Electromagnetic shielding: a key to safe electromobility
Ensuring the electromagnetic compatibility (EMC) of all vehicle components is a major challenge in electromobility. Electrically powered vehicles in particular require reliable shielding against electromagnetic interference in order to protect both technical systems and people.
With the electrification of the drivetrain and the increasing integration of sensors for autonomous driving, the importance of EMC is constantly growing. Interference signals can have serious consequences, ranging from undesired switching processes to loss of control capability.
Challenges and requirements
Sensitive electronic modules, the need for faster inductive charging and high currents and voltages with short switching times place high demands on effective EMC-compliant shielding. These requirements are clearly regulated in EU Directive 2014/30/EU and make precise technical implementation essential.
Efficient solutions with metal mesh
Metal mesh has been a proven material for electromagnetic shielding for many years. Their mechanical and electrical properties can be precisely adapted to specific requirements. Particularly in the MHz range relevant for the on-board electronics of electric vehicles, meshes made of flat or round copper or aluminum wires offer excellent shielding attenuation. Metal meshes also offer further advantages such as vapor permeability and high spatial flexibility.
Thanks to their malleability and stability, they can be used both for laying small components in complex installation situations and for large-area shielding, for example of high-voltage batteries. Mesh elements can also be equipped with punched or bent parts or contact springs, which creates a wide range of possible applications. The combination of these properties makes metal mesh a crucial component for the safe and flexible electromagnetic shielding of modern electric vehicles.
