In order to further strengthen the monitoring of university electric bicycle charging process and facilitate electric bicycle users and battery researchers to obtain charging data, an electric bicycle charging process monitoring system based on the IoT was designed. The system mainly relies on Zigbee module for local networking. STM32 issues control commands to each IM1281B module through the network to collect and aggregate charging data of multiple electric bicycles. The summarized data is uploaded to the cloud server through the WiFi module, and the WeChat mini program obtains real-time information of the cloud server to realize user interaction. Open data sites store long-term charging data and provide battery researchers with a wealth of data. The experimental results show that the networking range of ZigBee module is 150 m, which meets the networking distance requirements of electric bicycle charging points in universities. The charging data collected is calibrated by standard electrician digital clamp meter VC866A, and the relative error is less than 3%. The system successfully realizes the collection, transmission, storage and display of charging data of multiple electric bicycles.
