[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Figure 1 A schematic diagram of the overall structure of a mobile charging system for an electric vehicle according to one embodiment of this application is shown, as follows. Figure 1 As shown, the mobile charging system for electric vehicles includes multiple charging service areas 1, charging base stations 2, and logistics vehicles 3. The charging base stations 2 are deployed based on the distances between the multiple charging service areas 1, shortening the distance between them and each charging service area 1 and reducing deployment time. Both the charging service areas 1 and the charging base stations 2 can be set up according to actual needs, and are not limited to... Figure 1 One or more shown in the diagram. Combined Figure 2 The diagram illustrates a charging service area of ​​a mobile charging system for electric vehicles according to a specific embodiment of this application. The charging service area 1 is typically deployed in a ground-level or underground parking lot, containing several parking spaces. These locations are where electric vehicles are concentrated, and using them as charging service areas allows for precise charging services to a large number of electric vehicles. The relatively enclosed space of the parking lot is easy to manage, which is beneficial for the operation of the charging robot and the layout of the charging equipment. It also allows users to charge while parking, improving the accessibility and convenience of the charging service. Multiple mobile charging piles 4 and charging robots 5 are installed within the charging service area 1. The charging robot 5 can move within the charging service area 1, and its top is equipped with a detachable mobile charging pile 4. When a vehicle waiting to be charged in a parking space 11 within the charging service area 1 has a charging need, the charging robot 5 transports the mobile charging pile 4 to the side of the vehicle, enabling immediate charging upon stopping. The logistics vehicle 3 is responsible for transporting the mobile charging pile 4 between the charging service area 1 and the charging base station 2. That is, when the mobile charging pile 4 is low on power, the logistics vehicle 3 can transport the mobile charging pile 4 to the charging base station 2 to replenish its power. In another embodiment, the logistics vehicle 3 can also allocate the mobile charging pile 4 in the current charging service area 1 to the charging robot 5 in other charging service areas to ensure the efficient flow of charging resources.

[0023] In some specific embodiments, fixed charging piles 6 may also be installed within the charging service area 1, enriching the charging methods of the charging system. Fixed charging piles can provide services for users who do not have high requirements for charging time and prefer traditional charging methods. They complement mobile charging piles and charging robots, meeting the diverse charging needs of different users and further improving the applicability and compatibility of the entire charging system.

[0024] Figure 3 A schematic diagram of a logistics vehicle and a charging robot according to a specific embodiment of this application is shown, such as... Figure 3 As shown, the logistics vehicle 3 can accommodate one or more mobile charging piles 4, and is equipped with a lifting mechanism (in one embodiment, the specific logistics vehicle and lifting structure can be found in the applicant's previously published Chinese patent CN208515455U: A transport frame and power delivery vehicle for mobile charging piles). This mechanism can unload the mobile charging piles 4 from the charging robot 5 and load them into the cargo compartment of the logistics vehicle 3 using a robotic arm or lifting platform. The specific process is as follows: after the logistics vehicle 3 enters the charging service area 1, the lifting mechanism accurately positions the mobile charging pile 4 on top of the charging robot 5, completes the grabbing, and transfers it into the vehicle; subsequently, the logistics vehicle 3 transports the mobile charging pile 4 to the charging base station 2 for charging, or transfers it to the charging robot 5 in other charging service areas 1. This process is fully automated, requiring no manual intervention, significantly improving transfer efficiency and safety.

[0025] In specific embodiments, charging base station 2 can be a fixed-area base station or a mobile-deployable base station, increasing the flexibility and adaptability of the charging base station. Fixed-area base stations can provide stable charging support for relatively fixed charging service areas in the surrounding area, while mobile-deployable base stations can be flexibly deployed to different locations according to actual needs, such as temporary event sites, areas where charging demand suddenly increases, etc., to meet charging needs in special circumstances in a timely manner, and improve the emergency response capability and resource allocation capability of the entire charging system.

[0026] Figure 4 A schematic diagram of a mobile deployment base station container according to a specific embodiment of this application is shown, such as... Figure 4 As shown, the mobile deployment base station 2 adopts a container design, with multiple charging stations inside, which can charge multiple mobile charging piles 4 simultaneously. In some preferred embodiments, solar panels or wind power generation equipment can be installed on the roof around the container and electrically connected to the energy storage module 21 to convert solar or wind energy into electrical energy and store it in the energy storage module 21. The energy storage module 21 is connected to the external power grid or distributed energy (such as solar or wind power generation equipment) through a charging interface to achieve multi-energy complementary power supply. The container is also equipped with heat dissipation mechanisms (such as fans) and monitoring modules (such as temperature and humidity sensors, cameras, etc.) to regulate the internal environment in real time and prevent the energy storage module 21 from overheating. Fully charged mobile charging piles 4 can be quickly deployed to various charging service areas 1 by logistics vehicles 3, forming a closed loop of "charging-transfer-recharging".

[0027] In a specific embodiment, the energy storage module 21 of the charging base station 2 charges the mobile charging pile 4 by reserving electricity through night valley electricity and solar panels, which can greatly reduce operating costs, save electricity bills through peak and valley electricity price difference, enhance market competitiveness, optimize power grid utilization, balance power grid load, reduce peak power supply pressure, reduce power grid construction cost, at the same time, improve charging stability, ensure continuous charging when the power grid is abnormal, protect vehicle battery and charging equipment, in addition, enhance the flexibility and adaptability of the system, make the charging service not limited by area and scene, and expand the application range. The logistics vehicle 3 takes the mobile charging pile 4 charged by the charging base station 2 back to the parking lot, so as to ensure uninterrupted charging service. In addition, when the power supply of the power grid is tight, the energy storage module 21 can independently supply power to the charging station, thereby relieving the pressure of the power grid.

[0028] The electric vehicle mobile charging system of the utility model integrates various innovative designs: the charging robot cooperates with the mobile charging pile to realize flexible charging, breaks the limitation of fixed charging piles, and improves the convenience of user charging; the fixed charging pile and the mobile charging method are complementary, and meet diversified needs. The diversified design of the charging base station, especially the movable deployment base station, enhances the mobility and emergency response capability of the system. The energy storage module combines renewable energy and valley price electricity utilization, not only reduces operating costs and optimizes power grid utilization, but also improves charging stability. The logistics vehicle and the lifting mechanism ensure the efficient circulation of the mobile charging pile, the heat dissipation and monitoring module ensures the stable and safe operation of the system, and the whole promotes the intelligentization, high efficiency and sustainable development of the electric vehicle charging industry.

[0029] Although the principle of the utility model is described in detail above in combination with the preferred embodiments of the utility model, those skilled in the art should understand that the above-mentioned embodiments are only an illustrative implementation of the utility model, and not a limitation on the scope of the utility model. The details in the embodiments do not constitute a limitation on the scope of the utility model, and any obvious changes based on the technical solutions of the utility model, such as simple replacement, etc., fall within the scope of protection of the utility model.
