CORUN provides highly integrated energy storage system solutions based on lithium iron phosphate battery and nickel-metal hydride battery energy storage technologies. The Hybrid Storage and Smart Energy System was innovated and developed by the National Engineering Research & Test Center for Advanced Energy Storage Materials, paired with the 3S Smart Energy Management System, integrates electrochemistry, computational science, and digital twin technology to establish a real-time simulation platform for the full life cycle of batteries. This platform enables early prediction, identification, and diagnosis of potential risks in ultra-large energy storage systems, enhancing the overall energy storage performance and achieving an “optimal integrated management solution”. The system dynamically manages the timing and depth of intervention of the nickel-metal hydride lithium battery and lithium battery combination during the charging and discharging, ensuring optimal response variable power fluctuations on the power supply side. This hybrid storage combination operates under peak performance, improving the safety of the energy storage system and reducing the cost of the overall life cycle.
