According to foreign media reports, after about three and a half years, the JOSPEL project recently announced that it has successfully completed a new energy efficient climate control system (energy efficient climate control system). This technology can help electric vehicles reduce energy consumption while ensuring passenger comfort. Consume. The system can save over 57% of the energy consumption of automobile heating and cooling systems, optimize heat management and environmentally friendly driving technology, reduce the weight of the vehicle body, and enhance the insulation effect of the vehicle's cockpit.

The core of the project is the Joule heating effect and the Peltier effect, which have great potential for reducing the energy consumption of heating and cooling of the electric vehicle cockpit.
The total project budget is 6.7 million euros (approximately RMB 52.68 million), which has been obtained from the European Union Horizon 2020 R & D and innovation project. The heating system based on the Joule effect will perform radiant heating in the cockpit, combined with the ventilation system to continuously inject fresh air, thereby improving passenger comfort.
Thermoplastic panels and thermoset textiles are developed as heating elements, which reduce energy consumption by at least 30% compared to existing PTC heaters. The artificial climate chamber test was used to simulate the extreme weather conditions of the car, and the thermal comfort of the car was evaluated using sensors (ISO14505-2) and real passengers (ISO14505-3).
In addition to developing these new heating and cooling systems, JOSPEL has also optimized thermal management of batteries and other vehicle components. In addition, by adding green drive technology, an additional 24% reduction in energy consumption was achieved. For its part, lightweight technology and the use of new glass designs in the cockpit to improve thermal insulation have reduced energy consumption by an additional 3%.
