Energy supply housing

Battery tray and power electronics in CAD representation

Different housings are used to protect electronic components, such as battery systems or power electronics, from external environmental influences and to attach the components to the interior in order to ensure that they function properly during vehicle operation. The requirements for the housing depend on the electronic system and drive concept. Different materials and manufacturing processes are currently used.


  • Unstable, thin-walled components (susceptible to vibration)
  • Construction as a cast tub or as a frame construction made of hollow profiles
  • Partly low-silicon aluminium
  • Large area (2 x 3 m)
  • Mainly drilling and milling operations and threading
  • Accuracy and surface requirements for cable bushing and cooling
