Abstract:
1. A warming system for directly heating an onboard high pressure gas storage tank for a vehicle, comprising: a vehicle mounted storage tank system adapted to contain a consumable high pressure fuel for a vehicle, the storage tank system including a storage tank and inlet and outlet flow assemblies, at least a portion of the storage tank being formed of ferromagnetic active material; an induction coil at least partially circumscribing at least a portion of said portion of the storage tank formed of ferromagnetic active material; a power source for supplying an alternating electrical current to the induction coil and creating an alternating electromagnetic field about the storage tank, said ferromagnetic active material in the storage tank being responsive to the alternating electromagnetic field to generate heat; and a temperature control system, the temperature control system including sensors for detecting a temperature of the storage tank system and a temperature of fuel within the tank, the temperature control system being operative to measure and control the temperature differential between the fuel storage system and fuel contained therein and maintain the detected temperature of the storage tank system above a predetermined lower temperature limit by varying said electrical current supplied to the induction coil in response to temperatures detected by the sensors.
