0.5MWH power station storage system is one energy storage subsystem of 500kWh，this subsystem consists of one 100kW energy storage bidirectional converter and power control system(PCS）、battery manage system(BMS）、background monitoring and management system and Lithium Iron Phosphate battery modules. The entire energy storage system consists of a monitoring and management system to control and coordinate the work of the various components of the network. Lithium iron phosphate module is composed of a cluster by 216 F100 battery module through a series-parallel, then combined together by eight clusters in parallel. Power station energy storage system using scientific internal structure design, advanced battery production technology, and configure more advanced battery management systems and energy conversion systems with high energy and long life, safe and reliable, wide temperature range and other characteristics, is wind, photovoltaic energy storage, smart grid energy storage and other industries ideal green power products.
