Abstract
A storage battery has an axially extending housing divided into axially extending blocks each containing a plurality of individual cells. The housing has a pair of plus-minus contact terminals equal to the number of blocks with the terminals accessible from the exterior of the housing. Voltage is supplied to each pair of terminals corresponding to the sum of the voltage of the cells within one block. The charging operation in the individual blocks is performed consecutively in an appropriately shaped charging device having a charging voltage corresponding to the voltage of one block. The voltage of the individual blocks can be utilized in series or in parallel connection by an appropriate electronic arrangement within an electrically driven tool.
Claims6
A storage battery, comprising:
- a housing having a central axis;
- at least one block located in said housing and having an axis, which extends parallel to the central axis of the housing, and at least one individual cell;
- and
- a coupling part located at one end of said housing and having an outer end surface and at least one pair of plus-minus contact terminals associated with said at least one individual cell and accessible at said outer end surface;
- wherein said coupling part extends transverse to the central axis of said housing, wherein said outer end surface is divided at least into two equal areas, and further wherein the at least one pair of contact terminals is accessible at one of said at least two equal surface areas.
A charging device for a storage battery including a housing and at least one block located in the housing and comprising at least one individual cell, said charging device comprising a coupling part having a surface area, which is divided into at least two equal parts, and at least one pair of plus-minus contact terminals,
- wherein at least one of said at least one pair of contact terminals is accessible at least at one of said at least two equal parts.
