The present invention discloses a battery state monitoring system of a wind power variable pitch system. The system comprises upper computer battery packs, the battery packs are connected with corresponding data collection circuits, and each data collection circuit performs data transmission with an upper computer through each respective AD conversion module; the upper computer can send chip selection signals to the enabling terminal of each AD conversion module, and each AD conversion module can generate enabling signals after receiving the chip selection signals to send the data collected bythe corresponding data collection circuits to the upper computer; each data collection circuit comprises one temperature collection circuit and one voltage sampling circuit; and the battery packs supply power to the AD conversion modules and the temperature collection circuits in the data collection circuits through a power supply management chip. In the prior art, the problems are solved that the structure of a battery
