Don't forget China. They took the European charge Mennekes connector, swapped the polarity of the pins, and then declared it "promoting indigenous innovation".

Don't forget China. They took the European charge Mennekes connector, swapped the polarity of the pins, and then declared it "promoting indigenous innovation". China also has a DC charging plug that is completely different from everything else. Now every Chinese car needs TWO plugs. The dream of a world wide standard is impossible to achieve, since setting differing standards is much easier than imposing duties. It is similar to why North American cars seldom have yellow turn signals at the rear ... FMVSS vs EU-Directive and the likes.
