Corvus Dolphin Power

The Dolphin Power ESS is specifically designed for lightweight applications. Dolphin Power combines outstanding power density and a reasonable energy density with the highest level of safety, setting a new industry standard for maritime energy storage systems.

The flexible design of the Dolphin Power allows the system to be stacked in various directions enabling high space efficiency in compact installations. Dolphin Power is ideal for high-speed vessels that need to boost propulsion to
reach max speed, or vessels that must recharge the batteries quickly and often.

Applications

Dolphin Power is ideal for vessels where light weight is essential but where high charge or discharge power is also required. Typical vessels are:

  • Fast ferries
  • Ferries
  • Yachts
  • Tourist vessels
  • Cruise ships
  • Sightseeing vessels

Features

  • High C-Rate, up to 4,4C peak
  • Low weight
  • Designed for voltages up to 1000 VDC
  • Flexible installation
  • Low life cycle cost  
  • Easy and safe plug and play connections
  • Very flexible and modularised design
  • Passive single-cell Thermal Runaway protection
  • Reduces fuel, emissions, noise and maintenance
  • Industry-proven Battery Management System (BMS)
  • Remote monitoring

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 dependent on active cooling
