【Abstract】 The hardware test platform for the battery management chip is designed. The hardware circuit modules of the hardware test platform are designed according to the functions of the chip to be tested, multiple working modes and modular design ideas. The system board development and test verification are completed. In order to ensure the functional integrity of the test platform, the hardware test platform is divided into three parts, monitoring function test circuit module, general function test circuit module, control and protection function test circuit module, which correspond to the three key functions of monitoring, protection and control of the chip. According to the type of communication interface through the I~2C interface reserved by the chip, the I~2C bus is adopted to implement the communication between the test board and the communication module. The communication module adopts the STM32 development board as the core processor, which solves the problem of data communication through a large number of I/O interfaces and provides the possibility of chip parallel testing. To realize the control of the test system platform by the upper computer, the specific test work is completed by transferring the test vector and test data through the PC interface. PCB board is produced according to the design. By comparing the data obtained from the upper computer test and hardware test equipment measured data, the functional testing of the hardware test platform is complete.更多还原
