The lithium iron phosphate battery, battery management system, energy storage converter, monitoring module, power distribution module, fire protection and temperature control module are highly integrated into a standardized outdoor cabinet, which has the advantages of high integration and low floor area, and can realize the functions of peak-load shifting, demand management, demand-side response, PV-storage-charging linkage, etc.
Distributed Energy Storage System Solution for Outdoor Cabinets
Overview
Features
Discharge capacity: regularly conduct SOC automatic calibration; One cluster and one management, avoid parallel mismatch, and increase the discharge capacity in the whole life cycle by about 10%
Intelligent temperature control: With intelligent temperature control function, the internal temperature rise is less than 5℃, 0.5C, and the service life of the battery is increased by 10% based on the container scheme
Equipment investment: the cost is reduced by up to 35%
Floor area: Compact layout, higher degree of integration, saving about 50% ~ 80% of the floor area
Modular system design: PCS is of modular design, and the failure of a single PCS or a single battery cluster does not affect the availability of other battery clusters, and the system availability can reach 99%
Safety performance: change the large-scale centralized mode to outdoor cabinet, which reduces the fault loss caused by fire safety by more than 90% and avoids the risk of fire spread
Convenience: with prefabricated installation, the wiring and commissioning of on-site installation is avoided; change power plant construction into plant installation, which reduces the design cost by 50% and installation and commissioning cost by 60%
System efficiency: No isolation transformer, improve the daily combined efficiency by 2%; Three-level high-performance energy storage converter improves daily combined efficiency by 0.9%; Distributed air conditioning layout, the temperature difference is reduced by 2~5℃, the consistency is improved by 10%, the daily combined efficiency is improved by 1.14%, and the daily combined efficiency is improved by about 4.04%
