JOSPEL

A novel energy efficient EV climate system

Overview

Research shows that a major barrier to the purchase of electric vehicles (EVs) is the limited operating range compared to the majority of the available car models on the market. The main ways to increase the operating range of an electric car are: to increase the engine efficiency, to improve the battery efficiency, to reduce the mass of the car and/or, to improve the energy use in the car.

The project will target the energy consumption challenge by focusing on improving energy consumption of the vehicle and battery efficiency; to get more available energy for mobility and consume less energy from the grid. EV motors and batteries do not create heat in the same way as internal combustion engines and therefore require specific thermal management solutions. Current HVAC (heating, ventilation, and air conditioning) technologies reduce the EVs potential operating range by up to 25%.


Project end date

October 2018


Aims

The primary aim is the development of a novel energy efficient climate system for the optimisation of interior temperature control management. This integrated approach combines the application of the thermoelectric Joule and Peltier effects, the development of efficient insulation of the vehicle interior and energy recovery from heat zones. Battery life will increase in duration due to enhancement as a side effect of thermal management. Battery energy consumption will reduce by Peltier cooling integration, innovative automated and eco-driving strategies and the electronic control of power flows.

The main objectives are 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.

The project has received funding from the European Union‘s Horizon 2020 research and innovation programme under Grant Agreement n° 653851.

Results

Prototype development of a new energy optimising climate control system for electric vehicles based on the thermoelectric Peltier effect.

In this video our Lead Mechanical Engineer, Tim Perry, explains the various features of a working prototype developed and showcased at the Jospel project meeting in May 2017.
