SUBSURFACE MARINE BATTERY PACK

Abstract:

A subsurface battery system includes a ballast mass at the seafloor, a deep-sea electronics module, having an interface to seafloor payloads, and a subsurface buoyant pressure vessel having a battery. The ballast mass is attached to the deep-sea electronics module. The deep-sea electronics module is connected to the battery. The subsurface buoyant pressure vessel is submerged to a water depth of approximately 50 meters to 500 meters. The system is used for powering the seafloor payloads.
