LIBERA Series2.2LIBERA SERIESCONNECTORS FOR ELECTRIC VEHICLESGENERALElectric vehicles mean end of air pollution andimprovement of quality of life.Tomorrow's vehicles - electrically powered cars,motorcycles, bicycles with aided pedal stroke - arebecoming an increasing reality, also thanks toScame, a company that always believed thatdreams could become true.Facing this challenge, Scame designed newconnectors for vehicles and supply stations,enabling supply from specific columns or from thehome garage.The outcome is the LIBERA Series of adapters,plugs, movable and flush sockets, complying withthe evolution of the standards promoted by CIVES -the Italian Commission for Electric Road Vehicles -,which are becoming actual reference standards.Reference standardItalian Standard IEC ENV 50275-1IEC 69-2endorsing European Standard ENV 50275-1Conductive recharge of electric vehiclesPart 1 : GeneralNovember 1999Italian Standard IEC ENV 50275-2-1IEC 69-3endorsing European Standard ENV 50275-2-1Conductive recharge of electric vehiclesPart 2-1 : Connection of electric vehiclesNovember 1999Italian Standard IEC ENV 50275-22IEC 69-4endorsing European Standard ENV 50275-2-2Conductive recharge of electric vehiclesPart 2-2 : a.c Recharge stationsNovember 1999Italian Standard IEC ENV 50275-2-3IEC 69-5endorsing European Standard ENV 50275-2-3Conductive recharge of electric vehiclesPart 2-3 : d.c.

Depending upon the placewhere recharge columns will be installed, be theyprivate places with access allowed only toauthorized staff, or public places where access isallowed to everybody, the supply of electric powercould be or not subject to payment. This could bemade for instance by charging the amount of thepower withdrawn to the credit card, as it happenswith normal vehicles at fuel stations.According to draft European Standard ENV 50275,there are four different method to rechargeelectric vehicles, depending upon the type ofconnection chosen:Recharge method no. 1:Connection of the electric vehicle to the a.c. mains- mains side - by means of single-or three-phasestandard plugs and using the phase/s, the neutraland the protection conductor. Standard plugs,mains side, are those complying with therequirements of national and internationalstandards.Recharge method no. 2:Connection of the electric vehicle to the a.c. mains- mains side - by means of single-or three-phasestandard plugs using the phase/s, the neutral andthe protection conductor. with the addition ofcontrol functions between the electric vehicle andthe plug or the control box as specified at item 6.4.The control box shall be mounted on the cable at adistance of no more than 0.3 mt from the plug orfrom the EAVE.Recharge method no. 3:Direct connection of the electric vehicle to the a.c.mains by means of dedicated supply equipment,where the control functions specified at item 6.4are extended to the portion of equipmentpermanently connected to the a.c. mains.Recharge method no. 4:Indirect connection of the electric vehicle to thea.c. mains by means of an outboard batterycharger, where the control functions specified atitem 6.4 are extended to the portion of equipmentpermanently connected to the a.c. mains.The above mentioned standard indicates specificrequirements, which may be either compulsory oroptional, for each of the above recharge method.Italian manufacturers of electric vehicles decided notto use recharge method no. 1, because it does notprovide any control on the soundness of theprotection circuit before supplying power to thevehicles, which might result into safety problems forthe user. In view of this concern, the IEC hasrequested a special condition of use; as aconsequence, ENV 50275 specifies that rechargemethod no. 1 should not be used in Italy.Plugs andsocketsAdaptorsDomesticcablereelsLampholdersTV & PhonePlates anddevicesEnclosuresPlugs andsocketsInterlockedsocketsSwitchgearLight fittingsDistributionassembliesAdapter for domestic use.
