Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicle charging, and in particular to a method and system for charging an electric vehicle. Background Art

[0002] With the vigorous development of the new energy industry, electric vehicles have gradually emerged and become popular as an emerging force. However, compared with traditional fuel vehicles, electric vehicles have a relatively short range, which puts high demands on the popularity and coverage of charging facilities. Currently, commonly used charging facilities mainly include large charging stations, outdoor charging piles, community charging piles, and public parking lot charging piles. These charging piles are generally fixed on the ground or wall. The input end is directly connected to the AC power grid, and the output end is equipped with a charging plug, which can charge various types of electric vehicles according to different voltage levels. According to the installation method, it can be divided into floor-standing type and wall-mounted type, which are suitable for different parking space scenarios.

[0003] However, traditional fixed charging piles have many problems that are difficult to overcome:

[0004] Installation and coverage issues: Installation and transformation are difficult, and the coverage rate is low. Due to the complex projects such as power grid line transformation, the installation of charging piles in some areas, especially old communities, faces many difficulties, resulting in the overall coverage rate being unable to meet the growing charging needs of electric vehicles.

[0005] Location limitations: The location is fixed, and users need to drive to the designated charging location, which limits the convenience of charging to a certain extent. Especially when there is a sudden demand for charging and there are no fixed charging piles nearby, it is difficult to quickly solve the charging problem.

[0006] Grid pressure: Charging piles require a large power source and high grid capacity, especially DC fast charging piles, which can reach tens or even hundreds of kW, which will put great pressure on the grid. In residential parking lots, due to power capacity limitations, only AC slow charging piles can be installed, which cannot meet the needs of all users and are even difficult to install in old communities.

[0007] Waiting in queues: Public charging stations have long queues during peak usage periods, affecting users’ charging experience and time arrangements.

[0008] Some existing mobile charging piles use a charging car mode that integrates the charging pile and the car, and set up a management background. They are mainly used in small areas such as community parking lots and shopping mall parking lots, and there are a series of disadvantages:

[0009] Limited scope of application: Charging vehicles have limited transportation distance and small application scope. They cannot be promoted and used in a wider area and cannot meet the charging needs of long-distance travel or remote areas.

[0010] High cost: It is difficult to establish a dedicated charging network in residential areas or shopping malls, resulting in high storage costs for charging vehicles, which to some extent limits the large-scale application of this model.

[0011] Inconvenient scheduling and management: The charging vehicle is not equipped with a positioning device. The management background determines the charging address through the parking space number and other information uploaded by the client. The scheduling method is simple and it is easy to find the charging vehicle, which brings inconvenience to the recycling, maintenance and management of the charging vehicle.

[0012] Performance defects: The charging vehicle uses a series-connected lithium battery pack. When a problem occurs in one string, the charging vehicle will not be able to work normally and may even be scrapped. It cannot provide a constant charging current and cannot meet the international standards for electric vehicle charging.

[0013] In summary, the existing charging technologies and facilities are unable to fully meet the growing charging needs of electric vehicles, and innovative charging methods and systems are urgently needed to solve these problems. Summary of the invention

[0014] In order to solve the above technical problems existing in the prior art, the present invention proposes a charging method and system for an electric vehicle to solve the above technical problems.

[0015] According to a first aspect of the present invention, a charging method for an electric vehicle is provided, comprising:

[0016] S1: In response to receiving a charging demand from a client, analyzing and determining a service area of ​​a vehicle to be charged;

[0017] S2: Based on the configuration of mobile charging piles and charging robots in the business area, the platform allocates charging resources according to charging demand and charging priority, including:

[0018] S21: In response to the availability of mobile charging piles and charging robots in the business area, the platform sends a charging work order to the charger in the business area, controls the charging robot to carry the mobile charging pile to the location of the vehicle to be charged, and the charger plugs in the gun and starts charging;

[0019] S22: In response to the lack of available charging resources in the business area, the platform sends a charging work order to the power delivery personnel of the logistics vehicle, and pushes the mobile charging piles of the available charging base stations around the logistics vehicle according to the distance. The power delivery personnel go to the charging base station to load the mobile charging pile and deliver it to the location of the vehicle to be charged according to the prompt of the platform, and then plug in the gun to start charging;

[0020] S22 also includes that after the platform receives the charging work order, it analyzes the charging resources in other business areas around the business area of ​​the vehicle to be charged, and in response to the existence of available charging resources in other business areas and the dispatch distance of the logistics vehicle is less than the distance to the charging base station for dispatching mobile charging piles, the charging work order is sent to the logistics vehicle and other business areas, and the logistics vehicle is dispatched to other business areas to load the available mobile charging piles from the charging robot and deliver them to the location of the vehicle to be charged, and then plug in the gun to start charging.

[0021] In some specific embodiments, the charging demand includes vehicle model, vehicle location information, remaining power information and expected charging amount. The platform dispatches the mobile charging pile according to the remaining power information, expected charging amount and available power of the mobile charging pile; the expected charging amount is calculated based on the charging target power submitted by the user and the current remaining power of the vehicle; if the user does not submit a specific charging target, the expected charging amount is estimated based on the battery capacity of the vehicle model and the historical charging record. By considering the vehicle model, vehicle location information, remaining power information and expected charging amount, a customized charging solution can be provided for each user, and the platform can accurately dispatch mobile charging piles to meet the charging needs of different electric vehicles. According to the charging target submitted by the user and the current remaining power, the system can automatically calculate the expected charging amount. If the user does not provide a specific charging target, the system calculates the expected charging amount based on the electric vehicle type and historical data to ensure that the charging demand can be accurately identified and met; even if the user does not clearly state the charging demand, the system can still intelligently calculate the charging amount, avoiding scheduling errors caused by manual input of incomplete information.

[0022] In some specific embodiments, the charging resources deployed in the business area are specifically multiple mobile charging piles and charging robots. The charging robots can be detachably equipped with mobile charging piles. In response to the charging work order for cross-regional scheduling issued by the platform, the logistics vehicle arrives at the scheduling area and cooperates with the charging robot to transfer the mobile charging pile carried by the charging robot to the logistics vehicle, and distributes it to the business area with charging needs for charging operations according to the information of the charging work order. The design of separating mobile charging piles and charging robots makes the deployment of charging resources more flexible and more adaptable, and significantly improves resource utilization efficiency and system expansion capabilities. This design not only meets the needs of diverse scenarios, but also shows significant advantages in equipment cost, maintenance convenience and cross-regional scheduling efficiency, providing a solid technical foundation for the efficient operation of electric vehicle charging systems.

[0023] In some specific embodiments, in response to the current power of the available mobile charging piles in the current business area not meeting the expected charging demand, the platform calculates the available charging time based on the current power of the mobile charging piles, and dispatches other mobile charging piles in the current business area or dispatches logistics vehicles to deliver electricity from the nearest business area or charging base station to the location of the vehicle to be charged within the available charging time of the current mobile charging piles, and continues to complete the remaining charging tasks. When the existing mobile charging piles are insufficient in power, the platform calculates the available charging time and dispatches logistics vehicles for subsequent charging through the continuous charging mechanism to ensure that the charging task will not be interrupted. This method effectively solves the problem of insufficient power in the charging piles, ensures the continuity of charging through relay charging, and improves the reliability of the charging service.

[0024] In some specific embodiments, the platform dynamically adjusts the allocation of charging resources based on the following rules: the distance between the vehicle to be charged and the mobile charging pile, whether the current power of the mobile charging pile meets the expected charging amount of the vehicle to be charged, the use status of the mobile charging pile and the idle time after completing the current task, the charging urgency of the vehicle to be charged, and the waiting time of other scheduled charging tasks. Based on multiple factors (such as the distance between the charging pile and the vehicle, the power of the charging pile, the charging urgency, etc.), the platform can dynamically adjust the allocation of charging resources to give priority to the completion of high-priority charging needs; through intelligent adjustment of multiple factors, the platform can optimize the scheduling of charging resources in real time, avoid waste of resources and meet the needs of vehicles in urgent need of charging.

[0025] In some specific embodiments, the platform dynamically optimizes the deployment of charging resources based on real-time data, including: predicting future fluctuations in charging demand in the business area based on real-time data, and dispatching charging robots or logistics vehicles to deploy mobile charging piles in advance; in response to a charging peak in the business area, giving priority to logistics vehicles in standby state to provide mobile charging services; during low-peak charging periods, actively dispatching mobile charging piles for energy replenishment. By predicting future fluctuations in charging demand, the platform dispatches charging resources in advance and optimizes resource deployment. This can not only effectively cope with peak charging periods, but also replenish energy in advance during low-peak periods to avoid idle equipment; during peak charging demand periods, the platform can give priority to dispatching logistics vehicles to provide supplementary services, thereby ensuring full utilization of charging equipment during high-demand periods.

[0026] In some specific embodiments, it is determined whether the current mobile charging pile can meet the expected charging demand: mc ≥C t ; If it is satisfied, the mobile charging pile will be dispatched first; if it is not satisfied, the charging time will be calculated:

[0027] And judge whether to continue charging according to the demand within the charging time: C remaining =Ct -E mc ×min(1,T mc ), dispatch logistics vehicles for subsequent charging, and calculate the arrival time of logistics vehicles In response to the arrival time of the logistics vehicle T log-arrive No more than the remaining charging time T of the current mobile charging pile mc , total charging time T total =T mc +T log ; In response to the arrival time of the logistics vehicle T log-arrive Exceed the remaining charging time T of the current mobile charging pile mc , total charging time T total =T log-arrive +T log , continuous charging time Among them, E mc Indicates the remaining power of the current mobile charging pile, C t Indicates the expected charging capacity, T mc Indicates the current charging time of the mobile charging pile, T other It represents the time it takes for logistics vehicles to dispatch mobile charging piles from other business areas to the vehicle location, T base represents the time for logistics vehicles to dispatch mobile charging piles from charging base stations, P mc Indicates the charging power of the mobile charging pile, d log represents the distance between the logistics vehicle and the vehicle to be charged, v log Represents the average transportation speed of logistics vehicles, P log Indicates the charging power of the charging pile carried by the logistics vehicle. The platform can dynamically optimize the scheduling according to different charging resources and transportation time costs to ensure that the charging task is completed in the shortest time, thus improving the user experience.

[0028] According to a second aspect of the present invention, a charging system for electric vehicles is proposed, comprising a platform for executing the above-mentioned charging method, a mobile charging pile, a charging robot, a logistics vehicle and a charging base station. Through the above-mentioned efficient charging resource scheduling system, efficient allocation and execution of charging tasks can be achieved.

[0029] In some specific embodiments, the business area also includes fixed charging piles. When the fixed charging piles are idle, charging is performed through the fixed charging piles first. When the fixed charging piles are idle, charging is performed through the fixed charging piles first. This can improve the efficiency of the use of fixed charging piles and reduce the burden on mobile charging piles and charging robots; this strategy can reasonably allocate fixed and mobile charging resources while ensuring efficient scheduling to avoid waste of resources.

[0030] In some specific embodiments, the charging base station is deployed in the form of a container in an area where charging can be performed. The charging base station is deployed in the form of a container, which can conveniently perform charging in areas with high charging demand, especially in areas with high temporary charging demand. The container deployment form also helps to achieve rapid installation and movement of the base station.

[0031] The electric vehicle charging method and system proposed by the present invention have the following technical effects:

[0032] Flexible charging scheduling and resource management: By combining multiple charging methods (fixed charging piles, mobile charging piles, charging robots, logistics vehicles, etc.) and intelligent platform scheduling, this solution can achieve flexible and efficient charging task allocation and execution based on different regions, different user needs and charging equipment status.

[0033] Intelligence and dynamic optimization: The system predicts fluctuations in charging demand based on real-time data, performs dynamic scheduling, and optimizes resource deployment, thereby avoiding idleness and overload of charging equipment.

[0034] Improve user experience and charging efficiency: Through intelligent scheduling and relay charging mechanism, the system can complete the charging task in the shortest time, significantly improving charging efficiency and user experience, especially during high-demand periods.

[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the relevant invention are shown in the accompanying drawings.

[0040] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0041] Figure 1 A flow chart of a charging method for an electric vehicle according to an embodiment of the invention is shown. Figure 1 As shown, the specific steps include the following:

[0042] S1: In response to receiving a charging demand from a client, analyzing and determining a service area of ​​a vehicle to be charged.

[0043] In a specific embodiment, the charging demand includes the vehicle model, vehicle location information, remaining power information and expected charging capacity. The platform dispatches the mobile charging pile according to the remaining power information, expected charging capacity and available power of the mobile charging pile. The expected charging capacity is calculated based on the charging target power submitted by the user and the current remaining power of the vehicle; if the user does not submit a specific charging target, the expected charging capacity is estimated based on the battery capacity of the vehicle model and historical charging records. By considering the vehicle model, vehicle location information, remaining power information and expected charging capacity, a customized charging plan can be provided for each user, and the platform can accurately dispatch mobile charging piles to meet the charging needs of different electric vehicles.

[0044] S2: Based on the configuration of mobile charging piles and charging robots in the business area, the platform allocates charging resources according to charging demand and charging priority, including:

[0045] S21: In response to the availability of mobile charging piles and charging robots in the business area, the platform sends a charging work order to the charger in the business area, controls the charging robot to carry the mobile charging pile to the location of the vehicle to be charged, and the charger plugs in the gun and starts charging;

[0046] S22: In response to the lack of available charging resources in the business area, the platform sends a charging work order to the power delivery personnel of the logistics vehicle, and pushes the mobile charging piles of the available charging base stations around the logistics vehicle according to the distance. The power delivery personnel go to the charging base station to load the mobile charging pile and deliver it to the location of the vehicle to be charged according to the prompt of the platform, and then plug in the gun to start charging;

[0047] S22 also includes that after the platform receives the charging work order, it analyzes the charging resources in other business areas around the business area of ​​the vehicle to be charged, and in response to the existence of available charging resources in other business areas and the dispatch distance of the logistics vehicle is less than the distance to the charging base station for dispatching mobile charging piles, the charging work order is sent to the logistics vehicle and other business areas, and the logistics vehicle is dispatched to other business areas to load the available mobile charging piles from the charging robot and deliver them to the location of the vehicle to be charged, and then plug in the gun to start charging.

[0048] In a specific embodiment, the charging resources deployed in the business area are specifically multiple mobile charging piles and charging robots. The charging robots can be detachably equipped with mobile charging piles. In response to receiving a charging work order for cross-regional scheduling issued by the platform, the logistics vehicle arrives at the scheduling area and cooperates with the charging robot to transfer the mobile charging piles carried by the charging robot to the logistics vehicle, and delivers them to the business area with charging needs for charging operations according to the information on the charging work order. From the deployment perspective: the separate design of the charging robot and the mobile charging pile allows the mobile charging pile to be deployed separately in various charging scenarios, and the charging robot only participates in the task when needed. For example, in high-demand areas, multiple mobile charging piles can be deployed separately and dispersedly to ensure the breadth of resource coverage. In low-demand areas, mobile charging piles in other areas can be dynamically dispatched to reduce the idleness and waste of charging resources; mobile charging piles do not need to be always attached to the charging robot. When dispatching across regions, a single charging pile can be quickly transported to the target area by a logistics vehicle, and the charging robot can stay in the current business area and continue to serve other vehicles to avoid long-term idleness; in parking lots, residential areas and other scenarios, mobile charging piles can be placed separately at fixed points for charging, while charging robots can handle more complex mobile tasks. The flexible deployment method can meet the personalized needs of multiple scenarios.

[0049] In a specific embodiment, the detachable design allows the mobile charging pile to serve multiple vehicles at the same time as an independent charging unit, and the charging robot only needs to operate during transportation or dynamic adjustment. This division of labor greatly improves the utilization rate of charging resources. The separate design of the mobile charging pile and the charging robot simplifies the equipment maintenance process. The mobile charging pile can be repaired, replaced or scheduled for energy replenishment separately without affecting the task execution of the charging robot. At the same time, the system is more scalable, and the new mobile charging pile can be seamlessly integrated into the existing charging network. In the event of emergency tasks or peak charging needs, mobile charging piles can be quickly transported from other business areas by logistics vehicles to dynamically replenish resources without the need to dispatch the entire equipment together. This flexibility allows the system to respond to sudden demands and maximize the use of existing equipment.

[0050] In a specific embodiment, it is determined whether the current mobile charging pile can meet the expected charging demand: mc ≥Ct ; If it is satisfied, the mobile charging pile will be dispatched first; if it is not satisfied, the charging time will be calculated: And judge whether to continue charging according to the demand within the charging time: C remaining =C t -E mc ×min(1,T mc ), dispatch logistics vehicles for subsequent charging, and calculate the arrival time of logistics vehicles In response to the arrival time of the logistics vehicle T log-arrive No more than the remaining charging time T of the current mobile charging pile mc , total charging time T total =T mc +T log ; In response to the arrival time of the logistics vehicle T log-arrive Exceed the remaining charging time T of the current mobile charging pile mc , total charging time T total =T log-arrive +T log , continuous charging time Among them, E mc Indicates the remaining power of the current mobile charging pile, C t Indicates the expected charging capacity, T mc Indicates the current charging time of the mobile charging pile, T other It represents the time it takes for logistics vehicles to dispatch mobile charging piles from other business areas to the vehicle location, T base represents the time for logistics vehicles to dispatch mobile charging piles from charging base stations, P mc Indicates the charging power of the mobile charging pile, d log represents the distance between the logistics vehicle and the vehicle to be charged, v log Represents the average transportation speed of logistics vehicles, P log Indicates the charging power of the charging pile carried by the logistics vehicle.

[0051] In a specific example, it is assumed that the remaining power of the vehicle to be charged is R t =10KWh, expected charging capacity C t =40KWh. The current remaining power of the mobile charging pile is E mc =20KWh, charging power P mc = 10KW. The remaining power of the charging pile carried by the logistics vehicle is E log =50KWh, charging power p log =10KWh. Mobile charging station distance d mc =5km, logistics vehicle distance d log =10km. Average speed of logistics vehicle v log=40km / h. Calculation process: The current charging time of the charging pile is: The current charging pile can charge 20kWh for electric vehicles, and the remaining demand is: C remaining =40-20=20KWh; logistics vehicle arrival time: Logistics vehicle continued charging time: The logistics vehicle will continue to charge the remaining 20kWh of electricity: Total charging time: due to the arrival time of the logistics vehicle T log-arrive = 15min is less than the remaining charging time T of the current charging pile mc = 2h, so the arrival time of the logistics vehicle can be calculated in parallel: T total =T mc +T log =2+2=4h; Conclusion: In this case, the arrival time of the logistics vehicle does not exceed the remaining charging time of the charging pile, so the arrival time of the logistics vehicle does not need to be calculated additionally, and the entire charging process is parallel, with a total time of 4 hours.

[0052] In a specific embodiment, the platform dynamically adjusts the allocation of charging resources based on the following rules: the distance between the vehicle to be charged and the mobile charging pile, whether the current power of the mobile charging pile meets the expected charging amount of the vehicle to be charged, the use status of the mobile charging pile and the idle time after completing the current task, the charging urgency of the vehicle to be charged, and the waiting time of other scheduled charging tasks. The platform dynamically optimizes the deployment of charging resources based on real-time data, specifically including: predicting future charging demand fluctuations in the business area based on real-time data, and dispatching charging robots or logistics vehicles to deploy mobile charging piles in advance; in response to the peak of charging in the business area, giving priority to calling logistics vehicles in standby state to provide mobile charging services; in the low-peak period of charging, actively dispatching mobile charging piles for energy replenishment. The platform can intelligently schedule and adjust priorities: based on multiple factors (such as the distance between the charging pile and the vehicle, the power of the charging pile, the urgency of charging, etc.), the platform can dynamically adjust the allocation of charging resources to give priority to the completion of high-priority charging needs; through the intelligent adjustment of multiple factors, the platform can optimize the scheduling of charging resources in real time, avoid resource waste and meet the needs of vehicles in urgent need of charging, so as to improve the flexibility and response speed of the system. It can also predict charging demand and deploy resources in advance. By predicting the fluctuation of future charging demand, the platform can dispatch charging resources in advance and optimize resource deployment. This can not only effectively cope with the peak charging period, but also replenish energy in advance during the off-peak period to avoid idle equipment. During the peak charging demand period, the platform can give priority to dispatching logistics vehicles to provide supplementary services, thereby ensuring the full utilization of charging equipment during the high demand period.

[0053] Figure 2 A flow chart of a method for charging an electric vehicle according to a specific embodiment of the invention is shown. Figure 2As shown in the figure, the specific logic of the process is as follows:

[0054] User demand initiation: The user scans the QR code or submits the charging demand through the APP, and the system confirms the demand.

[0055] Demand analysis and task allocation: The system determines whether there are fixed charging piles in the user's area. If there are fixed charging piles, the user can directly scan the code or use the mobile phone to start charging; if there are no fixed charging piles, the system further analyzes the resource availability in the area. After the user scans the code, the system verifies whether the charging pile is idle. If it is idle, the user can quickly complete self-service charging.

[0056] The allocation logic specifically includes: if there is a charging robot in the area, the robot will be dispatched to move to the vicinity of the user's vehicle to complete charging; if there is no charging robot in the area, the system will dispatch a logistics vehicle to transport the charging pile or mobile battery equipment to the vehicle location. The system first determines whether the charging robot covers the user's required location. If there is an available robot, it will automatically dispatch it to the specified location; if the robot cannot cover it, the logistics vehicle will transport the charged equipment to the target location. The logistics vehicle can also replenish the reserves of mobile charging piles in the area to ensure service continuity.

[0057] After charging is completed, the system updates the task status and optimizes resource allocation efficiency.

[0058] The charging method of the electric vehicle has the following advantages:

[0059] Flexible response to multiple scenarios: Combining fixed and mobile charging modes to meet the diverse needs of users in cities, suburbs and special scenarios.

[0060] Intelligent resource scheduling: The cloud platform analyzes and allocates resources (fixed piles, robots, logistics vehicles) in real time to optimize operational efficiency.

[0061] Improved user experience: No need to worry about insufficient charging stations or difficulty charging in remote areas. Users only need to scan the code to submit their needs.

[0062] Wide service coverage: Not restricted by fixed infrastructure, the geographical boundaries of charging services are expanded through logistics vehicles and mobile equipment.

[0063] Figure 3 FIG. 1 shows a schematic diagram of a layout of a charging system for an electric vehicle according to an embodiment of the invention. Figure 3 As shown in the figure, a charging service system with a cloud platform as the core has been built, integrating the functional modules of fixed charging, mobile charging and user interaction to realize flexible and efficient electric vehicle charging services. Specifically, it includes:

[0064] 1. User-side module. The function is that users initiate charging demands through mobile devices (APP). The implementation method is: users select charging mode (fixed charging / mobile charging) in the APP; submit specific location, time and other information of charging demand. Reflection of data flow: demand data is uploaded to the cloud platform to form a work order.

[0065] 2. Cloud platform module. Its function is to serve as the control center of the system, handle user needs and coordinate resource allocation. The main tasks include: receiving charging needs submitted by users; analyzing the current charging resource situation, including: the availability of fixed charging piles and the distribution status of mobile charging equipment; generating and issuing task work orders, including: for fixed pile charging, notifying users to go to the designated charging pile location, and for mobile charging, dispatching logistics vehicles or charging robots to complete the service. Data interaction forms include: two-way communication with the user end to confirm the task status; interacting with hardware equipment such as logistics vehicles and fixed charging piles to complete resource allocation.

[0066] 3. Fixed charging module. Its function is to provide users with self-service charging services at fixed locations (communities, parking lots, etc.). The equipment consists of: fixed charging piles (with code scanning charging function) and charging guns (used to connect to the vehicle charging interface). The operation process includes: the cloud platform notifies the user to go to the nearest fixed charging pile; the user scans the code to start the charging device. The data interaction forms include: the fixed charging pile uploads the device status (idle / occupied) in real time; after charging is completed, the charging record is fed back to the cloud platform.

[0067] 4. Mobile charging module. Its function is to provide flexible door-to-door charging services when users cannot access fixed charging piles. The equipment consists of: mobile charging piles (carried by logistics vehicles or mobile robots, which can directly charge vehicles) and logistics vehicles (carrying mobile charging piles and going to the user's specified location). The operation process is as follows: After the cloud platform receives the mobile charging demand, it generates a task work order; dispatches the logistics vehicle to carry the mobile charging pile to the user's location; after the logistics vehicle arrives, it connects with the user's vehicle through the charging equipment to complete the charging task. The data interaction forms include: the mobile device feedbacks the location and task completion status to the cloud platform in real time.

[0068] 5. Logistics collaboration module. Its function is to ensure the mobility of charging equipment and provide supplies and support for charging services. The equipment includes: logistics vehicles (for mobile battery pack transportation). The operation logic is: when the charging demand in the area increases, the cloud platform dispatches logistics vehicles to transport mobile charging piles to the target area; regularly replenish the power of the service vehicle to improve the equipment turnover efficiency.

[0069] In a specific embodiment, the charging base station is deployed in the form of a container in an area where recharging is possible, and the charging robot and logistics vehicle can transport the mobile charging pile to the charging base station for recharging. The charging base station is deployed in the form of a container, which can conveniently recharge in areas with high charging demand, especially in areas with large temporary charging demand. The container deployment form also helps to achieve rapid installation and movement of the base station.

[0070] In a specific embodiment, an energy storage device (such as a lithium battery pack, supercapacitor or other form of energy storage device) may also be configured inside the charging base station, which is mainly used for the following two functions: Off-peak charging: During the time period when the grid load is low and the electricity price is cheap (such as at night), the energy storage device obtains electricity from the grid and stores it. This process can simultaneously charge the mobile charging piles inside the charging base station, making full use of the cost advantage of off-peak electricity prices. Peak discharge: During the period when the grid load is high and the electricity price is expensive (such as the peak period during the day), the energy storage device supplies power to the mobile charging piles. By reasonably allocating electricity during the period when the electricity price fluctuates, the energy storage device can effectively reduce the operating cost of the charging base station while improving the stability of the grid load.

[0071] In a specific embodiment, the charging robot and mobile charging pile can be regarded as a "small mobile base station". Its deployment solution solves the problem that the existing fixed base stations cannot cover urban areas, mobile charging vehicles or mobile charging equipment are all integrated designs, the cost is extremely high, and it is difficult to disassemble the energy storage battery to achieve cross-regional deployment and scheduling. It has significant technical advantages and economic benefits. This approach combines the flexibility of equipment and the efficiency of service coverage, which is specifically reflected in the following aspects:

[0072] 1. Deployment flexibility and scenario adaptability: Charging robots and mobile charging piles are deployed as "small base stations", which can be flexibly dispersed in different areas according to charging needs, without the need to concentrate on large fixed base stations. It is particularly suitable for scenarios such as urban parking lots, residential communities, and commercial plazas where charging needs are dense but unevenly distributed. In temporary peak scenarios, small base stations can be deployed quickly and transferred to other areas after the event ends, avoiding the waste of fixed base station resources.

[0073] 2. Improve service efficiency and responsiveness: Small base stations can quickly respond to user charging needs within the service area, and transport mobile charging piles to the vicinity of vehicles through charging robots, shortening user waiting time. When charging demand in a certain business area decreases and charging demand in other business areas increases, logistics vehicles can be used to grab the mobile charging piles on the charging robot and transport them to other areas in need, dynamically adjusting the service scope and improving resource utilization.

[0074] 3. Reduced construction costs: Compared with traditional large fixed base stations, small base stations do not require a lot of civil engineering and supporting facilities. They only need to deploy charging robots and mobile charging piles in key areas.

[0075] 4. Improve energy utilization efficiency: Small base stations in different business areas can share energy by transporting mobile charging piles through logistics vehicles to balance the power load in different areas.

[0076] 5. Better scalability: The components of the small base station (charging robot and mobile charging pile) are designed in a modular and separate manner, which is convenient for adding equipment or upgrading existing hardware at a later stage to meet the future growth in charging demand.
