Abstract: To satisfy the requirements of increasing function of vehicle-mounted module of BMS, and enhance the human-computer interaction experience, a vehicle-mounted module of BMS is designed and implemented. The MK60DN512ZVLQ10 is used as the MCU, and serial port HMI touch screen is used to display the data that come from battery control unit module. The interface of battery cell, battery pack, failure diagnosing and alarm is designed. Also, the charge/discharge management and system threshold of battery is set by using the touch screen. The CAN-bus data transmission protocol is designed and used in the data exchange between the MCU and the battery control unit module. Through the actual test of the charging and discharging process, the designed module has superior human-computer interaction function and stable property, so it may have good application prospects.
