The interplay between the heat used and the heat required in vehicles is now more complex than ever. The thermal cycle of an electric motor differs fundamentally from that of a combustion engine. Thermal management is therefore a key technology for e-mobility and plays a central role in the efficiency of MEET.
The importance of this topic becomes clear when travelling in winter. While a combustion engine produces ample waste heat for heating the interior, the energy of an electric motor is barely sufficient to warm up the cabin air.
Electric cars do produce waste heat—for example, during battery charging—but significantly less than combustion engines. Dissipating this heat to protect the components, on the one hand, and utilizing it efficiently for air conditioning, on the other, is an important aspect of thermal management.
Performance, cruising range, charging times, and comfort—intelligent thermal management takes every aspect of MEET into account. Ultimately, all measures have the same objective: to use the available energy more efficiently in order to increase the cruising range.
Electric cars produce zero emissions locally, but MEET is environmentally friendly inside too—with the R744 air conditioning circuit, which relies on CO₂ as a 100% natural refrigerant. The system is therefore not only highly efficient, but also climate neutral.
- Improved thermal management for greater cruising range
- Short charging times require and facilitate the utilization of waste heat
- R744 air conditioning circuit with entirely natural and CO₂-neutral refrigerant
