摘要

Today, most research on electric vehicles is focussed on urban or metropolitan area traffic.rnHowever, a considerable number of people in Europe live in mixed urban-regional areas. Inrnthese areas, the demand for full electric vehicles is growing rapidly. Therefore, HeilbronnrnUniversity has launched a research project to identify the specific needs of individual andrncommuter traffic for electric car operation in urban-regional areas. Furthermore, strategies forrnmoderate electrical energy consumption and range extending are to be identified.rnSince August 2010, a plug-in battery-powered automobile has been available as a research carrnat the Automotive Systems Engineering research department. This car is a 4-seated modifiedrnconventional internal combustion engine vehicle now powered by 26 lithium-based batteries,rneach with a capacity of 160 Ah and a voltage of 3,2 V. The car has been supplemented withrnadditional equipment for the measurement and storage of state variables like motor current,rnregenerative braking current or vehicle speed, for example driven by an electric motor with arnpermanent power of 15 and a peak power of 26 kW, a maximum speed of 120 km/h and anrnoperation range up to 130 km is possible.rnThe paper and the presentation reports first results of the electric car operation focussed onrncommuter traffic. Here, different commuter traffic profiles are determined ranging from arncommuting distance of 5 up to 50 km including urban, highway and regional trafficrnconditions. By parallel GPS position location and recording, any elevation influence onrnenergy consumption is recorded. Also, the climate influence on energy consumption isrnanalyzed. An additional hilly traffic profile takes a slightly montainous landscape intornaccount. For all investigations, the energy regeneration balance by braking is analyzed,rnevaluated and discussed.
