  • Patent number: 5128221
    Abstract: A storage battery (10) comprises several cells (1) enclosed within a housing, each cell containing electrolyte and plates coated with positive mass, negative mass, and positive and negative mass on different sections thereof. The cells are separated from each other with separator plates (14), and the requisite electrically conducting connectors are provided for connecting the plates and/or cells. Each cell (11) contains positive and negative plates (12,13,15). Each cell (11) is packed in an individual electrically insulating housing (16) so that merely the ends (12a,13a) of the plates (12,13) need to be electrically interconnected, respectively. The ends (12b, 13b) of the plates (12,13) are connected to the terminals (17,18) which emerge from the housing (16) to be electrically connected. For providing electrical conductivity, the spaces between the cells (11) and the end walls of the outer cells (11) are made electrically conductive with an electricity conduction joint (19).

  • Patent number: 4973533
    Abstract: The present invention concerns a gas vault structure for a storage battery having one or several cells enclosed in a housing, each cell containing electrolyte and monopolar plates and/or bipolar plates separated from one another by separator plates and coated with positive and/or negative mass, along with requisite electrical connectors interconnecting cells and/or plates. The gas vault structure is arranged to serve as an inner core for producing a gas space during casting of the housing of the storage battery, and/or of the cover, and/or of the partitions separating the cells.

  • Patent number: 4966346
    Abstract: A mounting device secures a storage battery (10) to a base. The device comprises a footing (20-28) to be rigidly fixed to the base (B) and being loose from the battery (10). Locking elements (16-19) of the device are pivotally mounted on the storage battery (10). The storage battery (10) is detachably fastened with the aid of the locking elements to the footing (20-28) through the action rapid locking elements. The locking elements (16-19) are pivotally mounted on a cover (12) of the storage battery (10). Carrying handles (16) are provided for lifting the storage battery (10) from the footing (20-28) when the locking elements (16-19) are turned to the open-position. In addition, shields (17) are provided in the locking element to protect the storage battery terminals (13) when the locking elements (16-19) are turned to locking position.
