US$7.5M JOSPEL project to develop energy efficient climate control for EVs; leveraging Joule and Peltier effects
A trans-European collaboration aims to develop a novel energy efficient climate control system to help reduce the energy used for passenger comfort in electric vehicles by at least 50%. Even in today’s modern electric vehicles, a lot of energy is wasted on heating or cooling, in turn limiting the already relatively short range by further draining the battery capacity.
The aim of the €6.7-million (US$7.5-million) JOSPEL project is to develop an efficient, electrical climate control system using an integrated approach that combines the application of the Joule and Peltier effects; efficient insulation of the vehicle interior; energy recovery from heat zones; increased battery life as a side effect of thermal management; reduced battery energy consumption via the integration of Peltier cooling; innovative automated and eco-driving strategies; and the electronic control of power flows.
Joule heating refers to the conversion of the energy of an electric current into heat as it flows through a resistance; when current flows through a solid or liquid with finite conductivity, electric energy is converted to heat through resistive losses in the material. The Peltier effect is the presence of heating or cooling at an electrified junction of two different conductors.
The main objective is the reduction of at least 50% of energy used for passenger comfort (<1,250 W) and at least 30% for component cooling in extreme conditions with reference to electric vehicles currently on the market.
Besides improving on the heating/cooling technology through thermoelectric technology and effects, JOSPEL will also enhance the energy and battery efficiency through various other solutions, such as improving on the insulation via new glazing designs, reducing the energy needed to defrost and so on.
Industry and research partners from the involved companies and organisations in Spain, Croatia, Italy, United Kingdom, Luxembourg, France, Portugal, Denmark and Germany recently met in Valencia to align expectations and aims of the project.
The JOSPEL project is ambitious in size and scope, and we believe to be able to reduce not only the energy used for passenger comfort heating with at least 50%, but also to reduce the energy used for component cooling in extreme conditions with at least 30%. Both objectives will help make the electric vehicles much more energy efficient and marketable.—Cristina Abad, AIMPLAS, project coordinator
The JOSPEL project has received funding from the European Union’s Horizon 2020 research and innovation program under Grant Agreement Nº 653851.
