Increasing energy efficiency with new sub systems

Over the past six months, JOSPEL partners have been working on the development and optimization of those sub systems, which later will be integrated in to the test vehicles. Together, the subsystems will constitute a new energy efficient climate system, which contributes to increase the operating range of EVs.

EV motors and batteries do not create heat in the same way as other engines and therefore requires specific thermal management solutions. Current heating, ventilation, and air conditioning technologies reduce the EVs potential operating range with up to 25%.

Over the past six months, the partners have been developing subsystems, which later in the project will be joined together as a novel energy efficient climate system for EVs with the purpose of increasing the operating range.

Reduced battery consumption with new heating system 

JOSPEL is developing a new heating system based on resistive heating. Here, new polymeric materials have been developed with high electrical conductivity. These materials will be integrated in the plastic parts of the car in order to facilitate direct heating of the passenger and thereby avoiding heating the whole cabin. This makes the car more efficient in terms of battery consumption. Next step will be to evaluate the durability and reproducibility of the heating behavior of the heating systems.

 

New cooling system reduces power consumption by 15%

By means of new thermoelectric materials and devices, the project has designed different cooling systems and has been further defining and evaluating the optimum locations in the car. With the new cooling systems, an important milestone in the project has been successfully achieved as the thermoelectric system is reducing energy consumption with at least 15% in comparison with current solutions.

Defrosting windows with infrared LED lights

The project is studying how it is possible to defrost Plexiglas (PMMA) windows and front glas windows in EVs. Here, JOSPEL is applying infrared LED lights to decrease the defrosting time. By implementing infrared subsectors in the windows, it is possible to absorb the electromagnetic energy and transform it into heat, allowing a fast and effective defrosting of the windows.

Integrating subsystems into one system

Partners are working closely to ensure the successful integration of all sub systems, so that their behavior will be maintained when integrated into the vehicle. The interrelation and coordination of all the subsystems will allow JOSPEL project to meet its target of an overall energy reduction of 25%.
