Energy supply housing
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.
