The aim of the trial, funded by the German Federal Environment Ministry, is to optimize charging strategies and to make use of renewable sources of energy (i.e. water and wind) to power up the Mini Es. In order to support the ongoing field trial, a total of 50 plug-in vehicle charging stations have been installed in and around Berlin.
The Mini E field tests began in 2009 in the U.S., the UK and Germany. Subsequently, trials expanded into France, Japan and China. In the first phase, the Mini Es in Berlin have racked up a reported 310,686 miles and three out of every four of the drivers advocate the exclusive use of renewable energy sources for charging up electric vehicles in the future. Too bad that's not always feasible.
