JOSPER Wants the Climate Control in Your EV to Become 50% More Efficient

Although we call them cars just like the ones using a traditional internal combustion engine, EVs have special needs that carmakers are continually addressing to improve their products. Think of their aerodynamic bodies for instance, but how about the A/C system's efficiency in EVs?
This is where the €6.7 million ($7.5 million) JOSPER project comes into play. The initiative's primary goal is to offer an energy-efficient climate system for the optimization of interior temperature control management in electrical vehicles. That's almost Chinese at first sight, so allow us to clarify things a bit.

The JOSPER signature comes from putting together the Joule and Peltier names, as in the Joule and Peltier effects. In case you're not familiar with this area of physics, here's more intel on the matter.

Joule heating, for example, refers to an electric current's energy into heat as it passes through a resistance. In real-life scenarios, 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 denotes the presence of heating (or cooling) at an electrified connection between two different conductors.

Based on this principles, JOSPER aims at reducing 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. As a result, EVs will become "much more energy efficient and marketable," according to Cristina Abad, AIMPLAS, project coordinator, cited by Green Car Congress.

If JOSPER is successful, the beneficial effects will be reflected in the maximum range offered by the car, which means fewer reasons for range anxiety and more reasons for drivers to buy electric.
