[0017] The technical solution of the present application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described below are only part of the embodiments of the present application, not all of the embodiments.

[0018] See also Figure 1 As shown, a multi-channel battery simulator provided by an embodiment of the present application includes: A plurality of power channel modules 110, each power channel module 110 is used to simulate a battery; A main control unit 120; The FPGA (Field Programmable Gate Array) module 130 is internally provided with a plurality of cache units 131 corresponding to the plurality of power channel modules 110 one by one, and a plurality of serial port transceiver modules 132 corresponding to the plurality of power channel modules 110 one by one; each cache unit 131 is connected to the corresponding serial port transceiver module 132 through a synchronous switch unit 133, and the plurality of cache units 131 are connected to the main control unit 120 through a communication bus; the communication mode between each serial port transceiver module 132 and the corresponding cache unit 131 is configured as a half-duplex communication mode; each synchronous switch unit 133 is controlled by the main control unit 120; The communication mode between each power channel module 110 and the serial port transceiver module 132 is configured as a half-duplex communication mode.

[0019] In the embodiment of the present application, multiple groups of cache units 131 and serial port transceiver modules 132 corresponding to multiple power channel modules 110 are set inside the FPGA module 130, and the communication between each group of cache units 131 and the serial port transceiver module 132 can be connected and disconnected through the synchronous switch unit 133, so that when synchronous control is required, after waiting for the output adjustment control frames of all power channel modules 110 that need to be synchronized to be cached in the cache unit 131, the synchronous switch unit 133 is turned on to complete the synchronous transmission to the serial port transceiver module 132, thereby completing the synchronous control of multiple power channel modules 110, and reducing the situation of data packet loss due to large amount of transmitted data. In the embodiment of the present application, by constructing a cache unit 131 corresponding to each power channel module 110 inside the FPGA module 130, and constructing a half-duplex communication architecture between the cache unit 131, the serial port transceiver module 132, and the power channel module 110, the demand for communication resources can be effectively reduced under the premise of achieving synchronous transmission with low packet loss rate, which is convenient for ensuring the realization of other functions and reducing costs.

[0020] The above-mentioned serial port transceiver module 132 and the power channel module 110 can achieve half-duplex communication through a 485 communication module, and a 485 isolation communication module can be further selected according to actual needs.

[0021] The power channel module 110 has a built-in controller, so that half-duplex communication with the serial port transceiver module 132 can be achieved.

[0022] The number of the power channel modules 110 is set according to actual needs. In some embodiments, 32 channels, that is, 32 power channel modules 110, are preferred, which is sufficient to meet the needs of most BMS tests.

[0023] The cache unit 131 may be a FIFO cache unit.

[0024] The cache unit 131 , the serial port transceiver module 132 , and the power channel module 110 sequentially construct a half-duplex communication architecture, and can implement half-duplex communication.

[0025] Specifically, in the embodiment of the present application, a half-duplex communication architecture is adopted, and the FIFO buffer unit can be used to store the output adjustment control frame only when the output adjustment control frame needs to be sent down, and the FIFO buffer unit can be used to store the data uploaded by the power channel module 110 when the power channel module 110 uploads data. On the basis of realizing the time-sharing storage of downlink data and upload data, the half-duplex communication architecture is cleverly used to complete the correct and high-speed transmission of data without building a full-duplex communication architecture, so that there is no need to set up two FIFO buffer units for downlink and upload separately. In addition, because the FIFO buffer unit is adopted, when data needs to be overwritten, there is no need to perform complex writing and reading logic control, and it is only necessary to ensure that the data is read by the serial port transceiver module 132 and the main control unit 120 before being overwritten.

[0026] The synchronous switch unit 133 can connect and disconnect the communication between the buffer unit 131 and the serial port transceiver module 132. When data transmission between the buffer unit 131 and the serial port transceiver module 132 is required, the synchronous switch unit 133 can be kept connected.

[0027] The above-mentioned multiple synchronous switch units 133 can be configured to be controlled by the same switch control component 134, or can be configured to be independently controlled. When synchronous control is required, it is sufficient as long as the multiple synchronous switch units 133 can be synchronously turned on or off. It is understandable that when multiple synchronous switch units 133 are configured to be controlled by the same control component, if it is necessary to adjust the output of a power channel module 110 separately, it is only necessary to keep the multiple synchronous switch units 133 in the on state.

[0028] See also Figure 2 As shown, Figure 2 1 is a flowchart of a multi-channel battery simulator control method provided by an embodiment of the present application. The multi-channel battery simulator control method is applied to the main control unit 120, including: Acquire multi-channel setting information, where the multi-channel setting information includes a battery simulation configuration parameter corresponding to at least one power channel module 110; Generate a corresponding output adjustment control frame according to each battery simulation configuration parameter; Adjust the working states of the synchronous switch units 133 corresponding to the multiple power channel modules 110 according to the multi-channel setting information, so as to transmit each output adjustment control frame to the corresponding serial port transceiver module 132; Among them, when the corresponding synchronous switch unit 133 is turned on, each serial port transceiver module 132 obtains an output adjustment control frame from the corresponding cache unit 131, and transmits the output adjustment control frame to the corresponding power channel module 110, so that the power channel module 110 completes the output adjustment according to the battery simulation configuration parameters in the adjustment control frame.

[0029] The multi-channel battery simulator control method in the embodiment of the present application is implemented based on the above-mentioned multi-channel battery simulator. The multi-channel battery simulator has been described in detail above and will not be repeated here.

[0030] The battery simulation configuration parameters in the above multi-channel setting information can be obtained by inputting a human-computer interaction unit set on the multi-channel battery simulator, or by obtaining an external terminal device that can be connected to the multi-channel battery simulator, such as a computer, a mobile smart terminal, etc.

[0031] The above battery simulation configuration parameters are determined by the test personnel according to the experimental requirements. After the test personnel determine, multi-channel setting information can be generated according to the battery simulation configuration parameters for transmission to the main control unit 120.

[0032] The multi-channel setting information includes at least one battery simulation configuration parameter. When synchronous control is required, it includes the battery simulation configuration parameter corresponding to each power channel module 110. When independent control is performed, it may include at least the battery simulation configuration parameter corresponding to only one power channel module 110.

[0033] The main control unit 120 and the plurality of cache units 131 are connected via a bus, such as a FSMC bus.

[0034] The multi-channel setting information includes at least one battery simulation configuration parameter corresponding to the power channel module 110. After receiving the multi-channel setting information, the main control unit 120 can generate a corresponding output adjustment control frame according to each battery simulation configuration parameter. For example, in a synchronous control scenario, the multi-channel setting information includes battery simulation configuration parameters corresponding to multiple power channel modules 110, so that an output adjustment control frame corresponding to each battery simulation configuration parameter can be generated.

[0035] The working state of the above-mentioned synchronous switch unit 133 can be flexibly adjusted according to whether synchronous control is required. For example, when synchronous control is not required, all synchronous switch units 133 can be directly kept closed. When synchronous control is required, the consistency of output adjustment control frame transmission is maintained by controlling the synchronous disconnection and connection of the synchronous switch unit 133.

[0036] The above-mentioned serial port transceiver module 132 and the cache unit 131 have half-duplex communication. When the downlink data occupies the communication channel, the uplink data cannot be used, and vice versa. Therefore, when it is necessary to send down the output adjustment control frame, it can be directly sent down, and when it is necessary to upload the channel feedback frame, it can be directly uploaded and fed back.

[0037] After receiving the output adjustment control frame, the serial port transceiver module 132 will transmit it to the power channel module 110. After receiving the output adjustment control frame, the power channel module 110 can parse the required battery simulation configuration parameters from the output adjustment control frame and complete the adjustment according to the battery simulation configuration parameters. At the same time, under the premise that the output adjustment control frame is correct, a channel response frame will also be generated and uploaded so that the main control unit 120 can determine that the output adjustment control frame is delivered correctly.

[0038] In addition, during the data transmission process of the serial port transceiver module 132, it is also possible to first determine whether there is data in the cache unit 131 that needs to be sent down, and first determine whether the main control module has data sent down to the cache unit 131, and then upload it when it is determined that there is no data sent down. The judgment method is also relatively simple, and the first count value can be directly set in the cache unit 131 to count the data of the received output adjustment control frame. As long as the first count value is not the initial value, for example, it is not 0, it can be explained that there is data sent down in the current cache unit 131, and data cannot be uploaded. Because the output adjustment control frame is generated according to a predetermined communication protocol, the data length of the output adjustment control frame, such as the number of bytes, can also be directly determined, that is, when the output adjustment control frame is sent down, the first count value in the cache unit 131, that is, the number of bytes cached, can also be determined, so that the data reading can be completed after the number of bytes counted by the first count value corresponds to the number of bytes of the adjustment control frame. After reading, the first count value can be counted back to the initial value.

[0039] In some embodiments, the multi-channel setting information further includes synchronization flag information, and the synchronization flag information is used to indicate whether the multiple power channel modules 110 are to be synchronously controlled; When the synchronization flag information indicates that the multiple power channel modules 110 need to be synchronized, the working states of the synchronization switch units 133 corresponding to the multiple power channel modules 110 are adjusted according to the multi-channel setting information to transmit each output adjustment control frame to the corresponding serial port transceiver module 132, including: Controlling the synchronous switch units 133 corresponding to the multiple power channel modules 110 to be disconnected; Transmitting the output adjustment control frames corresponding to the multiple power channel modules 110 to the corresponding cache units 131; When the output adjustment control frame corresponding to each power channel module 110 is transmitted to the corresponding buffer unit 131 , the plurality of synchronous switch units 133 are controlled to be closed to transmit the plurality of output adjustment control frames to the corresponding serial port transceiver module 132 .

[0040] The synchronization flag information allows the main control unit 120 to determine whether synchronization control is required. Specifically, after receiving the multi-channel setting information, the main control unit 120 needs to first determine the synchronization flag information therein so as to adjust the state of the synchronization switch unit 133 in time.

[0041] In this embodiment, when it is determined that synchronous control is required, the synchronous switch units 133 corresponding to the multiple power channel modules 110 that are to be synchronously controlled need to be disconnected first, so as to avoid the output adjustment control frame being directly read by the serial port transceiver unit after the main control unit 120 transmits it to the cache unit 131. After that, after waiting for the main control unit 120 to transmit all the output adjustment control frames to the corresponding cache unit 131, the multiple synchronous switch units 133 are controlled to be turned on. At this time, the multiple serial port transceiver modules 132 can obtain the corresponding output adjustment data frame from the corresponding cache unit 131 and forward it to the power channel module 110.

[0042] It should be noted that in a synchronous control scenario, when a new multi-channel setting information is received and it is determined that the synchronization identification information indicates that synchronization is required, the synchronous switch unit 133 needs to be disconnected first and then kept closed during the subsequent adjustment process.

[0043] In some implementations, when the corresponding synchronous switch unit 133 of each serial port transceiver module 132 is turned on, the serial port transceiver module 132 obtains the output adjustment control frame from the corresponding buffer unit 131 through the following steps, including: Reading a first count value in the corresponding cache unit 131, where the first count value is determined when the main control unit 120 transmits an output adjustment control frame to the cache unit 131, and is used to record the data size of the output adjustment control frame; The output adjustment control frame is read from the cache unit 131 according to the first count value, wherein the first count value is restored to an initial value when the output adjustment control frame is completely read.

[0044] The above-mentioned first count value can count the number of data bytes received by the cache unit 131, and the first count value can be read by the serial port transceiver module 132. When the cache unit 131 adopts a FIFO cache unit, the serial port transceiver module 132 only needs to use the first count value to directly read the data in the cache unit 131 without performing complex addressing operations.

[0045] The above-mentioned first count value can also be used for data frame detection. Considering that each output adjustment data frame is specified according to the same communication protocol and therefore has the same number of bytes, if it is determined during the data sending stage that the first count value is inconsistent with the number of bytes of the output adjustment data frame, it can also be preliminarily determined that the data transmission is erroneous.

[0046] After the serial port transceiver module 132 has finished reading the output adjustment data frame, the first count value will be restored to an initial value, which can usually be understood as being assigned a value of 0.

[0047] In some embodiments, the multi-channel battery simulator control method further includes: Acquire channel response frames in multiple cache units 131, each channel response frame is generated by the corresponding power channel module 110 after successfully parsing the output adjustment control frame, and is transmitted to the cache unit 131 via the serial port transceiver module 132; wherein each cache unit 131 accumulates and updates the second count value in the cache unit 131 when receiving the channel response frame; An alarm strategy is executed according to the plurality of second count values.

[0048] The channel response frame is generated after the power channel module 110 receives the output adjustment data frame and successfully parses it, and is used for feedback so that the main control unit 120 can determine whether the data has been successfully sent to the power channel module 110 .

[0049] The channel feedback frame is also counted during the process of being uploaded to the buffer unit 131 , and a second count value is determined.

[0050] The second count value is used to determine the number of bytes of the channel response data fed back by the power channel module 110 , so that the main control unit 120 can use the second count value to determine whether the power channel module 110 successfully obtains the battery simulation configuration parameters.

[0051] In some implementations, executing an alarm strategy according to a plurality of second count values ​​includes: When the second count value in any cache unit 131 is not updated, an alarm message is generated.

[0052] In this embodiment, considering that if the power channel module 110 does not receive the correct output adjustment data frame, it is impossible to obtain the battery simulation configuration parameters, and then it is impossible to generate a channel response frame, and no data will be fed back to the cache unit 131, so that the second count value cannot be accumulated and increased, so that it can be determined that a communication failure has occurred, and it is necessary to generate an alarm message and issue an alarm so that the staff can troubleshoot the problem in time.

[0053] In some embodiments, there are multiple multi-channel setting information; the multi-channel battery simulator control method further includes: In response to the stage test completion signal, the next-order multi-channel setting information is transmitted to the main control unit 120; The stage test completion signal is generated after the stage test is completed according to any multi-channel setting information.

[0054] In this embodiment, considering the continuity of the test in the actual project, there may be multiple multi-channel setting information that needs to be sent in one test. At this time, it is necessary to send multiple multi-channel setting information in sequence, and send the next multi-channel setting information after the test of the previous multi-channel setting information is completed. The test method in this embodiment can reduce the operator's operation workload to a certain extent, which is convenient for large-scale experiments and improves the detection efficiency.

[0055] The above-mentioned stage test completion signal is generated by the BMS system or other detection test terminal after the test corresponding to each multi-channel setting information is completed, and is fed back to the host computer or main control unit 120 connected to the main controller.

[0056] In some implementations, the power channel module 110 performs output adjustment by the following steps: In response to a DMA (Data Memory Access) data reception interrupt, a data reception terminal program is entered; Obtaining output adjustment control frames in the data receiving terminal program; Parse the output adjustment control frame, obtain the corresponding battery simulation configuration parameters, and generate a channel response frame; Complete output adjustment according to battery simulation configuration parameters; The channel response frame is transmitted to the serial port transceiver module 132 .

[0057] In this embodiment, data acquisition is performed by using DMA data receiving interrupts, which can greatly reduce the computing power occupied by the power channel module 110, and can also ensure the priority of receiving the output adjustment control frame. That is, it is only necessary for each power channel module 110 to set the priority of the DMA data receiving interrupt to the highest, which can effectively improve the synchronization of receiving the output adjustment control frame.
