Liquid Cooling Battery Container System
Containerized Energy Storage System(CESS) or Containerized Battery Energy Storage System(CBESS)
The CBESS is a lithium iron phosphate (LiFePO4) chemistry-based battery enclosure with 5MWh of usable energy capacity, specifically engineered for safety and reliability for utility-scale applications. The CBESS is designed with liquid cooling and humidity control, active balancing battery management system (BMS) technologies, and complies with the latest international safety and compliance standards.
NEXTG POWER’s Containerized Energy Storage System is a complete, self-contained battery solution for a large-scale energy storage. The batteries and converters, transformer, controls, cooling and auxiliary equipment are pre-assembled in the self-contained unit for ‘plug and play’ use.
NEXTG POWER Energy Storage Systems (ESS), built on state-of-the-art-technology are modular solutions in terms of output power and energy. Variety of operation modes and flexibility to connect to any voltage level, makes NEXTG POWER ESS a preferred solution for complete electricity system value chain starting from the generation. Particularly renewable energy integration, and from Transmission and Distribution (T&D) down to hybrid, island and microgrids. Built-in flexible design permits easy scalability to deliver customized solution from few MWh to several hundred MWh. Typical operation modes of NEXTG POWER ESS include but not limited to are: frequency & voltage regulation, peak shaving and intermittent power support including unique power quality modes.
