[0003] At present, unmanned public charging stations are developing rapidly. However, many vehicles currently have poor compatibility between vehicles and charging piles during the charging process, which leads to the inability to complete charging.

[0004] When a vehicle is incompatible with the charging pile, the vehicle will be driven away from the charging station and the relevant data cannot be fed back to the charging station's backend processing system, making it impossible to conduct in-depth analysis of the reasons for the failure to charge, and it will be difficult to improve the compatibility of the charging equipment.

[0005] In addition, the layout of charging equipment is scattered, and when a failure occurs, engineers are required to provide on-site technical support, which will cause a lot of manpower waste and reduce the timeliness of problem solving.

[0006] In the prior art, there are related detection devices. The current detection devices simulate the BMS protocol and are fixed and single, and cannot perform intelligent switching of multiple versions of protocols, which is somewhat one-sided. In addition, the existing detection devices cannot fundamentally solve the charging equipment version upgrade and compatibility improvement, and cannot realize remote intelligent operation and maintenance. Summary of the invention

[0007] In order to overcome the above-mentioned deficiencies of the prior art, the present invention provides a full-closed-loop detection system for intelligent operation and maintenance of charging equipment, which can improve the intelligent operation and maintenance capabilities and compatibility level of the charging equipment.

[0023] In the second aspect, a fully closed-loop detection method for intelligent operation and maintenance of charging equipment is disclosed, comprising:

[0024] When the vehicle charging stops abnormally, a simulated BMS protocol is generated based on the BMS interaction information, and the charging monitoring LOG is actively downloaded;

[0025] The LOG log and BMS protocol are stored separately, and then the data is extracted to simulate and review the charging process, analyze it in multiple dimensions, determine the cause of abnormal shutdown, and classify the shutdown reasons;

[0043] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0044] It should be noted that the terms used herein are for describing specific embodiments only and are not intended to be limiting of exemplary embodiments according to the present invention.

[0045] In the absence of conflict, the embodiments of the present invention and the features of the embodiments may be combined with each other.

[0046] Embodiment 1

[0047] like Figure 1 As shown, this embodiment discloses a fully closed-loop detection system for intelligent operation and maintenance of charging equipment, including: an intelligent terminal module, a smart operation and maintenance platform and an intelligent detection device.

[0048] The intelligent terminal module is a module placed inside a conventional charging pile terminal. The intelligent terminal module is connected to the charging monitoring module and uses NET / CAN communication to transmit charging logs and control the remote upgrade process of charging monitoring.

[0049] The intelligent terminal module is connected to the intelligent operation and maintenance platform, using 4G / NET communication to upload charging LOGs and BMS protocols, and transmit charging monitoring remote upgrade programs.

[0050] The intelligent terminal module is mounted on the CAN line of the BMS. CAN communication can be used to record BMS information interaction during charging, and BMS protocols can be generated when charging is abnormally shut down. The intelligent terminal module can also realize local storage of SD cards and remote restart of charging equipment.

[0051] In this implementation example, see the attached Figure 2 As shown, the intelligent terminal module contains active input and output, and the active input and output control the monitoring power relay. The monitoring power relay includes a coil, a normally open contact and a normally closed contact. The normally closed contact is connected to the monitoring power supply, the normally open contact is connected to the input of the intelligent terminal module, and the coil is connected to the output of the intelligent terminal module; wherein the relay normally closed contact controls the on-off of the monitoring power supply line, and the normally open contact is used for relay status feedback. In this way, the remote restart function of the charging monitoring module is realized.

[0052] Specifically, the smart terminal module is a hardware module placed in the charging device; it includes a CPU (storage and operation of embedded software programs in the smart terminal module), active input and output (remote restart function), a 4G module (communication between the smart terminal module and the smart operation and maintenance platform is realized through 4G), and a CAN communication interface (communication between the smart terminal module and the charging monitoring module is realized).

[0053] Therefore, the smart operation and maintenance platform can control the start and stop of the monitoring power supply through the intelligent terminal module, and realize the remote restart of the charging monitoring module and the entire charging equipment.

[0054] In this implementation example, the smart operation and maintenance platform is a big data platform for realizing the smart operation and maintenance of charging equipment. The present invention is limited to the functions of the smart operation and maintenance platform, such as the charging LOG database, BMS protocol library, charging equipment fault intelligent analysis and charging monitoring program version management database.

[0055] The intelligent operation and maintenance platform is implemented based on the server.

[0056] Abnormal shutdown charging log and BMS protocol have coding comparison. The intelligent operation and maintenance platform extracts data from both simultaneously, simulates and replays the charging process, and analyzes the reasons for abnormal shutdown from multiple dimensions such as parameter restrictions, process sequence, and corresponding timeliness of data interaction. The charging monitoring program version management database mainly manages the embedded software program version of the on-site charging equipment and the remote upgrade control of the program.

[0057] When extracting data from both parties simultaneously, accurate extraction can be performed based on the fault time or the generated fault order code.

[0058] The analysis is conducted from multiple dimensions, including parameter restrictions, process sequence, and the timeliness of data interaction. Specifically:

[0059] Parameter limitation: For example, if the maximum allowable current of a vehicle is 100A, and suddenly a frame of data requires a current of 120A, from a safety perspective, the vehicle needs to be shut down and a fault record needs to be made (the vehicle is responsible, the demand current exceeds the maximum allowable charging current);

[0060] Charging process sequence: After the insulation detection process is completed, the charging process needs to enter the pre-charging process. If the vehicle skips the pre-charging process and directly starts normal charging, a process error alarm will be detected.

[0061] The corresponding timeliness of data interaction: mainly for data interaction exceeding the maximum allowed time.

[0062] In this implementation example, the intelligent detection device is mainly composed of a small suitcase shell, a BMS main control module, a charging gun interface, a high-voltage DC contactor (K5 / K6) and a load box, etc. It has CAN communication function and 4G / NET communication function, uses CAN communication function to exchange information with the charging pile, and uses 4G / NET communication function to download the BMS protocol from the smart operation and maintenance platform. It is finally used for conventional process detection of charging equipment and vehicle BMS protocol simulation (see the standard national standard process GB / T27930), and supports intelligent switching of multiple versions of protocols.

[0063] In the intelligent detection device, the charging gun interface is connected to the high-voltage DC contactor (K5 / K6), and the high-voltage DC contactor is connected to the load box. The BMS main control module is the core monitoring module, which runs and stores the embedded software of the intelligent detection device, and has the functions of CAN communication with the charging pile monitoring, 4G / NET communication with the intelligent operation and maintenance platform, and DC contactor control.

[0064] The disclosed embodiment has a built-in smart terminal module in the on-site charging equipment, and uses all the vehicles it serves as samples to automatically generate the BMS protocol for abnormal vehicle charging shutdown and simultaneously download the charging LOG log, and upload it to the smart operation and maintenance platform. The smart operation and maintenance platform performs intelligent analysis on the abnormal shutdown BMS protocol and charging LOG log to locate the cause of abnormal charging shutdown. The intelligent detection equipment downloads the abnormal shutdown BMS protocol from the smart operation and maintenance platform and simulates charging on the local laboratory charging equipment to ensure that the problem can be reproduced.

[0065] According to the abnormal shutdown reason, determine whether to perform a program compatibility upgrade for this BMS protocol. For program upgrade, the intelligent operation and maintenance platform can remotely upgrade the on-site charging equipment and synchronize it to the local laboratory charging equipment. The intelligent detection equipment uses the abnormal shutdown BMS protocol to complete the program compatibility upgrade effect verification on the local laboratory charging equipment, realizing a fully closed-loop compatibility improvement process for the intelligent operation and maintenance of on-site equipment.

[0066] Embodiment 2

[0067] The purpose of this embodiment is to provide a full-closed-loop detection method for intelligent operation and maintenance of charging equipment, which is mainly divided into a BMS protocol and LOG log generation stage, a smart operation and maintenance platform fault diagnosis stage, an intelligent detection device retest stage, a charging monitoring software compatibility upgrade stage and an intelligent detection device final test stage.

[0068] BMS protocol and LOG log generation stage: If the vehicle charging stops abnormally, the intelligent terminal module generates a simulated BMS protocol based on the BMS interaction information, and actively downloads the charging monitoring LOG log, and uploads both to the smart operation and maintenance platform.

[0069] Specifically, the intelligent terminal module will perform the CAN communication synchronous recording function on the vehicle BMS, completely copy the BMS protocol process, and generate a simulated BMS protocol program.

[0070] The intelligent operation and maintenance platform stores the LOG log and BMS protocol in the LOG log database and BMS protocol library respectively, then extracts the data, simulates and replays the charging process, and analyzes the reasons for abnormal shutdown from multiple dimensions such as parameter restrictions, process sequence, and timeliness of data interaction, and classifies the reasons for shutdown. The fault types are divided into pile-side faults (such as charging module faults, lightning arrester faults, etc.), vehicle-side faults, vehicle-pile compatibility faults, etc., and each fault retains the fault analysis message evidence.

[0071] When a vehicle-side fault or a vehicle-pile compatibility fault occurs, the intelligent detection device downloads the abnormal shutdown BMS protocol from the BMS protocol library of the intelligent operation and maintenance platform and saves it in the SD card of the BMS main control module. The BMS main control module retrieves this BMS protocol and performs simulated charging on the laboratory charging equipment to ensure accurate reproduction of the fault.

[0072] Car-side faults or vehicle-pile compatibility faults are classified and safety evaluated to determine whether the charging equipment is compatible with them. If they are compatible, the embedded software program of the laboratory charging equipment is remotely upgraded through the smart operation and maintenance platform.

[0073] The intelligent detection device still uses the BMS simulation protocol of this abnormal shutdown to perform charging process detection on the upgraded laboratory charging equipment to verify the compatibility of the charging equipment with this BMS protocol. After the verification is completed, the intelligent operation and maintenance platform saves the upgraded embedded software version and stores it in the power monitoring program version management database, and remotely upgrades the embedded software of the on-site charging equipment through the intelligent terminal module.

[0074] The remote upgrade and remote restart control process is as follows:

[0075] See again the attached Figure 2 As shown, remote upgrade and remote restart involve the smart operation and maintenance platform, smart terminal module, charging monitoring module, monitoring power relay and monitoring power supply. The smart terminal module contains active input and output. The active output controls the monitoring power relay. The relay normally closed contact controls the on and off of the monitoring power supply line. The normally open contact is used for relay status feedback. Therefore, the smart operation and maintenance platform can control the start and stop of the monitoring power supply through the smart terminal module, and realize the remote restart of the charging monitoring module and the charging equipment. Faults such as program deadlock, signal attenuation, and switch malfunction can be eliminated through the remote restart function.

[0076] Remote upgrade process Figure 3 As shown, the smart operation and maintenance platform stores the verified embedded software program in the charging monitoring program version management database, and downloads the program version to the smart terminal module in the charging device for upgrade. The smart terminal module sends an embedded software upgrade request to the charging monitoring module, and the charging monitoring module responds to the program upgrade in the idle period and non-charging state according to its own status and the equipment operation period. After the upgrade is completed, the charging monitoring module informs the smart terminal module that the program upgrade is complete, and the smart terminal module controls the charging monitoring module and the entire charging device to restart, so that the remote upgrade is completed.

[0077] The upgrade scheme of this embodiment makes full use of the inherent physical communication interface of the charging device body to establish interaction, uses patrol synchronization update, and adapts to the mainstream charging device monitoring platform; when the upgrade starts, the "start download frame" instruction is sent first; when the start download command sent by the smart terminal module is received, the charging device should determine whether to allow the program update based on the function and status of the current version, and feedback the result to the smart terminal module; the smart terminal module sends a "request interval command frame" instruction to the charging device. When the source program to be updated is large, the smart terminal module will package the source program in units of 1KB, and send a "start package command frame" instruction to the charging device, including the first address of the group. After receiving this instruction, the power control module reserves the corresponding space and replies to the charging control module with a "start package response frame".

[0078] Examples:

[0079] Abnormal shutdown failures of vehicle charging frequently occur in a certain area. The on-site phenomenon is that the vehicle-pile handshake stage passes, the parameter configuration stage passes, and the charging startup stage fails after a short charging time.

[0080] The intelligent terminal module generates the BMS protocol for this charging, and downloads the charging monitoring LOG and uploads it to the intelligent operation and maintenance platform. The intelligent operation and maintenance platform stores the LOG and BMS protocol in the LOG database and BMS protocol library respectively, and then extracts the data to simulate and replay the charging process. It is found that when the vehicle is charging, the demand current value in a certain frame of the charging demand parameter is greater than the maximum allowable charging current value of the vehicle. The charging equipment stops charging for the protection of the vehicle, and the fault type is a vehicle-side fault.

[0081] The intelligent detection device downloads the BMS protocol for this charging and performs simulated charging on the laboratory charging equipment to ensure that the fault can be reproduced.

[0082] Because this version of vehicles has been put on the market on a large scale in the region and accounts for a large proportion, charging operators require equipment manufacturers to be compatible. Equipment manufacturer engineers analyzed from the two aspects of compatibility and safety, and used the minimum of the maximum allowable charging current value and the actual current value required by the vehicle as the required current of the charging equipment, that is, when the vehicle demand current is greater than the maximum allowable charging current, the maximum allowable charging current value is used as the response current output.

[0083] After the embedded software is written, it is uploaded to the intelligent operation and maintenance platform. The platform remotely upgrades the embedded software of the laboratory charging equipment to be compatible with this version of the vehicle. The intelligent detection device uses the BMS protocol of this version of the vehicle to simulate charging on the laboratory charging equipment to verify the compatibility upgrade of the program.

[0084] After the program is verified to be qualified, the smart operation and maintenance platform will save this version of the program in the power monitoring program version management database, and remotely upgrade the on-site equipment through the smart terminal module.

[0085] Those skilled in the art should understand that the modules or steps of the present invention described above can be implemented by a general-purpose computer device, or alternatively, they can be implemented by a program code executable by a computing device, so that they can be stored in a storage device and executed by the computing device, or they can be made into individual integrated circuit modules, or multiple modules or steps therein can be made into a single integrated circuit module for implementation. The present invention is not limited to any specific combination of hardware and software.

[0086] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
