Glazing in Electric vehicles

Electromobility is seen as one of the greatest opportunities to radically improve the environmental footprint of Europe's transport sector. In this area as well, advanced glazing solutions have an important role to play.

Batteries in EV applications are a significant portion of the final vehicle mass and cost. Thus the current research and development in technologies for electric vehicles (EVs) is seeking ways to further reduce vehicle weight while limiting higher sound propagation, by looking at smart materials. Innovative lighter glass materials are under development to support that trend.

In addition, just as the fuel economy of a petrol car can vary according to the temperature and weather conditions, the range of an electric car is affected by extreme weather conditions. For instance, TÜV SÜD found that in winter, the range of an EV can be reduced by as much as 50%, due to both the poorer performance of batteries under cold conditions and the need to heat the vehicle cabin. In hot summer days, the range can be cut by 30%, mostly due to the energy needed to air-condition the vehicle.

Given the impact of glazing on limiting the need to heat or cool vehicle cabins, the driving range of electric cars can be improved by way of advanced glazing solutions. To further increase the driving range of EVs, the integration of photovoltaic cells into the glass components of cars may also be just a few steps away.

Given the clear benefits of advanced glazing solutions, notably in terms of fuel consumption and extended range of electric vehicles, Glass for Europe believes that standards and norm on fuel consumption, CO2 emissions and ranges of electric vehicles should consider all real-life conditions of vehicles and not only engine characteristics.
