Einhorn Engineering worked with the University of Washington and Oregon State University to develop a seafloor-based, rechargeable battery system that will be integrated into an autonomous vehicle recharging station.
Einhorn Engineering designed a titanium pressure vessel to ASME Boiler and Pressure Vessel Code to withstand the pressure at a 100m depth. The pressure vessel houses and interfaces with a battery rack structure designed by Oregon State University. The pressure vessel mounts to a mudmat designed by Einhorn Engineering to resist the overturning moment caused by extreme wave conditions.
