Summarize
Li-ion battery system mainly consists of battery, power conversion system (PCS), energy management system (EMS), battery management system (BMS) and other electrical equipment. The secondary BMS is designed with multiple monitoring of system status and hierarchical linkage. Relays, fuses, circuit breakers, BMS constitute a comprehensive protection system integrating electrical and functional safety.
System Components
Lithium Battery Module
The system is mainly composed of a safe, efficient and long-life lithium iron phosphate cell through seriesand parallel to form a battery module, several modules in series to form a battery cluster.
Battery Management System
The core component of the system effectively protects the battery from over-charging, over-discharging, over-current, etc., and at the same time manages the equalization of the battery cells to guarantee the safe, reliable and efficient operation of the whole system.
Monitoring System
System operation data monitoring, operation strategy management, historical data logging, system status logging, etc.
System Features
safe And Reliable
First-line manufacturer cells, intelligent air-cooling design, long life. Module, battery cluster secondary BMS design, multiple status monitoring, three-level electrical protection system.
Efficient And Convenient
High-energy type system has high energy density, stable and reliable performance, long service life, and modularized design, which is convenient for maintenance, management, and capacity expansion.
Active Equilibrium
3A active equalization to overcome the influence of single cell capacitance on system capacity. Equalization accuracy is less than 2%, and equalization capacity reaches 10% of rated output.
Cost Optimization
Small size and light weight, saving space and costs. Long cycle life, low failure rate, reduce 0&M investment.
Electric Core
Lithium battery system using 3.2V 280Ah high energy type lithium iron phosphate core, square aluminum shell design, reduces the possibility of damage to the surface of the core due to mechanical damage and of damage to the inside of the core, improves the safety performance of the product. The battery cells are installed with a film-shaped explosion-proof valve to ensure that in any extreme case (such as internal short circuit, battery overcharge and overdischarge, etc.), a large amount of gas quickly gathered inside the battery cell can be discharged through the explosion-proof valve to improve safety.
Module
The battery module consists of 12 3.2V 280Ah lithium iron phosphate cell, 1 parallel and 12 strings (12S1P) to form a 38.4V 280Ah battery module. The module has a built-in BMU system, which collects the voltage and temperature of each cell and manages the equalization of cells to ensure the normal operation of the whole module safely and efficiently.
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 energy storage cabinets really need?
100kWh-215kWh indoor energy storage cabinets are installed in a footprint of 4m' Weight of about 2.5T, three-sided side-by-side design covers a small area. Outdoor cabinets are designed in accordance with fire protection and temperature control requirements and can be placed in the open space outside the distribution room as per.
