Description

Technical Field

[0001] This specification relates to the field of vehicle charging, and in particular to a vehicle timed charging method and system. Background Art

[0002] Currently, new energy vehicles are widely used in public transportation. They are primarily charged via charging stations at various charging stations. For operational fleets, such as bus fleets and construction fleets, there's a need to charge multiple vehicles simultaneously, requiring high charging power. However, typical charging stations have a maximum safe load, making it difficult to meet this demand. Manual batch charging also presents challenges such as cumbersome operation and long charging times. Furthermore, charging for operational fleets often occurs during peak hours of electricity consumption, requiring on-site monitoring by personnel. This manual monitoring is inefficient and prone to errors.

[0003] Therefore, it is necessary to provide a vehicle timed charging method and system that can reasonably plan the vehicle charging plan. Summary of the Invention

[0015] To more clearly illustrate the technical solutions of the embodiments of this specification, the following briefly describes the drawings required for describing the embodiments. Obviously, the drawings described below are merely examples or embodiments of this specification. Those skilled in the art can apply this specification to other similar scenarios based on these drawings without inventive effort. Unless otherwise apparent from the context or otherwise noted, the same reference numerals in the figures represent the same structure or operation.

[0016] It should be understood that the terms "system," "device," "unit," and / or "module" used herein are a method for distinguishing different components, elements, parts, portions, or assemblies at different levels. However, if other terms can achieve the same purpose, the terms may be replaced by other expressions.

[0017] As used in this specification and claims, unless the context clearly indicates otherwise, the words "a," "an," "an," and / or "the" do not refer to the singular but also include the plural. Generally speaking, the terms "comprises" and "include" only indicate the inclusion of the steps and elements specifically identified, and these steps and elements do not constitute an exclusive list. A method or apparatus may also include other steps or elements.

[0018] Flowcharts are used throughout this specification to illustrate the operations performed by systems according to embodiments of this specification. It should be understood that preceding or following operations do not necessarily need to be performed in exact order. Instead, the steps may be processed in reverse order or simultaneously. Furthermore, other operations may be added to these processes, or one or more operations may be removed from these processes.

[0019] At present, most charging stations are dedicated to serving operating fleets (such as bus fleets, engineering fleets, etc.) during off-peak hours. For unified fleet management and cost considerations, operating fleets need to complete the charging of the entire fleet within a certain period of off-peak hours. However, there is a large power demand for charging the entire fleet at the same time, which is likely to exceed the maximum load of the charging station. In addition, most charging stations are unmanned stations, and manual on-site charging of operating fleets will incur large manpower costs, and the large fleet will lead to cumbersome operations and operational errors. The existing technology generally involves on-site staff manually charging each vehicle, or plugging the vehicle in for charging in advance. However, charging in advance cannot achieve unified management of the entire fleet, and manual on-site operation errors are inevitable. In view of this, the embodiments of the present application provide a vehicle timed charging method and system, which can be used in the fields of vehicle charging, charging station power management, and charging equipment management.

[0020] Figure 1 It is a schematic diagram of an application scenario of an exemplary vehicle timed charging system according to some embodiments of this specification.

[0021] like Figure 1 As shown, the application scenario 100 of the vehicle timed charging system may include a charging pile 110, a processing device 120, a terminal device 130, a storage device 140, and a network 150. In some embodiments, the processing device 120 may be a part of the charging pile 110.

[0022] The charging pile 110 is used to provide electrical energy for the vehicle. A charging station may include multiple charging piles, and each charging pile may include multiple charging guns. The charging gun can charge a certain vehicle. The power of the charging pile can be 7KW, 15KW, 30KW, 45KW, 60KW, 90KW, 120KW, 180KW, 240KW, 360KW, etc. In some embodiments, the charging pile may include a DC charging pile and an AC charging pile. It should be noted that the charging piles involved in this specification can be replaced with charging guns for description without causing confusion. Charging piles and charging guns can be used as the minimum unit for management of the vehicle timed charging method provided in this specification.

[0023] The processing device 120 can process data and / or information obtained from the charging station 110, the terminal device 130, the storage device 140, or other components of the system application scenario 100. For example, the processing device 120 can obtain the status of the charging gun from the charging station 110, such as whether the charging gun is in use, and analyze and process the information. For another example, the processing device 120 can obtain a target scheduled charging plan for the charging station, which includes at least one charging station to be activated; determine a charging station activation sequence based on the status of the charging gun on the at least one charging station to be activated; determine the available power of the charging station; and activate one or more charging stations in the charging device activation sequence in batches based on the available power and a preset first algorithm. In some embodiments, the processing device 120 can be local or remote. For example, the processing device 120 can access information and / or data from the charging station 110, the terminal device 130, and / or the storage device 140 via the network 150.

[0024] The terminal device 130 may be a terminal operated by a user. The terminal device 130 may implement the input of user instructions and operations, or the output of information such as charging status. In some embodiments, the user may input a request to obtain the available power of the charging station through the terminal device 130. In this specification, "user" and "user terminal" may be used interchangeably. In an embodiment of the present invention, the terminal device 130 may include a mobile device 130-1, a tablet computer 130-2, a laptop computer 130-3, etc. or any combination thereof. In some embodiments, the terminal device 130 may be integrated into the charging pile 110, that is, the two may implement all functions as a whole. In this specification, the user may be an on-site staff member, a driver, etc.

[0025] The storage device 140 may store data, instructions, and / or any other information. In some embodiments, the storage device 140 may store data obtained from the charging station 110 and / or the processing device 120, such as the status of the charging gun.

[0026] In some embodiments, the storage device 140 may include one or more storage components, each of which may be a standalone device or part of another device. In some embodiments, the storage device 140 may include random access memory (RAM), read-only memory (ROM), mass storage, removable memory, volatile read-write memory, or any combination thereof. Exemplary mass storage may include a magnetic disk, an optical disk, a solid-state disk, or the like. In some embodiments, the storage device 140 may be implemented on a cloud platform.

[0027] Network 150 may comprise any suitable network capable of facilitating information and / or data exchange. In some embodiments, at least one component of vehicle timed charging system application scenario 100 (e.g., charging station 110, processing device 120, terminal device 130, storage device 140) may exchange information and / or data with at least one other component of the system application scenario 100 via network 150. For example, processing device 120 may obtain charging gun status from charging station 110 via network 150.

[0028] It should be noted that the application scenario 100 of the vehicle timed charging system is provided for illustrative purposes only and is not intended to limit the scope of this specification. A person skilled in the art would be able to make various modifications or variations based on the description of this specification. For example, the application scenario 100 of the vehicle timed charging system may also include a database. For another example, the application scenario 100 of the vehicle timed charging system may implement similar or different functions on other devices. However, such variations and modifications would not deviate from the scope of this application.

[0029] Figure 2 FIG2 is a flow chart of an exemplary vehicle timed charging method according to some embodiments of this specification. In some embodiments, process 200 may be executed by a processing device (eg, processing device 120). Figure 2 As shown, process 200 may include the following steps:

[0030] Step 210: Obtain a target scheduled charging plan for the charging station.

[0031] A charging station is a facility that provides charging services for vehicles (such as electrically powered vehicles). In some embodiments, a charging station may include multiple charging piles, each of which may include one or more charging guns. Each charging pile can charge one or more vehicles simultaneously, and each charging gun can charge a specific vehicle. For ease of management, each charging pile can be numbered, such as 1, 2, etc.; further, each charging gun can be numbered, such as 1A, 1B, etc. The number can serve as a unique identifier for the charging pile or charging gun for easy identification.

[0032] The target timed charging plan is a preset charging scheme for the vehicle to be charged. In some embodiments, the target timed charging plan includes at least one charging pile to be started. For example, after the vehicle to be charged is connected to each charging pile through a charging gun, the target timed charging plan may include the activation time of each charging pile (or each charging gun), and the number of the specifically enabled charging pile (or charging gun). For example, the target timed charging plan may be to start the charging guns 1A, 1B, and 1C from 22:00 to 03:00. In some embodiments, the target timed charging plan also includes electricity price billing. Since there are differences in electricity prices due to different charging times, the electricity price of the charging time period can be determined based on the time in the target timed charging plan by the preset time-electricity price relationship, and the electricity demand can be determined by the number of the specifically enabled charging pile (or charging gun). The multiplication of the two is the charging price billing.

[0033] The charging gun status can be enabled or disabled. Enabled indicates charging is in progress, while disabled indicates not charging. The disabled status of a charging gun can further include "plugged in, not charging," "unplugged," and so on. It should be noted that the smallest unit managed in a target scheduled charging plan can be a charging pile or a charging gun. When the smallest unit is a charging pile, enabling or disabling the charging pile indicates enabling or disabling all charging guns connected to that charging pile.

[0034] In some embodiments, the processing device 120 may obtain all scheduled charging plans of the vehicle station; determine a target scheduled charging plan from all scheduled charging plans based on preset plan conditions; wherein the preset plan conditions include at least one of the following: time conditions, billing conditions, or location conditions.

[0035] In some embodiments, all scheduled charging plans for a vehicle station may be pre-stored in the storage device 140 or other databases. The processing device 120 may retrieve all of the aforementioned scheduled charging plans and compare them with preset plan conditions to screen the plans, and determine the scheduled charging plans that meet the preset plan conditions as target scheduled charging plans.

[0036] The preset plan conditions are screening conditions set for the scheduled charging plan. Based on the different actual conditions of each charging (such as the different on-site time of the fleet each time, the different number of vehicles in the fleet, and the different numbers of charging guns connected to the vehicles), the preset plan conditions can be adjusted according to the actual situation. Among them, the time condition can be a time requirement for the charging plan. For example, the on-site time of the fleet is different each time, and different requirements are made on the charging time period of the vehicle. The billing condition is the billing requirement for the charging plan. For example, for cost considerations, it is necessary to choose a time period with low electricity prices such as off-peak hours for charging. The location condition can be the numbering requirement for charging piles and charging guns. For example, if the fleet is charging in adjacent areas, the charging piles and charging guns need to be consecutive numbers and be in adjacent locations, so that it is convenient for drivers or station staff to manage them in a unified manner. In some embodiments, the preset plan conditions can be determined by manual settings, automatic settings by artificial intelligence, etc.

[0037] Step 220 : Determine a charging pile startup sequence based on a charging gun status of at least one charging pile to be started.

[0038] The charging pile startup sequence reflects the order in which the charging piles are started. In some embodiments, the charging pile startup sequence can be a charging pile number sequence, for example, No. 1, No. 3, No. 5, No. 2, No. 4, etc., and the numbering sequence represents the startup order of the charging piles.

[0039] In some embodiments, the processing device 120 may determine the number of charging guns that are not charged at each charging pile in the target timed charging plan; sort the charging piles according to the number of charging guns, and determine a startup sequence for the charging piles.

[0040] In some embodiments, the processing device 120 can determine the status of the charging gun on each charging pile to be started through feedback from the charging pile. For example, the charging pile can count the number of uncharged plug-ins of its charging gun and feed it back to the processing device 120. The processing device 120 can determine the number of uncharged plug-ins of the charging gun on each charging pile to be started based on this. It can be understood that the more uncharged plug-ins there are, the more uncharged vehicles are connected to the charging pile, and the system can give priority to charging the vehicles connected to the charging pile. In some embodiments, the charging piles can be sorted according to the number of uncharged plug-ins of the charging pile, that is, sorted from large to small according to the number of uncharged plug-ins.

[0041] Step 230: Determine the available power of the charging station.

[0042] Available power is the power that a charging station can use to provide to a vehicle to be charged. Available power can be the idle power in the charging station.

[0043] In some embodiments, the processing device 120 can obtain the maximum allowable power and real-time used power of the charging station; based on the maximum allowable power and real-time used power, the available power is determined by a preset second algorithm. The maximum allowable power of the charging station can be determined by the planning value preset during the construction of the charging station. In actual operation, the maximum allowable power can be slightly less than the maximum power of the charging station. When the actual power used is greater than the maximum allowable power but less than the maximum power, there will be a safety hazard. Therefore, the maximum power of the charging station can be manually lowered by a certain value as the maximum allowable power of the charging station. The real-time used power can be determined by taking statistics on the charging piles used.

[0044] The preset second algorithm may be an algorithm for calculating available power. As an example only, available power may be calculated using the following formula (1): Among them, P a is the available power; P s is the maximum allowable power of the charging station; θ is the safety power margin (a coefficient of 0 to 1, which can be set to 0.9 based on experience); P c The power of the charging gun during charging at the time when the timing starts; It is the real-time power used by the entire station. It should be noted that the power of the charging gun is not constant during the charging process. c It can be expressed as the moment with the highest power in the entire charging process (generally, the power of the charging gun is the highest when it is started), which can ensure the security of the algorithm.

[0045] Step 240 : Based on the available power and a preset first algorithm, one or more charging piles in the charging device startup sequence are started in batches.

[0046] The preset first algorithm is an algorithm for calculating the startup sequence of charging piles. Since the maximum allowable power of the charging station may be lower than the power requirement for all vehicles to be charged in the fleet to be charged at the same time, the processing device 120 can control the charging piles to start in batches to charge all vehicles to be charged. In the process of controlling the startup of charging piles in batches, it is necessary to consider that each batch can maximize the use of the power of the current charging equipment, and it is also necessary to ensure that the power required for the charging process is always below the maximum allowable power. By preset the first algorithm, it can be determined how many batches are required for the charging process and which numbered charging piles are required for each batch of the charging process. For example, the processing device can calculate the number of charging devices that can be started in the first batch based on the available power and the preset first algorithm; thereafter, when the available power is updated, the processing device can calculate the number of charging devices that can be started in the second batch based on the latest available power and the preset first algorithm; multiple calculations can be performed to determine the number of charging devices that can be started in each subsequent batch, thereby improving the efficiency of vehicle timed charging while ensuring that the entire charging process does not exceed the maximum output power allowed by the station. For a detailed description of the preset first algorithm, see Figure 3 and its related descriptions.

[0047] In some embodiments of this specification, a vehicle timed charging system and method can be used to implement batch charging in a fleet timed charging scenario; this can maximize the protection against overload and power outages at the station, and can also maximize the utilization rate of the station's charging equipment; the above process is implemented through system calculations, avoiding the workload and errors caused by manual operation.

[0048] It should be noted that the above description of process 200 is for illustration and purpose only and does not limit the scope of this specification. Those skilled in the art may make various modifications and alterations to process 200 under the guidance of this specification. However, such modifications and alterations remain within the scope of this specification. For example, process 200 may include a pre-processing step.

[0049] Figure 3 FIG3 is a flowchart of an exemplary method of starting a charging device according to some embodiments of this specification. In some embodiments, process 300 may be executed by a processing device (eg, processing device 120). Figure 3 As shown, process 300 may include the following steps:

[0050] Step 310 : Based on the maximum output power and available power of the charging station, determine a first number of startable charging piles in the first batch using a preset first algorithm.

[0051] The maximum output power is the maximum allowable power of the charging station, that is, the maximum power that can ensure charging safety. For example, the maximum output power can be 1000KW, 5000KW, etc.

[0052] The first quantity is the number of charging piles started in the first batch, for example, 10, 15, etc.

[0053] As an example only, the first number of charging piles started can be calculated using the following formula (2): P a -X*P e >0 (2)

[0054] Wherein, X is the first number, i.e. the maximum number of charging piles that can be started, and X is a positive integer; P e is the maximum output power of each charging pile, which can be determined by the factory preset value of the charging equipment. Formula (2) can be used to determine the maximum number of charging piles that can be started under the current available power. It is understandable that there is still unused available power after only starting X charging piles, so the rational utilization of available power can be achieved through subsequent multi-round algorithms.

[0055] Step 320: Based on the first quantity, start a first number of charging piles in the charging pile sequence and update the charging pile start sequence.

[0056] The first number of charging piles in the startup sequence are started in the order in which they are ranked. For example, if the startup sequence is 1, 3, 5, 2, 4, and so on, and the first number is 4, then charging piles 1, 3, 5, and 2 can be started in the first round of calculation (i.e., the first batch).

[0057] In some embodiments, updating the charging pile startup sequence may be updating the charging pile ranking, for example, deleting the already started charging piles (such as the above-mentioned charging piles No. 1, No. 3, No. 5, and No. 2) from the charging pile startup sequence.

[0058] Step 330: Start the subsequent batches of charging piles. The following steps are executed in a loop to start the subsequent batches of charging piles:

[0059] Step 331: Obtain the latest available power of the charging station.

[0060] In some embodiments, the processing device 120 may obtain the new available power through calculation.

[0061] In some embodiments, the processing device 120 may further monitor the status of a charging gun on a charging pile of the charging station; and determine the latest available power of the charging station in response to monitoring that a charging gun stops charging.

[0062] During the charging process, there may be a situation where other vehicles have completed charging. In this case, the power quota allocated to the vehicle can be returned to the available power, which can be calculated by formula (3);

[0063] in, is the latest available power after update; m is the number of charging guns that stopped charging, which can be determined through feedback from the charging pile. In some embodiments, for each round of calculation, the processing device 120 can use the above formula (3) to update the available power to achieve maximum available power utilization.

[0064] Step 332: Based on the latest available power, determine the second number of startable charging piles using a preset first algorithm.

[0065] After the X charging piles are started and the charging power is stabilized after 5-10 minutes, the second round of calculation can be performed using formulas (4) and (5): P a '-X'*P e >0 (5) Among them, P a ' is the available power in the second round; X' is the number of charging piles that can be started in the second round. As an example only, the charging pile startup sequence is No. 1, No. 3, No. 5, No. 2, No. 4... If X is 4, then charging piles No. 1, No. 3, No. 5, and No. 2 can be started in the first round of calculation (i.e., the first batch); then, based on the remaining available power in the second round of calculation, it is determined whether charging pile No. 4 can be started in the second batch. It can be understood that formula (4) is similar to formula (2), and similar logic is used to obtain the number of charging piles in the corresponding batch.

[0066] Step 333: Start a second number of charging piles in the updated charging pile sequence and update the charging pile sequence.

[0067] The startup process of the second batch of charging piles is performed based on the updated sequence of the first batch of charging piles, and the startup process is similar to the startup of the first batch of charging piles in step 320 above.

[0068] In some embodiments, updating the charging pile sequence may be updating the charging pile ranking, for example, deleting the already started charging pile from the charging pile sequence.

[0069] It is understood that the first algorithm may also include a third round of calculations, a fourth round of calculations, and so on. That is, steps 331, 332, and 333 in the first algorithm may be multiple cycles, and after step 333 is executed, the algorithm may return to step 331 for execution. This specification does not limit the number of cycles. In some embodiments, the conditions for stopping the cycle may include: all vehicles in the fleet are charged, the current available power is insufficient to charge a single vehicle, the computational load reaches the hardware functional limit, all charging piles at the charging station are in use, etc.

[0070] In this embodiment, the multiple rounds of calculations performed by the first algorithm can maximize the use of available power and ensure that the charging process is safe and efficient. In addition, the number of rounds of the first algorithm can be customized according to user needs, ensuring that the algorithm can be adaptively adjusted according to the actual conditions of the charging station and the fleet.

[0071] Figure 4 It is a schematic diagram of the data configuration stage according to some embodiments of this specification.

[0072] The data configuration phase can be a pre-processing (pre-installation) process for scheduled vehicle charging. Before scheduled vehicle charging, it is necessary to obtain information related to the charging station, charging equipment, and fleet vehicles in advance. After integrating and verifying this information, the normal scheduled vehicle charging process can be carried out.

[0073] In some embodiments, the data configuration stage includes fleet identity information configuration 410. In the fleet identity information configuration, the vehicle (or driver) identity can be verified by the VIN code. The VIN code can be a unique identifier for the vehicle. The VIN codes of each vehicle in the fleet can be pre-bound in the charging station, and the fleet identity information configuration can be achieved through remote verification. As an example only, 1 fleet can correspond to n1 VIN codes, of which n1 VIN codes can be assigned to each vehicle to be charged in the fleet. And 1 charging station can serve n2 fleets. The above n1 and n2 are arbitrary positive integers.

[0074] In some embodiments, the data configuration stage includes the station load information configuration 420. In the station load information configuration, it is necessary to determine the maximum output power of the charging station, the maximum output power of a single charging pile, and the output power of a single charging gun. Among them, the maximum output power of the charging station represents the maximum allowable power, and if it exceeds, an overload power outage occurs; the maximum output power of a single charging pile needs to be classified and configured according to the multi-specification charging piles of the station; the output power of a single charging gun is a dynamically changing value, which may change due to factors such as the battery specifications of the vehicle being charged, the current soc of the vehicle, whether there are other charging guns charging in parallel at the same charging pile, and the weather. As an example only, one charging pile may include n3 charging guns, and one charging station may include n4 charging piles. The above n3 and n4 are arbitrary positive integers.

[0075] In some embodiments, the data configuration stage includes configuring a station scheduled charging plan 430. In the station scheduled charging plan configuration, it is necessary to determine the activation time of each charging pile (or each charging gun), the number of the specifically enabled charging pile (or charging gun), and the electricity price billing. For example, charging piles No. 1 and No. 3 charge during valley time 03:00-22:00, and the electricity price billing is 0.3153 yuan / kWh, etc. As an example only, one charging station may include n5 scheduled charging plans. The above n5 is an arbitrary positive integer.

[0076] Figure 5 It is a schematic diagram of the batch timing start-up phase according to some embodiments of this specification.

[0077] like Figure 5 Step 510: traverse the scheduled start charging plan of the station.

[0078] Step 520: Screening for preset planning conditions, which may be time conditions, billing conditions, or location conditions.

[0079] Step 530: traverse the charging station charging gun status, sort them according to the number of uncharged guns, and obtain the charging pile startup sequence.

[0080] Step 540: Obtain the latest message data from the charging gun during charging and calculate the available power. The available power can be calculated using the first algorithm described above, which will not be described in detail here.

[0081] Step 550: Determine the remaining available power based on the first algorithm. If the queue of charging piles to be started is not empty, that is, there are still charging piles that need to be charged, then proceed to step 560 and execute step 580. If formula (2) is satisfied, then proceed directly to step 580. If there is a stopped charging device, then proceed to step 570 and return to step 530 to redetermine the available power.

[0082] Step 580: Determine a first number X of charging piles, start the first X charging piles based on the charging pile startup sequence, and update the sequence. Updating the sequence may include deleting the charging piles that have been charged in the charging pile startup sequence.

[0083] Figure 6 FIG is a block diagram of an exemplary vehicle timed charging system according to some embodiments of this specification. Figure 6 As shown, the vehicle timed charging system 600 includes an acquisition module 610 , a first determination module 620 , a second determination module 630 and a start module 640 .

[0084] An acquisition module 610 is configured to acquire a target scheduled charging plan of a charging station, wherein the target scheduled charging plan includes at least one charging pile to be started;

[0085] A first determining module 620 is configured to determine a charging pile startup sequence based on a charging gun status of the at least one charging pile to be started;

[0086] A second determining module 630 is configured to determine the available power of the charging station;

[0087] The starting module 640 is configured to start one or more charging piles in the charging device starting sequence in batches based on the available power and a preset first algorithm.

[0088] It should be noted that the above description of the system and its modules is for convenience of description only and does not limit this specification to the scope of the embodiments cited. It is understandable that for those skilled in the art, after understanding the principle of the system, it is possible to arbitrarily combine the various modules, or form a subsystem connected to other modules without deviating from this principle.
