Corvus Energy 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.
