Description

Technical Field

[0001] The present application relates to the field of new energy vehicle charging, and more specifically to a method for operating a new energy vehicle charging cart. The present application also relates to a method for allocating a new energy vehicle charging cart and a method for a new energy vehicle to request a charging cart. Background Art

[0002] At present, in the process of popularization and use of new energy vehicles, the convenience and mobility of charging facilities have become an important consideration. Traditional new energy vehicle charging piles are usually fixed in a specific location and cannot be flexibly moved and adapted to the needs of different scenarios. The limitation of such fixed charging piles brings certain inconveniences and limitations to the charging of new energy vehicles.

[0003] In order to solve this problem, a new type of mobile charging car technology is proposed, which can provide flexible and convenient charging services for new energy vehicles, changing the "car looking for charging pile" to "charging pile looking for car", which can greatly improve the charging efficiency, saving both space and time.

[0004] However, the mobile charging carts in the prior art still have major defects in practical applications. For example, the scheduling mechanism is imperfect and consumes extra labor costs. Due to the imperfect scheduling mechanism, users often need to find and determine the appropriate charging cart by themselves during use. After use, users need to find an available charging pile to return it. The above factors make the user experience of using the existing mobile charging carts not good.

[0005] Therefore, it is necessary to provide a new technical solution for the operation method of the charging cart for new energy vehicles, optimize the scheduling mechanism of the existing charging cart, so as to improve the operation efficiency of the charging cart and optimize the user experience.

[0070] The first embodiment of the present application provides an operating method for a new energy vehicle charging cart.

[0071] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of the charging cart provided in the first embodiment of the present application. The charging cart 100 includes a main controller 101 and a self-moving controller 102. In one embodiment, the charging cart also includes an electronic lock 103.

[0078] Data recording and analysis: The main controller can record various parameters and events during the charging process, conduct data analysis and statistics, and provide data support for the optimization and improvement of charging services.

[0079] The main controller provides the charging cart with high-performance processing capabilities and a stable and reliable working environment to ensure efficient operation of the charging service and user experience.

[0080] The self-propelled controller is responsible for controlling the movement and navigation of the charging cart. The main functions of the self-propelled controller include:

[0081] Navigation system: The autonomous controller is equipped with positioning sensors (such as GPS, inertial navigation system, etc.) and environmental perception sensors (such as lidar, camera, etc.), which can realize accurate navigation and path planning by perceiving the environment and location information around the vehicle in real time.

[0088] Therefore, the setting of the self-moving controller can significantly improve the operating efficiency and service quality of the charging vehicle.

[0089] The electronic lock 103 is used to lock the charging cart and the connected equipment to each other to ensure the safety of the operation process.

[0090] In the prior art, a charging pile is used to charge a target vehicle to be charged. A charging gun will be provided on the charging pile. By inserting the charging gun into the charging port of the target vehicle, the charging task can be performed. In the present application, the charging pile is used to replenish energy for the charging cart. The charging cart first replenishes the electric energy from the charging pile and stores the electric energy in the battery pack. The charging cart goes to the location of the target vehicle, and after the target vehicle is connected to the charging cart, a discharge circuit is established. The charging cart transfers the electric energy stored in the battery pack to the target vehicle, thereby completing the task of the charging cart to charge the target vehicle. Therefore, the charging cart in this embodiment is an energy storage device that is easy to move.

[0091] Please combine Figure 2 Understand the method in the first embodiment of the present application. Figure 2 This is a flow chart of the operating method of the new energy vehicle charging cart provided in the first embodiment of the present application.

[0092] In the first embodiment of the present application, the charging request information of the vehicle to be charged can be sent directly to the new energy charging vehicle through short-range wireless communication (for example, Bluetooth, RFID (radio frequency identification), satellite communication, etc.) to realize distributed scheduling of the charging vehicle.

[0093] A method for operating a new energy vehicle charging vehicle provided in a first embodiment of the present application is used for a new energy vehicle charging vehicle. The method for operating the new energy vehicle charging vehicle includes steps S201 to S207:

[0094] Step S201, the main controller is used to obtain the current state information and current charging demand information of the current charging car, and determine whether the current charging car can be used as the target charging car; if so, it sends a confirmation message that the charging task can be executed;

[0095] Step S202: If the current charging vehicle is determined to be the target charging vehicle, the main controller is used to obtain the position information of the target vehicle to be charged as the first position information, and plan a first driving path according to the first position information and the current position information of the current charging vehicle;

[0096] Step S203, the self-moving controller controls the current charging vehicle to move to the first position where the target vehicle is located according to the first driving path, and performs the charging task;

[0097] Step S204, after the charging task is completed, the main controller queries the occupancy status of the charging pile, and determines the target charging pile and its location information according to the occupancy status;

[0098] Step S205, the main controller uses the location information of the target charging pile as the second location information, and plans a second driving path from the first location to the second location;

[0099] Step S206, the self-moving controller controls the current charging vehicle to move to the location of the target charging pile according to the second driving path;

[0100] Step S207, the main controller controls the current charging vehicle moved to the location of the target charging pile to perform vehicle-pile confirmation and automatic energy replenishment connection functions, establishes an automatic energy replenishment connection circuit with the target charging pile, and realizes energy replenishment for the current charging vehicle.

[0101] In the specific implementation, the user of the new energy vehicle can send the charging request information that needs to be charged through the APP application on the handheld mobile smart terminal, or the APP application set by the new energy vehicle itself, or the one-key charging button light method specially set by the new energy vehicle itself. The charging request information contains the charging-related information of the new energy vehicle to be charged (i.e., the target vehicle), i.e., the charging request information, for example, including: its own charging needs (how much electricity needs to be charged), and the location, vehicle identity information, etc. The charging request information can be sent directly to the new energy charging car through short-distance wireless communication (short-distance dispatching method), or it can be sent to the charging management platform through long-distance wireless communication. Then, the charging management platform calls the new energy charging car with suitable conditions according to the geographical location information and status information (long-distance dispatching method).

[0102] Since the detection range of the above-mentioned short-distance communication method is limited, it may not be possible to find a suitable charging vehicle, but the short-distance communication method is more convenient for dispatching charging vehicles. Therefore, the short-distance dispatching method can be prioritized and combined with the long-distance dispatching method to achieve a combination of the advantages of the long-distance dispatching method and the short-distance dispatching method.

[0103] Usually, short-range communication can be used to find out whether there is a charging cart within a predetermined range, and priority is given to finding the charging cart within the short-range communication range; if not found, the charging cart automatically switches to long-range communication, searches through the remote server for charging carts in a larger range, and remotely determines the charging cart that is relatively close.

[0104] In the long-distance dispatching method, the charging management platform can determine the most suitable charging vehicle to come for charging; in the short-distance dispatching method, since it does not go through the charging management platform, how to choose a charging vehicle that is as close as possible requires a corresponding selection plan.

[0105] In order to select a charging cart that is as close as possible in the short-distance scheduling method, in the first embodiment of the present application, ultra-wideband technology is used to achieve short-distance communication and determine the distance between the charging cart and the new energy vehicle.

[0106] Ultra-Wideband (UWB) is a wireless communication technology known for its high-speed data transmission and high-precision positioning. It uses a time difference positioning algorithm to achieve accurate positioning of short-range wireless communications and determine the specific distance range during the accurate positioning process. It operates in the frequency band of 3.1 to 10.6 GHz, can transmit large amounts of data with low power consumption, and provide centimeter-level positioning accuracy. UWB is commonly used in indoor positioning systems, high-speed data transmission, and location tracking in smart spaces. The technology also has strong anti-interference capabilities and can provide stable positioning services in complex indoor environments.

[0107] During the implementation process, first select a suitable UWB module or development board, such as Decawave's DWM1000 or DWM3000, install UWB tags or modules on the charging cart and new energy vehicles, and configure them so that the charging cart can communicate with the new energy vehicle. The charging cart can use a positioning algorithm based on time difference of arrival (TDOA) to calculate the position of the new energy vehicle. In actual applications, new energy vehicles equipped with UWB tags or modules will first search for charging carts within a predetermined range, and select charging carts that are closer and meet the requirements. If there are any, communication will be established with the charging cart. The charging cart can obtain the location of the new energy vehicle as the first location information and other charging demand information. The charging cart can plan the first driving path based on the current location combined with the first location information, so as to realize the automatic search for charging carts by new energy vehicles and the automatic scheduling of charging carts.

[0108] Please see Figure 3 , Figure 3 The present application is a flowchart of a method for determining whether the current charging vehicle can be used as a target charging vehicle, provided in a first embodiment.

[0109] In a preferred embodiment, the obtaining of the current state information and the current charging demand information of the current charging vehicle and determining whether the current charging vehicle can be used as the target charging vehicle comprises the following steps:

[0110] Step S301, the main controller obtains the current charging demand information of the target vehicle that issues the charging request, including the charging capacity demand data of the target vehicle; and obtains the current state information of the current charging vehicle, including the storage capacity data of the current charging vehicle;

[0111] Step S302, determining whether the stored power data of the current charging vehicle is greater than the charging power demand data of the target vehicle;

[0112] Step S303-1: If yes, determine that the current charging car can be used as the target charging car;

[0113] Step S303-2: If not, feedback information indicating that the current charging vehicle cannot be used as the target charging vehicle is returned.

[0114] Among them, the current charging demand information can be obtained in two ways. Method 1, the background obtains it from the user end and forwards it to the main controller of the charging car. Method 2, the target vehicle directly establishes a local connection with the charging car, and the target vehicle directly sends the charging demand information to the charging car. The advantage of method 2 is that it is still not affected in places with poor network connection signals, and can provide charging scheduling services to users normally.

[0115] In the case of passing, the storage power data of the charging car and the charging demand data of the target vehicle are expressed in capacity units such as kilowatt-hours, and can be converted in equal amounts, that is, if the storage power of the charging car is 20 kWh, theoretically, the power that can be charged for the target vehicle is 20 kWh. However, considering that electric energy may be lost during transmission, or the battery pack storing electric energy may also need to provide electric energy for the operation of the charging car itself. Therefore, in the process of judging whether the storage power data of the current charging car is greater than the charging demand data of the target vehicle, the size matching relationship between the storage power data of the current charging car and the charging demand data of the target vehicle should be considered according to the actual situation. However, in any case, it should be ensured that the storage power data of the current charging car must be greater than the charging demand data of the target vehicle. On this basis, it is possible to meet the charging demand of the target vehicle.

[0116] If it is determined according to the preset rules that the current charging cart cannot meet the charging needs of the target vehicle to be charged, feedback information that the current charging cart cannot be used as the target charging cart will be sent to the main controller, and the main controller will further deploy a charging cart that meets the requirements based on the feedback information.

[0117] After determining the target charging vehicle, the charging vehicle needs to go to the location of the target vehicle to be charged and prepare to perform the charging task.

[0118] The charging cart waiting for scheduling may be replenishing energy on the charging pile, or it may be used by the user. If it is in the state of replenishing energy, it means that the charging cart is connected to the charging pile and locked by an electronic lock. If you need to use the charging cart that is being replenished, you need to unlock the charging cart from the charging pile. In addition, even if the charging cart is in the state of being used by the user, the charging cart in use can also receive relevant information about the scheduling. Furthermore, the main controller of the charging cart in use can participate in the scheduling process through the received scheduling information. Therefore, before the target charging cart goes to the location of the target vehicle, it is necessary to determine whether the target charging cart is in a state of being locked with the charging pile.

[0119] Please see Figure 4 , Figure 4 A flowchart of the steps performed when the current charging cart and the charging pile are connected is provided for the first embodiment of the present application. In a preferred embodiment, before the step where the self-mobile controller controls the current charging cart to move to the first position where the target vehicle to be charged is located, if the current charging cart is connected to the charging pile, the following steps are performed:

[0120] Step S401, the main controller controls the electronic lock of the current charging vehicle and the charging pile to unlock;

[0121] Step S402, sending a signal that the target charging vehicle has been unlocked to the self-mobile controller;

[0122] Step S403: the self-moving controller determines that the target charging cart can move according to the signal indicating that the target charging cart has been unlocked.

[0123] After the current charging vehicle moves to the first position where the target vehicle is located and before executing the charging task, the method further includes:

[0124] Perform vehicle-to-vehicle identity verification based on the identity information of the current charging vehicle and the identity information of the target vehicle;

[0125] After the identity is verified, the main controller controls the current charging vehicle to automatically charge and connect with the target vehicle.

[0126] Since the charging interfaces corresponding to different vehicles may not be the same, before executing the charging task, the identity information of the current charging vehicle should be checked with the identity information of the target vehicle. If the check is correct, it means that the identity information of the current charging vehicle matches that of the target vehicle, and the interface also matches, and the charging task can be executed.

[0127] After the charging task is completed, the target charging car needs to be connected to the charging pile for energy replenishment to ensure that it can provide power for other vehicles to be charged.

[0128] In a preferred embodiment, the charging vehicle can automatically find an available charging station for charging. Figure 5 , Figure 5 A flow chart of a method for determining a target charging pile and its location information provided in the first embodiment of the present application. The main controller queries the occupancy status of the charging pile, and determines the target charging pile and its location information according to the occupancy status, including:

[0129] Step S501, obtaining occupancy status information and / or queue information of each charging pile within a first preset range;

[0130] Step S502, determining a target charging pile according to the occupancy status information and / or the queuing information and according to preset conditions;

[0131] Step S503, sending predetermined information for the target charging pile, and acquiring the location information of the target charging pile as the second location information;

[0132] Step S504, the predetermined information at least includes the estimated time for the current charging vehicle to arrive at the target charging pile and the estimated usage time.

[0133] The occupancy status information of the charging pile includes the occupancy status. When the charging car queries the occupancy status of the charging pile, the occupancy status that can be obtained includes being in use and available for use. If the occupancy status is available for use, the charging pile is determined as the target charging pile. If the occupancy status is in use, it means that the current charging pile is not available at this time. At this time, it can be detected whether other charging piles are available for the charging car. If none of them are available, the expected idle time of the charging pile can be estimated by obtaining the energy replenishment status of the charging car currently connected to the charging pile. The queuing information includes the estimated time information required for the charging car that is being replenished on the charging pile to complete the replenishment, the number of charging cars that have been queuing for energy replenishment on the charging pile, and the time information required for these charging cars to complete the replenishment. According to the obtained charging status information of the charging vehicles associated with the charging piles, the availability of the charging piles is sorted. For example, the charging piles with fewer charging vehicles associated with the charging piles should be ranked before the charging piles with more charging vehicles associated with the charging piles; the charging piles with shorter total time required for the charging vehicles associated with the charging piles to complete the charging should be ranked before the charging piles with longer total time required for the charging vehicles associated with the charging piles to complete the charging. The specific rule settings can be adjusted in actual applications and are not limited to the above sorting rules.

[0134] Since it takes a certain amount of time for the charging car to reach the charging pile, after determining the target charging pile, it is also necessary to obtain reservation information, which includes the estimated time for the charging car to reach the target charging pile and the estimated time for using the target charging pile for energy replenishment. In order to maximize the utilization rate of the charging pile, this application adopts a technical solution for the charging car to automatically search for and dispatch charging piles, which greatly increases the utilization rate of the charging piles, obtains the occupancy status information and queuing information of the charging piles in advance, and improves the efficiency of the charging car in determining the target charging pile. Furthermore, the charging efficiency of the charging car is improved.

[0135] In a preferred embodiment, when the charging car reaches the location of the target charging pile, the main controller can control the establishment of an energy replenishment circuit between the charging car and the target charging pile. This step does not require human intervention, and the charging car can complete the connection by itself. Specifically, the main controller controls the current charging car that has moved to the location of the target charging pile to perform the car-pile confirmation and automatic energy replenishment connection functions, establish an automatic energy replenishment connection circuit with the target charging pile, and realize energy replenishment for the current charging car, including:

[0136] Perform vehicle-pile identity verification based on the identity information of the current charging vehicle and the identity information of the target charging pile;

[0137] After the identity is verified, the charging interface on the target charging pile is identified and the location of the charging interface is obtained;

[0138] According to the position of the charging interface, adjust the position of the charging cart;

[0139] Determining that the current position of the charging vehicle is within the range of the preparatory docking position;

[0140] Connect the power supply interface of the current charging car to the charging interface of the target charging pile to establish an energy replenishment circuit;

[0141] By means of the circuit signal, it is confirmed that the energy replenishment circuit has been established, and then the electronic lock between the power intake interface of the current charging vehicle and the charging interface of the target charging pile is controlled to be locked.

[0142] The main controller assigns a target charging pile to the charging cart. After the charging cart arrives at the location of the target charging pile, the main controller immediately obtains the information of the charging pile to verify whether the identity information of the charging cart and the identity information of the target charging pile are consistent with the assigned information. After confirming that the verification is correct, the charging interface on the target charging pile is identified, the detailed location of the charging interface is obtained, and the parking position of the charging cart is adjusted according to the position. After determining that the parking position is within the range of the preparatory docking position, the power interface of the charging cart can be controlled to connect with the charging interface of the target charging pile to establish an energy replenishment circuit. After confirming that the circuit is successfully established, the power interface of the charging cart and the charging interface of the target charging pile are directly electronically locked to avoid safety hazards caused by disconnection of the charging circuit during charging.

[0143] The operation method of the above-mentioned new energy vehicle charging cart provided by the present application adopts a self-moving charging cart, which solves the inconvenience and limitations of fixed charging piles in the prior art; the technical solution provided by the present application uses a main controller for communication and control, and cooperates with a self-moving controller and an electronic lock to enable the charging cart to process information and dispatch by itself, achieving the technical effect of autonomous charging and autonomous energy replenishment of the charging cart, and improving the problem of low charging efficiency and poor user experience of the new energy vehicle charging cart. The above solution optimizes the use process of the charging cart and significantly improves the flexibility of charging new energy vehicles.

[0144] Second embodiment

[0145] The second embodiment of the present application provides a method for deploying a new energy vehicle charging cart, which is related to the method for operating the new energy vehicle charging cart provided in the previous embodiment. For specific related matters, please refer to the description of the previous embodiment.

[0146] Please see Figure 6 , Figure 6 A flow chart of a method for allocating charging carts for new energy vehicles provided in the second embodiment of the present application for a charging management platform. A method for allocating charging carts for new energy vehicles provided in the second embodiment of the present application is used in a charging management platform and includes the following steps:

[0147] Step S601, obtaining the latest status information of each charging vehicle within a predetermined range;

[0148] Step S602, according to the latest status information, select the working status of each charging vehicle as a waiting state or a charging and recharging state, and send current charging demand information;

[0149] Step S603, receiving feedback information from each charging vehicle;

[0150] Step S604, among the charging vehicles that provide feedback information indicating that they can perform the charging task, select a target charging vehicle according to preset conditions;

[0151] Step S605: Send the location information of the target vehicle to the target charging vehicle.

[0152] The technical solution of the second embodiment of the present application is applied to the charging management platform, which acts as a dispatching center to uniformly handle the related tasks of charging vehicles. Specifically, the user sends charging request information to the charging management platform through long-distance wireless communication (for example, an APP application on a handheld mobile smart terminal, or an APP application set by the new energy vehicle itself, or a one-key charging button light method specially set by the new energy vehicle itself, etc.), and then through the charging management platform, according to the geographical location information and status information, etc., the new energy charging vehicle with suitable conditions is called.

[0153] For example, when a user runs out of power while traveling and cannot move, the user can remotely send the charging demand information of the vehicle to be charged. After receiving the charging demand information sent by the user, the charging management platform can dispatch the corresponding charging car for the user. In this process, the user does not need to go to the location of the charging car in person. The charging management platform only needs to perform unified remote dispatch to assign the qualified charging car to the location required by the user.

[0154] The acquisition of the latest status information is to obtain the current status of the charging vehicle in real time to determine how to allocate the charging demand of the target vehicle. The predetermined range can be a range specified by the user or a range determined according to the location of the target vehicle.

[0155] In a preferred embodiment, the deployment method of the new energy charging vehicle further includes:

[0156] When the location information of the target vehicle is sent to the target charging vehicle, the identification information of the target vehicle is also sent, and the identification information of the target charging vehicle is sent to the target vehicle. The identification information may include the number of the target charging vehicle, which is unique and can distinguish the identities of different charging vehicles.

[0157] Before obtaining the latest status information of each charging vehicle within the predetermined range, perform the following steps:

[0158] Receive charging request information sent by the target vehicle to be charged, and parse and generate current charging demand information as well as the location information and identification information of the target vehicle.

[0159] Although the allocation method of the second embodiment of the present application is implemented on the charging management platform, the judgment logic is consistent with the above embodiment. In general, the allocation method of the new energy charging car of the second embodiment of the present application has a perfect charging car allocation mechanism, which makes up for the deficiencies in the operation logic of the charging car in the prior art and improves the operation efficiency of the charging car.

[0160] Third embodiment

[0161] The third embodiment of the present application provides a method for a new energy vehicle to request a charging vehicle, which is related to the above-mentioned embodiment, and the relevant parts can refer to the description of the above-mentioned embodiment.

[0162] Please see Figure 7 , Figure 7 A flowchart of a method for a new energy vehicle to request a charging car provided in the third embodiment of the present application. The method for a new energy vehicle to request a charging car provided in the third embodiment of the present application is used for a new energy vehicle, and includes:

[0163] Step S701, generating charging request information according to its own charging needs, location, and vehicle identity information;

[0164] Step S702, sending the charging request information to a charging management platform;

[0165] Step S703, receiving identification information of the target charging vehicle sent by the charging management platform.

[0166] During the charging process of the new energy vehicle, it is necessary to cooperate with the charging cart. Therefore, the method for the new energy vehicle to request the charging cart provided in the third embodiment of the present application is used for the new energy vehicle.

[0167] New energy vehicles need to send their own charging needs to the charging management platform, which will coordinate the allocation of charging vehicles, etc. At the same time, new energy vehicles also receive the identification information of the target charging vehicle sent by the charging management platform to complete the connection between the new energy vehicle and the target charging vehicle.

[0168] The communication between new energy vehicles and the charging management platform reduces the manpower input in the dispatching process of charging vehicles, which can improve charging efficiency, optimize energy utilization and improve user experience.

[0169] Fourth embodiment

[0170] The fourth embodiment of the present application provides another method for a new energy vehicle to request a charging vehicle, which is related to the above-mentioned embodiment, and the relevant parts can refer to the description of the above-mentioned embodiment.

The method for a new energy vehicle to request a charging car provided in the fourth embodiment of the present application is used for a new energy vehicle, and includes:

[0172] Step S801, generating charging request information according to its own charging needs, location, and vehicle identity information;

[0173] Step S802, sending the charging request information in a broadcast manner;

[0174] Step S803, receiving a response from the target charging vehicle, which includes identification information of the target charging vehicle.

[0175] In the fourth embodiment of the present application, the actual application scenario may include that when the user is within a certain range from the charging cart, a direct connection is established between the charging cart and the new energy vehicle through wireless communication, the charging cart can obtain the charging demand information of the new energy vehicle, and the charging carts can directly transmit information to each other.

[0176] The fourth embodiment of the present application uses broadcasting to send charging request information, directly conveying the charging demand to nearby charging carts without going through a charging management platform, thereby achieving complete self-organization of charging services, improving the response speed and coverage of charging carts, and making the deployment of charging carts more efficient.

[0177] The technical solutions of the above four embodiments, through the communication and coordination between the new energy vehicle and the charging car and the charging pile, not only reduce the labor cost, but also make the operation of the charging car more intelligent, improve the efficiency of charging the new energy vehicle, and significantly improve the user experience. At the same time, this solution also has high flexibility and convenience. Through the use of the self-movable new energy charging car, the "car looking for pile" actually becomes "pile looking for car", which saves both space and time. In addition, since the schemes of the four embodiments of the present application are arranged for the energy replenishment strategy of the new energy vehicle charging car on the charging pile, it is possible to adjust the energy replenishment time of the charging car to the low electricity consumption period, that is, to achieve full utilization of electric energy. At the same time, the energy replenishment time of the charging car is adjusted to the low electricity price period, and the time for charging the vehicle is adjusted to the peak electricity price period, so that a perfect operation idea can be provided for the operation side.
