In addition to a multitude of challenges, developers and manufacturers of electromobility solutions are faced with complex tasks, particularly in the areas of “electromagnetic compatibility” and “thermal management”. This includes the entire vehicle and battery technology as well as the charging infrastructure. As one of the leading solution providers for EMC and thermal management, MTC Micro Tech Components GmbH has comprehensive industry knowledge and know-how with 30 years of experience.

Customised EMC solutions for e-mobility applications
In terms of electromagnetic compatibility, e-mobility places completely new demands on the automotive industry as well as the associated charging infrastructure. The coexistence of high-voltage (HV) and low-voltage (LV) electrical systems with spatially and electrically connected components requires consistent avoidance of electromagnetic interference. In the electric motor for drive and energy recovery as well as in the traction battery with corresponding charging technology, large electrical powers are converted that can lead to interference emissions in a broad frequency spectrum. For example, inverters and converters cause considerable electromagnetic interference in the HV on-board network, which can have a negative effect on sensitive electronic components of the LV on-board network via coupling paths.

MTC offers EMC shielding materials such as conductive foam or fabric and aluminium gaskets with a wide variety of material properties, sizes and shapes for these diverse applications. Thus, almost any conceivable challenge regarding electromagnetic interference can be implemented together with the customer. In addition, EMC metal parts, such as contact springs, enable gaps and distances between housing parts or printed circuit boards to be bridged so that electrical contacting is permanently and reliably ensured. These and other EMC components are available from MTC as standard or customised solutions, so that the individual requirements of the application can be optimally met.

Thermal conductive materials for thermal management in electromobility
The electric powertrain, battery and charging technology and numerous electrical control and regulation systems generate heat loss during operation that must be effectively dissipated from the respective component. Thermally conductive materials such as gap pads with excellent form modification or dispensable 1 K or 2 K gap fillers ensure seamless thermal connection between heat source and heat sink. Insulating air gaps, unevenness, curvatures and tolerances are reliably closed and compensated.

The optimised thermal management thus ensures the long-term reliability and performance of heat-sensitive electronics, components and modules. The silicone-based thermal management materials are also available as silicone-free variants. The team of experts at MTC Micro Tech Components GmbH also offers extensive consulting, prototyping and development support. In this way, the right EMC or thermal management solution can be found for every task and problem in close cooperation with the customer.
