The energy storage system installation is based on standardized containers. According to the capacity configuration requirements of the system, a 40-foot standard container is selected, and the 1.6MWh in kwh solar energy battery storage, PCS, AC and DC power distribution cabinet, local monitoring system, environmental control system, and fire protection system function modules are all centrally installed in the container, please refer to the following table for container parameters and internal system configuration:
No. | Item | Specifications |
1 | Total weight of the container system | <35 tons |
2 | Three-dimensional dimensions (W*D*H ㎜) | 40-foot standard container |
3 | Protection class | IP54 |
4 | Refrigeration method | air (air conditioner + air Road) |
5 | The air conditioner | installed on the container escape door |
6 | insulation | layer silica rock sandwich panel, fire resistance class A, with waterproof function,6 sides of heat preservation, ceiling and side wall thickness of 50mm, floor filled with rock wool thickness of 100mm |
7 | Lighting system | LED energy-saving lamps + lighting power supply lines |
8 | Fire detection system | smoke detection, heptafluoropropane fire extinguishing system, etc. |
9 | Grounding protection and other | energy storage container AC is TN-S power supply system, working zero line N and special protection line PE are strictly separated |
10 | Monitoring system | PLC, switch, etc. |
The energy storage battery of this project uses lithium iron phosphate portable power station, which has the advantages of stable charging and discharging performance, long service life, clean and environmental protection, and can save energy to the greatest extent.
The storage medium of the energy storage system is a lithium ion iron phosphate battery with high safety and high cycle life, which has the characteristics of modularization and easy installation and maintenance.
The single aluminum shell is 3.2V/280Ah, and the laser spot welding technology is used to form the PACK.
The battery pack box is 1P16S, and the parameters are 51.2V/280Ah (14.336kWh). The series of 14 battery modules is 1 cluster, and the energy is 51.2V. *280Ah*14=200kWh, 8 clusters merge into a set of combiner cabinets.
