Design and Implementation of Vanadium Flow Battery Management System
Vanadium flow battery is a new type of electrochemical energy sto rage battery.To ensure the safe operation of batteries,it is necessary to effectively manage them.Firstly,the working principle of all vanadium flow batteries was introduced,and an overall design scheme for the management system of all vanadium flow batteries was proposed.Secondly,the hardware selection scheme for the vanadium flow battery management system was introduced,and a PLC-based all vanadium flow battery management system was developed.The battery management system realizes functions such as real-time data collection,status monitoring,fault protection,SOC estimation,charge and discharge control,and mixing of batteries.Long term operation was conducted on a 10 kW vanadium flow battery energy storage system,verifying the feasibility and stability of the battery management system.
