Description

Technical Field

[0001] The present invention relates to the field of new energy charging technology, and in particular to a business mode control method based on orderly charging. Background Art

[0002] New energy electric vehicles are widely loved by the people due to their low carbon, environmental protection, and low cost. In particular, in recent years, new energy electric vehicles have become more and more popular, and they are likely to replace fuel vehicles. New energy electric vehicles are generally charged in the form of charging piles, and the charging piles are connected to the power supply network.

[0003] At present, there is a high overlap between the peak hours of new energy vehicle charging and ordinary residents' electricity consumption. If the current usage mode is maintained, the power supply network will face the problem of tight charging load. In order to solve this problem, the industry has proposed to expand and transform the power supply network. However, the actual expansion and transformation cost is high. Therefore, the industry mainly adopts several solutions that do not change the existing power supply network:

[0004] 1. Charging pile charging load balancing technology, that is, on the edge network of the charging pile, when the routing control center finds that the power supply network load is tight or surplus, it sends power adjustment instructions to the charging pile in real time, so that the charging pile increases or decreases the output power, and performs "peak shaving and valley filling" adjustment to ensure the power safety of the power supply network.

[0005] 2. Virtual power plant technology, that is, when the power supply network is under tight load, the power supply department sends instructions to reduce the output power of the charging piles, which is also a manifestation of "peak shaving and valley filling" of the power supply network.

[0006] 3. The orderly charging technology of traditional charging piles is to uniformly access a multi-phase power supply or a power supply with a larger distribution capacity, and use a large-scale master control device to transmit the current to multiple AC terminals in a load-balanced and sequential charging manner.

[0007] Among them, solution 1 is mainly used in fast charging type charging piles, and cannot solve the problem of tight charging load of slow charging type charging piles. Due to the high cost of firmware-based transformation of charging piles and routers, without good charging load monitoring support, the cost of charging load verification and charging anomaly investigation and positioning will increase; solution 2 is limited by external environmental factors such as power grid technology and electric vehicle technology, and is difficult to promote and apply; solution 3 is generally based on large-scale master control equipment to calculate and distribute current for charging through preset firmware programs. Although load balancing can be used to carry out orderly charging distribution at the time, because the current various types of vehicle models support non-standardized rated charging currents very differently, for charging users, charging expectations depend on the effectiveness of the master control equipment. Uncontrollable expectations often cause the actual charging situation of later users to be far from expectations during peak hours, resulting in very low user experience or even travel difficulties. At the same time, the master control equipment has higher relative equipment costs and construction costs. Once a problem occurs, the maintenance cost is also high, which is not conducive to promoting the construction of orderly charging. In addition, because the relevant business logic is embedded in the master control equipment, it is limited by hardware conditions, the business flexibility is reduced, and the operation means are rigid and rigid, which is not conducive to optimizing user experience and improving user stickiness. Summary of the invention

[0008] In view of the shortcomings of the prior art mentioned above, the purpose of the present invention is to provide a business model control method based on orderly charging to solve a series of problems such as the inability to effectively meet the charging needs of a sufficient number of new energy vehicle owners under a certain site distribution capacity, low construction costs, uncontrollable user expectations, and low operating capacity.

[0009] The present invention provides a service mode control method based on orderly charging, the method comprising the following process:

[0010] Step 1: Confirm and generate a planned charging order through the user APP;

[0011] Step 1.1: Obtain the charging pile networking status information through the online charging page of the user APP. If the charging pile is connected to the network, go to step 1.2;

[0012] Step 1.2: Obtain charging pile inventory plan information and account balance information through the online charging page of the user APP;

[0013] Step 1.3: Select the next travel time and planned charging amount through the charging confirmation interface of the user APP;

[0014] Step 1.4: Check the status of the gun head through the charging details page of the user APP. If the gun head is in the connected state, go to step 1.5;

[0015] Step 1.5: Check the charging pile networking status, account balance information, and charging pile inventory plan information through the charging details page of the user APP. If the charging pile is connected to the network, the account balance is satisfied, and the charging pile inventory plan remains unchanged, a planned charging order is generated;

[0016] Step 2: Remotely start charging through the user's APP scheduled charging order;

[0017] Step 2.1: Send a remote charging start instruction to the business backend server through the charging start page of the user APP according to the start time point in the charging pile inventory plan information, and remotely start charging through the business backend server;

[0018] Step 2.2: Send a remote start charging instruction to the business backend server through the charging shutdown page of the user APP according to the end time point in the charging pile inventory plan, and remotely shut down the charging through the business backend server;

[0019] Step 2.3: Obtain charging order settlement information through the charging settlement page of the user APP and make payment based on the account balance.

[0020] In one embodiment of the present invention, before and after charging is started, the charging fault type information is queried in real time through the fault prompt page of the user APP.

[0021] In one embodiment of the present invention, the charging fault types are divided into unrecoverable faults, background automatic recovery faults, and user recovery faults.

[0022] In one embodiment of the present invention, the calculation process of the charging pile inventory planning information is as follows:

[0023] (1) Pre-set the time redundancy of the charging pile inventory plan;

[0024] (2) Pre-calculate the horizontal width and vertical width of the charging site inventory and generate an inventory list;

[0025] (3) Calculate the horizontal and vertical occupancy of the planned charging order inventory;

[0026] (4) According to the first-come-first-served forward sorting rule, the horizontal occupancy and vertical occupancy of the planned charging order inventory are placed in the inventory list.

[0027] In one embodiment of the present invention, the horizontal width of the inventory is calculated based on the remaining distribution capacity of the charging site, which is the number of planned charging orders that can be charged simultaneously; the vertical width is the inventory resource pool composed of the minimum time slice.

[0028] In one embodiment of the present invention, if a planned charging order is cancelled or a time slice ends, the planned charging order is cleared from the inventory list, and the inventory list is rearranged in order.

[0029] In one embodiment of the present invention, a time slice is composed of one minimum time slice or multiple minimum time slices.

[0030] As described above, the service mode control method based on orderly charging of the present invention has the following beneficial effects:

[0031] The present invention allows users to choose the next travel time and control the planned charging amount within a certain range, so that user expectations are managed and users are cultivated to have the habit of daily charging. In addition, the present invention allows as many users as possible to perform daily charging, improves the charging success rate, stabilizes the user's charging frequency, reduces the user's anxiety about power consumption, increases the operator's operating methods and actual income, reduces the construction cost of charging piles, and improves operating efficiency.

[0036] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0037] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0038] The present invention provides a service mode control method based on orderly charging, the method comprising the following process:

[0039] Step 1: Confirm and generate a planned charging order through the user APP;

[0040] See also Figure 1 , the specific process is as follows:

[0041] Step 1.1: Scan and identify the QR code of the charging pile through the user APP installed on the mobile terminal. If the mobile terminal is connected to the Internet, enter the online charging page, and access the business backend server through the user APP. Obtain the charging pile networking status information through the online charging page of the user APP. If the charging pile is connected to the Internet, go to step 1.2; if the mobile terminal is offline, enter the offline charging page, and start offline charging through the offline charging page of the user APP;

[0042] Step 1.2: Access the business backend server through the user APP, and obtain the charging pile inventory plan information and account balance information through the online charging page of the user APP;

[0043] Step 1.3: Enter the charging confirmation interface through the user APP, and select the next travel time and planned charging amount through the charging confirmation interface of the user APP;

[0044] Step 1.4: Access the business backend server through the user APP and enter the charging details page. Check the status of the gun head through the charging details page of the user APP. If the gun head is in the connected state, go to step 1.5; if the gun head is not connected, wait for connection;

[0045] Step 1.5: Access the business backend server through the user APP, and check the charging pile networking status, mobile terminal networking status, account balance information, and charging pile inventory plan information through the charging details page of the user APP. If the charging pile is connected to the Internet, the mobile terminal is connected to the Internet, the account balance is satisfied, and the charging pile inventory plan remains unchanged, a planned charging order is generated and waiting for charging to start;

[0046] Otherwise, corresponding business prompts will be given, that is, when the inventory plan of the charging pile changes, the prompt "The planned charging order information has changed, please reconfirm" will be given; when the charging pile is offline, the prompt "The charging pile network is abnormal and charging cannot be started" will be given; when the mobile terminal is offline, the prompt "The mobile terminal network is abnormal and charging cannot be started" will be given.

[0047] Step 2: Start the charging process through the user's APP's planned charging order;

[0048] See also Figure 2 , the specific process is as follows:

[0049] Step 2.1: Send a remote charging start instruction to the business backend server through the charging start page of the user APP according to the start time point in the charging pile inventory plan, and remotely start charging through the business backend server;

[0050] If charging cannot be started immediately, wait for charging to start; if charging can be started immediately, access the business background server through the user APP, obtain the charging pile networking status information and the head connection status through the charging start page of the user APP, if the charging pile is connected to the network and the gun head is connected, send the start charging instruction to the charging pile through the business background server, and start charging remotely; if the charging pile is offline, continue to determine whether the charging pile is in the time limit for recovery. If so, try to start charging remotely again, otherwise the planned charging order ends; if the gun head is not connected, give a business prompt (for example, the gun head connection is abnormal, please handle it within the time limit), and determine whether it is handled within the time limit. If not, give a business prompt (for example: the abnormality is not handled, the planned charging fails). If it is handled, try to start charging remotely again;

[0051] Step 2.2: Send a remote start charging instruction to the business backend server through the charging shutdown page of the user APP according to the end time point in the charging pile inventory plan, and remotely shut down the charging through the business backend server;

[0052] Step 2.3: Access the business backend server through the user APP, obtain the charging order settlement information through the charging settlement page of the user APP, and pay the account balance.

[0053] Specifically, during the charging process, the business backend server is accessed through the APP, and the current status information of the charging pile is obtained in real time through the charging monitoring page of the user APP, and the consistency of the inventory management plan information and the actual charging information is monitored to ensure charging safety.

[0054] Specifically, if a fault occurs before or after charging starts, the planned charging cannot be completed. Therefore, the cause of the fault is identified through the business background server, and the charging fault type information is queried in real time through the fault prompt page of the user APP. The fault is processed according to the fault type classification. Among them, the charging fault types are divided into unrecoverable faults, background automatic recovery faults, and user recovery faults.

[0055] Among them, the user can recover the fault within the time limit by completing the relevant operations according to the prompts on the fault prompt page of the user APP and restarting charging; unrecoverable faults can be reported by completing the fault problem on the fault prompt page of the user APP.

[0056] Specifically, the charging pile inventory calculation information is based on the situation that the remaining power distribution capacity of the charging site is fixed and there is only one charging pile with a rated power. The width of the outbound inventory pool of the charging site is calculated, and the next travel order is calculated as an inventory resource occupying a certain length of the inventory width. The inventory pool resources are allocated in a first-come, first-served, forward sorting manner. The calculation process of the charging pile inventory plan information is as follows:

[0057] (1) Pre-set the time redundancy of the charging pile inventory plan;

[0058] For the slow charging order of 1KW charging time, through the charging order data of 3.5KW charging piles throughout 2019, after statistics and normal distribution, the time spent for charging 1KW is as follows:

[0059] According to the calculation that a 3.5kw rated power charging pile can charge 3.5kw per hour, the actual time taken to charge 3.5kw is calculated as follows:

[0060] The charging rate for more than 99% of the charging capacity is about 4942 seconds for every 3.5kw;

[0061] The ratio of the actual time to the 3.5kw rated time of 3600 seconds (1 hour) is approximately 4942 / 3600 = 137.2%

[0062] Therefore, the present invention selects 137.1% as the time redundancy of the charging pile inventory plan;

[0063] (2) Pre-calculate the horizontal width and vertical width of the charging site inventory and generate an inventory list;

[0064] Taking safety load redundancy into consideration, 19,816 charging pile samples were counted at the historical median charging current of 3.5 kW, of which 48 exceeded 18 A. For safety reasons, such situations must be prohibited. Therefore, if the charging current of the charging pile exceeds 2 A, the charging of the charging pile will stop.

[0065] Assume that the maximum remaining distribution capacity of the charging site is X, the safe power of one charging head is S = 16A (3.5kw) + 2A (0.44kw) = 18A, and the number of planned charging orders that can be charged simultaneously is O = X / S rounded up. Based on this, the simultaneous charging behavior of the charging site, that is, the inventory width, is calculated.

[0066] If the minimum inventory segmentation time period is half an hour, the horizontal width, that is, the number of planned charging orders that can be charged simultaneously, and the vertical minimum segmentation time (half an hour) are calculated to form an inventory resource pool.

[0067] (3) Calculate the horizontal and vertical occupancy of the planned charging order inventory;

[0068] Users only need to enter the next travel time and planned charging amount, which will be processed by the business background server and automatically sorted forward on a first-come, first-served basis, which is transparent to users.

[0069] For inventory sorting: 1. According to the next travel time and the planned charging amount, calculate the inventory occupancy of a single planned charging order = planned charging amount / 3.5*1.372, where 99% time redundancy is selected;

[0070] (4) According to the first-come-first-served forward sorting rule, the horizontal occupancy and vertical occupancy of the planned charging order inventory are placed in the inventory list. If it is less than one slice, it will be calculated as one slice;

[0071] Specifically, if the next travel time point cannot match the inventory list, the user can be informed of the maximum amount of power available at the next travel time point or the earliest time required to charge according to the filled plan;

[0072] Specifically, if a planned charging order is cancelled or a time slice ends, the planned charging order is cleared from the inventory list, and the inventory list is rearranged in order.

[0073] See also Figure 3 , Figure 4 , if order No. 4 is cancelled, the inventory occupied by orders No. 5, No. 6, and No. 7 is cleared, and order No. 5 is put into the inventory list, then No. 6 is put into the inventory, and finally No. 7 is put into the inventory. Therefore, all subsequent orders are in the original inventory list, and there will be no orders that cannot be included after reordering.

[0074] In summary, the present invention allows users to select the next travel time point within a certain range and control the planned charging range, so that user expectations are managed and users are trained to have the habit of daily charging; moreover, the present invention allows as many users as possible to perform daily charging, improves the charging success rate, stabilizes the user's charging frequency, reduces the user's power anxiety, increases the operator's operating methods and actual income, reduces the construction cost of charging piles, and improves operating efficiency. Therefore, the present invention effectively overcomes the various shortcomings of the prior art and has a high industrial utilization value.

[0075] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
