Abstract

A product may include a storage vessel that may define a first port opening into the storage vessel, and that may define a second port opening into the storage vessel. A first fill conduit may be connected to the storage vessel at the first port. A second fill conduit may be connected to the storage vessel at the second port. A control mechanism may be connected with the first and second fill conduits. A supply conduit may be connected to the control mechanism. The control mechanism may provide a flow path from the supply conduit to at least one of the first or second fill conduits to fill the storage vessel.

First claim

What is claimed is:

1. A product comprising a storage vessel that has a plurality of storage cells arranged in series, the plurality of cells including first and second end cells and intermediate cells between the first and second end cells, each two adjacent cells of the plurality of cells interconnected by a connecting conduit, the storage vessel defining a first port that opens into the storage vessel at the first end cell, and defining a second port that opens into the storage vessel at the second end cell, a first fill conduit connected to the storage vessel at the first port, a second fill conduit connected to the storage vessel at the second port, a three-way valve connected with the first and second fill conduits, and a supply conduit connected to the three-way valve, wherein the three-way valve is configured to provide a flow path from the supply conduit to the first fill conduit and alternatively to both the first and second fill conduits to fill the storage vessel.

2. The product according to claim 1 comprising a temperature sensor disposed to monitor heat in the storage vessel and a controller in communication with the temperature sensor, wherein in combination with the three-way valve, the controller effecting modulation of the three-way valve, which is configured to modulate fill of the storage vessel between the first and second fill conduits in response to changes detected by the temperature sensor, the controller configured to direct fill to the second fill conduit to cool a segment of the second end cell.

3. The product according to claim 2 wherein the controller is configured to provide mixing of a locally hot fuel in the storage vessel with a cold incoming fuel by active cycling between filling the storage vessel through the first fill conduit and filling the storage vessel through the first and second fill conduits on an ongoing basis during fill of the storage vessel, in its entirety.

4. The product according to claim 1 comprising a pre-cooler disposed in the supply conduit to effect cooling of a fluid supplied to the storage vessel prior to delivery into the storage vessel to offset heat generated during fill of the storage vessel, and a flow control unit disposed in the supply conduit between the pre-cooler and the three-way valve, the flow control unit configured to close the supply conduit.
