Corvus Dolphin Energy

The Dolphin ESS from Corvus Energy is specifically designed for lightweight applications.

Outstanding energy density and power density combined with the highest level of safety has set the new industry standard.

Applications

Corvus Dolphin Energy is tailored towards ships with long, slow charges and discharges and where lightweight is essential; Tourist, sightseeing and canal boats which sail at slow to moderate speeds are ideal use cases for Dolphin Energy.

Corvus Energy safety innovations

Passive-Single-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.
