The Nebula 1650V PACK Cycle Test System is a high-power battery testing solution designed for next-generation high-voltage energy storage batteries and battery PACKs.
Built on a full-SiC power architecture and LLC high-frequency isolated soft-switching technology, the system combines high voltage capability, high power density, fast dynamic response, and intelligent power circulation. With Nebula’s intelligent power-circulation (energy-sharing) technology, up to 4 MW of battery testing power can be supported with a conventional 380 V power supply, significantly reducing the need for facility power expansion.
Designed for evolving energy storage technologies, the 1650V PACK Cycle Test System provides a scalable platform for battery R&D, validation, production testing, and high-power energy storage applications.
1650V High-Voltage Platform
Designed for the Next Generation of Energy Storage Batteries
As battery system voltages continue to increase, higher-voltage testing platforms are becoming essential for energy storage battery development and validation.
The Nebula 1650V platform supports:
- Charge voltage: 0–1650 V
- Discharge voltage: 50–1650 V
- Single-unit power: Up to 1.5 MW
- System power: Up to 4 MW with intelligent power circulation
The high-voltage architecture enables comprehensive testing of high-voltage battery PACKs while providing the headroom required for next-generation energy storage systems.
Full-SiC High-Frequency Architecture
More Power in a Smaller Footprint
The system adopts full-SiC power devices together with LLC high-frequency isolated soft-switching technology to achieve high power density and efficient energy conversion.
With a compact integrated design, a single unit weighs approximately 2 tons and occupies only 2.52 m², delivering a power density of up to 595.24 kW/m².
This compact architecture helps optimize factory space utilization while simplifying equipment deployment and expansion.
Intelligent Power Circulation
MW-Level Testing Without Major Grid Expansion
High-power battery testing does not always require a high-capacity utility connection.
Nebula’s intelligent power-circulation technology enables energy to be exchanged between charge and discharge channels, allowing energy to be reused within the testing system.
As a result, the system can support up to 4 MW of battery testing power using a conventional 380 V facility power supply, helping manufacturers:
- Reduce or avoid facility power expansion
- Minimize electrical infrastructure investment
- Deploy high-power testing in existing facilities
- Reduce long-term energy consumption
- Accelerate testing capacity expansion
This makes the system particularly suitable for existing battery factories and facilities with limited grid capacity.
