Innovative power system for autonomous underwater vehicle

摘要: The present paper proposes a study for the integration of hybrid power system composed by rechargeable batteries and fuel cells with chemical gas storages an Autonomous Underwater Vehicle (AUV) or Unmanned Undersea Vehicles (UUV). AUVs UUVs are vehicles that primarily used to accomplish oceanographic research data collection auxiliary offshore tasks. At time they usually powered lithium-ion secondary batteries, which have insufficient specific energy. In order enhance usage these exploit their capabilities increased endurance is required. Fuel Cell Energy Power Systems (FCEPS) been identified as effective means achieve this endurance[1]. From literature it could be found technology AUV based on implemented some form battery management system. improve autonomy different technologies should used. state art represented HUGIN AUV[2]. This vehicle Alkaline Aluminium/Hydrogen peroxide semi-fuel cell. will alternative generation Proton Exchange Membrane (PEM) cell fed pure hydrogen oxygen produced replaceable storage AUV. A technical sizing has done, supported analysis performance considered technologies. Standard AUV-UUV works daily operational profile thus about 24h autonomy. FCEPS UUV requires particular characteristics installed exploited. Starting from statistical assessment existing military civil application most suitable dimensions, weight done together requirements operative conditions in identify profitable target parameters future market development technology. innovative aluminium-water reaction introduced first time. consider performances developed Technion Institute Haifa (Israel), evaluation theoretical achievable it's exploitation matching System (FCS). An FCEPS, combination FCS system, through procedure proposed Davis More[3] considering best FCS. gives methodology calculate key permit comparison between systems. Moreover method also other researchers today available wide database systems available.
