Since the electric vehicles are motorized to different degrees, there is often a need for different capacity accumulators. The different efficiency of the accumulators goes. an altered, i. different size of the accumulators with. This has the consequence that for electric vehicles of different levels of motorization each individually different sized battery case needs and must be made and thus the frame of such vehicles in which such battery case are integrated to change.
  • Such electric vehicles in this case have a monotube frame structure, ie are equipped with a frame which consists of a main pipe.

Since the batteries for the electrically powered vehicles are relatively heavy due to their high lead content, this property is often exploited by a special arrangement of the batteries or the battery case on the electric vehicle.
  • the frame ie the tube, is therefore provided with and designed for custom-made constant size battery receiving boxes, with the battery box boxes often located in the foot area laterally or below that portion of tubing located in that area.
