Overview, Design Philosophy and Specifications - 5MWh Battery Container
Large-scale battery energy storage systems (BESS) stabilize renewable power by capturing surplus generation and delivering it when demand rises. Elektra’s utility-scale solutions integrate advanced lithium-ion battery technology with liquid cooling, fire suppression, and intelligent monitoring systems to ensure safe, reliable operation.
Proven in diverse applications, these systems enhance grid resilience, efficiency, and the overall reliability of renewable energy supply.
The Energy Storage System (ESS) adopts a modular architecture with a clear hierarchy of battery cells, modules, clusters, and fully integrated containerized systems. Each container is equipped with:
- Battery racks with advanced Battery Management System (BMS)
- Precision liquid-cooling thermal management system
- Integrated lighting system
- Fire detection and automatic suppression system
- Security and access control system
- Emergency response and protection mechanisms
This design ensures scalability, safety, and operational reliability for utility-scale energy storage applications.
