DC Fast Charging Station question?

[DBC]

He is wrong. Get him to place a bet with you. 10-80% can be done in about 40 minutes.

+1. Sucker bet time! Can go double or nothing on whether a Taycan using the highest power EA charger will charge faster than a Tesla on Tesla's highest power V3 superchargers.

Well it is called a Supercharger not a fast charger so it has to be faster, right?

A supercharger is just a charger with a cape.

I am being told by a fellow worker of mine who owns a Tesla that the DC fast charging stations doesn't charge the car up from 10%-80% in about 40minutes, it's more like 4 hours. Only the Tesla Supercharger network will charge that fast. Is this true.

Not true, that's the frog in a tesla well. Here's mine from yesterday on Electrify America charger from 26 to 80% in 30min.
Unless it's a fast charger this won't happen.

Some chargers at blink, evgo, chargepoint are only 50kwh max they take 2x longer than EA on an average.

I'm doing my first electrify America season right now, which is my first time at a charger over 50kW (and before you ask, I couldn't get the Ford Pass to work, but I'd been on the road 2 hours and had to pee so only gave it two tries before just using my credit card lol).

Started at 14% SOC. Been getting between 82-84kW so far and in 18 minutes I've gone from 14% to 42% and added 26kwh.

NO.

There are 2 basic types of chargers: AC and DC fast chargers

• AC charging uses a normal 120V circuit, or optionally a 240V circuit. 120VAC charging adds roughly 3 miles to the car in an hour, so 10%-80% would take days. With a 240VAC charger, it depends on the amperage available - A 40 Amp circuit is fast enough to charge the car from 10% to 80% in about 10 to 12 hours. Typically a 240VAC charging circuit is what is used at home and hotels because it is relatively cheap to install and charges overnight.
• DC Fast charging is equivalent to Tesla superchargers, and the power levels range from 50kw to 350kw, but the Mach E cannot draw more than 150kw. To go from 10% to 80% a 150kw DCFC will take about 40 to 45 minutes. A 50kw charger would probably take at most an hour and 20 minutes. Incidentally, Tesla has different charging levels as well - from 60kw to 250kw.

Note that all chargers, including Superchargers, are dependent on how much power they are supplied by the grid where they are installed. Many Superchargers share the same supply so when several Tesla’s are charging at once they degrade. I was recently told by an installer for both Superchargers and EA chargers that the EA 350’s typically have a separate supply from the 150s beside them. Key message - all chargers are highly dependent on location and thus are variable.

 

[NormF]

And EA 350’s are really max output of 270 which you will rarely see in real life even if your car could accept that much. I own a Taycan and I have yet to find a “350” in my area that outputs more than 135.

It just occurred to me your coworker could be referring to charging the Mach E to 100% at a DC charger. Like all EV's, once you get to 80% state of charge the charge rate drops - which is why for road tripping BEV's the prevailing wisdom is to charge to 60%-80% and move on. With the Mach E it drops more than most, so trying to charge to 100% from 80% can take an additional hour or so.

Still, your coworker is misinformed

It's not so much the grid as it is the architecture of the charging equipment. The V1 and V2 Tesla Superchargers share a single AC-to-DC cabinet per every two connectors. The 75kW urban and V3 superchargers get a cabinet per connector, as far as I recall

Tesla Superchargers only "degrade" if someone is on a similarly numbered post, so only one other car can possibly slow down your charging. If a 10 stall Supercharger location is full, and 3 cars leave, the other 7 cars don't get 30% more charging, 3 of the remaining cars will get approximately 50% more charging and the other 4 will stay the same (theoretically, in reality the charge curve of the car makes this sharing not just a direct split the entire time)

EA stations like you mention and the 75kW urban Superchargers and the V3 superchargers all have their own cabinets per post so there is no splitting of the power when a car shows up or leaves

Now that I know to initiate from FordPass (and not try to just plug-and-charge), I get moments of 135 kW.

I average 110 kW

Not true at all. I've burned through the free 250 kWh and then some on a 4,000 mile trip to FL and back. Using Electrify America 350 kW chargers I get 10-80% in right about 40 minutes, 20-80% in just over 30, and 60 miles of charge in about 10.5 minutes.

I get peaks of around 155-160 during the first minutes of charging at 350 kW chargers, peaks around 135 at 150 kW chargers.

 

[Blanked]

Just wait for the ludicrous charger.

 

[gnaark]

Aren't Tesla Superchargers sharing power and the more Tesla are at the charger the longer it takes? Where EA chargers are dedicated so you get 100% of the power?
