Potential of electric vehicles

Electric mobility is seen as an essential contribution to the future of mobility. Unclear, however, is the effect on sustainability - reduced use of primary energy - and ecology (greenhouse gas emissions) during real use by customers. The Institute therefore also addresses this issue and examines the advantages and disadvantages of battery electric vehicles in comparison with other conventional (modern petrol and diesel cars) and alternative powertrains (natural gas, hydrogen, hybrid solutions) as well as alternative, biogenic fuels.

According to customer requirements the potential estimation can not only take into account the actual operation but also the entire life cycle starting from energy production and ending with the recycling of the vehicle.

Concerning the vehicle, among other things can be determined the realizable driving distance, the energy demand differentiated according to individual consumers and in total and derived therefrom the energy costs.

This is made possible by modern measurement technology, as well as an institute's own dynamometer with air chamber (adjustable from -32 to +50 ° C), and a further 16 test rigs and the latest simulation equipment.

The relevant measurement technology for electric vehicles covers the high voltage range up to 1400 V and currents up to 3500 A, with a sample rate of up to 1 MSample.

With regard to voltage measurement, the measurement accuracy is <0.05% and concerning the current measurement <0.01%. In addition, programmable filters increase the quality of the analysis of premium-quality sensors. In terms of a complete vehicle analysis can additionally be detected pressures, temperatures, flow rates, pressure on the pedal, fuel consumption, mechanical torques, GPS location, speed and acceleration.

Consequently, very detailed results depending on various conditions could be worked out regarding the potential as well as advantages and disadvantages of this technology.
