QUIET project : Qualifying and implementing a user-centric designed and efficient electric vehicle


Summer 2019

Current activities in the field of vehicle electrification offer a great potential for contributing to climate change mitigation by reducing anthropogenic CO2 emissions. Beyond the environmental strain, there is also an economic one. In 2017 the automotive sector accounted for 4% of EU's GDP employing approximately 12 million people in the manufacturing, sales, maintenance, and transport domain.

It is therefore crucial for the European automotive industry to exploit not only the environmental benefits, but also the business opportunities which come from the transition from conventional fuel powered to electrified vehicles. In order to capture these opportunities, electric vehicles must deliver better performance at a lower price, overcoming the constraints that are currently limiting their mass-market uptake. One major constraint is the limited driving range compared to conventional vehicles due to the limited battery capacity and high cost of the electric energy storage systems.

The QUIET project aims at developing an improved and energy efficient electric vehicle with increased driving range under real-world driving conditions. This is achieved by exploiting the synergies of a technology portfolio in the areas of user-centric design with enhanced passenger comfort and safety, lightweight materials with enhanced thermal insulation properties, and an optimised vehicle energy management.

The developed technologies will be integrated and qualified in a Honda B-segment electric vehicle validator. Among these, a novel refrigerant for cooling, combined with an energy-saving heat pump operation for heating, advanced thermal storages based on phase change materials, powerfilms for infrared radiative heating, and materials for enhanced thermal insulation of the cabin will be investigated. Further focus is put on lightweight glasses and composites for windows and the chassis, as well as light metal-aluminium or magnesium seat components. Optimised energy management strategies, such as pre-conditioning and zonal cooling/heating in the passenger cabin as well as user-centric designed cooling/heating modules will further enhance the thermal performance of the vehicle. These strategies will be seamlessly implemented in an intelligent vehicle control unit enhanced by a novel Human Machine Interface, which, beyond being intuitive and user friendly, will also consider diverse users’ needs, accounting for gender and ageing society aspects.

The objective of the QUIET project is to reduce the energy needed for cooling and heating the cabin of an electric vehicle under different driving conditions, by at least 30% compared to the Honda baseline vehicle. Additionally, a weight reduction of about 20% of vehicle components (e.g. doors, windshields, seats, heating and air conditioning) is addressed. These efforts will finally lead to a minimum of 25% driving range increase under both hot (+40°C) and cold (-10°C) weather conditions

The QUIET project consortium involves a collaboration of 13 multi-disciplinary and complementary partners from industry and research originating from 6 different countries. All public deliverables and further information about QUIET are available at https://www.quiet-project.eu/.
