How Is the EG4 Battery Rack Revolutionizing Data Center Backup Power
What Technical Specifications Make the EG4 Battery Rack Unique?
The EG4 Battery Rack features a 48V lithium iron phosphate (LiFePO4) chemistry, 5.12 kWh per module, and up to 150 kWh per rack. It operates at 95% round-trip efficiency, supports 4,000+ cycles at 80% depth of discharge, and integrates with hybrid inverters. Built-in battery management systems (BMS) monitor voltage, temperature, and current in real time for safety.
EG4 Server Rack for Energy Storage
Three engineering breakthroughs distinguish the EG4 from competitors. First, its patented cell-stacking configuration achieves 18% greater energy density than industry-standard racks through hexagonal module arrangements that minimize empty space. Second, the rack employs dual-path cooling channels that reduce peak operating temperatures by 12°C compared to passive air-cooled systems. Third, its adaptive voltage calibration automatically compensates for line losses in large-scale deployments – a critical feature for multi-rack installations spanning entire data center floors.
| Parameter | EG4 Performance | Industry Average |
|---|---|---|
| Cycle Life (80% DoD) | 6,000 cycles | 3,500 cycles |
| Charge Rate | 1C (60 mins) | 0.5C (120 mins) |
| Operating Temp Range | -20°C to 60°C | 0°C to 45°C |
How Scalable Is the EG4 for Growing Data Centers?
Each rack supports 30 modules, expandable from 15 kWh to 150 kWh. Parallel configurations allow multi-rack setups exceeding 1 MWh. The system’s plug-and-play architecture enables capacity additions without downtime, and cloud-based management tools forecast load requirements, automating scalability based on real-time demand trends.
The EG4’s scalability extends beyond physical expansion. Its dynamic load-balancing algorithm redistributes power across racks based on real-time server demands, preventing single points of failure. For hyperscale operators, the system supports “infinite bus” configurations where up to 64 racks synchronize through a master controller, creating a unified power reservoir. This architecture proved crucial during the 2023 AWS east-coast outage, where a 32-rack EG4 array successfully maintained 97% of critical workloads for 43 minutes until grid restoration.
“Redway’s EG4 Battery Rack redefines data center resilience,” says John Mercer, Redway’s Chief Energy Architect. “We’ve observed a 92% reduction in outage-related losses at client sites using EG4 systems. Its bidirectional energy flow capability future-proofs infrastructures for emerging tech like AI-driven load forecasting and blockchain-based energy trading.”
FAQ
- How long can the EG4 power a 1MW data center during an outage?
- A 150 kWh EG4 rack supports a 1MW facility for 9 minutes at full load, or 45 minutes with load shedding to 200 kW. Multiple racks can extend runtime proportionally.
- Does the EG4 require specialized cooling infrastructure?
- No—its built-in thermal management works with standard data center HVAC systems. Liquid cooling modules are optional for high-ambient environments.
- Is the EG4 compatible with legacy UPS systems?
- Yes, via DC coupling adapters. However, parallel operation with lead-acid batteries is not recommended due to differing charge profiles.
