The Impact of Charging Infrastructure on the Diffusion of Electromobility
Electromobility is considered one of the most promising technologies in order to decrease carbon dioxide emissions in road traffic. The issue ranks high on political agendas all over Europe as the comprehensive roll-out of public charging infrastructure will cost billions of Euros. However, the impact of charging infrastructure on the diffusion of electric cars is not clear. Consumers might be more likely to chose an electric car if they are exposed to the emergence of more and more electric cars in their respective neighborhood. The availability of public charging infrastructure might be less important as most cars are charged at home over night. Early consumers might have seeked the safety of a reliable charging infrastructure, while later followers are not motivated by even more charging stations but mainly by the peer effect. Hence, the effects might be non-linear and change severely over time.
Our study aims at estimating the extent to which an increasing availability of public charging infrastructure promotes consumers’ decisions to switch from conventional cars to electric vehicles. We make use of a German data set including monthly registrations of new cars at the zip code level between 2009 until recently and match it with the official registry of public charging stations. This allows us to keep track of the whole diffusion process starting with the very first electric cars in Germany. We then deploy dynamic panel approaches in order to identify the infrastructure effect on the number of new registrations of electric cars.
