Added Charging view: In case the charger is connected to the OSTC a new menu will be shown in the customer view section. The new view shows a charging current indicator, the current charge percentage and an estimation how long the completion of the charging cycle will take (hour window). Some multi language text definitions have been added to support the new view.
