You don't own a Tesla, do you?
It's not a trick to have to push the connector all the way in. Sometimes you think its in, but it isn't. After experiencing it a few times you get the feel of how it's heavier than the UMC or HPWC connector and needs a little more force.
How do you suggest Tesla design the contacts so they can't get dirty? They're outdoors in the elements. Sometimes people let the connector touch the ground.
No, I'm not a Tesla owner. But I am a prospective owner, so I'm trying to educate myself by reading testimonies from Tesla owners. And some of it is disconcerting. So that's why I posted and asked if my impression is wrong.
The OP said that he tried 4 different Superchargers and failed to get any of them to work. Granted, he's a new owner w/o experience, so it's not a huge red flag. But it's still not reassuring. Then another poster in this thread said that the trick to getting it to work it to push in the connector "quickly". This advice is far from intuitive or normal-sounding, so another worrying data point, IMO.
And regarding Supercharger performance...
I can't help but dwell on the fact that the Tesla connector is FAR smaller than the SAE CCS and CHAdeMO connectors. This stark difference always had me very perplexed.
At first I assumed that perhaps Tesla -- unencumbered by bureaucratic infighting between automakers in the SAE committee and freed from any requirements for backward compatibility -- were simply able to use their smarts to design a
better connector.
But now I wonder if maybe the reality is that Tesla made a poor design choice and erred on the side of a small/sleek/cool/sexy connector
at the expense of reliability and resilience that a beefier connector with larger pins and more contact area and better heat dissipation could provide.
Granted, this is all speculation, and we don't yet have real-world experiences with 100+kW CCS chargers to compare to. But it doesn't seem like an unreasonable thing to wonder/worry about, especially given Tesla reputation for pushing the envelope and making risky/questionable engineering decisions. (See FWD's and AP/ditching Mobileye.)
Also, note that I talked about pin/contactor "wear", and not simply pins getting dirty. The fact that Supercharger performance issues seem to be concentrated in high-usage areas seems to indicate a correlation with the frequency of use. But if the problem was due to contacts getting dirty, wouldn't intuitively expect a connector exposed to the elements in Kansas to stay any cleaner than a connector exposed to the elements in LA. Right?
Regardless, good design can also help keep a connector clean too, even if it's something as simple as cable management. But if it's mechanical wear that's to blame, that
could be attributed to insufficient connector design.
