Lubricating the EVSE plug

Tue Mar 28, 2017 2:25 pm

I've had my 2016 Leaf SL with an OpenEVSE for more than a year now and one thing I've been considering is lubricating the J1772 plug as I find it takes some force to fully seat or remove it.

Do others find this seems to require more force than should be necessary, Maybe the plastic used for my particular OpenEVSE plug happens to bind with the type of plastic the Leaf uses. Or maybe this force is just what is needed for the electrical contacts (but I doubt it).

It would make a difficult-to-clean mess if this didn't help any, so I wanted to ask if anyone has tried lubricating their plug (I only charge at home, so am not concerned about messing up any public chargers). My first thought would be to try white lithium grease on both the inside and outside of the big 1½" shroud around all the pins.

You'd want a silicone lubricant designed for both plastics and low temperatures.

Dry, silicone spray lubricant maybe. Definitely nothing conductive. Most dielectric greases would attract dirt though, which would probably make things worse rather than better.

Check the Jplug to see if the rubber O ring is out of place.

I use a small amount of non-conductive silicone dielectric grease once in a while on the plastic and pins of the J1772 cable of my primary EVSE (since it gets used nearly every day and has been used since 2011). About a year and a half after getting the 2015 I started to notice it was getting harder to plug in the AeroVironment EVSE so I checked the O-ring and made sure the plug was clean before I greased it. Just a small amount of grease every few months is sufficient. I also use a very small amount of silicone oil on the hinge and pivot points for the charge port door which really helps to make it easy to close. The silicone grease and silicone oil do not collect nearly as much dirt as petroleum oil and grease (and silicone is safe for plastic).

The reason your EVSE plug requires force to insert is because OpenEvse supplies Duosida plugs with their kits. Those plugs use power sockets that apply way too much pressure on the pins inside the car's charge port. I investigated this problem here: viewtopic.php?f=26&t=22692&start=30#p473786

I also have an OpenEVSE and I applied some silicone dielectric grease to the outer mating ring of my J1772 plug just this past weekend.

It did not make insertion or removal any smoother or less forceful.

Now that I saw AntronX's post, I'm not surprised, but at the time I didn't realize the issue was with the pins themselves. I'll probably be disassembling my handle this weekend to remove the springs from the sockets and hopefully that will solve it.

I have tried spraying silicone on the sides of the plug, with no improvement. Somehow it seems that the resistance is how the small contact tubes align with each other?? I also have to work at putting the plug back in the charger's little evse holder plug.

Yes, it is hard to figure out because you really cant get into those small areas. I had considered sanding the outside of the plug handle in case the seams of the plastic casting were not smooth..

The important thing is that it still works, and you get used to pushing it in a bit harder.

Hey! I discovered my J1772 problem. Today, inside the charge handle plug< I discovered a destroyed green gasket that was the culprit. I removed it, and it connects smooth as glass... I think that the gasket is to keep water out while you are charging....

I also found this link on ebay, which was selling replacements, but I haven't been able to find a current seller

here is the link and picture of the replacement gasket I need:

That's a common problem. I didn't mention it because someone else already had, and because I had a tight-fitting J-1772 handle until recently, with a good gasket.
