[0030] (Example 1)
[0031] see Figure 1 to Figure 6 , The present invention has a cabinet; outside the cabinet is connected to the SWD download interface P3 of the embedded microcontroller U1 with the chip model STM32F103VET6, the sampling interface P10, the drive interfaces P11, P12, P13 and P14, and the serial screen interface P6, RS232 test interface P5, host computer communication interface P7 and CAN communication interface P8. The box is equipped with a control circuit board, four PWM drive circuit boards and four mosfet circuit branches 1 through fasteners; each mosfet circuit branch 1 Each includes a mosfet with anti-series and internal anti-parallel diodes. The PWM drive circuit board drives each branch mosfet circuit branch 1 through the drive interfaces P11, P12, P13 and P14, and the mosfet drain is connected to the four batteries through the output terminal. The output terminals of every two mosfet circuit branches 1 are connected to form an output terminal, and th...
