Thanks for the polite comment. Why do you take offence when you ask for someone to name an available contact cleaner and they show one is available?

Like most electrical / electronic engineers, I keep a can of (cheap) switch / contact cleaner in the workshop. I use it to clean the contacts on my EV plugs and connectors, as well as other electrical tasks. Do you recommend squirting WD-40 lubricant into everyone's electrical equipment? If not, why recommend it for high power EV connectors? I did say there wasn't much risk and you did say that you took care to wipe it off. Others have just recommended squirting it in liberally.

You have said in a recent post that you admit when your a wrong. Well, practice what you preach please.

I have not remotely recommended that.

Why be so passive-aggressive as to put completely different words in my mouth just because you want to try to show me for being an arse?

Please quote to me the words you say are wrong that you cannot bring yourself to admit are correct.

WD-40 specialist contact cleaner. Shame that they are overloading the brand name.
I did not look at the advert, it was irrelevant to my point.

Now that I do, I would NEVER recommend using any such liquid in the manner illustrated in that advert. That's mad and unnecessary. What a mess.

Donald, I'm not trying to make you look like anything. Just bring out standard electrical engineering practice, which is not to put lubricants onto any electrical contacts. As you said above:

Reason I am proposing to do that (before anything else) is that if you use it a lot then a dirt layer builds on the pin (all the degraded metal) and it can eventually corrupt your communications connect.
Applying WD-40 lubricant regularly will tend to build up where you've not cleaned it away and attract dirt to the area over time, thereby increase the risk of corruption over the comms pins. Of course, if you keep them clean, as you do, that will be low risk. But why spray in a lubricant at all when there is a recognised, purpose-specific cleaner? I only posted the WD-40 offering as it came up first on a Google search, which I thought was a bit ironic.

And, as has been widely recommended in the forum, use a silicone grease to lubricate the actual connector. That won't spread onto the pins.

Sorry, it is as if you haven't read a word I put and made up whatever it is that is in your head of the image of me emptying a can of the stuff into a plug.

Try going back and reading why what you just wrote there is TOTALLY not what I put.

If you don't come back and say 'oh, OK', then I will oblige and point out your fallacious comments.

AFAIK it is the government collecting the data for ULEV purposes. Although the whole aim of the game with smart meters (and I suppose smart chargers) is to transfer everyone to a time of use tariff.
I understand why smart meters have to communicate data, but the actual charging unit? Is it just so the government can see if handing out all these grants were worth it, i.e. they gave the installer £500 or whatever to subsidise the installation but they want to see how much we use it to see if the government will ever make its money back? I guess it was a good idea in theory but seeing as they just ran up £300billion on coronavirus then I guess they need to focus more on the pounds and less on the pennies....

Read it again:

I didn't say that you had recommended squirting anything anywhere! I asked if you would recommend it, expecting you to say that you wouldn't.

I don't think we are saying anything wildly different, and don't see why you are making a big thing of it.

Your are saying that WD-40 does the job and should be cleaned off the contacts after being applied. I agreed, saying that the risk of doing so is low.

I'm saying that normal electrical engineering practice is not to use lubricants on contacts and that alternatives are available that I use.

That seems to me like a sensible exchange of views.

Sorry wrong thread!
Mine was almost out of warranty but what the guy told me was that rather than fix it he would swap for a new as my old one did not have the ability to communicate data. So if you have same generation as mine you might find they will swap it for a new one anyway. Of course, he didn't ask me to sign anything giving up my rights to ownership of my data, but there you go.

My Chargemaster 7KW home unit has also given up the ghost after a little over 2 years. I am having real problems getting them to do anything about it. I raised the problem with them 10 days ago and have not heard anything back.
On Monday I contacted them again by email, basically saying what is going on? I just got an email acknowledgement with no info in it.
This afternoon I just spoke with the customer services people who said they have no visibility of the home charger peoples schedule.

We are now a 2 EV family and beginning to run into issues with trying to keep enough power in two vehicles!!

Has anybody else experienced problems with BP Chargemaster fixing in-warranty but broken charging units?

Which is why an EVSE made up of discrete components has advantages such as:- repairable by any local sparky or competent DIYER, requires only readily available parts to repair, simple to diagnose any problems.

.. or for the cars themselves .. oh, errr .. OK ... hmmm....

I presume if the charger did not “communicate data” I wouldn’t be able to see the stats or set charging schedules on my phone?
