Abstract: A nickel-hydrogen storage cell (12) having means within the pressure vessel (40) of the cell (12) for shorting the cell when the cell fails because of an open circuit condition, so that a battery (10) containing the failed cell continues to provide electrical storage capability at a voltage diminished only by that of the failed cell. A shorting plate set (50) within the pressure vessel (40) and in parallel with the active plate sets (18) includes a silver electrode (54) that is normally inert, but which dissolves in the electrolyte of the cell (12) when the discharge voltage across the cell increases to a large negative value, indicating open circuit failure of the cell. The silver then plates out onto the normally positive nickel electrodes (20) so that the silver eventually bridges the gap between the nickel electrode (20) and the silver electrode (54), and shorts them, thereby also shorting the cell.

Abstract: A process for preventing electrical capacity loss during storage of a pressurized nickel-hydrogen electrical storage cell. An electrical precharge is applied to the positive electrode of the cell, so that discharge of the cell is negative electrode limited. In one approach, the cell is charged, while sealed, to a state of charge corresponding to a first gas pressure, and then the hydrogen pressure is reduced to a lower value, preferably about atmospheric. In another approach, a current is passed through the cell while the cell is unsealed and maintained at atmospheric gas pressure, until the cell reaches the desired state of charge.

Abstract: A process and apparatus for controlling the charging of pressurized gas-metal cells such as nickel-hydrogen cells, to prevent detrimental overcharging, wherein the time rate of change of a battery gas pressure index is monitored as a control parameter. When the time rate of change of the index falls below a preselected value, charging is discontinued. The cell gas pressure index can be gas pressure itself, or a quantity which is reponsive to, and depends upon gas pressure, such as the deformation of a cell component.

Abstract: Procédé permettant d'empêcher la perte de capacité électrique pendant l'entreposage d'un élément d'accumulateur électrique au nikel-hydrogène sous pression. Une décharge électrique est appliquée à l'électrode positive de l'élément, de manière à limiter à l'électrode négative la décharge de l'élément. Dans une forme d'exécution, l'élément est chargé, lorsqu'il est scellé, jusqu'à un niveau de charge correspondant à une première pression de gaz, la pression d'hydrogène étant ensuite réduite jusqu'à une valeur inférieure, de préférence de l'ordre de la pression atmosphérique. Dans une variante, on fait passer un courant à travers l'élément, celui-ci n'étant pas scellé et étant maintenu à une pression de gaz équivalente à la pression atmosphérique, jusqu'à ce qu'il atteigne le niveau de charge désiré.

Abstract: Pocédé et appareil permettant de contrôler le chargement d'éléments gas-métal préssurisés tels que des éléments nickel-hydrogène, afin de prévenir une surcharge dommageable, la cadence de modification d'un indice de pression du gaz d'un accumulateur étant surveillée en tant que paramètre de contrôle. Lorsque la cadence de variation de l'indice tombe au-dessous de la valeur présélectionnée, le chargement est interrompu. L'indice de pression du gaz de l'accumulateur peut être la pression gazeuse elle-même, ou une grandeur qui est sensible à la pression gazeuse et qui dépend de cette dernière, telle que la déformation d'un constituant de l'élément.

Abstract: Elément accumulateur (12) au nickel-hydrogène, doté d'un moyen à l'intérieur du récipient pressurisé (40) de l'élément (12) permettant de court-circuiter ce dernier en cas d'une défaillance occasionnée par une condition de circuit ouvert, de sorte qu'une batterie (10) dont fait partie l'élément défectueux continue à servir d'accumulateur électrique, la tension étant diminuée uniquement de la valeur de tension de l'élément défectueux. Un ensemble (50) à plaquette de mise en court-circuit disposé dans le récipient pressurisé (40) et relié en parallèle avec les ensembles (18) à plaquette active, comporte une électrode d'argent (54) qui est normalement inerte, mais qui se dissout dans l'électrolyte de l'élément (12) lorsque la tension de décharge de l'élément atteint une valeur négative importante, indiquant ainsi la défaillance de l'élément due à un circuit ouvert. L'argent se dépose alors sur les électrodes de nickel (20) normalement positives, et finit par combler le vide entre l'électrode de nickel (20) et l'électrode d'argent (54) provoquant ainsi un court-circuit entre celles-ci, ainsi qu'entre l'élément et les autres.
