Description
Lithium battery energy storage cabinet（Energy）
Lithium battery system is mainly composed of battery, energy storage inverter(PCS), energy,management system (EMS), battery management,system (BMS) and other electrical equipment. Secondary BMS design, multiple monitoring of system status, hierarchical linkage. Relays, fuses, circuit breakers, and BMS constitute a comprehensive protection system integrating electrical safety and functional safety.
FAQ
How is the early warning of the security system realized? BMS three levels, a first level of warning, the second level of alarm power reduction, three levels of power outages; temperature, smoke, combustible gas detection, the use of propane fire extinguishing, there are remote and on-site alarms, far infrared video monitoring and recording and other ways. How is ultra-high voltage converted to supply voltage? Inside the enterprise, the ultra-high voltage of the utility power is converted into supply voltage by means of a substation or transformer to supply normal equipment use and energy storage setups. Warranty issues, cycle count issues, how many cycles is a normal battery? Warranty 5 years, the first three years free of charge, the next two years to charge the cost of accessories, travel costs; the normal cycle life of the battery in 6000 The normal cycle life of the battery is more than 6000 times, 1 charging and 1 discharging per day can be used for more than 15 years, 2 charging and 2 discharging can be used for more than 8 years. How do you maximize the efficiency of 2 charging and 2 discharging? Valley-peak, flat-peak (full charge and discharge) This maximizes system utilization. What are the configuration facilities of the storage cabinets? It consists of battery pack, battery management system BMS, energy storage converter PCS, energy management system EMS, fire protection system, monitoring system and other related auxiliary systems. system, monitoring system and other related auxiliary systems, small size, large storage capacity, high temperature and low temperature resistance. What are the benefits of energy storage cabinets? (1) Shaving peaks and filling valleys, saving more than 60% of electricity costs by utilizing the peak and valley price difference. (2) Not troubled by power outages, pulling the power limit, not affecting normal production. (3) State subsidies, equipment credit for corporate income tax. (4) Emergency disaster preparedness standby. (5) Reduce carbon emissions, grid-connected operation, all benefits, data open and transparent, national grid monitoring and accounting. (6) Lithium iron phosphate battery will not trigger its own thermal runaway, no explosion, no fire. How big of a footprint do you really need for an energy storage locker, how big is 20 feet how big is 40 feet? (1) The size of 20-foot container is: 6.058*2.438*2591 meters; 40-foot container size is: 12.192*2.438*2591 meters (1.5-2 meters position is reserved around the box for maintenance). (2) 100kW-215kwh distributed energy storage cabinet indoor installation footprint in 3m weight of about 2.5T, three-sided side-by-side design covers a small area. The cabinet is designed according to the requirements of outdoor cabinet, and can be placed in the open space outside the power distribution room. Annual maintenance fee for the storage locker? Roughly, for every 1 MWh, the maintenance fee is about 10,000 yuan, the maintenance fee is less in the first 3 to 5 years, and the maintenance fee after five years is about 0.5-2% of the cost of the whole set of equipment; (investing in a 1 WKH energy storage cabinet, the investment cost is about 1,450,000 yuan, and the maintenance fee after five years is about 7,000 yuan to 28,000 yuan, depending on the degree of aging on the site)
