Tesla engineer warns against using extension cords at Superchargers

[PreservedSwine]

“UL Certified” is meaningless. It must be listed to a standard and be given a listing number.

I could be wrong, and it’s been a while since I’ve dealt with UL, but I thought receiving UL certification required a listing number be given with the certificate?

At any rate, I see the extension plug being exponentially more dangerous than the plug alone. (Not saying I’m against them, a .0000001 fail rate might increase to a whopping .000001, an increase of 10x yet still insignificant).

That’s a metric crapload of current being delivered, and under optimal conditions no one would be using any plug-in connectors of any kind. But as the plugs are a necessity, the temps are monitored with the cable and harness system in place. With the extension cable, you not only lose temp monitoring, you’re also adding (2) more weak point of contacts.
The fail rate will still be infinitesimally small, but the failures that manifest could be catastrophic. How many are “acceptable” for the sake of convenience? Beats me, I’ll leave that for the actuaries. I suspect time will tell.

If A2Z sells it, I’ll buy it. My experience with their products is 10000% and their support is so good.

I trust they are taking safety seriously. Their interviews with @tommolog, their CEO and their contract engineer about the NACs to CCS adapter were impressive. Fanboy? Yeah maybe, but I think whatever they sell will be safe.

Hopefully all the negativity results in the price lowering for this.

Even if I thought it was safe (I don’t) I wouldn’t spend any money on it. I haven’t had any problem charging at Superchargers with the short cables. If Tesla doesn’t want me to take up two spaces they can add longer cables.
