Referring to fig. 1 and 2, the BMS software testing System 10 includes a Battery Management System (BMS) controller 101 and an upper computer 102. The battery management system controller 101 is connected with the upper computer 102 through a communication connection device (not shown in the figure). The communication connection device may be a communication device with different communication formats, such as a Controller Area Network (CAN), a Universal Asynchronous Receiver/Transmitter (UART), RS-485, and Ethernet (Ethernet).
In the present embodiment, the battery management system controller 101 includes a Micro Controller Unit (MCU) 103 and an external device 104. A battery management system 1030 may be run in the micro control unit 103, where the battery management system 1030 includes an application layer 1031, a communication interface layer 1032, and a driver layer 1033.
In this embodiment, the application layer 1031 is used to implement various functions of the battery management system 1030. Such as charging, discharging, and power consumption management.
The communication interface layer 1032 isolates the application layer 1031 from the driver layer 1033, so as to ensure that the application layer 1031 does not directly call the driver layer 1033, and the communication interface layer 1032 provides a communication interface for the upper computer 102, and simultaneously encapsulates the functions and interfaces of the driver layer 1033 for use by the application layer 1031.
The driver layer 1033 provides hardware function drivers for the battery management system 1030. For example, hardware function drivers such as sampling, clock, interrupt, communication, storage, IO, etc. are provided for the battery management system 1030.
The upper computer 102 can perform function testing and software monitoring on the battery management system 1030. The upper computer 102 can be installed on a PC (personal computer) or an industrial touch screen (HMI) and other devices. When the battery management system controller 101 needs to be remotely accessed and controlled through the upper computer 102, the upper computer can also be installed in a webpage on a server. The upper computer 102 can monitor the running state of the battery management system 1030 and can also edit a test case so as to test the software function of the battery management system 1030.
In this embodiment, in order to facilitate testing of software functions of the battery management system 1030, the battery management system 1030 includes two operation modes: a normal mode and a test mode.
In response to the battery management system 1030 operating in the normal mode, the application layer 1031 obtains sampling information and state information from the driver layer 1033 through the communication interface layer 1032, and performs a charging and discharging process according to the sampling information and the state information. In this embodiment, the sampling information includes voltage, current, temperature, IO, and the like. The state information balances state, running state and fault state. The BMS software testing system 10 is communicatively connected to an external device 20 as shown in fig. 3. For example, the external device 20 is electrically connected to the driving circuit in the external device 104. The BMS software testing system 10 may also be electrically connected to the battery 11.
Specifically, in response to the battery management system 1030 operating in the normal mode, the application layer 1031 obtains the required sampling information and status information from the driver layer 1033 through the interface provided by the communication interface layer 1032. Meanwhile, the external device is driven by the driving layer 1033 to acquire the sampling information and the state information, and a charging and discharging process is executed according to the sampling information and the state information to test the BMS software. For example, the communication interface layer 1032 calls a driving interface of the bottom layer, and obtains an external sampling signal during the battery operation through an AFE (analog front end) and a sampling circuit. And converting the external sampling information through the sampling circuit to obtain an actual parameter value in the working process of the battery, and updating the parameter value to a corresponding interface. The application layer 1031 may obtain the real external information (such as the parameter value) by calling the communication interface layer 1032. Meanwhile, the application layer 1031 may also determine the state of the BMS according to the obtained external information, determine the state of the external device according to a predetermined policy, and then call the communication interface layer 1032 to control the external device, thereby implementing the control of the BMS on/off of the battery 11.
Responding to the battery management system 1030 working in a test mode, the upper computer 102 sends simulation sampling information and simulation state information to the battery management system 1030, the upper computer 102 receives input test parameters, and simulates a battery charging and discharging process according to the parameters, the simulation sampling information and the simulation state information to obtain a test result. The test parameters include a start parameter, an end parameter, a step size of parameter change, an expected result, and an expected execution time. The upper computer 102 also compares the test result with the expected result, and when the test result is consistent with the expected result, the test is confirmed to pass; confirming a test failure when the test result is inconsistent with the expected result.
Specifically, in response to the battery management system 1030 operating in a test mode. The application layer 1031 obtains the required sampling signal and status signal from the upper computer 102 through the interface provided by the communication interface layer 1032, and performs a test according to the sampling signal and status signal. The sampling signal and the state signal are obtained from the external equipment for testing (such as a charging simulation device) without waiting for the connection of the external equipment. The effects of lower cost and higher test efficiency can be achieved.
In response to the battery management system 1030 operating in a test mode. The driver layer 1033 continues to operate normally, the communication interface layer 1032 does not acquire sampling information of the driver layer and does not calculate actual parameter values, the communication interface layer 1032 acquires simulation data sent by the upper computer 102 and updates the simulation data to a corresponding interface, and the application layer 1031 can acquire the corresponding simulation data through the communication interface layer 1032. Because the simulation data is selected according to the actual operation condition of the battery management system 1030, the upper computer 102 can simulate the actual operation environment of the software of the battery management system 1030 by issuing different simulation data.
In this embodiment, the communication interface layer 1032 provides a device control interface to the application layer 1031, and the application layer 1031 calls the device control interface, so that the battery management system 1030 may further send a control command to an external device. Meanwhile, a control command that the BMS transmits to the external device is transmitted to the upper computer 102 through the driving layer 1033, so that the operation state and the control command of the battery management system 1030 can be confirmed.
When the upper computer 102 tests the functions of the battery management system 1030, the battery management system 1030 works in a test mode. The upper computer 102 is connected with the battery management system controller 101 by using a communication connection device, and sends the analog sampling information and the analog state information to the battery management system 1030 according to an agreed protocol. The protocol may be a standard CAN protocol, a UART protocol, an RS-485 protocol, and a TCP/IP protocol, depending on the external communication hardware of the battery management system controller 101. The upper computer 102 may display simulation data acquired by the application layer 1031 of the battery management system 1030, and also support setting of different test cases according to actual operating conditions of the battery management system 1030. The upper computer 102 also supports the design of test cases according to requirements, and the test cases can be used for testing voltage, temperature and current related abnormity and testing the current limiting and balancing functions of the BMS.
For example, in testing voltage, temperature and current related anomalies, the tester is allowed to enter a start parameter, an end parameter, a step size of parameter changes, expected results, and expected action time. When the input is completed and the test is started, the upper computer 102 starts timing, increases the step length of the parameter change on the initial parameter at regular time, and then sends the parameter to the battery management system 1030. After the expected action time is reached, the test result is obtained. Comparing the test result with the expected result. When the test result is consistent with the expected result, the test meets the expected result, and the test is confirmed to pass; and when the test result is inconsistent with the expected result, the test does not meet the expected result, and the test is confirmed to fail.
In the present embodiment, the normal mode and the test mode of the battery management system 1030 are also switched by:
first, in order to prevent the battery management system 1030 from abnormally switching between the normal mode and the test mode, the test mode is reserved only in the software development stage. When the battery management system 1030 is completely developed, the function of switching between the normal mode and the test mode needs to be deleted in software, and only the normal mode needs to be reserved.
In the second mode, the operation mode flag is stored in a memory (e.g., a nonvolatile memory) for switching convenience and ensuring that no switching abnormality occurs. For example, the run mode flag is stored in a macro-defined form or written into a FLASH space of the code, and cannot be modified. Specifically, when the battery management system 1030 needs to operate in the normal mode, the operation mode flag is set to be in the normal mode, and the set operation mode flag is burned into the battery management system 1030. As such, the battery management system 1030 will always operate in the normal mode. When the battery management system needs to operate in the test mode, the operation mode flag is set as the test mode, and the set operation mode flag is burned into the battery management system 1030. As such, the battery management system 1030 will always operate in the test mode.
And secondly, storing the operation mode mark in an external memory (EEPROM) or an internal memory (Flash) and allowing the upper computer to modify the operation mode mark. And developers can conveniently select the working mode according to the actual situation. Specifically, the operation mode flag is stored in a memory, when the battery management system 1030 needs to operate in a normal mode, the mode flag in the memory is modified to the normal mode by the upper computer, and the battery management system 1030 operates in the normal mode; when the battery management system 1030 needs to operate in a test mode, the mode mark in the memory is modified into the test mode through the upper computer, and the battery management system 1030 operates in the test mode.
