  • the cells are stacked on one another, wherein the corresponding cover plates used as poles electrically contact the individual battery cells.
  • the stack of individual battery cells is then closed at its ends by pole plates and pressed over corresponding clamping means.

In practice, this means that from this point on entire further assembly of the battery, taking into account appropriate
  • Safety regulations for higher voltages must be made. This includes, for example, special precautions such as protective equipment, specially trained personnel and the like. As a result, the cost of mounting such a battery is significantly increased.

  • This structure makes it possible to stack the battery individual cells during assembly of the battery and to keep it in the unstressed or a partially locked state. In this construction phase there is no high voltage on the components of the battery. Therefore, can be dispensed with special measures during assembly, so that the assembly can be performed easily and inexpensively. Only in the final stage of assembly, the clamping means are clamped accordingly, so that the battery or the cell stack changes from its partially locked state to the clamped state. In this case, then the elastic, electrically insulating material is compressed so far that it leads to a contacting of the battery cells
  • Another particular advantage of the invention is that even with a disassembly of the battery, after the strained state has been transferred by loosening the clamping means in a partially braced or unstressed state, the elastic material expands so far that the battery individual cells separated again become. Then, for example, at a disassembly after relaxing the cell stack can be worked without appropriate protective measures due to the high voltage of the battery.

It is sufficient if, after some of the cells, such an element is arranged between the cells. In this way, groups of individual battery cells form between the ends of the battery and the locations with the elastic material or second locations with the elastic material.
