Functions

Functions

Fit more battery power into less space

Maximize use of available battery room space to achieve higher levels of battery system output and capacity with the Corvus Dolphin NxtGen ESS. The space efficient, rack-free design enables energy dense battery modules to be stacked in various configurations, like compact, high-energy building blocks. Eliminating the limitation of fixed-height racks provides the flexibility to fully utilize the space available and allows you to fit more battery power within a limited footprint.

  • Low C-rate for slow charge and discharge

  • Low weight

  • Designed for voltages up to 1200 VDC

  • Flexible installation

  • Low life cycle cost  

  • Easy and safe plug and play connections

  • Very flexible and modularized design

  • Passive Single-cell Thermal Runaway protection

  • Scalable capacity and voltage according to vessel requirements

  • Industry-proven Battery Management System (BMS)

  • Remote monitoring capabilities

  • Enhanced EMI immunity design for maritime environments

Next generation marine energy storage, advancing maritime battery technology with the Corvus Dolphin NxtGen ESS.

Leveraging the latest advances in marine battery energy storage technology and zero-emission solutions, the Dolphin NxtGen is the newest ESS in the Corvus Energy family of products. Its next generation design builds upon learnings from our experience with over 1,000 projects and millions of system operational hours as the maritime sector leader in battery energy storage and sets new industry standards in marine battery systems.
