Abstract: By analyzing the functional requirements of the light-duty lithium electric vehicle motor controller and battery management system, a motor-battery integrated controller was designed. STM32 was used as the central control module to realize motor drive, real-time perception and processing of controller current, voltage, temperature and other parameters, overcurrent, voltage regulation functions. The experimental results show that the voltage regulating module can provide stable power supply for each module, drive and control the three-phase motor to achieve efficient speed response, and accurately measure the temperature, voltage, current, speed and other parameters. The performance of the controller is stable. The design of the integrated controller reduces the number of electronic components, and reduces the bill of
materials cost of the light-duty lithium electric vehicle controller.
