Abstract: As an ideal energy storage carrier,lithium-ion batteries are widely used in various fields,especially to provide convenience for remote areas.However,lithium batteries have a service life,and their operating status is related to the stable operation of power supply equipment.So,real-time remote acquisition of status information has become an urgent problem.A battery status information collection system based on 4G wireless communication was proposed.Battery information collection is achieved through a single-chip computer and integrated chip,combined with 4G modules for remote transmission,and the remote reading of data is achieved by using Alibaba Cloud platform.The experimental results show that the designed system can realize the status information collection,wireless transmission and real-time display of 6 single-cell batteries.This system is beneficial to analyze the working status of the battery and facilitates regular maintenance by technicians.

Key words: lithium battery, battery state information acquisition system, hardware circuit, 4G wireless communication
