This paper designs a kind of lithium battery management system for coal mine electric trackless rubber tyred vehicle based on chip STM32F105VCT7 as CPU. It focuses on the battery grouping mode, battery balancing strategy and the hardware and software design of the battery management system. The lithium battery management system uses LTC6811-1 chip to collect battery information, designs passive balance to maintain the battery, and uses RT thread real-time operating system to schedule the tasks in the lithium battery management system. Through the actual test application, the lithium battery management system designed in this paper can effectively monitor the battery voltage, temperature, current and other information, and complete the battery balance, charge and discharge control.
