Requirements for battery enclosures – Design considerations and practical examples

Requirements for battery housings in e-vehicles are extensive: regulatory requirements; functional requirements; consideration of the installation conditions, transformation of forces and torques into the vehicle structure as well as wishes and demands of the end customer for trouble-free operation under a wide variety of climatic conditions.Space and weights are scarce resources in electric vehicles; this means lightweight construction and multifunctionality are stringent requirements for all functional units. The multifunctional battery housing - the B: HOUSE® in GVI® technology - offers new and highly efficient solutions.This concept allows effective passive and active thermal management, vibration and crash-proof housing and fixation of the battery cells/ modules, fire protection in all directions, EMC safety, environmental protection, lightweight construction – which means resource saving and weight-optimization in one functional unit.
