DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Unless otherwise defined, the technical terms or scientific terms used in the embodiments of this specification shall have the ordinary meanings as understood by those skilled in the art to which this specification pertains. The terms "first", "second" and similar terms used in the embodiments of this specification do not denote any order, quantity or importance, but are merely set up to avoid confusion of components.

[0025] Unless the context otherwise requires, throughout this specification, "a plurality of" means "at least two", and "comprising" is interpreted in an open, inclusive sense, i.e., "including, but not limited to". In the description of this specification, the terms "one embodiment", "some embodiments", "exemplary embodiments", "examples", "specific examples" or "some examples", etc. are intended to indicate that specific features, structures, materials or characteristics related to the embodiment or example are included in at least one embodiment or example of this specification. The schematic representations of the above terms do not necessarily refer to the same embodiment or example.

[0026] Next, the technical solutions in the embodiments of this specification will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this specification. Obviously, the described embodiments are only a part of the embodiments of this specification, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this specification without creative efforts shall fall within the scope of protection of this specification.

[0027] As described in the background art, with the rapid development of the new energy vehicle industry, charging piles, as key supporting facilities, have been widely used and rapidly built globally. However, as a complex automotive electronic product, the software and hardware of charging piles need to be frequently upgraded or downgraded according to market demands, laws and regulations, and customer requirements. For the same manufacturer, the charging piles in different regional markets may have inconsistent software and hardware versions due to different usage scenarios, regulatory requirements or customer needs. This difference has led to the need for an efficient compatibility solution in practical applications to meet the functional requirements of various types of charging piles and reduce the cost of re-design and production.

[0028] However, the current charging pile compatibility solutions in the market mostly rely on mechanical structure adjustments. This method is not only cumbersome and inefficient in operation, but also difficult to meet the requirements of rapid upgrading or downgrading. At the same time, traditional compatibility solutions often ignore the possibility of combining software and hardware, resulting in insufficient flexibility in dealing with diverse requirements.

[0029] Therefore, it is necessary to provide a control method for charging piles compatible with multiple models to solve the above problems.

[0030] Based on the above inventive concept, the control method for charging piles compatible with multiple models provided in the embodiments of this specification will be described exemplarily below.

[0031] An embodiment of this specification provides a charging pile 100 compatible with multiple models. As Figure 1 shown, it includes: At least one charging gun 101, a temperature sensor 102, and a communication control unit 103. The charging gun 101 is used to connect the device to be charged and output electric energy to the device to be charged. The communication control unit 103 is used to determine the hardware level of the charging pile 100 and update the configuration information for the charging pile 100 based on the hardware level. The hardware level includes Level 1 (Hardware Version 1.0, HW1.0) and Level 2 (Hardware Version 2.0, HW2.0). The temperature sensor 102 is used to sample the temperature of the device to be charged and transmit it to the communication control unit 103 when the hardware level is Level 2. In specific implementation, by connecting and disconnecting the temperature sensor 102, the hardware level can be arbitrarily switched between HW1.0 and HW2.0. When switched to HW2.0, the charging pile 100 has an additional function of high-voltage circuit temperature sampling through the temperature sensor 102 compared with HW1.0.

[0032] In practical applications, the temperature sensor 102 (T-sensor) can be installed in the connector harness of the communication control unit 103 (T-BOX). The specific selection of the temperature sensor 102 can be a thermistor NTC or other types of sensors. In this embodiment, the thermistor is taken as an example for illustration. In one example, the resistance value range of the thermistor is -40°C to 120°C, and the actual use range is -30°C to 120°C. Of course, other thermistors can also be adjusted and replaced according to requirements, and the embodiments of the present invention do not limit this.

[0033] The charging pile 100 may also include other structures, such as a card reader unit for selecting a corresponding target card reader from multiple card readers for the charging station, an emergency stop switch for urgently cutting off the power supply of the charging pile 100, and a level switching unit for switching the hardware level of the charging pile 100 to level two by connecting a temperature sensor or switching the hardware level of the charging pile 100 to level one by disconnecting the temperature sensor. Additionally, the charging pile 100 may also include a maintenance small door, which refers to a security door device for controlling physical access on the charging pile 100, usually located near internal components that need to be maintained or debugged (such as controllers, battery packs, wiring harnesses), and is equipped with an access control sensor, that is, an electronic lock or sensor, which only allows authorized personnel to open it through specific methods (such as passwords, digital keys) to prevent unauthorized personnel from opening it casually. This maintenance small door is activated at HW2.0 and disabled at HW1.0 to achieve avoiding unauthorized operations or tampering with internal data (such as charging records, user information, system configurations) by restricting physical access, and it can be linked with the Energy Management System (EMS). If an illegal opening is detected, it can trigger an alarm or disable key functions.

[0034] Furthermore, the card reader unit can be a device for plugging in and unplugging card readers, or multiple card readers can be integrated together through the setting of switches and circuits, and the corresponding card reader can be plugged in when in use. Card readers can include various types. According to the currently common models and specifications, in one embodiment, the card reader unit can switch four card reader CCV models, including four models of card readers such as OPM-C60, IM15, Castles, and Payters. In one example, the switch is achieved by replacing the CCV, and the installation can be completed by unplugging and plugging the CCV connector.

[0035] In another example, the four card readers are integrated into one card reader. These four card readers share the power supply, communication lines, and main control chip, and the currently used card reader is selected through an internal switch.

[0036] Furthermore, the temperature sensor 102 can be installed on the charging pile 100 in a plug-and-play form, or can be accessed and disconnected through the setting of switches and circuits. In one example, for the switch through the plug-and-play method, two sets of wiring harnesses need to be prepared. One set contains a T-sensor for HW2.0, and the other set does not contain a T-sensor for HW1.0. When a version switch is required, only the corresponding wiring harness needs to be replaced to complete the adjustment of the hardware part. The specific switch, that is, the installation is as Figure 2As shown in the figure, the installation solution of the temperature sensor 102 is as follows: The wire harness where the T-sensor is located is the connector wire harness of the T-BOX. The EMS transmits information to the T-BOX through the CANFD bus. Among the pin feet of the original HW1.0 T-BOX, Pin35 and Pin36 on the connector J1 are used to provide 12V power. Among the pin feet of the HW2.0 T-BOX, the pin 36 on the connector J1 is deleted, and then the 12V power supply wire of the pin 35 is modified and connected to the temperature sensor 102. The temperature sensor can be a thermistor, with its T+ connected to Pin35 of the T-BOX J1 and T- connected to Pin19 (Power_GND) of the T-BOX J1.

[0037] In another example, a single-pole double-throw switch is arranged in a wire harness to connect and disconnect the temperature sensor 102. Then it is connected to Pin35 and Pin36 of the T-BOX.

[0038] The embodiment of this specification provides a control method for a charging pile compatible with multiple models, such as Figure 3 shown, including: S301. Determine the current hardware level of the charging pile according to the working state of the temperature sensor.

[0039] Specifically, when it is detected that the temperature sensor is not working, it is determined that the current hardware level of the charging pile is level one, that is, HW1.0. When it is detected that the temperature sensor is working, it is determined that the current hardware level of the charging pile is level two, that is, HW2.0.

[0040] Still using the above example, when the temperature sensor is a thermistor, after the whole machine is powered on, the EMS receives the temperature signal value from the T-BOX through the CANFD bus for hardware version judgment. The T-BOX samples the resistance value change of the thermistor with a period of 1000ms, converts it into the corresponding voltage value, and calculates the temperature value through A / D conversion, with an accuracy range within 3°C. As shown in the following table: MCU_Monitor(mv) T(℃） HW configuration [0,24] 120 2.0 24-387 -30~120 2.0 387-587 -30 2.0 ≥587 215 1.0 If the detected sampled voltage value is within the range of [0, 587) mV, the calculated temperature value will be between -30°C and 120°C, and it is determined as HW2.0 at this time; if the sampled voltage value ≥ 587 mV, it is determined as HW1.0. The specific judgment logic on the EMS side is as follows: within 1 second after power-on, the default hardware version is set to 0; subsequently, within 5 seconds, if a signal with a temperature of 215°C and a duration exceeding 3.75 seconds is received, the hardware is determined to be HW1.0; if a signal with a temperature within the range of [-30, 120]°C and a duration exceeding 3.75 seconds is received, the hardware is determined to be HW2.0. Once the hardware version is confirmed, the version information cannot be changed by any other means. At the same time, when switching from HW1.0 to HW2.0, the software part upgrades SW2.X to SW3.X to match the new functions, including the access control sensor for the maintenance small door, the in-package relay diagnosis function, and the temperature sampling function. This combination of software and hardware simplifies the operation process and significantly improves compatibility.

[0041] It should be noted that the values in the above table can be adjusted according to actual needs and the specifications of the thermistor, and the embodiments of the present invention do not limit this.

[0042] S302. Generate configuration information corresponding to the hardware level according to the hardware level of the charging pile.

[0043] In specific implementation, according to the hardware status and hardware level of the charging pile, configuration information corresponding to the hardware level and hardware status is generated. The hardware status is used to distinguish the model of the currently connected card reader and whether it includes an emergency stop switch, etc. According to the different card reader models and whether an emergency stop switch is included, changes are made at the corresponding positions in the configuration information.

[0044] Still using the above example, the 4 CCV models are OPM-C60, IM15, Castles, and Payters, which are respectively used for pile bodies with and without an emergency stop switch (ESD). The switching process is achieved by generating a "global_config.json" configuration file, which includes two fields, HW_config and SW_config. The HW_config field is used to activate or deactivate the 4 CCV models, represented by "true" or "false"; the SW_config field is used to set the ESD or Non-ESD function, also represented by "true" or "false". The configuration file is packaged into a FOTA.tar.gz folder through the FOTA tool.

[0045] In this step, a digital certificate can also be generated based on the configuration information. The configuration information corresponds one-to-one with the digital certificate, which is used to ensure the correspondence of files in the subsequent update of the configuration information.

[0046] Still using the above example, after packaging into the FOTA.tar.gz folder, the digital certificate "TboxPublic.pem" is correspondingly generated.

[0047] S303. Update the configuration information for the charging pile.

[0048] During specific implementation, use the configuration information generated in step S302 to update the original configuration information in the charging pile. If there is a digital certificate, verify the configuration information based on the digital certificate, and update the configuration information for the charging pile after successful verification.

[0049] Still using the above example, push the FOTA.tar.gz file to the / mnt / sdcard / emmc / fota / tmp directory of the T-BOX, and at the same time push the TboxPublic.pem file to the / usrdata directory. Then, after executing the upgrade command to trigger the FOTA upgrade, the T-BOX sends the result to the EMS for storage in the EEPROM. The specific upgrade process is as follows: First, use the PC to locally generate the "global_config.json" configuration file to define the required CCV model and function configuration; S2 Package the configuration file into the FOTA.tar.gz folder through the FOTA tool and generate the digital certificate "TboxPublic.pem"; S3 Use the adb command to push the FOTA.tar.gz file to the / mnt / sdcard / emmc / fota / tmp directory of the T-BOX and push the TboxPublic.pem file to the / usrdata directory; S4 Execute the following command to trigger the upgrade: echo "(TESTER)UPDATE -m 2 -p / mnt / sdcard / emmc / fota / tmp" > / dev / hflash_vtty0. After the upgrade is completed, the T-BOX sends the result to the EMS through the Ethernet for storage in the EEPROM. After the charging pile is powered on, the EMS reads the stored value of the corresponding CCV model from the EEPROM and executes the corresponding program. If the CCV hardware is replaced, for example, when replacing it with the OPM-C60 model, first set the HW_config field to "true" in the configuration file, and then unplug the original CCV connector and insert the new OPM-C60 hardware. If the CCV hardware does not match the configuration file, the EMS will report the communication timeout fault code DTC and disable the current CCV hardware to ensure system security.

[0050] The above method has significant advantages in practical applications. For example, during the actual commissioning process of a new energy vehicle charging station, technicians successfully upgraded a batch of HW1.0 charging piles to HW2.0 by replacing the wiring harness and performing FOTA upgrade operations, meeting the customer's requirements for new functions. At the same time, when deploying charging piles in different countries and regions, by modifying the "global_config.json" configuration file, it quickly adapted to the local laws and regulations. In addition, this method also provides a convenient operation means for engineering commissioning personnel, facilitating problem reproduction and function rollback.

[0051] In summary, the present invention realizes multi-type compatibility and upgrade and downgrade of energy storage charging piles through a combination of software and hardware. The design and application of the T-sensor, the generation and upgrade process of the FOTA configuration file, and the communication processing of the EMS for the CCV together constitute a complete technical solution. These technical means not only solve the compatibility problems existing in the prior art, but also greatly reduce the R & D and production costs, providing strong support for the development of the new energy vehicle charging field.
