Optimisation of the underhood flow for improving energy efficiency of BEVs

Energy efficient vehicles are essential for a future sustainable society, and today, all car manufacturers work on extending the driving range on their Battery Electrical Vehicles (BEVs) through efficient energy management. Since the available energy in a BEV is limited, it is crucial to minimize all energy losses.

To achieve this, a multidisciplinary approach where both thermal management of systems and components need to be evaluated and optimized without negatively affecting the aerodynamic drag, which is directly related to the driving range of the vehicle.

To approach the issue, numerical simulations, physical measurements, and optimization algorithms will be used and improved to allow for application in product development.

The project will strengthen the Swedish vehicle industry position in the international market, and it is expected to result in an increased range extension of 0.5-1.0 % on the test vehicle in cruising conditions.
