Could better HVAC increase the range of e-cars?

Could better HVAC increase the range of e-cars?

Battery-electric vehicles have a temperature problem: In wintertime, the battery performance already suffers from low temperatures. And then its energy should be wasted to heat the car? The JOSPEL research projects is exploring ways to reduce the energy consumed by HVAC systems. The goal is ambitious: 50% savings.

The aim of the 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 – in many cases this effect is unwanted since it reduces the energy efficiency of the respective device with heating being more or less the only exception. The Peltier effect is the presence of heating or cooling at an electrified junction of two different conductors.
The main objective of the JOSPEL project 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 compared 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 innovative glazing designs, reducing the energy needed to defrost and so on.

Industry and research partners from the involved companies and organisations from Spain, Croatia, Italy, United Kingdom, Luxembourg, France, Portugal, Denmark and Germany recently met in Valencia to align expectations and aims of the project. It is coordinated by plastics research institute AIMPLAS (Paternas, Spain). The European Union funds the project within its Horizon 2020 programme with €6.7 million (about $7.5 million)
