Thermal management in electric vehicles

It would seem that all you need to design an electric vehicle is to remove the combustion engine and components for engines of internal combustion fossil fuels and replace them with electric motors with batteries or fuel cells. But it is not that simple. In addition to fixing the main components and designing the installation of the basic systems, you must remember to provide them with optimal thermal operating conditions. In simpler terms, to ensure that they are neither too cold nor too hot.

Modern electronics, electric drives, batteries, or fuel cells require precisely defined operating parameters within which they can operate with maximum efficiency. By ensuring these, we can count on the machine to function faultlessly over a long period and with high environmental efficiency, while increasing its operating range even by up to 20%. One of the most important factors influencing this is the operating temperature of individual components. Studies show that a change of just a few degrees in this temperature can reduce the service life of electronics by 50%. It should therefore be optimal and as independent as possible of environmental conditions.

Thanks to our high-level system know-how in conventional, hybrid, and electric machines, our designers are developing the necessary systems for utilizing residual heat from electric motors or heat accumulated during fast battery charging. In the age of electromobility, we select high-performance components and design systems for comprehensive heat management in electric and hybrid vehicles, so that working with NG Engineering allows our customers to achieve maximum satisfaction.
