[0002] At present, new energy vehicles generally use fixed DC charging piles for charging. When encountering charging peak, a large number of new energy vehicles queue up to wait for charging, wasting a lot of time. To solve this problem, if the "car looking for pile" is changed to "pile looking for car", the charging efficiency can be greatly improved, saving both space and time.

[0046] Considering that for power supply networks that implement fluctuating electricity prices, if new energy vehicles can take advantage of valley electricity prices, they can save a lot of money.

[0050] Many specific details are described in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present application, so the present application is not limited by the specific implementation disclosed below.

[0051] In the description of the present application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present application, "plurality" means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0052] A typical usage scenario of the embodiment of the present application may be a charging station with several charging piles and several charging carts that can recharge themselves. The charging cart can not only automatically connect to the charging piles for recharging, but also plan its own route so that it can automatically move to the location of the new energy vehicle that needs to be charged; of course, the charging cart can also be a hand-push type, and the staff is responsible for moving and recharging. When there is an idle position on the charging pile, the charging cart can use the idle charging pile to recharge. In particular, the charging cart can choose to recharge during the period when the electricity price is at a lower valley price as needed. In this way, combined with the charging behavior of new energy vehicles during normal working hours, the charging cart can become an energy storage and transportation device that helps the power grid to shave peaks and fill valleys.

[0053] The charging cart recommendation method and the charging cart billing method of the present application are both implemented by the computer background management system of the charging station; the background management system receives and senses the status of each charging cart through various sensors installed on the charging piles and the charging carts; and obtains information about new energy vehicles entering the charging station through methods such as user scanning codes and automatic vehicle identification; in coordination with the background management system of the charging station, owners of new energy vehicles can run mini-programs or APPs that cooperate with the above-mentioned background management system through mobile phones or the vehicle-mounted systems of new energy vehicles, for example, the mini-programs can be opened by scanning the QR code posted by the charging station through the WeChat scanning function, and relevant information such as the charging type and charging requirements of the new energy vehicle can be provided through the mini-programs; or, the new energy vehicle can be directly associated with the background management system of the charging station through short-range wireless communication methods such as Bluetooth to obtain relevant information such as the charging type and charging requirements of the new energy vehicle.

[0054] In this application, in order to distinguish between the two situations where the charging vehicle itself is charged through the power grid and the charging vehicle charges new energy vehicles, the charging of the charging vehicle itself through the power grid is referred to as energy replenishment.

[0055] First embodiment

[0056] The first embodiment of the present application provides a recommended method for charging a small vehicle, please refer to Figure 1 , Figure 1 This is a flow chart of a method for recommending a charging cart provided in the first embodiment of the present application. The method for recommending a charging cart provided in this embodiment includes steps S101 to S106.

[0057] This recommended method can be implemented by the background management system of the charging station to which the charging cart belongs; the background management system can manage the charging carts of a certain charging station or a certain geographical area, obtain relevant information of the charging cart at any time, and issue instructions to the charging cart.

[0058] Step S101, determining the charging type and charging requirement of the target vehicle, wherein the charging requirement includes the required amount of supplementary power and the required charging completion time point.

[0059] This step is used to obtain charging-related information of the target vehicle. In the field of charging of new energy vehicles, obtaining charging-related information of the target vehicle (new energy vehicle to be charged) is a common technology. This step exists as a basic technology in this embodiment to provide the required information for subsequent steps.

[0060] A charging cart is a device for charging new energy vehicles. The charging cart generally needs to obtain electrical energy from the charging pile (power source) and store the electrical energy in its own energy storage battery. When the stored electrical energy is sufficient, the charging cart moves to the location of the vehicle to be charged and transmits the pre-stored electrical energy to the vehicle to be charged to charge the vehicle to be charged. Nowadays, charging carts are widely used in the field of charging new energy vehicles to meet the needs of high charging frequency and flexible charging locations for new energy vehicles.

[0061] The target vehicle refers to new energy vehicles, which are essentially electric vehicles. Therefore, the new energy vehicles, new energy vehicles, electric vehicles, electric vehicles, and vehicles to be charged that may appear in the following text all have the same meaning.

[0062] The charging type of the target vehicle includes the electrical interface type and the charging speed type.

[0063] The types of charging interfaces for new energy vehicles are not yet unified. Common ones include Combo model, CHAdeMO model, Tesla model, CCS model, and GB / T 20234 model, and there are compatibility issues between them. In the usage scenario of this application, the charging cart can have 1-2 charging interfaces, but it is difficult to prepare all the charging interfaces. For this reason, the same charging station can prepare several types of charging carts with different charging interface types. On the one hand, the charging cart can be recharged through the charging interface compatible with the charging pile, and on the other hand, it can use a method different from the charging interface of the charging pile to charge the new energy vehicle, which in fact expands the charging interface compatible with the charging pile.

[0064] The charging speed types of new energy vehicles include slow charging and fast charging; fast charging includes public charging including AC public charging and DC fast charging. Among them, slow charging (Level 1) is the most basic charging method, which is charged directly through a power supply device (110V or 220V) using a standard household power supply. This method is slow and suitable for daily low-mileage vehicle charging. The AC public charging (Level 2) uses dedicated AC charging equipment (usually 240V) to provide a faster charging speed than a home socket and is suitable for long-term parking in places such as shopping malls, hotels, and workplaces. The DC fast charging (DC Fast Charging) uses special DC charging facilities to charge faster and is suitable for fast charging needs during long-distance travel. These facilities can usually charge the battery to more than 80% in a short time.

[0065] In addition, there is currently wireless charging, which uses electromagnetic induction or other technologies to charge electric vehicles without physical contact. This technology is still under development.

[0066] The recommended method of charging cart provided in this embodiment is applicable to the above-mentioned various charging types; in this embodiment, combined with the needs of public scenes, fast charging is mostly used for explanation, and of course other existing charging methods not mentioned or not yet mature charging methods are not excluded; accordingly, the charging type is mainly the adaptation of the charging interface, and specifically, the adapted charging interface can be determined according to the actual conditions. In other words, according to the type of the charging interface of the target vehicle, the optional charging cart corresponding to the charging interface is determined.

[0067] The charging type can be determined by detecting the target vehicle. Different vehicle types have different charging interfaces, and different charging interfaces correspond to different charging interface protocols. The charging types that each charging interface can support are certain, but not necessarily unique. Information related to the charging type is contained in the target vehicle, and can be directly transmitted to the charging cart or the management background of the charging cart through the charging interface. The charging cart or its background management platform can directly obtain information related to the charging type to determine the charging type that matches the target vehicle. The charging type can also be directly transmitted to the charging cart system through user input, but for safety reasons, the charging type entered by the user is only used as an auxiliary reference, and the final judgment basis still needs to be determined based on the charging interface information.

[0068] The charging demand mainly includes the amount of electricity that the target vehicle needs to replenish and the expected time to complete the replenishment. Usually, in the process of charging the target vehicle, the user is most concerned about time-related data. For example, the time required for the target vehicle to replenish electricity, the expected completion time, the amount of electricity replenished during this time, and the fees required to be paid.

[0069] The required amount of supplementary electricity in the charging demand includes the amount of electricity that the user expects to supplement for the target vehicle this time. The amount of electricity is essentially counted in kilowatt-hours (kWh), but since the battery energy storage capacity of the target vehicle is relatively fixed, on the basis of measuring the required amount of supplementary electricity in kilowatt-hours, it is also possible to add a percentage of the target vehicle's battery power to intuitively represent the supplementary electricity. In addition, it should also be considered that the percentage calculation of battery charging for different target vehicles is not average. For example, the amount of electricity supplemented when the target vehicle's power increases from 10% to 20% may be more than the amount of electricity increased from 20% to 30%. Therefore, taking all factors into consideration, using kilowatt-hour measurement is the most accurate statistical method.

[0070] The charging completion time point can obviously intuitively reflect the expected charging completion time, and the charging completion time point can also be converted by the charging duration. For example, the target vehicle needs to complete 50% of the target vehicle's electricity replenishment within 1 hour, or, at 16:00, the target vehicle is expected to replenish 50% of its electricity at 17:00.

[0071] The user may initiate a charging request when the vehicle's battery is running out of power. This situation can be understood as an immediate request, that is, the user needs a charging car to provide charging services for him in a short period of time. At this time, the maximum power required by the target vehicle may be close to 100% of the power that its on-board battery can store. The user may also initiate a charging request when the vehicle still has some power remaining. In this case, the charging request is divided into two types. One is an appointment request: replenishing power at the time when the power is expected to be exhausted; the other is an immediate request: in a short period of time, although the power has not been exhausted, in order to ensure long-distance travel, the power needs to be fully charged immediately. At this time, the maximum power required is far less than 100% of the battery capacity. Therefore, according to the above different situations, there are different specific charging requirements, which have a certain impact on the selection of charging cars in subsequent steps.

[0072] Step S102: determining an optional charging cart according to the charging type.

[0073] This step is used to determine the charging vehicle that matches the charging type of the target vehicle. Corresponding to the charging method of the above-mentioned target charging vehicle, the charging vehicles are generally divided into the following types:

[0074] 1. Slow charging cart: This type of charging cart uses standard household power equipment to output stored electrical energy and is suitable for daily low-mileage vehicle charging.

[0075] 2. AC public charging car: This charging car is usually equipped with AC charging equipment and can reach the designated location to charge electric vehicles when needed. The charging speed is slow. This charging method is suitable for general daily charging needs, such as temporary charging needs in parking lots, residential areas or commercial areas.

[0076] 3. DC fast charging car: DC fast charging car is equipped with high-power DC charging equipment, which can quickly charge electric vehicles. This charging method is suitable for situations where fast charging is urgently needed, such as charging during long-distance travel, and rescue charging when the electric vehicle battery is about to run out.

[0077] Determining the optional charging cart according to the charging type includes at least one of the following methods: determining the optional charging cart corresponding to the charging interface according to the type of the charging interface of the target vehicle. The charging cart determined according to the charging type of the target vehicle is used as an optional charging cart. In theory, these optional charging carts can provide charging services for the target vehicle. However, since the target vehicle often has certain requirements for the amount of supplementary electricity, it is also necessary to count the amount of supplementary electricity that the charging cart can provide on this basis.

[0078] Step S103, obtaining the current power status of each optional charging cart. Since the working process of the charging cart requires that sufficient electric energy be pre-stored in its own battery, and then the stored electric energy is delivered to the target vehicle. Therefore, the current stored power of the charging cart determines the ability to charge the target vehicle, that is, the more power the charging cart has, the more power it can provide to the target vehicle, and the less power the corresponding charging cart has, the less power it can provide to the target vehicle. Therefore, it is necessary to obtain the current power status of the optional electric cart to further determine whether it can meet the charging needs of the target vehicle.

[0079] The current power status of the optional charging cart includes one or more of the following parameters: the current stored power of the optional charging cart, the current stored power cost, whether recharging is in progress, the estimated time to complete recharging, and the estimated stored power cost when recharging is completed.

[0080] The current stored electricity fee refers to the total fee for the electricity obtained from the charging pile (power source) during the process of the optional charging car reaching the current stored electricity. Whether the optional charging car is being recharged includes whether the optional charging car is in a recharging state and whether the optional charging car is in a non-recharging state. The estimated recharging completion time is the time required for the charging car to complete the recharging process, which means that the stored electricity of the charging car reaches a specified state, such as full. The estimated storage electricity fee when recharging is completed includes the fee consumed for recharging the current stored electricity when the optional charging car completes the recharging, calculated based on the estimated recharging time and the recharging electricity.

[0081] During the charging process of the charging car, since the power grid electricity charges different electricity prices at different stages of the peak and valley, the charging car needs to pay different electricity charges for performing the charging operation at different times; from the perspective of the power grid's peak shaving and valley filling, the difference in electricity prices can encourage users to use electricity as low as possible from an economic perspective, thereby achieving the overall balance of the power grid; the charging car of this application, as a transition link between the power grid and the charging of new energy vehicles, can perfectly realize the supply of valley electricity to new energy vehicles that need to be charged in other time periods, realize the time allocation between the demand for new energy charging and the power grid valley power supply, so that new energy vehicle users can enjoy the economic benefits of low electricity prices during valley periods during non-valley periods. To this end, the electricity price when the charging car charges the new energy vehicle needs to correspond to the electricity price of the electricity obtained when it is replenished; considering that the charging car is likely to use different prices of power grid power supply at different times when replenishing energy, when the charging car charges the new energy vehicle, the charging cost of the charging car should be considered, and the corresponding price strategy and price calculation method should be adopted.

[0082] For example, according to the first-in-last-out principle, different external charging prices correspond to the electricity of the charging car at different power stages, and when there is a charging request, the power supply price for new energy vehicles is calculated according to the first-in-last-out or first-in-first-out principle; or, based on the total electricity cost consumed by the charging car to obtain energy replenishment, the average price per kilowatt-hour is calculated as a whole, which is used as the power supply price when responding to a charging request; or, based on the total electricity cost consumed by the charging car to obtain energy replenishment, and according to the scarcity of the optional charging car within the charging time selected by the target vehicle, a corresponding scarcity coefficient is set according to the scarcity as a cost adjustment standard, and the total electricity cost consumed by the charging car to obtain energy replenishment is multiplied by the scarcity coefficient to obtain the external charging price after cost adjustment.

[0083] Step S104, determining the optional charging time period and charging fee of each optional charging vehicle that can charge the target vehicle according to the current power status of each optional charging vehicle and the required supplementary power of the target vehicle.

[0084] This step is used to obtain the optional charging time period and charging fee of each optional charging vehicle.

[0085] Through step S102, some optional charging carts are determined. In addition, the optional charging time that the charging cart can provide services for users and the corresponding charging costs are also important factors for users to consider when choosing a charging cart. Therefore, in this step, based on the aforementioned optional charging carts, according to the current power status of the acquired rechargeable cart and the required supplementary power of the target vehicle, the time and corresponding cost of the optional charging cart that can provide charging services for the target vehicle are determined. At the same time, the optional charging time period and charging cost are also the main basis for the recommended sorting of the optional charging carts.

[0086] Please see Figure 2 , Figure 2 A flow chart of a method for determining the optional charging time period and charging fee of a charging cart provided in the first embodiment of the present application. The method of determining the optional charging time period and charging fee of each optional charging cart that can charge the target vehicle according to the current power status of each optional charging cart and the required supplementary power of the target vehicle includes steps S201 to S206.

[0087] Step S201, based on the conversion relationship between the stored power of the optional charging cart and the supplementary power of the target vehicle, determine whether the current stored power of the optional charging cart can meet the required supplementary power of the target vehicle.

[0088] This step is used to determine whether the current stored power of the optional charging cart meets the required supplementary power of the target vehicle. Most energy transmission processes will cause losses. When the optional charging cart replenishes power for the target vehicle, there is a process of power transmission, which will cause power loss, making it likely that the power released from the charging cart cannot be fully input to the target vehicle. Therefore, the conversion relationship that can be obtained in this step estimates the degree of match between the current charging cart and the supplementary power of the target vehicle, that is, whether the stored power of the optional charging cart meets the charging needs of the target vehicle.

[0089] Step S202: If the condition is satisfied, the optional charging time period during which the optional charging vehicle can charge the target vehicle is determined to be now, and the charging cost for completing the target charging demand is determined based on the current stored electricity cost.

[0090] This step is used to determine the charging cost.

[0091] Since the billing of the power grid generally has low-price time periods and high-price time periods, the power grid fees generated may be different when the charging time of the charging car is different, even if the amount of electricity replenished is the same. Ideally, the charging car replenishes energy during the low-price time period, and stops replenishing energy during the high-price time period and charges the target vehicle, which can achieve the lowest cost. Therefore, it is necessary to count the charging time and cost of the charging car. According to the billing method of the power grid at different times and the time of the charging car replenishing energy, the cost of the charging car replenishing energy is determined, and then the cost of the target vehicle using the charging car to charge is determined; the specific calculation of the charging cost of the charging car needs to be calculated based on the cost of obtaining electricity during its replenishment stage, combined with the pricing method of charging new energy vehicles; in order to encourage the use of valley electricity, as mentioned above, various pricing strategies can be set for its charging stage.

[0092] According to step S201, available charging carts that meet the target vehicle's power replenishment requirements are screened out, and among these available charging carts, the one that meets the requirement of instantly charging the target vehicle is determined, and based on the determined result and the current storage power cost of the optional charging cart, the charging cost required to charge the target vehicle is determined.

[0093] The available charging cart obtained according to this step can be used as the charging cart that best meets the user's requirements. However, during the peak period of charging cart use, it may not be possible to provide a sufficient number of charging carts that fully meet the charging needs of the target vehicle. In this case, in order to provide the user with the charging cart that best meets the charging needs of the target vehicle among all charging carts as much as possible, a reasonable replacement solution is provided to the user by indirectly meeting the charging needs of the target vehicle. The replacement solution can be to wait for the available charging cart that is being recharged to complete the recharging, at which time the stored electrical energy can meet the charging needs of the target vehicle.

[0094] Step S203: If the condition cannot be met, query the current power status parameters of the optional charging vehicle to confirm whether it is being recharged.

[0095] This step determines the energy replenishment status of the optional charging vehicles remaining after the screening in step S202. This step can provide an estimation method for the subsequent estimated energy replenishment completion time of the available charging vehicles.

[0096] If the power storage of the optional charging carts cannot meet the charging needs of the target vehicle, it indicates that the power storage of all the currently available charging carts is too low. By querying the current power status parameters of all currently available charging carts, the status parameters include whether the optional charging carts are being recharged and whether they are not being recharged, confirm whether the optional charging carts are being recharged. For the charging carts that are being recharged, you can wait until their stored power reaches a certain requirement and then assign them to the corresponding target vehicle to perform the charging task. At this time, the user needs to be informed of the waiting time and the estimated recharging cost.

[0097] Step S204: If yes, then obtain the estimated completion time of energy replenishment and the estimated storage power cost when energy replenishment is completed. The estimated completion time of energy replenishment refers to the time required for the storage power of the available charging vehicle to meet the target vehicle energy replenishment power requirement.

[0098] Step S205, determining the energy replenishment cost required for charging the target vehicle according to the estimated stored electricity cost when the energy replenishment is completed.

[0099] Step S206, according to the estimated energy replenishment completion time, determine that the optional charging time period during which the optional charging cart can charge the target vehicle is after the estimated energy replenishment completion time. For safety reasons, the charging cart in the energy replenishment state cannot directly provide charging services for the target vehicle. At the same time, the charging cart in the energy replenishment state indicates that once the energy storage of the charging cart reaches the required standard, it can be put into normal use.

[0100] In an optional implementation, the estimated energy replenishment completion time includes: the time required for the optional charging vehicle to be fully charged, or the time required for the energy replenishment power of the optional charging vehicle to meet the required replenishment power of the target vehicle;

[0101] The estimated cost of stored electricity when the energy replenishment is completed includes: the corresponding cost of fully charging the optional charging cart, or the corresponding cost of the optional charging cart's energy replenishment to meet the replenishment power required by the target vehicle; the corresponding cost of the charging cart is calculated based on the grid power supply cost when it obtains energy replenishment.

[0102] By executing the above steps, the available charging time and charging cost of the optional charging car can be obtained. The above steps provide a technical basis for improving the utilization rate of electric energy and controlling the electricity cost for the charging car.

[0103] Step S105, determining the optional target charging vehicles and their order that can meet or at least partially meet the charging requirements of the target vehicle according to the optional charging time period and corresponding fees of the charging vehicle and the charging completion time point required by the target vehicle.

[0104] This step is used to determine the order of charging vehicles that can provide charging services according to the needs of the target vehicle.

[0105] The optional charging time periods and corresponding fees of the charging carts have been obtained. The information of these charging carts needs to be matched with the charging demand information of the target vehicle so that the charging carts can be arranged in a targeted and sequential manner to select the charging cart with a higher matching degree.

[0106] In one embodiment, the determining and sequencing of optional target charging vehicles that can meet or at least partially meet the charging needs of the target vehicle, wherein the optional target charging vehicle that meets the charging needs of the target vehicle can charge the required supplementary power at the required charging completion time point;

[0107] The optional target charging cart that at least partially meets the charging needs of the target vehicle can complete part of the required supplementary electricity within the required charging completion time point and at least reach a preset minimum power threshold, or can charge the required supplementary electricity within a grace period of time later than the charging completion time point.

[0108] In one embodiment, in the determining and sorting of optional target charging vehicles that can meet or at least partially meet the charging requirements of the target vehicle, the sorting includes at least one of the following methods:

[0109] Sort by the time required to complete the required replenishment;

[0110] Sort by the corresponding cost required to complete the required replenishment of electricity;

[0111] The target vehicles are sorted according to the amount of electricity that can be replenished for them when the charging is completed.

[0112] The charging-related data of the optional charging carts after sorting are clearer and more orderly, and more suitable charging carts can be quickly selected and deployed according to the needs of the target vehicle and the charging needs of other vehicles on site, reducing the waiting time in the charging queue and increasing the speed of selecting the charging cart.

[0113] Step S106, referring to the ranking, selecting a target charging vehicle from the optional target charging vehicles.

[0114] This step is used to select the target charging vehicle that best matches the target vehicle based on the charging demand information of the target vehicle. The selection process can be performed by the system background after selection, or an interactive interface can be set for the user to select and determine the target charging vehicle independently.

[0115] In one embodiment, more than one charging cart can be used to charge a target vehicle. This method is generally not preferred. When there is no charging cart that meets or approaches the charging requirements of the target vehicle, this method can be used to provide the user with the best charging strategy in this case. The recommendation method of the charging cart also includes: when each of the optional charging carts cannot meet the required supplementary power and the required charging completion time of the target vehicle, multiple charging carts are called to relay to charge the target car to meet the required supplementary power and charging completion time requirements of the target vehicle. In this process, each charging cart communicates with each other or through the system background to achieve coordination, and combines the charging requirements of other target vehicles to reduce the idle time (non-recharging and non-charging time) of each charging cart as much as possible. Specifically, the storage power of all optional charging carts is sorted, and the charging cart with the highest storage power is preferentially selected to charge the target vehicle. At this time, other charging carts should be in a replenishing state for subsequent use. Assuming that the battery capacity of the charging car is equal to that of the target vehicle, and the conversion ratio is even, and there is no loss during the power transmission process, then when the target vehicle needs to be charged 80%, the current power state of the optional charging cars is less than 80%, and no charging car can reach 80% of the storage power in a short time. At this time, the relay scheduling method can be used to charge the target vehicle. The highest storage power among the optional charging cars is 60%. In addition, one or more charging cars with a total storage power of 20% are selected as the second target charging car for charging. If there is no second target charging car that meets the conditions, the time when the charging car charges the target vehicle can be further associated with the time when the charging car replenishes energy. If when the target vehicle consumes 60% of the charging capacity, there is one or more storage batteries with a total storage power of 20%, then the relay scheme can still be used to select a suitable charging car to charge the target vehicle. It is worth noting that in the above example, it is assumed that only one target vehicle needs to be charged during the entire process. However, in actual applications, the charging needs of other target vehicles should also be taken into consideration. The charging needs of each charging cart and the target vehicle should be comprehensively considered, and the appropriate charging carts should be reasonably allocated to each of them to achieve efficient use of charging cart resources.

[0116] The charging cart recommendation method provided in this embodiment determines the optional charging cart according to the charging type of the target vehicle, and then reasonably divides the available time of the charging cart according to the status of the charging cart, and combines the charging demand of the target vehicle so that there is a specific correspondence between the charging demand of the target vehicle and the charging cart, thereby avoiding the problem of chaotic charging cart allocation mechanism and low allocation efficiency. This embodiment also determines the optional target charging carts and their ranking that can meet or at least partially meet the charging demand of the target vehicle based on the optional charging time period and corresponding fees of the charging cart and the charging completion time point required by the target vehicle; associates the charging cost of the charging cart with the charging fee required by the target vehicle, providing a billing idea for the operation and management of the charging cart. At the same time, referring to the ranking, the target charging cart is selected from the optional target charging carts, which further intuitively improves the efficiency of selecting the charging cart and also provides users with the right to choose the charging cart independently.

[0117] Second embodiment

[0118] Based on the recommended method for the charging cart provided in the first embodiment of the present application, the second embodiment of the present application provides a charging method for the charging cart. For related content, please refer to the description of the first embodiment.

[0119] Please see Figure 3 , Figure 3 The flowchart of the charging method for the charging cart provided in the second embodiment is shown in FIG. The charging method for the charging cart provided in this embodiment includes steps S301 to S305.

[0120] Step S301, the charging car selected in the optional target charging car list is used as the target charging car. This step can be provided to the user through an interactive interface, and the user selects and confirms, or the selection and confirmation can be made through a management platform.

[0121] Step S302, obtain the trigger operation of confirming the target charging car, control the target charging car to charge the target vehicle, and obtain the start time of use. After confirming the selected target charging car, the charging car is immediately in working state, and the time of starting to use the charging car can be counted at this time.

[0122] Step S303, obtain a charging stop instruction, control the target charging vehicle to stop charging, and obtain the stop usage time. The charging stop instruction can be initiated by the user through the interactive page, or it can be forced to be interrupted due to other reasons. In short, as long as charging is eventually stopped, the usage time should be stopped at this time.

[0123] Step S304, obtaining the charging time of the target vehicle according to the start time and the stop time. Usually, the charging vehicle and the system can generate the charging time of the target vehicle by counting the start time and the stop time.

[0124] Step S305, settle the charging fee according to the charging time and pricing rules. Charging time is an important factor in charging costs. Generally, the longer the charging time, the more electric energy is replenished, and the probability that other target vehicles can use the charging car will become lower. Therefore, the longer the charging time, the greater the corresponding cost, but it is not a straight-line growth. In the actual process, the specific selected charging type and the total electric energy obtained will also be considered. Preferably, the charging cost required for the target vehicle can be calculated in total based on the energy replenishment cost of the electric energy currently stored in the charging car. Of course, the calculation of charging costs is not limited to the methods and factors described above. Only by adjusting in time according to actual conditions can reasonable charging costs be obtained. For details, please refer to the relevant description of the first embodiment.

[0125] In one implementation, the pricing rules include:

[0126] Determine the charge for the target vehicle according to the cost of the electricity stored when the target charging vehicle completes the energy replenishment;

[0127] The cost of electricity stored in the target charging car when the target charging car completes energy replenishment is calculated based on the real-time electricity price of the power grid when the target charging car is replenished, and the corresponding cost of the current stored electricity of the target charging car is calculated.

[0128] In one implementation, the pricing rules further include:

[0129] According to the time period when the target vehicle requests charging, the number of optional charging carts within the time period is obtained, the scarcity of the optional charging carts within the charging time selected by the target vehicle is determined, and corresponding fee adjustment standards are set according to the scarcity.

[0130] The scarcity can be understood as the number of available charging carts when the current target vehicle needs to be charged. If the number of available charging carts that meet the conditions is large at this time, it indicates that the scarcity of the optional charging carts is low at this time; on the contrary, if the number of available charging carts that meet the conditions is small, it indicates that the scarcity of the optional charging carts for testing is high. Under normal circumstances, when the scarcity is low, the probability of waiting in line is small, the number of charging carts that need to be dispatched is small, and most of the charging carts are idle at this time. If they are not used for a long time, the electric energy will be lost in vain. At the same time, considering that the electric energy on the power grid is output all the time, if there is no charging cart that needs to be replenished, the electric energy output on the power grid is also wasted. Therefore, when the scarcity is low, the price of charging is relatively low; on the contrary, when the scarcity is high, the price of charging is relatively high.

[0131] The charging method for the charging cart provided in the second embodiment of the present application calculates the fee based on the charging time, type, etc., and also combines the different characteristics of the grid billing rules and the changes in the scarcity of charging carts to refine the charging method for the charging cart. This method can be used to clearly, reasonably and efficiently calculate the fee information and cost information of the charging cart.
