Kraken - Pressure Tolerant Encapsulated Components
Kraken Robotics (through its invest company, Kraken Power) has developed a new method of creating cost and space efficient pressure tolerant electronics and batteries. Kraken’s pressure tolerant batteries use Lithium-Polymer cells which are encapsulated by a durable silicone polymer that remains flexible, yet stable under pressure. This method of encapsulation allows Kraken to reduce the size and weight of traditional subsea battery packs by not requiring the cells to be located inside pressure housings or flooded with oil. As such, the battery design is no longer constrained by dimensions of the pressure or oil housings. They can now be contoured to better fit the shape of the vehicle, which improves packing efficiency and increases volumetric density. Ultimately, this technology reduces the size of high density battery packs for underwater vehicles and dramatically reduces the cost and weight versus traditional subsea batteries.
Products Details
Kraken Pressure Tolerant Battery Systems are modular and can be connected in banks to meet the vehicles voltage and capacity requirements. Each pack is individually rated to 6000 meters and contains its own Battery Management System (BMS). This provides status of the individual cells and the pack as a whole with data interfaces through RS-232/RS-485 and CANBus.
Kraken Robotics’ 6,000 meter rated silicone encapsulated pressure tolerant battery packs which contain individual battery management systems enabling smart links to achieve any desired capacity.
