Centralized large-scale energy storage systems


The centralized large-scale energy storage system is highly integrated with lithium batteries, battery management systems, grounding systems, distribution systems, temperature control systems, and fire protection systems, with a rated DC voltage of 1305.6VDC. It can provide peak shaving and valley filling, grid frequency regulation, power expansion, and backup power services, helping customers reduce electricity costs to the greatest extent possible. It can be applied in scenarios such as primary and secondary frequency regulation on the power generation side, new energy matching, independent energy storage power stations, grid side energy storage power stations, medium and large industrial and commercial user sides, photovoltaic storage and charging matching, and super fast charging station matching.
