Electric vehicle charging infrastructure in Uppsala : Current state and potential

Abstract: The aim of this study is to make an inventory of the charging infrastructure for electric vehicles in Uppsala municipality. The 89 public charging outlets in the area has been compiled according to their outlet type and power output and located in a map. The charging stations are deployed in the centre of Uppsala and in the outskirts, mainly the eastern parts. The total installed power of the charging outlets in Uppsala is 1036 kW. Potential energy use of the charging outlets has been calculated with several different coverage ratios. The result of potential energy use in a year with 100% coverage ratio is approximately 9 GWh which as an example equals 70% of Ångström Laboratory's electric energy use or 0.6% of Uppsala municipality's over a year. With data from 16 specific charging stations in Uppsala and other cities, coverage estimates have been done with a result between less than 1% up to 13%. It is concluded in this study that further measurements of the charging outlets' electric energy consumption are necessary in order to calculate coverage ratios and coordinate an expansion of the charging infrastructure.
