Blue gunk in charging port

[studiomanuel]

I went to unplug my Grizzl-e charger this morning and found a blue substance on the connectors.
I’m pretty sure everything was dry when I plugged it in last night night. I charged from 20% to 80%

Do I need to take it to the dealer, return the Grizzl-e, or can I just contact cleaner this off?

2024 purchased in December and the Grizzl-e is new as well.

Corrosion on my plug? : r/electricvehicles

Oh, wow!

Clean it properly by all means.

However, If you’re not a qualified EV technician I’d take it in ASAP before you charge again and have it cleaned professionally and the electrical contacts checked.

Same for the charge point where this happened.

It’s the material of the charge plug and/or charge port which is oxidising and degrading.

There is a risk of resistive heating and fire if the contact between the plug and port are not good when you next come to charge.

You may remember stories of EVs stuck, welded to their charge points, this is why.

That is corrosion for sure!!

Yikes! looks like the corrosion one would see if you left batteries in something like a flashlight for several years and they leaked! I'll be checking my port more often. My charger is in the garage and out of the weather but I've no doubt Michigan road salt dust sneaks into every orifice possible.

Holy cow, yes that corrosion all needs to be removed before you use it again! See: https://www.macheforum.com/site/threads/how-to-clean-and-inspect-your-charge-port.29901/

It looks like the J1772 plug is missing the weatherproof gasket? That or else you are not storing the J1772 properly when it's not in use (the end should be covered so water/snow can't get in it). Do not store the unused plug out in the open (use something like this).

Based on the amount of corrosion I'm seeing, I would strongly recommend you just replace the J1772 cable entirely to ensure you have good clean connections. Maybe send that photo to Grizzl-E and see if they will warranty it. The main AC contacts look trashed. You don't want that to cause further damage to your charge port.

Is there a chance somebody sprayed something into the J1772 cable to vandalize it? Could also just be from the road salt, I see it all over the connector.

Thanks for the replies everybody! The cable does have its gasket and I put it on when not in use. I’ll see if I can get a new one under warranty.

I’m out in Long Beach, California so it’s been pretty dry.

So is the salt residue from the ocean then?

It looks like the corrosion is on the handle, which transferred to the car. I live not far from you in OC and have never seen anything like that. If it were my car, I would clean everything up and keep a close eye on it. The handle does look pretty bad though?

An update from Grizzl-e


Thank you for contacting our Technical Support Department. We are sorry to see you are experiencing this.
To get rid of this simply apply some dielectric grease that can be bought at local automotive and hardware stores such as Home Depot for instance.

Please let me know if it worked for you and if you need any further assistance I'd be happy to help you.

…….and if it didn’t work and the contacts are severely affected by the oxidation call your local fire department??‍

This thread had me look really closely at both my charge port pins and my L2 connector on my Emporium.

I am 1 week away from 1 year of use with the 2023.5 Mach-E.

I discovered a flattened carcass, of what appears to be a ladybug, deep down inside the L2 connector, but between the pin-stalks. So no bearing on functionality, although a bit of regret for one of my favorite insects that I meant no harm. ?

With further scrutiny I DID notice the tiniest portion of the same blue hue, but very dry, on one of the data pins. If I didn't know what I was looking for, I might have missed it. So whatever it is that creates blue corrosive(?) material from electrical conductors, I had some on what is otherwise very clean and perfectly functioning L2 charger components.

It’s copper oxide, the product of the oxidation process of copper affected by the introduction of moisture.

I'd expect something more than contact with the air to cause this... Is the white residue on the plug salt?

Exposure to water and air is all you need for the oxidation process and I reckon what appears white on end of pin is reflection. There is light coloured powdery residue around the plug which is a separate thing to the oxidation of the copper content of the pins and connections.
