Nebula Regenerative Battery Cell Cycle Test System

Nebula NEEFLCT series is a regenerative battery cycle test system with modular design to demands across all tiers of the battery value chain including research and development, pilot production, production testing, and quality control. The discharge lower limit voltage can be set to a negative value for a complete discharge test(±10V). It enables seamless high-current testing of battery cells within the broad current range of 100 amps to 3000 amps. Leveraging its regenerative power supply, a significant portion of the consumed energy is efficiently harnessed through the DC link or reintegrated into the grid, maximizing sustainability and cost efficiency.
