Stupid charging question: L2 cable uncoiling?

[condition5]

Home L2 charger is a Ford Charge Station Pro (25' cord) hardwired in a garage.

Parked head in, I have to fully extend the charging cable to reach the port.

Backing in, the port and charger are about 3 feet apart...

So, I don't have to uncoil when backed in.

But should I?

I don’t. No issues for the past 3 years.

Ha, can't help but notice your picture on the floor looks a lot like Brent Spiner!

No

The electricity doesn't care.

And from a safety standpoint, whatever is the least likely to get yanked/tripped over would be best.

The rule is use big loops (e.g. 4' tall) so you don't have more than about 3 sections of cable touching each other. If you do a bunch of small tight loops then it can be a problem.

That's so you know it's a Data cable on the hook.

The rule is use big loops (e.g. 4' tall) so you don't have more than about 3-4 sections of cable touching each other. If you do a bunch of small tight loops then it can be a problem.

That is a good point about tight loops, you certainly don't want to bend that cable too much because that could damage the wires by bending/kinking the wires inside. In general, I think the cable will basically tell you want it needs, by the fact that as you wrap it around it will want to be at a certain radius, just don't force it.

My ClipperCreek states this as well.

Since the FCSP cable is designed for 80A and your car won’t exceed 48A, electrically, it doesn’t matter. At rest, I have 3 loops on the unit and uncoil only 1 when I charge the car. If I need to charge the Lightning at 80A, I remove 2 loops which leaves no part of the cable in touch with it self. I need to do that in order to reach the truck anyway.

Curious as to the reason behind this? What problem does smaller loops cause? My Emporia makes no mention of this.

My guess would be potential cable overheating.

The cable needs airspace around it to cool itself. If you make it tight loops, the cable can overheat and melt because there is too much concentration of heat in a small area. It is also stressful on the cable to have a small bend radius.

Here’s an example:

lol...ok, I'm not so concerned charging at 16A's.... ?

Here’s an example:

Theoretically, tight windings can cause the buildup of an electromagnetic field. That’s how motor windings work. The field results in impedance that effectively acts like a longer cable and results in heat production. However, this won’t happen at all if you have a few loose coils.
