SeaPower addresses the space and weight taken up by an underwater vehicle’s energy supply. Kraken encapsulates lithium-ion cells in a pressure-tolerant polymer matrix, avoiding the conventional pressure housing or oil compensation around the battery. The battery-management system monitors cell temperature and voltage and provides telemetry and software power control.
Kraken describes configurable systems from 2 kWh to 5 MWh and a 6,000 m depth rating. Those are family-level options, not the specification of one universal module. In an unnamed customer example, it reports increasing a UUV’s capacity from 48 to 96 kWh within the same volume and reducing weight per kWh by 46%. That is useful evidence of the claimed packaging benefit, with the configuration and comparison still belonging to that example.
Reported orders identify real integration routes, including Teledyne Marine’s planned Gavia and SeaRaptor work. Electrical, mechanical and safety compatibility must still be established for the selected vehicle; the brochure’s design-for-compliance wording is not proof of every certification.
