  • Ecapsulation in cylindrical units
  • Designed for pack voltages up to 900 VDC
  • Scalable up to 4 MWh  
  • Supports currents up to 50A max per pack
  • Low life cycle cost
  • High Safety
  • Reduces fuel, emissions, noise and maintenance
  • Industry-proven Battery Management System (BMS)
  • Remote monitoring
  • Very low self discharge and sleep mode option for long term energy storage

Orca safety innovations

Cell-level Thermal Runaway (TR) Isolation

  • True cell-level thermal runaway isolation – TR does not propagate to neighbouring cells
  • Isolation NOT dependant on active cooling

Exceeds Class and Flag standards TR Gas venting

  • Integrated thermal runaway gas exhaust system
  • Easily vented to external atmosphere rather than the battery room

Additional fire suppression system not required.
