Bluefin 1.5 kWh Subsea Battery
The Bluefin 1.5 kWh Subsea Battery is a pressure-tolerant lithium-polymer battery that provides a reliable, high-energy density power solution for underwater systems. The battery electronics include built-in protection, monitoring, power control, and battery conditioning. Leveraging over a decade of battery development and with hundreds of units in the field, the 1.5 kWh Subsea Battery has demonstrated utility across a variety of underwater applications, including:
- Autonomous Underwater Vehicles (AUVs)
- Remotely Operated Vehicles (ROVs)
- Submersible Systems
General Dynamics acquired Bluefin Robotics in February 2016.
The 1.5 kWh Subsea Battery is designed for direct submergence in water in any orientation, eliminating the need for a pressure vessel.
HIGH ENERGY DENSITY
The lithium-polymer chemistry provides extremely high energy density while still maintaining good cycle life and performance, which are desirable for subsea applications.
The design of the 1.5 kWh Subsea Battery allows a user to quickly replace a discharged battery with a charged one without ever opening a pressure vessel. This enables rapid turnaround of submersible equipment in the field.
With the fully automated charging system, full battery recharge can be accomplished in six hours or less.
