Hi, we had some studies on the portable charger cords that we have here in Malaysia which is based on British Plugs standards of 240V 13Amp and we found that the Nissan Leaf UK specs charger cord is a 240V 10Amp, Delphi is 240V 13Amp. Chevy Volt needs 120V 15Amp and 240V 20Amp. Our charging poles use 13Amp 240V sockets. Technically Volt will not accept these Amperage but we are puzzled that it used to work before using the Delphi 240V 13Amp unit. Can you tell me how GM solved your problem? currently we can not charge our Car.
