Extension cord for 40A Mobile Charging Cable Kit

[westhouse1983]

I have purchased the Lucid 40A Mobile Charging Cable Kit but will need to use it with an extension cord. I would be grateful for any advice on a suitable extension cord which can cope with the ampage. Thank you

I have used this one for 18 months or so. It has been solid.

you should be okay with Lectron or A2Z. Don't go with no name brands

This is not compatible with the Lucid Home charger.

Op said he has a mobile charger, so it would work, just on the other end.

Ahh yes I see that now. Classic case of tunnel vision here - I was unplugging my car from the LCHCS and was blinded by that thought.

Not an elegant solution for long term use on the opposite NEMA side but I suppose it would work.

To the OP an Important note… I am not an electrician and this is not advice on what is up to code for your area!

It's likely less dangerous to use a J1772 extension cord, and more dangerous to use a 240V extension cord, as the 240V cord would be lying on the ground and not protected by a GFCI. It would be extremely dangerous if the floor were to get wet. The J1772 extension cord would be protected by the GFCI circuitry within the mobile charger.

But neither is a good idea. If you are planning to keep an EV for a long period of time, it's best to hardwire a charging station closer to the correct location. Second best, move your 14-50 receptacle closer to the correct location and be sure to use an industrial-grade receptacle.

He’s not wrong. The “Lucid Home charger” he references is the LCHCS, which is the Lucid Connected Home Charging Station.

The one you’re referring to (and as later clarified in the thread) is the “40A Mobile Charging Connector” which is meant for “on the road” use, but which some people use at home.

I had my electrician install a plug near my garage door I can plug it in and run cable under garage door. Safer.

My thanks to all. I have ordered the Lucid Home Connected Home Charger which is scheduled to be sent out the week of the 15th of January (such as I have been informed by Lucid). In the interim, and as an alternative when I am away from home, I ordered and received the 40A Mobile Charging Connector. The problem is my closest 110v outlet, is approximately 20 feet from where I park my Lucid. I am therefore in need for a suitable extension cord. Furthermore, the question is do I plug in the extension cord to the 110v outside receptacle and then plug in the 40A Mobile Charging Connector onto the car, or do the reverse? Thank you again for your responses.

 

[westhouse1983]

As an edit to my message above, what I meant to say in the last sentence, was whether or not I needed to buy an actual J1772 extension not “do the reverse”. My apologies.

 

[DeaneG]

The mobile cable comes with a pretty long cord - it may reach just fine. Plug the cable into the 120V outlet, then the other end into the car.

Note: I'm not an electrician, but....

.... you just need a heavy duty entension cord for this application. Note that, even though you're using the '40A' charger, if you plug into a regular house outlet, i.e. 110v, you'd be drawing more like 12 amps, perhaps as high as 15 (I think a current draw is limited to 75% of the breaker, which is probably a 20 amp breaker).

So, find an extension cord that can handle a continuous 15 amp draw. I'd recommend a 10/3 (10 gauge, 3 wire) ultra heavy duty extension cord. Keep it as short as feasible, given your needs.

I would plug the charger in before connecting it to the car.

Here's some commentary from this forum posted in another thread (per Deanne G):
1. EV charging adapters have no idea how much current is safe to draw from house wiring, other than the current they are designed to operate at, or the setting they are set to. All 120V standard plug chargers will draw 12 amps. If there is something else on that same circuit drawing power elsewhere in the house, the breaker may trip.

2) You shouldn't use an extension cord for safety reasons. But if you do, use a 12-gauge outdoor-rated cord, not 14 gauge or some thin cord made for indoor use.

3) You'll get between 3mph and zero depending on the ambient temperature and if your car is awake, or locked and asleep.

4) After charging using the 120V receptacle for 10-15 minutes, unplug the cord from the receptacle and feel the temperature of the prongs on the plug you just pulled out. If they're hot, stop. An outlet's wiring and internal metal parts can loosen and deteriorate with time, leading to melting stuff and the chance of a fire. The plug's prongs should feel warm to the touch, not hot. This is why the strong recommendation is to hardwire a home charging station rather than using a 14-50 receptacle and plug.

I'd been thinking I might want to be able to plug into friends' 30A drier outlets using the Mobile charger w/30A plug option. For this, I'd been picturing getting a heavy-duty extension cord designed for 30A use (ie with the standard 30A male/female at its ends).

Any advice about this plan? Gauge of cord, being sure the connection between Mobile Charger male 30A and cord female 30A is shielded from moisture, etc.? Is 25' the longest I should consider, or could 50' be workable/safe? I could see limiting this to something like 2 hour sessions, to mimic the maximum time a drier might draw current; seem sensible, or unnecessary?

Also: the warm vs. hot distinction on the plugs, which I've seen mentioned several times.....any rule of thumb where that line is? (eg if can touch it for a full second, it's not "hot"? Or similar, name your time!)

Your friend's dryer plug would need to be the relatively modern, grounded 14-30 type rather than the old ungrounded 10-30.
"Warm vs hot" would be something that feels good to the touch rather than something that burns you.
Ideally, you'd upgrade your friend's dryer outlet to a commercial/industrial-spec 14-30 receptacle. These run $50-100.

... I could see limiting this to something like 2 hour sessions, to mimic the maximum time a drier might draw current; seem sensible, or unnecessary?...

It's worth noting that a clothes dryer doesn't pull 30 amps all the time. There is a thermostatic switch in the dryer that cycles on and off to regulate air temperature as the clothes dry. An EV, of course, pulls the maximum allowable current continuously.
