Disclosed is a system for controlling gaseous hydrogen (GH2) refueling of a GH2 vehicle, wherein a vehicle fuel tank is refilled with GH2 from an external supply tank. The system includes a target patch or a cell of a temperature-dependent reflectivity material on an exterior of the vehicle fuel tank, and a sensor package including an electromagnetic (EM) radiation emitter and a radiation detection system positioned remote from the vehicle tank being filled. The sensor package is located on or adjacent an external refueling device with a line of sight to the target patch or cell.
A system for controlling gaseous hydrogen (GH2) refueling of a GH2 vehicle, wherein a vehicle fuel tank is refilled with GH2 from an external supply tank, said system comprising an unpowered temperature sensor comprising a patch or a cell of a temperature-dependent reflectivity material on an exterior of the vehicle fuel tank, and a sensor package comprising an electromagnetic radiation emitting system and a radiation detection system positioned remote from the vehicle tank being filled, wherein the sensor package is located on or adjacent an external refueling device with a line of sight to the unpowered temperature sensor patch or cell.
A method for controlling refueling of a hydrogen (H2) fuel-cell-powered vehicle, said vehicle having a fuel tank configured to hold a quantity of compressed GH2 from an external filling device, said method comprising providing on an exterior of the vehicle fuel tank an unpowered temperature sensor comprising a patch or cell of a temperature-dependent reflectivity material, interrogating the unpowered temperature sensor patch or cell with a radiation emitting system and radiation detector system positioned remote from the vehicle tank with a line of sight to the unpowered temperature sensor, and controlling delivery of said GH2 in response to detected changes in reflection of said temperature-dependent reflectivity material.
