Taycan slower than other 800V

[violuma]

I was just side by side with a Rivian yesterday that charged from 25% to 100% in less than 30 minutes paying for the charge and my Taycan with the base battery pack took 30 minutes to go from 65% to 90% on the free 30 minute rate.

I think those boldface bits might be relevant, because it would seem to make sense that charging speeds slow down as SoC rises.

Out of morbid curiosity, what are your thoughts on the moon landings and the shape of the earth?

Humor aside, as well as institutional intent, the first analogy is quite apt: NASA would be just as incapable of covering up a faked mood landing as EA is incapable of varying charging speeds via payment status.
(Seriously, EA can't even impose idle fees, or prevent daisy-chaining of free 30-minute sessions. Yes, EA has been trying on the former and sending out after-the-fast emails on the latter. But EA consistently throttling charging speeds for freebie sessions, really, anyone think EA is capable of doing that?)

So when is the OP going to chime in on whether this indeed was a CPE250 unit?
I feel like ChargePoint just doesn't garner the attention it deserves for such a lousy charging network.
Sure EA is the unsurpassed winner, but plenty of dishonorable mention prizes to go around.
Especially if we want to combine DCFC and L2, given the prevalence of CT4021/4025 units -- at one of which my Taycan is charging right now at 5.3kW (to be halved if anyone else shows up, thereby devolving to closer to L1 speed). Granted, this is free, but these units just give public charging such a bad name.
(All of these are owned not by ChargePoint but the site owner, which also sets the pricing, yet also has to pay ChargePoint a subscription fee, all of which makes for an interesting business model.)

My car tends to charge much faster than or at least at similar rates to the other vehicles around me when using EA free charging. I typically get blazing fast speeds (260+) when I charge via P&C on road trips. I doubt your data will show any consistent pattern but I’m likely not long forward to hearing about your findings. I hope I didn’t offend you with my conspiracy theory joke, that was not my intention.

No offense taken. I just am frustrated with never getting above 140kwh on 350kwh fast chargers for the last 7 months since I bought my Taycan but have seen others get over 200.
I can see why the charge rate would be lower when all chargers are being used but have had this sneaking suspicion that maybe their is a difference in EA’s business perspective that they would want to prioritize getting people who are paying in & out as quickly as possible vs people who are on the free plan.
Hopefully my test to do back to back to back charging sessions using my free account, then my paid EA account & then my free account again when my SOC is less than 50%. I will try this theory out late at night when the EA chargers are mostly available and again when all EA chargers are occupied. That should tell me one way or another since I’ve already made sure I charged with varying battery temperatures from 85 degrees to 96 degrees and saw no noticeable change in charge rate.
I even saw a Ford Lightning & a Hummer EV come in to my EA station in Newport Beach, CA after me and leave before me but I have no idea if they were just topping off or they charged their batteries fully.
I will let everyone know what I find out but I can’t imagine if I had the bigger battery in my Taycan & it would take more than an hour to charge it from below 10% when I do the battery calibration sequence to balance the cells which I do once every few months and appears to improve my overall range by almost 10%.

I guess I’ll have something to say on this the next time I go to an EA charging station. My three years of free charging ended at the end of June.

I’ll give it a try soon and let you know what I learn.

It will be interesting to see what you experience before and after.

Yes, just a software setting, ATT throttles back my unlimited data plan as soon as I get above a certain level of data use but at least I get a message when I’m approaching the point where they limit my data speed. I then get a call from my ATT business sales person to offer me a more expensive plan to allow for a higher data usage level before they throttle me back.

 

[Jonathan S.]

With EA, just a software setting is a major endeavor.

Australia here! My 2023 Taycan GTS charging at a public 125 kW DC charger at only 80kW. Another 800V architecture EV pulls up 15 minutes later and starts charging. It gets 80kW and mine drops to 40kW. We are both at similar levels of charge. One a BYD one a Polestar. Why do they get a faster charge? Why is mine only achieving 80kW anyway? Do I have a charger software problem? Any ideas gratefully received before I discuss with dealer.

have you verified that the charger isn't on "single mode" that mode splits the power in the charger, happened to me.

I’d bet EA keeps the charge rate low for all vehicles on the “free 30 minute charging for 3 years” plan.

I have 11 months left of three years of free 30-minute charging with EA. A couple of days ago I waited on a Ford Mustang Mach-e charging at 35 kW at 23% SOC on a 150 kW EA charger. The poor driver disconnected and drove off in frustration. I plugged my 2022 RWD into the same charger at 21% SOC and got 160 kW, which quickly settled down to 140 kW.

I just wish that would happen more often.

Damn, I never realised the moon was flat. Everything makes sense now.

Wow! That’s terrible. Maybe the EA chargers are simply not reliable as fast chargers. Since there are so few they never get a break. Like I said earlier, when I stop in Baker, CA with a Tesla rental there are 120 chargers and most are empty unless it’s a holiday weekend but the 12 EA chargers have line of at least 6 to 10 cars waiting on a normal day and 20 or more cars on a holiday weekend. The Tesla charging infrastructure is so much better than EA of course because they had a big head start but Elon Musk not only makes batteries but also solar panels and home lithium ion panels which none of the car manufacturers have. Porsche/Audi buys their batteries from LG, they have no solar panel products and no home lithium ion battery storage systems like the Tesla PowerWall. Tesla has a big advantage in Baker, CA. Not only are the 120 chargers from Tesla but so are the solar panels producing the power for all those chargers at least during the peak hours of sun. Whatever he doesn’t sell to EV drivers he sells back to the grid at the same rate.
The 12 EA chargers at the same Baker, CA location are covered with solar panels but I’d bet they made a deal with Tesla to use Tesla solar panels above the EA chargers or more likely Tesla leases the space above the EA chargers for their overall increased capacity to sell to EV drivers or back to the grid. I will check to see how the panels are wired next time I go to the EA in Baker…

Thank you very much for your help. some interesting ideas. Bottom line, how do you know on a 2023 Taycan GTS it is charging as fast as it should ie that there is no problem with the vehicles charging software and hardware?

What was your state of charge? It matters!!!!

The rate slows the closer to full it gets.

For a best case charge show up with 20 percent or less AND select the charger in the GPS so it will warm the battery.

I had what I think is a record for me today.

 

[OzzieT]

@DerekS that is amazing charging speed. A record on this forum possibly as well? That sort of performance appears to be a distant dream in Australia, outside of the Tesla network (which is still mostly locked for Tesla).
