Charger Interface Fatigue?

[DanCoon]

I have just a quick question about fatigue on the charger interface.

I anticipate D/C charging 2 times per week and the most convenient location to me uses one of those pulleys like you see on gas station pumps to remove the slack out of the hose. The pully on this station produces a significant amount of tug on the charger interface on the MME, so much so that I see it shift several millimeters.

Do you think this will cause any trouble after a few years, or do you think Ford took this into account?

If there is a way to reduce the strain on the cable then that would be ideal of course.

The Ford software does a continuity and thermal check of those DC pins to make sure they have a good connection. It also does a weld check to guard against electrical arc damage. That is about the best that can be done on the car side. It is pretty hard to anticipate all the various DCFC station setups so you will have to use some common sense when possible.

Some stations have a boom arm that swings out and helps reduce the stress on that connector. I don't remember which, but I saw a photo of a few and it wasn't super obvious from that I remember. Maybe the machine that you frequent has a similar feature?

Get one of these and clamp it on the retractor cord after you extend it. I've used a bulldog clip on my shoulder belt for years to get a little slack in it.

That's a great idea. Thanks!
