Alke' partner in EU funded research project
Alke' is industrial partner and technical coordinator of JOSPEL project supported by a consortium of 14 project partners from 9 different EU countries. Objective of this project is:
- the development of a novel energy efficient climate system for the optimization of interior temperature control management in electric vehicles through an integrated approach that combines the application of the thermoelectric Joule and Peltier effect.
Main objective of JOSPEL is the reduction of at least 50% of energy used for passenger comfort and at least 30% for component cooling in extreme conditions with reference to electric vehicles currently on the market.
JOSPEL’s main energy efficiency improvements will consist of developing a novel and innovative heating system based on the Joule effect and a cooling system based on the use of Peltier cells (from which derives the name JOS-PEL). Both of these technologies are expected to reduce the energy consumption with at least between 25-30 % each in comparison with current heaters and heat pump inverters for cooling.
Alke' as industrial partner of JOSPEL project is in charge for the full integration, testing and validation of developed technologies into its electric vehicle platforms.

|Building a full monitorized “demo lab” with real users for the validation of the user cooler/heating feeling.|
With the impressive project results, JOSPEL contributes to breaking down one of the major barriers for a wider market introduction of electric vehicles.
Thermoplastic panels and thermoset textiles were developed as heating elements, thereby reducing the energy consumption with at least 30% compared to existing PTC heaters. Climatic chamber tests were carried out to simulate extreme climate conditions in the car, and the thermal comfort was evaluated with sensors (ISO14505-2) and real passengers (ISO14505-3). The JOSPEL heating solutions were close to perfection, as the warm body with fresh air from the fans resulted in a thermal comfort classification of neutral to slightly warm.
In addition, JOSPEL has applied optimized thermal management to the battery and other vehicle components, and by adding eco-driving technologies, the project has achieved further energy reductions of 24%.
Last but not least, lightweight technologies and improved cabin insulation using new glazing designs shaves an additional 3% off the energy consumption.
With this holistic approach to energy management, JOSPEL has reduced the energy consumption related to passenger comfort systems with a total of 57%. Moreover, the life of the electric vehicle battery was extended with 15% thanks to its improved thermal management.
