By Reuters Staff (Recasts, adds Google, Enel comments) MILAN, May 13 (Reuters) - Italy’s competition regulator has fined Google 102 million euros ($123 million) for excluding an e-mobility app developed by Enel from the U.S. tech giant’s Android system. For more than two years, Google has not allowed Enel’s JuicePass to operate on Android Auto - a system that allows apps to be used safely in cars - unfairly curtailing its use while favouring Google Maps, the regulator said on Thursday. “The contested behaviour can influence the development of e-mobility in a crucial phase ... with possible negative spill-over effects on the growth of electric vehicles (EV),” it said.
