Description

Technical Field

[0001] The present invention relates to the field of charging, and more particularly to a charging device startup control method. Background Art

[0002] It is well known in the industry that DC charging piles need to go through vehicle interface connection confirmation, charger self-check, charging readiness and other stages before starting energy transmission. The whole process usually takes about 30s to 60s or even longer. Figure 1 This is the charging pile startup flow chart of the prior art. The charging pile starts the charging startup process only after the user scans the code and receives the platform's permission instruction. The entire startup charging startup process takes T3=T1+T2; the waiting time after the user scans the code to confirm that the charging is successful is T4=T2. Therefore, in actual use, the user needs to wait for a while after scanning the code until it is confirmed that the DC charging pile starts transmitting energy before leaving. The entire process from plugging in the gun, scanning the code to pay, to starting to transmit energy may take up to 2 to 3 minutes, which is time-consuming, inefficient, and seriously affects the user experience. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a charging device startup control method in view of the above-mentioned defects of the prior art, which can effectively shorten the charging startup waiting time, improve the charging efficiency and enhance the user experience.

[0004] The technical solution adopted by the present invention to solve the technical problem is: constructing a charging device startup control method, comprising:

[0005] S1, immediately start the charging start process when it is detected that the charging gun is inserted into the charging vehicle;

[0006] S2, executing the charging start-up process and the charging permission instruction generation process in parallel, when the charging start-up process is performed before the charging preparation is completed and the charging permission instruction is received within a preset time, starting the energy transmission from the charging gun to the charging vehicle or executing the remaining charging start-up process;

[0007] The remaining charging startup processes are charging startup processes other than the executed charging startup processes in the charging startup processes, and the executed charging startup processes are charging startup processes that have been executed before the charging permission instruction is received.

[0008] In the charging equipment startup control method described in the present invention, in the step S2, the charging startup process and the charging permission instruction generation process are executed in parallel; when the charging startup process proceeds to the end of the charging preparation and the charging permission instruction is received within the preset time, the energy transmission from the charging gun to the charging vehicle is started or the remaining charging startup process is executed; when the charging permission instruction has not been received before the end of the charging preparation, the set time is paused, and after the pause, the energy transmission from the charging gun to the charging vehicle is started, or the charging startup process is continued to be executed sequentially or the charging startup process is stopped.

[0009] In the charging device startup control method described in the present invention, the charging readiness includes pre-charging completion and command reception object messages in sequence; the charging permission instruction is an instruction generated after the user successfully interacts with the charging device.

[0010] In the charging device startup control method of the present invention, step S2 further includes:

[0011] S21, determining whether the charging start process receives the charging permission instruction before the pre-charging is completed, if yes, executing step S23, otherwise executing step S22;

[0012] S22, sending a pause message to the charging vehicle to set a first pause waiting time, and determining whether the charging permission instruction is received within the first pause waiting time, if yes, executing step S23, otherwise stopping the charging start process;

[0013] S23: Continue to execute the charging start process until the command receiving object message is completed and then immediately start the energy transmission from the charging gun to the charging vehicle.

[0014] In the charging device startup control method of the present invention, the step S2 further includes:

[0015] S2a, determining whether the charging start process has received the charging permission instruction before the command receiving object message ends, if yes, executing step S2c, otherwise executing step S2b;

[0016] S2b, setting a second pause waiting time for the charging vehicle to send a command receiving object message, and determining whether the charging permission instruction is received within the second pause waiting time, if yes, executing step S2c, otherwise stopping the charging start process;

[0017] S2c: Immediately start the energy transmission from the charging gun to the charging vehicle after the command receiving object message is completed.

[0018] In the charging device startup control method of the present invention, the step S2 further includes:

[0019] S2A, determining whether the charging start process receives the charging permission instruction before the pre-charging is completed, if yes, executing step S2C, otherwise executing step S2B;

[0020] S2B, sending a pause message to the charging vehicle to set a first pause waiting time, and determining whether the charging permission instruction is received within the first pause waiting time, if yes, executing step S2C, otherwise executing S2D;

[0021] S2C, continue to execute the charging start process until the command receiving object message ends and then immediately start the energy transmission from the charging gun to the charging vehicle;

[0022] S2D, determining whether the charging start process has received the charging permission instruction before the command receiving object message ends, if yes, executing step S2F, otherwise executing step S2E;

[0023] S2E, setting a second pause waiting time for the charging vehicle to send a command receiving object message, and determining whether the charging permission instruction is received within the second pause waiting time, if yes, executing step S2F, otherwise stopping the charging start process;

[0024] S2F: Immediately start the energy transmission from the charging gun to the charging vehicle after the command receiving object message is completed.

[0025] In the charging device startup control method of the present invention, in step S1, step S2 is immediately executed when the charging startup process is successfully started, and the user is immediately prompted to retry or replace the charging device when it fails.

[0026] In the charging device startup control method described in the present invention, in step S2, when the charging startup process reaches the end of the charging preparation and the charging permission instruction has not been received within the preset time, the charging startup process is stopped, and at the same time as the charging startup process is stopped, the user is prompted to scan the code for timeout or reinsert the charging gun.

[0027] In the charging equipment startup control method described in the present invention, in the step S1, when it is detected that the charging gun is inserted into the charging vehicle, the first display interface is displayed and maintained; and / or in the step S2, when the charging permission instruction is received, the charging display interface is displayed according to the charging process.

[0028] In the charging device startup control method described in the present invention, the first display interface includes a touch area, and the touch area is used to receive an unlocking instruction or a stop charging instruction from a user; the charging gun is unlocked based on the unlocking instruction, and the charging device stops the charging process based on the stop charging instruction.

[0029] Another technical solution adopted by the present invention to solve its technical problem is to construct a computer-readable storage medium, on which a computer program is stored. The computer program can be executed by a processor to implement any of the methods described above.

[0030] By implementing the charging equipment startup control method of the present invention, the charging startup process can be started immediately when it is detected that the charging gun is inserted into the charging vehicle, and the charging startup process and the charging instruction generation process are executed in parallel. Therefore, the charging startup process can be completed using the time of the charging instruction generation process, which can effectively shorten the charging startup waiting time and greatly shorten the user waiting time. It can not only effectively improve the charging efficiency, but also greatly improve the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0038] Figure 2 FIG. 1 is a flow chart of a preferred embodiment of the charging device startup control method of the present invention. Figure 2 As shown, the charging device startup control method of the present invention includes the following steps. In step S1, the charging startup process is immediately started when the charging gun is detected to be inserted into the charging vehicle. It is known to those skilled in the art that the charging startup process includes communication handshake, charger self-check and the charging readiness in sequence, and the charging readiness includes pre-charging completion and CRO (Command Receive Object, command receiving object) message in sequence. In a preferred embodiment of the present invention, step S2 is immediately executed when the charging startup process is successfully started, and the user is immediately prompted to retry or replace the charging device when it fails. That is, in this preferred embodiment, as long as the charging gun is inserted into the charging vehicle, it will not wait for the user to scan the code as in the prior art, and the charging startup process will be directly started. Under normal circumstances, the charging startup process is successfully started, and the user can use the execution time of this charging startup process to complete the scanning operation. If the startup fails, there is no need to wait for the user to scan the code result, and the failure can be directly fed back, for example, the user can be immediately prompted to retry or replace the charging device. In a preferred embodiment of the present invention, the charging device is a charging pile. Of course, in a further preferred embodiment of the present invention, the charging device can also include any other similar charging devices, which all fall within the scope of protection of the present invention.

[0039] In step S2, the charging start-up process and the charging instruction generation process are executed in parallel. When the charging start-up process is performed before the charging preparation is completed and the charging instruction is received within the preset time, the energy transmission from the charging gun to the charging vehicle is started or the remaining charging start-up process is executed. Among them, the remaining charging start-up process is the charging start-up process other than the executed charging start-up process in the charging start-up process, and the executed charging start-up process is the charging start-up process that has been executed before the charging instruction is received. In a preferred embodiment of the present invention, after the charging start-up process is started, the charging device, such as the charging pile, automatically communicates handshake, charger self-check, pre-charge completion and CRO message in sequence, and executes the charging instruction generation process in parallel while executing the charging start-up process. Since the charging start-up process and the charging instruction generation process are executed in parallel, the user can use the execution time of this charging start-up process to complete the charging instruction generation process. In the present invention, the charging instruction is an instruction generated after the user successfully interacts with the charging device. The charging instruction generation process refers to the entire process of successfully completing the interaction between the user and the charging device and generating the charging instruction. The user's successful interaction with the charging device may be the user's successful scanning of the code, successful input of the URL, successful login of the mini program, or any other process that requires the user to perform an operation and confirmation by the charging device to generate a charging permission instruction.

[0040] For the convenience of description, we will explain the charging pile with the most familiar scanning code operation. Preferably, the charging permission instruction is generated after the user successfully scans the charging QR code. If the user successfully scans the code before the charging startup process is completed and the charging is ready, the charging pile will receive the charging permission instruction. After the charging pile receives the charging permission instruction, the energy transmission from the charging gun to the charging vehicle can be started, that is, charging is performed normally. If the user successfully scans the code before the charging startup process is completed and the charger self-check is completed, the charging pile will receive the charging permission instruction. After the charging pile receives the charging permission instruction, the remaining charging readiness process will continue to be executed, and then after the charging readiness process is completed, the energy transmission from the charging gun to the charging vehicle will be started. If the user fails to scan the code successfully before the charging is ready, normal charging will not continue. Here, successful code scanning can be that the user successfully scans the code and successfully pays, or that the user successfully scans the code and normally signs a prepaid contract, etc. Here, the actual meaning of successful code scanning can be determined according to the specific agreement between the charging station and the charging vehicle, which all fall within the scope of protection of the present invention. The charging QR code can be an electronic QR code, which is displayed on a display screen on the charging pile, or a paper QR code, which can be set at any suitable location, such as a charging pile.

[0041] By implementing the charging equipment startup control method of the present invention, the charging startup process can be started immediately when it is detected that the charging gun is inserted into the charging vehicle, and the charging startup process and the charging instruction generation process are executed in parallel. Therefore, the charging startup process can be completed using the time of the charging instruction generation process, which can effectively shorten the charging startup waiting time and greatly shorten the user waiting time. It can not only effectively improve the charging efficiency, but also greatly improve the user experience.

[0042] Figure 3 is based on Figure 2 The charging pile startup process diagram of the charging equipment startup control method shown in FIG. Figure 3 The time required for the charging device startup control method of the present invention is described as follows. Figure 3 As shown, if the startup failure is found, the time T6 = T5, the user is directly prompted with the fault information, which has nothing to do with scanning the code. Figure 1 The startup failure time required by the startup process of the prior art shown in the figure is T6 = T1 + T5, which saves time T1. If the time T2 for the user to scan the code is greater than the time T1 for the charging startup process, then the entire charging startup process takes T3 = T2, which is equivalent to Figure 1Compared with the prior art T3=T1+T2 shown in the figure, the waiting time after scanning the code is only related to the response time of the charging pile, that is, T4 is about 1~2s, which can be almost ignored. If the time taken by the user to scan the code T2 is less than the time taken by the charger to start the process T1, then the entire charging start process takes T3=T1, which is equivalent to Figure 1 The prior art T3 = T1 + T2 shows that the time saved is T2, and the waiting time after the user scans the code is T4 = T1 - T2. Therefore, compared with the prior art, no matter what the situation, the technical solution of the present invention is adopted, the time consumed by the entire startup charging process is much shorter than the time consumed by the entire startup charging process in the prior art, and the waiting time after the user scans the code is also much shorter than the waiting time after the user scans the code in the prior art.

[0043] In the present invention, the charging startup process is immediately started when it is detected that the charging gun is inserted into the charging vehicle, and the various stages of the charging startup process (i.e., communication handshake, self-check, and charging preparation) are executed by using the time when the user scans the code to pay. Before the energy transmission incurs fees, it is determined whether the platform has sent an instruction to allow charging. If so, the energy transmission is started directly. If not, the charging process is stopped when the instruction is given or the timeout occurs and the gun is reinserted to speed up the progress of the charging process.

[0044] Therefore, by adopting the technical solution of the present invention, the startup result can be immediately fed back when the charging gun is detected to be inserted into the charging vehicle, without having to wait for the code scanning result, which greatly shortens the startup time when the startup fails. At the same time, the charging startup process is immediately started when the startup is successful, and the charging startup process is completed using the user's code scanning time. It can effectively shorten the charging pile startup waiting time and greatly shorten the waiting time after the user scans the code, which can not only effectively improve the charging efficiency, but also greatly improve the user experience.

[0045] Those skilled in the art know that the charging start process includes communication handshake, charger self-check and charging readiness in sequence, and the charging readiness includes pre-charging completion and CRO message in sequence. For users with poor network or unskilled users, it is possible that the code scanning operation cannot be completed before the charging start process reaches the end of charging readiness. If it is directly determined that the charging permission instruction has not been received and the charging start process is stopped, it may cause multiple stops, which will cause the charging start process to be too long and the user experience to be poor.

[0046] In view of this situation, the applicant further proposed an improvement plan as follows, that is, in the pre-charge completion and CRO messages of charging readiness, a certain pause delay is designed to wait for the charging permission instruction. That is, in a preferred embodiment of the present invention, in step S2, the charging start process and the charging permission instruction generation process are executed in parallel; when the charging start process is performed before the end of charging readiness and the charging permission instruction is received within the preset time, the energy transmission from the charging gun to the charging vehicle is started or the remaining charging start process is executed; when the charging permission instruction has not been received before the end of the charging readiness, the setting time is paused, and after the pause, the energy transmission from the charging gun to the charging vehicle is started, or the charging start process is continued to be executed sequentially or the charging start process is stopped. In this preferred embodiment, we can provide users with a better experience by pausing the setting time to prevent multiple stops due to poor network signals or unskilled operation. As mentioned above, the charging readiness includes pre-charge completion and command reception object messages in sequence. Therefore, the pause setting time can occur once, and only occurs when the pre-charging is completed or the command is received. It can also occur twice, that is, the pre-charging is completed and the command is received. The object message is paused respectively. They will be explained separately later. In a preferred embodiment of the present invention, we provide more time for the user to scan by suspending the pre-charging completion of the charging startup process. The specific implementation method is as follows. As mentioned above, in step S1, the charging startup process is immediately started when it is detected that the charging gun is inserted into the charging vehicle. If the startup fails, the startup result is immediately fed back. For example, the user can be immediately prompted to retry or replace the charging pile. If the startup is normal, then execute step S21, immediately execute the charging startup process normally in sequence, and determine whether the charging permission instruction is received before the charging startup process reaches the end of the pre-charging completion. If so, execute step S23, otherwise execute step S22.

[0047] In step S22, since the charging permission instruction is not received, a pause message is sent to the charging vehicle to set a first pause waiting time, and it is determined whether the charging permission instruction is received within the first pause waiting time. If so, step S23 is executed, otherwise the charging start process is stopped. In step S23, the charging start process is continued until the energy transmission from the charging gun to the charging vehicle is immediately started after the CRO message ends. In this application, immediate start can include the reaction error time of the system, such as 1 to 2s. Of course, with system optimization, the reaction time may be further reduced.

[0048] In this preferred embodiment, if the time taken by the user to scan the code T2 is less than the time required for the charger startup process to complete pre-charging, then the charging pile will receive the charging permission instruction before the pre-charging is completed, and the charging pile will continue to execute the charging startup process until the CRO message ends and immediately starts the energy transmission from the charging gun to the charging vehicle. If the time taken by the user to scan the code T2 is greater than the time required for the charger startup process to complete pre-charging, we will set a certain delay to extend the waiting time for the charging permission instruction, so as to avoid interruption of the charging startup process. However, in order to avoid the problem that the charging pile does not receive instructions for a long time, thereby affecting efficiency, after the set waiting time expires, the charging startup process will be stopped and the charging pile will be released to avoid the charging pile being occupied ineffectively for a long time.

[0049] The following is explained with a specific example. Before the charging start-up process reaches the end of the pre-charging completion, the charging controller receives the charging permission instruction sent by the platform, and then continues to execute the charging start-up process until the CRO message ends, and then immediately starts the energy transmission from the charging gun to the charging vehicle. Before the charging start-up process reaches the end of the pre-charging completion, the charging controller does not receive the charging permission instruction sent by the platform, then the charging controller can control the charging module output current to zero and send the "Pause" message in the "PGN4608 charger status message" to the charging vehicle. The PGN4608 message format is shown in the following table (GB / T 27930-2023 Digital Communication Protocol between Non-Onboard Conductive Chargers and Electric Vehicles 11.3.3).

[0050] Start byte or bit length SPN SPN Definition Sending Options 1 2 bytes 3081 Current voltage measurement value of vehicle interface / V Required 3 2 bytes 3082 Current measurement value of vehicle interface / A Required 5 2 bytes 3083 Cumulative charging time / min Required 7.1 2-digit 3929 Charging allowed (<00>: = pause; <01> ; = Allow) Required

[0051] At this time, the first pause waiting time Tdelay can be set as follows: 2 , and make the following judgment. Under normal circumstances, charging stations, especially charging stations in high-speed service areas, will not allow charging piles to be occupied for a long time. The first pause waiting time Tdelay 2 It cannot be set too long. Considering that the normal operation of scanning the QR code with a mobile phone to start charging takes about 1 to 2 minutes, Tdelay 2 Usually set to 1 to 2 minutes. 2 If the charging controller receives the platform's permission to charge instruction, it continues the normal charging process, that is, continues to execute the charging start process until the CRO message ends and immediately starts the energy transmission from the charging gun to the charging vehicle. 2 , the charging controller did not receive the platform's instruction to allow charging, so the charging controller terminated charging and prompted the user to re-insert the gun because the code scanning timed out.

[0052] Of course, in other preferred embodiments of the present invention, other values ​​of the first pause waiting time may be set according to actual conditions, such as Tdelay. 2 <10min, other messages can also be used to set the first pause waiting time Tdelay 2 , all of which fall within the protection scope of the present invention.

[0053] In order to better illustrate the beneficial effects of the present invention, the present invention uses the aforementioned charging equipment startup control method of the present invention and the prior art to start the charging pile based on the same preset time, and the process and results are as follows: Figure 4-5 As shown. Figure 4 As shown in the figure, it is assumed that a DC charger at a charging station in a high-speed service area takes 40 seconds from startup to current output, and the above-mentioned 50-second delay for pre-charging is adopted. After the owner of the charging vehicle plugs in the gun, it takes 45 seconds to take out the mobile phone, unlock, scan the code, enter the amount, enter the password, and click to start charging. It is observed that the charging interface has switched from the plugged-in state interface to the pre-charging stage interface, and waits for 1 to 2 seconds. s That is, the charging interface is entered, the charging current starts to output, and the owner confirms that the charging is successful and leaves to do other activities. The charging device startup control method of the present invention takes 47 seconds, and the user waits for 2 seconds to confirm the successful charging. Figure 5 As shown, the normal charging process takes 85 seconds, and the waiting time for confirmation of successful charging is 40 seconds.

[0054] In another preferred embodiment of the present invention, we provide more time for the user to scan by pausing the CRO message of the charging start process, and the specific implementation method is as follows.

[0055] As mentioned above, in step S1, the charging start-up process is immediately started when the charging gun is detected to be inserted into the charging vehicle. If the start-up fails, the start-up result is immediately fed back. For example, the user can be immediately prompted to retry or replace the charging pile. If the start-up is normal, then step S2a is executed, and the charging start-up process is immediately and normally executed in sequence to determine whether the charging start-up process receives the charging permission instruction before the CRO message ends. If so, step S2c is executed, otherwise step S2b is executed.

[0056] In step S2b, a second pause waiting time is set for the charging vehicle to send the CRO message, and it is determined whether the charging permission instruction is received within the second pause waiting time. If yes, step S2c is executed, otherwise the charging start process is stopped. In step S2c, the energy transmission from the charging gun to the charging vehicle is started immediately after the CRO message ends.

[0057] In this preferred embodiment, if the time taken by the user to scan the code T2 is less than the time required for the charger startup process to proceed to the CRO message, then after the charging pile receives the instruction to allow charging, it directly executes the CRO message according to the normal charging startup process and starts the energy transmission from the charging gun to the charging vehicle. If the time taken by the user to scan the code T2 is greater than the time required for the charger startup process to proceed to the CRO message, we will set a certain delay to extend the waiting time for the instruction to allow charging, so as to avoid interruption of the charging startup process. However, in order to avoid the problem that the charging pile does not receive the instruction for a long time, thereby affecting the efficiency, after the set waiting time expires, the charging startup process will be stopped and the charging pile will be released to avoid the charging pile being occupied ineffectively for a long time.

[0058] The following is explained with a specific example. Before the charging start process reaches the end of the CRO message, the charging controller receives the charging permission instruction sent by the platform, and immediately starts the energy transmission from the charging gun to the charging vehicle after the CRO message ends. After the charging controller receives the "PGN vehicle charging ready message (BRO)" signal, the DC charger needs to send the "PGN2560 charger output ready message (CRO)" (according to B / T 27930-2023 Digital Communication Protocol between Non-Onboard Conductive Chargers and Electric Vehicles Article 11.2.5)). The PGN2560 message format is shown in the following table.

[0059]

[0060] At this time, the charging master controller can set a second pause waiting time for sending the CRO message to the charging vehicle, that is, the charging master controller waits for the second pause waiting time before sending the CRO message to the charging vehicle. At this time, the second pause waiting time T can be set as follows delay1 And make the following determination. Preferably, the second pause waiting time T delay1 <60s. If the second pause waiting time T delay1 If the charging controller receives the charging permission instruction, it will continue the normal charging process, that is, continue to execute the charging start process until the CRO message ends and immediately start the energy transmission from the charging gun to the charging vehicle. delay1 If the charging controller does not receive the charging permission command from the platform, the charging controller will terminate the charging and prompt the user that the code scanning timeout has occurred and the gun needs to be re-inserted.

[0061] Of course, in other preferred embodiments of the present invention, other values ​​of the second pause waiting time may be set according to actual conditions, which all fall within the protection scope of the present invention.

[0062] In a further preferred embodiment of the present invention, we provide more time for user scanning by pausing twice, namely pausing the pre-charge completion and CRO message of the charging start process, and the specific implementation method is as follows.

[0063] As mentioned above, in step S1, the charging start-up process is immediately started when the charging gun is detected to be inserted into the charging vehicle. If the start-up fails, the start-up result is immediately fed back. For example, the user can be immediately prompted to retry or replace the charging pile. If the start-up is normal, then step S2A is executed, and the charging start-up process is immediately executed normally in sequence, and it is determined whether the charging permission instruction is received before the charging start-up process is completed. If so, step S2C is executed, otherwise step S2B is executed.

[0064] In step S2B, since the charging permission instruction is not received, a pause message is sent to the charging vehicle to set a first pause waiting time, and it is determined whether the charging permission instruction is received within the first pause waiting time. If yes, step S2C is executed, otherwise S2D is executed. In step S2C, the charging start-up process is continued until the energy transmission from the charging gun to the charging vehicle is immediately started after the CRO message ends. In step S2D, it is determined whether the charging permission instruction is received before the charging start-up process ends until the CRO message ends. If yes, step S2F is executed, otherwise step S2E is executed.

[0065] In step S2E, a second pause waiting time is set for the charging vehicle to send the CRO message, and it is determined whether the charging permission instruction is received within the second pause waiting time. If yes, step S2F is executed, otherwise the charging start process is stopped. In step S2F, the energy transmission from the charging gun to the charging vehicle is started immediately after the CRO message ends.

[0066] In this preferred embodiment, the specific implementation of the two pauses can refer to the previous two embodiments, which will not be repeated here.

[0067] In a further preferred embodiment of the present invention, in order to avoid the user misunderstanding that the charging machine starts charging without scanning the payment code, in the step S1, when it is detected that the charging gun is inserted into the charging vehicle, the first display interface is displayed and maintained. Preferably, when it is detected that the charging gun is inserted into the charging vehicle, the display is as follows: Figure 6The first display interface is shown. The first display interface preferably includes a touch area, and the touch area is used to receive an unlocking instruction or a stop charging instruction from the user. The charging gun can be unlocked based on the unlocking instruction, and the charging pile stops the entire charging process based on the stop charging instruction. This can cope with individual situations where the user needs to plug in the gun but does not need to charge and needs to leave, and can meet the special requirements of the user. If the instruction to allow charging is not received, the first display interface will remain, which can prevent the user from mistakenly thinking that charging has started. When the instruction to allow charging is received, the charging display interface is displayed according to the charging process to inform the user that the charging process has officially started.
