Patent ID: 8720500

Claim:
A system comprising: a high pressure gas storage tank; a refueling tube in fluid communication with the tank; a refueling receptacle coupled to an end of the refueling tube opposite to the tank and being adapted to accept a refueling device that allows gas to flow through the refueling tube and into the tank; a temperature sensor mounted on or proximate to the tank for measuring the temperature of the tank and providing temperature signals indicative of the temperature of the tank; a controller responsive to the temperature signals from the temperature sensor; a power source providing a supply voltage to the controller on a first electrical line; and a first temperature switch mounted to the tank and being electrically coupled to the first electrical line, said first temperature switch having a first temperature set-point such that if the first temperature switch detects a temperature above the first temperature set-point the first temperature switch will close and allow the supply voltage from the power source to be provided to the controller.
