EV Charging cables.

[kentishdriver]

I can't see charging cables covered elsewhere. I have an XC(90) Recharge with the standard 7.0m 3 pin plug/Type2 cable. I'm looking to get an external 3pin socket put in at work, but for the practicable socket positions, the 7.0m cable is not quite long enough. Does anyone know of longer cables or suitable extensions that can be used. Screwfix do a 10.0m cable, with a built in charger/controller. Also there are on the market 5.0m Type 2/Type 2 extension cables. Will they work or will the Volvo car, or controller, sense them and not charge. Help or suggestions appreciated.

So from testing on my V60 any 13a extension will work but when I plugged in an RCD the Volvo granny plug just refused to draw any power. But you need to be careful about water ingress because although the Volvo charger is waterproof the plug on the end obviously is not.

For the first 3 months of ownership I wasn’t able to get a wall box fitted so used this constantly (pretty sure mine is 15m) rain or shine.

The only change I made was because the sockets are inside the garage (I snuck the cable under the door) was I got a £3 switched single gang and swapped it with the one supplied (inside the waterproof housing is a normal unswitched household socket).

I still use it when I’m away from home.

I got one from here - proper heavy duty ones you need. Not the rubbish you get from B&Q etc. I didn't need a waterproof socket so is a bit cheaper, but they do waterproof socket ones as well.

Yeah. I just use a three-pin extension cord, one with surge protection and my outlet in the garage is also protected by an RCD.

Works fine for me and never had a problem in charging.

Of course, you'll need more protection if the socket is outdoors (my extension socket takes it as far as the inside of the garage door).

Thanks for the above. Was trying to avoid a conventional extension lead, because of the various Volvo guidance saying extensions must not be used. The above look decent, and will probably buy one, not sure which one, and first test at home.

Frankly I wouldn’t hold any sway when it came to Volvo and charging cables - frankly they can’t get their software sorted let alone chargers.

My dealer tried to tell me the reason the car wouldn’t let go of the charger when it was cold (ie under freezing overnight) was because I was using a BMW branded cable. The amusement was it was a random cable in the boot for public chargers and it was a podpoint - ie the charger Volvo recommends.

I have a 15m extension lead from Tough Leads too. Used almost every day for more than a year now with no issues. In fact on one occasion I plugged the Volvo lead into a friends outdoor socket and it refused to charge but when plugged into the same socket via the extension lead it worked fine!
I wouldn't pay too much attention to what Volvo say about not using extension leads so long as you buy a suitable unit - they just need to cover themselves against people who would go and buy the cheapest extension lead with the thinnest cable core and leave it out in the pouring rain with no protection.

Bear in mind that if you want to use an extension lead on a reel, then you'd need to unwind it fully as the amperage drops when the lead is coiled up.

Hi

Bear in mind that if you want to use an extension lead on a reel, then you'd need to unwind it fully as the amperage drops when the lead is coiled up.

And more importantly, if still wound up or partially wound up, when being used, the reel could overheat and catch fire

That's incorrect, the amperage is dependent on the load. The reason coiled extension reels heat up is that there is a loss in the cable, causing it to heat. When the lead is uncoiled the heat dissipates into the air. However, when the coil is left on its drum, and the load is significant, the heat loss is contained within the coiled cable.
What is often forgotten is that there is always a loss in electric transmission, even with the ubiquitous power lines. It is minimised by using larger conductors. Hence the recommendation to use heavy duty extension leads, not the cheap, lower capacity B&Q and similar ones.
