- Testing a type 2 EV charging extension cable - are they a good idea, are they safe, and is this one any good?
Thanks to MCEV KELN for sending me the cable to try! Subscribe by 1st November and if youre based in the UK you could win the cable!

Note - I was sent the product for free to try out but this is an honest review! Other cables are available 😁
I will pick a subscriber at random on 1st Nov and as long as they are UK based they will win the cable. If they aren’t uk based I will pick another subscriber at random. Cheers!
Really good information in the video. Good to know that the extension cable mirrors the original charging cable capability.
Glad it was helpful!
I was slightly disappointed if I’m honest, I was hoping to overload the 16A cable to see what happens 😆
I was quite lucky, when I picked up my nearly new Kona EV there was no charging lead in there, just a granny lead. The salesman rushed around and brought me a nice new lead in a Hyundai bag and it’s a quite long hefty cable. I know, the car can only AC charge at 7.5kw. I had wondered if you could add leads together as my daughters Volvo came with a much shorter thinner lead that means she has to park much further up the side of the house to charge. Now I know
You tested slowly pulling apart the cable-to-cable connection under load. Another test for quickly pulling the plug and socket apart, as if someone tripped over a cable or caught it in some sort of machinery, perhaps? That would give the car's on-board charger much less time to shut down before the current-carrying pins disconnect.
Good idea
Useful. Thanks. 👍
very informative thank you
22kw ac should be the standard on all ev !!!! The zoe was on another level ❤, sadly is not on the new market anymore 😔
It is great to go to a workshop where they have 22kw charging, even arriving empty the car is full and ready to go before I am!
Would be nice to see a spring cap and a manual release cable lock on the socket end.
Nice idea.
Each end of a 'normal' cable has a resistor to tell both the car and the charger the maximum charge rate (220 ohm for 32A, 680 ohm for 16A), so if it were possible to extend two differently rated 'normal' cables, the car would charge at the lowest rate. Unlike a 'normal' cable, this extension connects PP down the cable, so it reports whatever is plugged into it.
I have modified the plug on my tethered cable with a switch to provide 3 different resistances to allow the car to charge at 13A, 20A or 32A, which is very useful for maximising solar power to the car. The car tells the charger (via CP) the maximum rate it can handle.
Hi as the resistor is between pp and earth if you were able to daisy chain cables successfully wouldn’t those resistors end up in parallel resulting in a lower overall resistance?
@@garyc4450 No, because on a 'normal' cable, the resistor is only in the plug, and does not connect to the other end.
Yes the resistor is in the plug, but it’s connected between pp and earth so whether it’s in one end or the other doesn’t matter, there is 220ohm let’s say between pp and earth, that’s detectable at each end of the cable. If you could daisy chain another cable which has 220ohm between pp and earth you’d then have 110ohm between pp and earth surely?
@@garyc4450 PP does NOT connect down the cable. so the resistor is the only connection to PP on the plug at one end and there's another resistor to PP at the other end.
You can prove this by connecting a multimeter to measure resistance between PP at each end of the cable; there is no connection. Actually you'll measure both resistors in series, via PE, so expect to see 440 ohm on a 32A cable and 1360 ohm on a 16A cable.
Great video
Thanks!
Please can you measure the resistance of the extension and work out how much extra energy is lost as a result of using the extension cable?
Hi it’s around 0.1ohms. The extension cable is made of 6mm2 wire, if it consumed much energy at all it would effectively be a heater and would overheat from a long charge. The extra energy consumed is negligible. Thanks.
@@garyc4450 thanks - my regular charger lead is warm to the touch after a full night of charging. Good to hear the resistance is so low.
how water proof is the plug when lying on the ground ? can you submerge it without any danger ?
I wouldn’t want to submerge it on water, it’s certainly not that waterproof! Looks rain and splashproof. Cheers
Maybe that’s why there is a wide collar around the input end, it would keep it further off the floor.
@@silverghini2629 The wide collar is because that socket is designed to fit to a vehicle or other closed box, rather than on the end of a cable. Hence the holes in the collar for fixing screws. It's not designed to hold the socket off the floor, although that's a slight advantage.
