Abstract


Aiming at the online monitoring of real-time operating of lithium-ion energy storage batteries for distributed power station, this paper studies the online monitoring system of lithium-ion energy storage batteries based on B/S network structure. The system consists of a battery status information collection unit, a centralized control unit, and a remote monitoring center. The battery status information collection unit detects the current, voltage, temperature and other parameters of the lithium ion energy storage battery in real time, transmits the data to the centralized control unit for data processing and real-time estimation of the SOC of the battery, and then the centralized control unit transmits the measurement parameters through the Internet network. The remote monitoring center monitors and analyzes the battery real-time status data, accurately calculates the battery SOC, realizes the online real-time monitoring of the lithium ion battery, prevents the lithium ion battery from overcharging, over-discharging, overheating, and promotes the safe and stable operation of the lithium-ion energy storage battery.
