20100081047 | ELECTROLYZER MODULE FORMING METHOD AND SYSTEM - Embodiments of the present techniques provide electrolyzers made using thermoformed electrode assemblies and diaphragm assemblies. Each electrode assembly is made from two plastic rings and an electrode plate using a twin sheet thermoforming technique. A first plastic ring is laid in a mold having the appropriate shape to form the electrode assembly. The electrode plate is laid on top of the first plastic ring and is generally centered on the ring. The second plastic ring is laid over the electrode plate, and is generally centered over the electrode plate. The plastic is heated to soften the plastic, and a vacuum is pulled on the mold to pull the softened plastic into the shape of the mold. The mold is closed over the assembly to seal the two plastic rings together. After cooling, the molded part may be removed, resulting in a hollow plastic rim surrounding an electrode plate. | 04-01-2010 |

20100178548 | BATTERY PACK - In a battery pack according to the embodiment of the present invention, when coupling bosses of a second case are coupled to coupling holes of a first case, the first case and the second case can be easily coupled to each other by reducing the thicknesses of some portions of a rib having the coupling holes before the coupling bosses are coupled to the coupling holes. In addition, the first case and the second case can be smoothly coupled to each other at the initial step of coupling the coupling bosses and the coupling holes to each other by opening the outermost portion of the first case facing the top end of the rib having the coupling holes. | 07-15-2010 |
20110177379 | BATTERY ASSEMBLY - An end-to-end cell connection system for a battery assembly uses a conductive interconnector with an inner portion welded to an end of one cell, a standoff portion contiguous with the ring portion, tabs extending from the standoff portion, with the tabs welded to an end of another cell. By placing an insulator between the interconnector and the one cell, an electrical short is prevented in the event that a longitudinally coupled cell group is jostled. At the cell connections, there is a recess. To hold the cell group in place, the housing has a tab extending into the recess. The tab is at the center so that any dimensional variations are accommodated on each side of the tab. The interconnector also may include a receptacle for a thermistor to obtain a measure of battery assembly temperature. Diverter ribs may be provided in the housing to distribute flow to all cells. | 07-21-2011 |
