulling of wires, and it is easy to cause safety problems such as fires. However, in the above scenarios, if dedicated charging piles are arranged, they are often restricted by the grid capacity. Generally, dedicated charging piles require a power of 380V and above 60kW, resulting in the inability to obtain mains power access. If an application is made to the power department to increase the power supply capacity, the construction cost and construction period are unacceptable. In the industry, there are technical samples of mobile charging piles using autonomous driving technology, but such samples have immature autonomous driving technology and low alignment accuracy, resulting in unusability, and cannot be used in places without GPS signals such as basements, and the cost is extremely high and cannot be commercially implemented.

[0005] Existing charging piles installed at fixed locations often cannot meet the charging needs of many new energy vehicles in the above scenarios, and private pulling of charging guns is not only slow in charging, but also prone to management and safety problems.

[0074] As Figures 1 to 4 shown, the charging station box body 1 of the present utility model is a cuboid structure, with a mobile roller group 2 at the bottom and a charging port 3 on the side wall. It can be moved by the assistance of a handle 5 or controlled by an external mobile control device 4.

[0075] The charging station box body 1 is provided with a charging port 3. The charging port 3 is connected to a number of nodes after being connected in series with an AC-DC converter 6. Each node is respectively connected to a charging gun and a DC-DC converter. Each DC-DC converter is connected to the battery pack 9, and the battery pack 9 is connected to a motor 11. The mobile roller group 2 is arranged at the bottom of the charging station box body 1. The mobile roller group 2 includes a number of external supporting universal wheels 15, at least one universal power steering wheel 16 and a physical brake lever 17. The external supporting universal wheels 15 are located around the bottom of the charging station box body 1, and the universal power steering wheel 16 is located at the center of the bottom of the charging station box body 1.

To ensure safety, the moving speed of the overall charging station box 1 is generally less than 10KM / h, and the moving up and down slope is less than 30°. The above specification parameters can be adjusted according to actual requirements. With the above system, a movable new energy vehicle charging station can be realized, so as to flexibly provide charging services for new energy vehicles that cannot be charged at parking spaces. Moreover, when charging the charging station, the charging can be appropriately carried out at the valley value of the electricity price, so as to further save energy and improve economic benefits.

[0081] The mobile charging station of the present utility model is a system composed of an energy storage battery pack, a charge and discharge conversion circuit, a mobile chassis, and overall control, which realizes a single-person operable system that does not require grid transformation, does not require a fixed installation position, and can also charge large-capacity electric vehicles under road surface conditions.
