[0002] With the popularization of new energy in low-speed electric fields such as aerial work platforms, golf carts, floor scrubbers, transporters, and electric racing, the demand for chargers is growing.

[0003] In the traditional use of chargers: ① When customers replace batteries, they need to change to different charging strategies, and often need to manually update the firmware or charging strategy of each charger one by one; ② When a fault occurs, there is no simple way to troubleshoot the fault; ③ For some special operations, such as battery repair operations, it is necessary to manually go to the site to find the charger, manually change the charging strategy or disassemble the battery to use professional repair equipment.

[0004] In summary, traditional chargers usually only have basic charging functions and lack remote control and monitoring capabilities, resulting in huge maintenance costs and cycles, which need to be improved. Summary of the invention

[0005] The object of the present invention is to provide a charging method supporting remote services to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] See also Figure 1 , a charging method supporting remote service, comprising the following steps:

[0027] Step 1, complete the preparation work, correctly connect the charger to the diagnostic equipment, turn on the charger power, ensure that the CAN bus is active, and the charger supports the 14229 protocol;

[0028] Step 2, select the DID library in the diagnostic software of the diagnostic device and select the corresponding DID;

[0029] Step 3: Configure data parameters based on DID;

[0030] Step 4, make a write request after the data parameters are modified;

[0031] Step 5, verify the write request;

[0032] Step 6: Confirm the data parameter modification and writing;

[0033] Step 7, verify and test the new data after the data parameters are modified;

[0034] Step 8: Record and save the DID modification information.

[0035] In a specific embodiment: The ISO 14229 standard defines the communication protocol between the electronic control unit (ECU) and external diagnostic equipment in the vehicle network system, mainly for fault detection, diagnosis and repair. This standard is widely used in the automotive industry to ensure effective communication between diagnostic tools and vehicles from different manufacturers by specifying a series of diagnostic services. Using the ISO 14229 standard, technicians can read fault codes, clear fault codes, monitor vehicle status, and update firmware.

[0036] DID (Data Identifier) ​​is an identifier used for vehicle diagnosis, which is used to identify and obtain specific parameter data. Each DID corresponds to a specific data item of the vehicle, such as sensor data, status information, etc.

[0037] CAN bus is a multi-master serial communication protocol with high anti-interference and long-distance transmission capability, suitable for complex industrial environments and automotive applications.

[0038] The charger is designed in full compliance with ISO 14229 standards, ensuring international adaptability and interoperability of the equipment.

[0039] The hardware structure includes:

[0040] A charging control system, used to control whether the charger is charging;

[0041] CAN bus interface, used to establish charger and remote communication, meets ISO 14229 standard, and enables communication between electronic control unit (ECU) and external diagnostic equipment in vehicle network system;

[0042] The power management module is used to control the output voltage to match the charging effect under different charger parameters;

[0043] The voltage and current detection module is used to detect the charging voltage and current, provide timely feedback and obtain charging information, and detect the charging effect after the data parameters are modified.

[0044] All are centrally controlled by a microprocessor to ensure efficient data processing and communication.

[0045] Software architecture: The software includes the underlying driver, operating system, communication protocol stack and application layer program. Through this layered design, the software can efficiently handle CAN bus communication and data management.

[0046] Realize the functions of remote charger upgrade, remote self-check, remote switching of charging strategy, and reading charger status and charger log.

[0047] See also Figure 1 , Figure 1 This is the firmware upgrade process. The diagnostic device, i.e., T_box, detects the charger information to determine whether there is the latest firmware (new data value after data parameters are modified). If so, a security check is performed. If the check passes, a request to transmit the firmware package is started. The charger clears the backup area, receives and stores the firmware package, and performs verification after receiving it. After verification, the firmware program is switched to run.

[0048] In this example: See Figure 1 In step 2, start the diagnostic software on the diagnostic device and update it to the latest DID library. On the interface of the diagnostic software, browse or search for the specific DID to which data needs to be written; each DID corresponds to a specific parameter or configuration setting in the charger.

[0049] In this example: See Figure 1 In step 3, click the selected DID to enter the data configuration interface and enter new data values ​​as needed.

[0050] For example, if the DID is associated with a charging policy, enter the appropriate policy code.

[0051] In this example: See Figure 1 , in step 4, after confirming the input new data value, a write request is sent to the charger control system; the diagnostic tool will send a write command in a specific format through the CAN bus.

[0052] In this example: See Figure 1 ,In step 5, after receiving the data write request, the charger control system will perform internal verification. ,If the data is valid and the system allows changes, the charger control system will send a confirmation signal to the ,diagnostic device.

[0053] In this example: See Figure 1 In step 6, after the diagnostic device receives the confirmation signal, the diagnostic device displays a message indicating that the data parameter modification is successfully written.

[0054] In some cases, some data writing may require the charger to be restarted to fully take effect. For example, data writing may rely on specific processes or services. If these processes or services do not correctly update their status or respond to new data after data writing, restarting these processes or services can restore their normal status and make the newly written data effective.

[0055] In this example: See Figure 1 In step 7, after the new data value of the modified data parameter is written, the charger is re-tested using diagnostic equipment to ensure that the parameters have been updated as expected; actual vehicle testing (charging testing of equipment such as golf carts and transporters) is performed to check the impact of data changes on charger performance.

[0056] In this example: See Figure 1 ,In step 8, record the details of all DID changes and save the diagnostic report, with details including time, date, changed DID and its old and new values.

[0057] The detailed information of DID changes stored ensures the convenience of subsequent maintenance and troubleshooting.

[0058] The present invention supports 14229 remote services and DID configuration, so that users can remotely control the charger, upgrade the firmware, monitor the status, and remotely troubleshoot problems through websites or other remote terminals, thereby improving charging efficiency and user experience, and realizing batch control of chargers, verifying charger strategies, and monitoring equipment.

Therefore, the embodiments should be considered as exemplary and non-restrictive in all respects.

[0060] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
