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] As is well known in the industry, a DC charging pile needs to go through stages such as vehicle interface connection confirmation, charger self-test, and charging readiness before starting energy transmission. The entire process usually takes about 30s to 60s or even longer. Figure 1 This is a flowchart of the charging pile startup process in the existing technology. The charging pile will not start the charging startup process until the user scans the code and receives the platform's permission instruction. The entire charging startup process takes time 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, after scanning the code, the user needs to wait for a while until the DC charging pile is confirmed to have started transmitting energy before leaving. The entire process from plugging in the gun, scanning the code to pay, and starting energy transmission can 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 to address the above-mentioned defects of the prior art, which can effectively shorten the charging startup waiting time, improve charging efficiency and enhance user experience.

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

[0005] S1. Immediately start the charging start process when detecting that the charging gun is inserted into the charging vehicle;

[0006] S2. Executing the charging startup process and the charging permission instruction generation process in parallel. When the charging startup process reaches the end of the charging preparation 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 startup 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 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 is over, 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-up 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 so, executing step S23, otherwise stopping the charging start process;

[0013] S23: Continue to execute the charging start-up 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, step S2 further includes:

[0015] S2a, determining whether the charging permission instruction is received before the charging start process reaches the end of the command reception object message, 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 so, executing step S2c, otherwise stopping the charging start process;

[0017] S2c: Immediately start 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, step S2 further includes:

[0019] S2A, determining whether the charging permission instruction is received before the pre-charging is completed during the charging start-up process; if so, 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 so, executing step S2C, otherwise executing step S2D;

[0021] S2C: Continue executing the charging start-up process until the command receiving object message is completed and immediately start the energy transmission from the charging gun to the charging vehicle;

[0022] S2D, determining whether the charging permission instruction is received before the charging start process reaches the end of the command reception object message, 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 so, 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 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 stopping the charging startup process, 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 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 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 the user's unlocking instruction or stop charging instruction; 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 immediately started 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 solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to 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, upon detecting that a charging gun is plugged into a charging vehicle, the charging startup process is immediately initiated. Those skilled in the art will appreciate that the charging startup process sequentially includes a communication handshake, a charger self-test, and the charging readiness state, which in turn includes a pre-charge completion message and a CRO (Command Receive Object) message. In a preferred embodiment of the present invention, step S2 is immediately executed upon successful startup of the charging startup process. Upon failure, the user is immediately prompted to retry or replace the charging device. In other words, in this preferred embodiment, the charging startup process is initiated directly upon the charging gun being plugged into the charging vehicle, without waiting for the user to scan a code as in the prior art. Under normal circumstances, if the charging startup process is successful, the user can use the execution time of the charging startup process to complete the code scanning operation. If the startup fails, the failure is directly reported without waiting for the user to scan the code result; for example, the user may be 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 further preferred embodiments of the present invention, the charging device may also include any other similar charging device, all of which fall within the scope of protection of the present invention.

[0039] In step S2, the charging initiation process and the charge permission instruction generation process are executed in parallel. When the charging initiation process reaches the end of the charging preparation phase and the charge permission instruction is received within a preset time, energy transmission from the charging gun to the charging vehicle is initiated or the remaining charging initiation process is executed. The remaining charging initiation process refers to the charging initiation process in addition to the already executed charging initiation process, and the already executed charging initiation process refers to the charging initiation process that was executed before the charge permission instruction was received. In a preferred embodiment of the present invention, after the charging initiation process is initiated, the charging device, such as the charging pile, automatically and sequentially performs communication handshake, charger self-test, pre-charge completion, and CRO messages. While executing the charging initiation process, the charge permission instruction generation process is executed in parallel. Because the charging initiation process and the charge permission instruction generation process are executed in parallel, the user can use the execution time of the charging initiation process to complete the charge permission instruction generation process. In the present invention, the charge permission instruction is the instruction generated after the user successfully interacts with the charging device. The charge permission instruction generation process refers to the entire process from the successful interaction between the user and the charging device to the generation of the charge permission instruction. The user's successful interaction with the charging device can be a successful code scan, a successful URL input, a successful login to 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 ease of description, we will use the familiar scanning QR code operation for charging stations. Preferably, the "allow charging" instruction is generated after the user successfully scans the charging QR code. If the user successfully scans the code before the charging start-up process reaches the end of the charging preparation phase, the charging station will receive the "allow charging" instruction. After receiving the "allow charging" instruction, the charging station can initiate energy transfer from the charging gun to the charging vehicle, i.e., charging will proceed normally. If the user successfully scans the code before the charger self-test phase of the charging start-up process, the charging station will receive the "allow charging" instruction. After receiving the "allow charging" instruction, the charging station will continue the remaining charging preparation phase and then, after the charging preparation phase, initiate energy transfer from the charging gun to the charging vehicle. If the user fails to successfully scan the code before the charging preparation phase ends, normal charging will not proceed. A successful code scan can mean that the user successfully scans the code and pays the bill, or that the user successfully scans the code and signs a prepaid payment agreement, etc. The actual meaning of a successful code scan can be determined based on the specific agreement between the charging station and the charging vehicle, and all of these fall within the scope of protection of this 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 immediately started 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 taken is T6=T5, and 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 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 the time T1 for the charging startup process. Figure 1The T3=T1+T2 of the prior art shown saves time T1. At this time, 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 is almost negligible. If the time T2 for the user to scan the code is less than the time T1 for the charger startup process, then the entire charging startup process takes T3=T1, which is equivalent to the charging time. Figure 1 The prior art shows that T3 = T1 + T2, which saves time T2. The waiting time after the user scans the code is T4 = T1 - T2. Therefore, compared with the prior art, regardless of the situation, the technical solution of the present invention significantly reduces the time required for the entire startup charging process, and the waiting time after the user scans the code is also significantly reduced.

[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. The various stages of the charging startup process (i.e., communication handshake, self-test, 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, energy transmission is started directly. If not, wait for instructions or stop the charging process due to timeout and re-plug the gun 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 waiting time for the charging pile to start, 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 will appreciate that the charging startup process sequentially includes a communication handshake, a charger self-test, and the charging readiness phase, which in turn includes the pre-charge completion phase and a CRO message. For users with poor network connectivity or inexperienced users, the code scanning process may not be completed before the charging readiness phase is complete. If the charging startup process is terminated at this point, assuming the charging permission instruction has not been received, this may result in multiple interruptions, resulting in a prolonged charging startup process and a poor user experience.

[0046] In response to this situation, the applicant further proposed an improved solution as follows, namely, in the pre-charge completion and CRO messages of charging readiness, a certain pause delay is designed to wait for the permission to charge instruction. That is, in a preferred embodiment of the present invention, in step S2, the charging start process and the permission to charge instruction generation process are executed in parallel; when the charging start process reaches the end of charging readiness and the permission to charge instruction is received within a 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 permission to charge instruction has not been received before the end of charging readiness, the set time is paused, and after the pause is over, the energy transmission from the charging gun to the charging vehicle is started, or the sequential execution of the charging start process is continued or the charging start process is stopped. In this preferred embodiment, by pausing the set time, we can provide users with a better experience and 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-charge is completed or the command is received. It can also occur twice, that is, the pre-charge 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 pausing the pre-charge completion of the charging start-up process. The specific implementation method is as follows. As mentioned above, in step S1, the charging start-up 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 prompted to retry or replace the charging pile immediately. If the startup is normal, then step S21 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 reaches the end of the pre-charge completion. If so, step S23 is executed, otherwise step S22 is executed.

[0047] In step S22, since the charging permission instruction was not received, a pause message is sent to the charging vehicle to set a first pause waiting time. The process then determines whether the charging permission instruction is received within the first pause waiting time. If so, step S23 is executed; otherwise, the charging start-up process is terminated. In step S23, the charging start-up process continues until the CRO message ends, at which point energy transmission from the charging gun to the charging vehicle is immediately initiated. In this application, immediate start-up can include the system's reaction error time, such as 1 to 2 seconds. Of course, this reaction time may be further reduced as the system is optimized.

[0048] In this preferred embodiment, if the time T2 taken by the user to scan the code is less than the time required for the charger startup process to complete pre-charging, then the charging pile will receive the permission to charge 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 T2 taken by the user to scan the code 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 permission to charge 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, the charging startup process will be stopped after the set waiting time expires, and the charging pile will be released to prevent the charging pile from 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, the charging controller receives a charging permission instruction sent by the platform, and then continues to execute the charging start-up process until the CRO message ends and 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, the charging controller does not receive a charging permission instruction sent by the platform, then the charging controller can control the output current of the charging module to zero and send a "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, Article 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 people 3929 Charging allowed (<00>: = pause; <01> ; = allow) Required

[0051] At this time, the following first pause waiting time Tdelay2 can be set, and the following judgment can be made. Under normal circumstances, operating 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 Tdelay2 cannot be set too long. Considering that the time it takes for ordinary people to scan the code with their mobile phones to start charging is about 1 to 2 minutes, Tdelay2 is usually set to 1 to 2 minutes. Within the first pause waiting time Tdelay2, if the charging controller receives a charging permission instruction from the platform, the normal charging process will continue, that is, the charging start process will continue to be executed until the CRO message ends and the energy transmission from the charging gun to the charging vehicle will be started immediately. If the first pause waiting time Tdelay2 is exceeded, the charging controller has not received the charging permission instruction from the platform, the charging controller will suspend charging and prompt the user that the code scanning timeout requires re-insertion of the gun.

[0052] Of course, in other preferred embodiments of the present invention, the first pause waiting time can be set to other values ​​according to actual conditions, such as Tdelay2<10min, or other messages can be used to set the first pause waiting time Tdelay2, all of which fall within the scope of protection 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. 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 highway service area takes 40 seconds from startup to current output. The above-mentioned 50-second delay scheme for pre-charging is adopted. After the owner of the charging vehicle plugs in the gun, it takes 45 seconds to take out the phone, unlock, scan the code, enter the amount, enter the password, and click to start charging. 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 above-mentioned charging device startup control method of the present invention takes 47 seconds, and the user waits for confirmation of successful charging for 2 seconds. Using the charging startup method of the prior art, such as 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. The specific implementation method is as follows.

[0055] As previously described, in step S1, the charging startup process is immediately initiated upon detecting that the charging gun is plugged into the charging vehicle. If the startup fails, the startup result is immediately fed back. For example, the user may be prompted to retry or change the charging station. If the startup is successful, step S2a is executed, and the charging startup process is immediately and normally executed. It is determined whether the charging permission instruction is received before the end of the charging startup process and the CRO message. If so, step S2c is executed; otherwise, step S2b is executed.

[0056] In step S2b, a second pause wait time is set for the charging vehicle to send a CRO message, and a determination is made as to whether the charging permission instruction is received within the second pause wait time. If so, step S2c is executed; otherwise, the charging initiation process is terminated. In step S2c, energy transmission from the charging gun to the charging vehicle is immediately initiated after the CRO message ends.

[0057] In this preferred embodiment, if the time T2 required for the user to scan the QR code is less than the time required for the charger startup process to reach the CRO message, then after the charging station receives the "allow charging" instruction, it directly executes the CRO message according to the normal charging startup process and initiates energy transmission from the charging gun to the charging vehicle. If the time T2 required for the user to scan the QR code is greater than the time required for the charger startup process to reach the CRO message, a delay is set to extend the waiting time for the "allow charging" instruction, thereby avoiding interruptions in the charging startup process. However, to prevent the charging station from not receiving instructions for a long time, thereby affecting efficiency, the charging startup process is terminated after the set waiting time expires, releasing the charging station to prevent the charging station from being unused for a long time.

[0058] The following is an explanation 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 Off-Board Conductive Chargers and Electric Vehicles 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 judgment. 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 platform's instruction to allow charging, the charging controller will stop 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, the second pause waiting time may be set to other values ​​according to actual conditions, and all of these 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. The specific implementation method is as follows.

[0063] As previously described, in step S1, the charging startup process is immediately initiated upon detecting that the charging gun is plugged into the charging vehicle. If the startup fails, the startup result is immediately fed back. For example, the user may be prompted to retry or replace the charging station. If the startup is normal, step S2A is executed, and the charging startup process is immediately executed normally. It is determined whether the charging permission instruction is received before the pre-charging is completed. If so, step S2C is executed; otherwise, step S2B is executed.

[0064] In step S2B, since the charging permission instruction was not received, a pause message is sent to the charging vehicle to set a first pause waiting time. A determination is made as to whether the charging permission instruction was received within the first pause waiting time. If so, step S2C is executed; otherwise, step S2D is executed. In step S2C, the charging startup process continues until the CRO message ends, at which point energy transmission from the charging gun to the charging vehicle is immediately initiated. In step S2D, a determination is made as to whether the charging permission instruction was received before the CRO message ends. If so, step S2F is executed; otherwise, step S2E is executed.

[0065] In step S2E, a second pause wait time is set for the charging vehicle to send a CRO message, and a determination is made as to whether the charging permission instruction is received within the second pause wait time. If so, step S2F is executed; otherwise, the charging initiation process is terminated. In step S2F, energy transmission from the charging gun to the charging vehicle is immediately initiated after the CRO message ends.

[0066] In this preferred embodiment, the specific implementation of the two pauses can refer to the previous two embodiments and 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 the charging gun is detected to be inserted into the charging vehicle, the first display interface is displayed and maintained. Preferably, when the charging gun is detected to be inserted into the charging vehicle, the following display interface is displayed: Figure 6The first display interface is shown. The first display interface preferably includes a touch area, and the touch area is used to receive the user's unlocking instruction or the stop charging instruction. 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 user's special requirements. If the instruction to allow charging is not received, the first display interface will remain, so as to avoid the user 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.

[0068] Those skilled in the art will appreciate that all or part of the functions of the various methods in the above embodiments can be implemented by hardware or by computer program. When all or part of the functions in the above embodiments are implemented by computer program, the program can be stored in a computer-readable storage medium, and the storage medium can include: read-only memory, random access memory, disk, optical disk, hard disk, etc., and the program is executed by a computer to implement the above functions. For example, the program is stored in the memory of the device, and when the program in the memory is executed by the processor, all or part of the above functions can be implemented.
