Homemade 16amp control box

[chasingamy]

I own a hydropower plant where I have installed 16 amp wall outlets and I would like to make a simple (cheap) charge cable.
I bought an Outlander "gun" with a 7 meter cable and it has no plug to fit into the 16amp wall socket.
The cable end has the standard 3 wires for neutral, power and earth along with a small gauge control wire.
Does anyone know what kind of signal or voltage the car is looking for on the small gauge wire?

Very short answer: 12 volt 1 kHz Square wave with a duty cycle of 1% per 0.6 amps, 10% being the minimum. About 25 to 30% will do just fine. 1000 ohm between the 12 volt power source and the car.

That will work. But it is not safe.

Great, thank you Anko!

Can't always trust Wikipedia, but there's a quick explanation on there.

Just the thing for a safe DIY control box.

I did build my own. Info on wiki is okay. But I did add several safety measures
