With the continuous improvement on mine equipment automation level and the progress of battery manufacturing technology, Lithium-ion batteries are widely used in mining transportation, monitoring communication and emergency facilities. This paper designs a kind of lithium-ion battery management system for explosion-proof mining electric vehicle according to GB3836-20210 series standard. And the management system takes STM32F103 as the main controller and LTC6811 as the core, using passive equalization strategy to realize battery voltage equalization. The test results show that the maximum error of 100 batteries after equalization is 0.32v, the average error is 0.03v and the maximum error between the monitoring value and the measured value is 0.3v, the average error is 0.0019v, which prove that the management system has high accuracy and effectiveness.
