New vehicles from the field of electric mobility will put our future electricity networks to the test. In this project, the conversion of an entire taxiflot to electric vehicles, including charging infrastructure, was analyzed in more detail.

The ZENEM project has set the goal, to integrate future electrical users such as electro mobility (which due to high penetration rates cause high power densities) into the existing electricity network and on the basis of a special case, a taxi fleet, which is characterised by the high concentration at these locations, to investigate the effects of E-taxis on the distribution network.

Project objectives

Future electricity networks are confronted with new challenges. Additionally responsible for example are consumers of electric mobility vehicles. They have a higher efficiency and thus reduce greenhouse gas emissions. Without electrification of the powertrain the ambitious climate targets in the traffic sector cannot be achieved and the Austrian dependency on oil imports is therefore also not minimised.

In this project the examining of the effects of a high penetration of electric vehicles on the electricity network, the conversion of a whole taxi fleet to electric vehicles along with needed charging infrastructure, is closely analysed. The resulting general project objectives:

• Determination of the energy needs of future E-taxi fleets using historical GPS data
• Assessment of existing electrical loads and verification based on measurements
• Formation of scenarios taking into account the feasibility of mobility
• Synthesis of measures for the integration of the E-taxi fleet into the existing electricity network
• Impact analysis of the E-taxi fleet on selected network sections
• Analysis of economic and ecological aspects and conditions
