At present, multiple charging modules are generally charged by the master-slave charging module current sharing method, that is, the master charging module is accurately found, the master charging module issues instructions, and the slave charging module works normally according to the instructions. However, when the main charging module is abnormal, including the duplication of the main charging module or the loss of connection of the main charging module, if there is no stable processing mechanism, it will cause the entire charging system to be paralyzed, resulting in unexpected results.

[0003] The existing method for detecting and handling abnormalities in the main charging module is to repeat the detection with multiple delays through the main charging module. The detection process is cumbersome. When the main charging module is detected to be repeated, multiple main charging modules are exited in real time, and the main charging modules are re-screened in the next cycle. The main search process also requires several cycles to find the accurate main charging module. During the time of searching for the main charging module, due to the repetition of the main charging module, the slave charging module will not know which main charging module to follow, resulting in fluctuations in the entire system.

[0043] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.

[0044] In order to make the purpose, technical solutions and advantages of the present invention more clear, specific embodiments will be described below in conjunction with the accompanying drawings.

[0045] Figure 1 The present invention provides a flowchart for implementing a method for handling an abnormality of a main charging module. In this embodiment, the problem of abnormality of the main charging module is solved through real-time master search operation. The master search (i.e., searching for the main charging module) is always carried out, rather than in the traditional sense, after the charging pile is powered on, it will no longer search for the master after finding the host, unless the main charging module is abnormal, then it will search for the master again. In this way, if there is a situation where the main charging module is repeated or lost, since each charging module is continuously searching for the master, the next time the master search operation is performed, as long as the communication is normal, the correct and unique main charging module will naturally be generated. The following is a detailed description of the method for handling the abnormality of the main charging module:

[0046] Step 101, receiving a current sharing message, and marking the charging module number according to the current sharing message.

[0047] Each time a current sharing message is received from other modules, it is the beginning of a process, but the master-seeking operation is not performed in every process. A complete process of real-time master-seeking operation is based on the standard that the delay count value marked with the machine number is equal to the preset count value. The pre-designed value is set according to the number of charging modules. After receiving the current sharing messages from all other charging modules connected to the same CAN bus, a master-seeking operation is completed.

[0048] The operation of marking the charging module machine number here may include: according to the received current sharing message, assigning the machine number of the charging module corresponding to the current sharing message to the machine number marking variable, for example, setting a 64-bit machine number marking variable, receiving the current sharing message sent by charging module No. 1, if the machine number of charging module No. 1 is greater than the machine number of the current charging module, then clearing Bit1 of the machine number marking variable to 0, if the machine number of charging module No. 1 is less than the machine number of the current charging module, then setting Bit1 of the machine number marking variable to 1; similarly, when receiving the current sharing message sent by other charging modules, the corresponding Bit1 of the machine number marking variable is also set. Finally, if the machine number of the current charging module is the smallest machine number, the machine number marking variable is equal to 0, if the machine number of the current charging module is not the smallest machine number, then the machine number marking variable is not equal to 0, and subsequently it can be determined whether the current charging module is the main charging module according to the value of the machine number marking variable.

[0049] In one embodiment, see Figure 2 The schematic diagram of the method for handling the abnormality of the main charging module includes: after receiving the current sharing message, clearing the reception abnormality flag and the reception abnormality count value in the current charging module. In order to record and handle the reception abnormality in time when it occurs in the current process.

[0050] See also Figure 2 , after receiving the current sharing message, it also includes: according to the current value in the current sharing message, calculating the sum of the current value and the previous current accumulated value to obtain the accumulated current value. The purpose of the accumulated current value here is to subsequently determine that the current charging module is the host, so that the current sharing value can be calculated based on the accumulated current total, so as to send the current sharing value to each slave charging module for current sharing. Among them, when the sender of the current sharing message has sent a current sharing message before, the current value in the currently received current sharing message will not be accumulated to avoid errors in the calculation of the current average.

[0051] It should be noted that after receiving the current equalizing message, the receiving abnormal flag and the receiving abnormal count value in the current charging module can be cleared first, and then the charging module machine number can be marked according to the current equalizing message, and then the current value and the previous current accumulated value can be calculated based on the current value in the current equalizing message.

[0052] Step 102: When the current sharing message is sent by the slave charging module, the machine number marking delay count is accumulated.

[0053] In one embodiment, see Figure 2 , before this step, it also includes: according to the current sharing message, detecting whether the current sharing message is sent by the slave charging module, that is, whether the received information is the slave. The current sharing message carries the machine number of the charging module, and the charging module with the largest or smallest machine number can be specified as the main charging module. When the machine number of the charging module carried in the current sharing message is not the largest machine number or the smallest machine number, the current sharing message is sent by the slave charging module.

[0054] When the current sharing message is sent by the slave charging module, the current charging module may be the master charging module, and this step is executed to add 1 to the delay count of the machine number.

[0055] When the current sharing message is not sent by the slave charging module, the current charging module may be a slave charging module, and whether the current charging module is a slave charging module is detected;

[0056] When the current charging module is a slave charging module, slave processing is performed to end this process. Here, the slave processing includes the current charging module controlling its own current to be the current sharing value in the current sharing message.

[0057] When the current charging module is not a slave charging module, it means that this machine is the host, and the host is repeated, and this process ends.

[0058] Step 103, detecting whether the current charging module is the main charging module according to the machine number marking delay counting result and the machine number marking information.

[0059] In one embodiment, see Figure 2 , this step includes:

[0060] Check whether the delay count of the machine number label is equal to the pre-designed value; when the delay count of the machine number label is less than the pre-designed value, end this process; when the delay count time of the machine number label is equal to the pre-designed value, clear the delay count of the machine number label; determine the main charging module according to the machine number labeling information, and check whether the current charging module is the main charging module.

[0061] Optionally, the preset count value is determined based on the total number of charging modules connected to the same CAN bus. For example, if there are 10 charging modules connected to the same CAN bus, the pre-designed value can be any value greater than 9. The current charging module is excluded here. Since the current sharing message of the same charging module may be received multiple times, the pre-designed value is generally set to be greater than 9.

[0062] When the delay count of the machine number is equal to the pre-designed value, it means that the current sharing messages of all charging modules have been received, and the main charging module can be determined. When the delay count of the machine number is less than the pre-designed value, it means that the current sharing messages of all charging modules have not been received, and the current process ends. When a new current sharing message is received, a new process starts again from step 101.

[0063] The machine number marking delay count is cleared to zero, and the next process needs to find the main restart module again, and then the machine number marking delay count needs to be restarted, and this process is repeated.

[0064] When determining the main charging module according to the machine number marking information, the charging module with the smallest machine number in the machine number marking information is determined as the main charging module according to the regulations. After determining the main charging module, it can be determined whether the current charging module is the main charging module according to the value of the machine number marking variable. That is, when the value of the machine number marking variable is 0, the current charging module is determined to be the main charging module, and when the value of the machine number marking variable is not 0, the current charging module is determined to be the slave charging module.

[0065] Step 104, when the current charging module is the main charging module, host processing and data reset are performed.

[0066] In one embodiment, the operation of host processing includes: determining the number of corresponding charging modules according to the received current sharing message. Since each charging module sends a current sharing message to the CAN bus, after receiving the current sharing message, if the current sharing message sent by this charging module has not been received before, the number of charging modules is increased by 1. If the current sharing message sent by this charging module has been received before, the current number of charging modules remains unchanged. Finally, the current charging module is added to obtain the total number of charging modules. The current values ​​corresponding to all charging modules are accumulated, and finally the current value of the current charging module is added to obtain the total current value. The total current value is divided by the total number of charging modules to obtain the current sharing value.

[0067] After the host completes the processing, because the information required for the host search operation has been recorded in the current process, a data reset operation is performed, that is, the received current sharing message is deleted, including the current value, voltage value, machine number and other information of other charging modules.

[0068] See also Figure 2 When the current charging module is not the main charging module, the data is reset and the process ends.

[0069] The above-mentioned method for handling the abnormality of the main charging module receives the current sharing message and marks the charging module machine number according to the current sharing message; when the current sharing message is sent by the slave charging module, the machine number marking delay count is accumulated; according to the machine number marking delay count result and the machine number marking information, it is detected whether the current charging module is the main charging module; when the current charging module is the main charging module, the host processing and data reset are performed, so that the master search operation can be carried out in real time and continuously. When the main charging module is repeated, the process is directly terminated, and the next process directly searches for the master again, replacing the abnormal detection of the main charging module being lost or repeated in the prior art, thereby avoiding the cumbersome process of abnormal detection, reducing the complexity of abnormal processing, and further reducing the processing time of multiple delayed detections in the abnormal processing process before re-searching the master in the next cycle, reducing the system fluctuation problem that occurs in the abnormal processing process in the prior art. The embodiment of the present invention can shorten the system oscillation time and quickly locate the accurate host.

[0070] In addition, since the master search operation is performed in real time, if the main charging module is suddenly disconnected or unplugged, the current charging module is likely to become the main charging module, realizing smooth switching from the slave charging module to the main charging module. If a new charging module is suddenly added, the current charging module was the main charging module at the previous moment, and at the next moment, because the newly inserted charging module has a smaller machine number, the current charging module changes from the main charging module to the slave charging module, realizing smooth switching from the main charging module to the slave charging module.

[0071] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.

[0072] The following is an embodiment of the device of the present invention. For details not described in detail therein, reference may be made to the corresponding method embodiment described above.

[0080] In a possible implementation, after the receiving module 301 receives the current sharing message, the processing module 305 is further configured to:

[0081] The reception abnormality flag and reception abnormality count value in the current charging module are cleared.

[0082] In a possible implementation, when the current sharing message is sent by the slave charging module, before the counting module 303 performs the machine number marking delay count accumulation, the detection module 304 is further used to: detect whether the current sharing message is sent by the slave charging module according to the current sharing message;

[0083] The detection module 304 is further used to: when the current sharing message is not sent from the charging module, detect whether the current charging module is a slave charging module;

[0084] The processing module 305 is also used to perform slave processing when the current charging module is a slave charging module, thereby terminating the current process.

[0085] In a possible implementation, after the detection module 304 detects whether the current charging module is a slave charging module, the processing module 305 is further configured to:

[0086] When the current charging module is not the slave charging module, this process ends.

[0087] In a possible implementation, when the detection module 304 detects whether the current charging module is the main charging module according to the machine number labeling delay counting result and the machine number labeling information, it is used to:

[0088] Check whether the machine number marking delay count is equal to the pre-designed value;

[0089] When the machine number marking delay count is less than the pre-designed value, the process ends; when the machine number marking delay count time is equal to the pre-designed value, the machine number marking delay count is cleared;

[0090] According to the machine number labeling information, the main charging module is determined, and it is detected whether the current charging module is the main charging module.

[0091] In a possible implementation, after the receiving module 301 receives the current sharing message, the counting module 303 is further configured to:

[0092] According to the current value in the current sharing message, calculate the sum of the current value and the previous current accumulated value;

[0093] When the processing module 305 performs host processing, it is used to: calculate the current sharing value according to the number of received current sharing messages and the calculated total current value.

[0094] In a possible implementation, after the detection module 304 detects whether the current charging module is the main charging module, the processing module 305 is further configured to:

[0095] When the current charging module is not the main charging module, data is reset and the process ends.

[0096] The above-mentioned main charging module abnormality processing device receives the current sharing message through the receiving module, and the recording module marks the charging module machine number according to the current sharing message; when the current sharing message is sent by the slave charging module, the counting module performs the machine number marking delay count accumulation; according to the machine number marking delay count result and the machine number marking information, the detection module detects whether the current charging module is the main charging module; when the current charging module is the main charging module, the processing module performs host processing and data reset, so that the main search operation can be carried out in real time and continuously. When the main charging module is repeated, the process is directly terminated, and the next process directly searches for the main again, replacing the loss of connection or repeated abnormal detection of the main charging module in the prior art, thereby avoiding the cumbersome process of abnormal detection, reducing the complexity of abnormal processing, and further reducing the processing time of multiple delayed detections in the abnormal processing process before re-searching the main in the next cycle, reducing the system fluctuation problem in the abnormal processing process in the prior art. The embodiment of the present invention can shorten the system oscillation time and quickly locate the accurate host.

[0097] In addition, since the master search operation is performed in real time, if the main charging module is suddenly disconnected or unplugged, the current charging module is likely to become the main charging module, realizing smooth switching from the slave charging module to the main charging module. If a new charging module is suddenly added, the current charging module was the main charging module at the previous moment, and at the next moment, because the newly inserted charging module has a smaller machine number, the current charging module changes from the main charging module to the slave charging module, realizing smooth switching from the main charging module to the slave charging module.
