Addressing the different needs for charging infrastructure: An analysis of some criteria for charging infrastructure set-up

Electric mobility is an important means to decarbonise the transport sector. Especially in cities, the use of zero emission vehicles like electric vehicles is favourable, as emissions of conventional cars cause severe air pollution. Besides CO2, the most important emissions are nitric oxides, particular matter and noise. Given the trend of urbanization, the problem of air pollution in large cities will rather grow than diminish. Although electric vehicles are an infrastructure-dependent technology, one important advantage of plug-in electric vehicles (EV) compared to hydrogen-powered vehicles is the possibility to use the existing electricity infrastructure in households for charging. While additional public charging infrastructure is also needed for interim charging or overnight-charging for the so called "on-street parkers" without own garage, the majority of vehicles could be operated as EVs without additional public charging infrastructure. However, public charging infra-structure is an important component for the large-scale diffusion of electric vehicles and political action seems necessary since no business models are presently available
