The testing of the eDrive energy management system is also of particular importance. Engineers analyse the way in which the extreme sub-zero temperatures affect how the energy storage system recharges, how electricity is transferred to the electric motor, how the electrical system is supplied with energy and how the heating and air condition systems respond.
The power transmission and suspension regulation systems are also tested far beyond what is standard in day-to-day traffic conditions. On closed-off, ice-covered surfaces, electronic regulation can already be provoked at low driving speeds. For the engineers this means that they can, for example, analyse the interaction of the all-wheel-drive system, which was especially developed for the electric drive, and Dynamic Stability Control (DSC). They can then continuously optimise the processes under reproducible conditions.
