Flow Battery
Product Overview:
LCX Power-DTL redox flow battery series includes all-vanadium, iron-chromium and zinc-bromine types.
Energy is stored in liquid electrolyte instead of solid electrode materials.
The whole system consists of electric stack, electrolyte storage tanks, circulating pipeline, thermal management and intelligent EMS control unit.
Power and energy capacity can be designed independently, and longer discharge duration can be realized by expanding the volume of electrolyte tank.
Different electrolyte systems meet diversified project requirements.
The electrolyte has good chemical stability, low capacity attenuation and excellent safety performance.
Modular and containerized design is available, which can be matched with PCS and energy management system.
It is an ideal long-duration energy storage solution for large-scale new energy power stations, microgrids and industrial backup power supply.
Typical Applications:
· Long-duration energy storage for wind & solar power stations to smooth power fluctuation and peak shaving
· Grid side peak and frequency regulation to improve new energy consumption capacity
· Independent energy storage power supply for island microgrid, mining area and industrial park
· Long-time backup power for large data centers and critical industrial facilities
· Large-scale off-grid energy storage projects for water conservancy, oil & gas and remote islands
· Municipal emergency energy storage and supporting power for grid black start
Technical Specifications:
1. System & Structural Design Redox flow battery architecture, power stack and energy storage electrolyte tank are separated. Power and capacity support independent capacity expansion. Optional all-vanadium / iron-chromium / zinc-bromine electrolyte system to adapt different budget and application demands. Modular container integration, convenient transportation and field installation. Full digital EMS realizes coordinated control of pump, heat exchange and battery stack.
2. Electrical Performance
