Abstract: A storage tank having a wire or wire winding embedded in the wall of the storage tank is disclosed. The wire may be positioned such that it is compromised if the storage tank is deformed to a certain degree. The wire, for example, may form a helical shape proximate to the outer surface of the wall of the storage tank.

Abstract: A mounting assembly for a vehicle is provided. The vehicle has a chassis with a first frame rail and a second frame rail extending longitudinally.

The bracket has a first end region connected to the first frame rail to position the tank on an outboard side of the first frame rail.

Abstract: A fuel storage vessel includes a valve operatively associated with the storage vessel, a conduit disposed within the vessel and in fluid communication with the valve for delivering a stream of pressurized fuel to the storage vessel and a detector adjacent the conduit for detecting a state of the pressurized fuel in the storage vessel. The detector is positioned outside of the stream of pressurized fuel.

In one embodiment, the hybrid hydrogen storage system includes: a first hydrogen storage material present at a first volume percent (%) having a first gravimetric capacity and a first volumetric capacity; and a second hydrogen storage material forming an unreacted mixture with the first hydrogen storage material and present at a second volume % being 100 volume % minus the first volume %, the second storage material having a second gravimetric capacity and a second volumetric capacity, the first gravimetric capacity at the first volume % being higher or lower than the second gravimetric capacity at the second volume %, and the first volumetric capacity at the first volume % being the other of higher or lower than the second volumetric capacity at the second volume %.

Abstract: Disclosed is a thermal protection system for a pressurized gas cylinder. The system includes a pressurized gas cylinder 2, a temperature-activated pressure relief device 4 coupled with the pressurized gas cylinder 2, a thermal concentrator 6 integrated with an opening 10 in a vehicle panel 8, the panel being located in proximity to the cylinder; and an opening in the concentrator 6 directed toward the pressure relief device 4. The concentrator may be a funnel shaped shield, flange or metal channel. Accelerant 24 and wicking materials 20, 22 may be used to aid flame progression.

Abstract: A system for integrating and embedding a fuel storage tank in the roof of an automotive vehicle is provided. The automotive vehicle may include a roof assembly having inner roof panels and outer roof panels. The roof panels may define a cavity that protrudes into the passenger compartment below the roof line of the automotive vehicle. A pressurized fuel tank may be disposed within the cavity of the roof assembly.

Abstract: The invention relates to a fuel retention monitoring system for a pressurized hydrogen storage tank on a vehicle. The vehicle includes a hydrogen dispensing system having a plurality of conduits for carrying a hydrogen gas. The conduits have at least one connection linking them together. The monitoring system includes a vapor concentrator for the hydrogen gas, shrouding a first one of the connections. The first connection has a parting line where the conduits forming the connection meet. The vapor concentrator may be positioned above the parting line of the first connection and may include a periphery and a top defining a headspace cavity. The monitoring system further includes a hydrogen gas sensor locatable adjacent to the headspace cavity and capable of providing a signal correlated to a hydrogen gas concentration in the headspace cavity.

Abstract: The invention is an improved method and system to fuel a vehicle such as a hydrogen-powered vehicle. The present invention vents air into a fuel fill line within the vehicle from a fuel fill receptacle to the vehicle's fuel storage tank. The invention eliminates or reduces inadvertent fuel ignition from electrostatic discharge in and around a vehicle fuel line during fueling. Just prior to fueling, the invention vents the fuel line in between two of a plurality of fuel line check valves closest to the receptacle. The invention can be configured to activate the vent system where a first switch indicates vehicle fueling is imminent (such as a fuel fill door is opened) and a second switch indicates that the receptacle is not attached to a fuel source. The system can also be configured to deactivate if the first switch indicates fueling is not imminent (the fuel door is closed), or the second switch indicates that the receptacle is attached to the fuel source.

Abstract: An electric vehicle battery tray includes a base having an inner surface and an outer surface, a front and back wall having outer and inner surfaces adapted to overlay the base outer surface and to create substantially planar, vertical front and back wall inner surfaces thereby, and a left and right side wall having outer and inner surfaces adapted to longitudinally overlay the base outer surface and to create substantially planar, vertical left and right side wall inner surfaces thereby.

Abstract: A battery tray assembly that includes a first member having a first interface surface and a first battery retaining surface. The first retaining surface retains a top surface of a first battery. A second member having a second interface surface and a second battery retaining surface retains a bottom surface of the second battery. A means for securing the first interface surface to the second interface surface joins the two batteries in a fixed position. The securing means may include a series of projections on one or both separator members and corresponding slots. A greater number of slots than projections enables a plurality of orientations between the first and second members.
