Today's Supercharging Session

[JeffKeryk]

I usually charge to 95% when driving the 200 mile round trip from Los Gatos to Petaluma, but charged to 80% last night.
On the way home, we stopped to charge and get coffee in Hayward at a shopping center installation. I did not need much to get home which is why it advised me to stop after 2 minutes, but we walked across the parking lot to Starbucks. Starbucks was packed and I stopped charging while waiting for java as I had only planned on charging 5-10 minutes tops.

Metrics:
Fees: 26.21 kWh @ $0.48 per kWh = $12.57
Session time: 23 minutes.

@OVERKILL @UncleDave and others, how does this curve look? I am not sure what the Supercharger current rate was, but it ramped fast! The chargers are rated up to 250 kW max. I parked on the end, but a new Model Y Perf pulled in next to me and plugged in as we were walking away. I think that means the load is spread over the 2 cars?
Thanks in advance.

I can't imagine having to refuel for a 200 mile round trip, especially when I'd have to leave my car and occupy myself somewhere else while it recharges. I make frequent trips up your way, a 330 mile round trip, on the same day, a "flip turn" as I call it. Having to refuel for my 330 mile drive would be unacceptable for me.

Charge rate looks fine, those prices are eye-watering, but then so are your gas prices so I guess it's all relative eh? LOL !

 

[JeffKeryk]

Scott, a 330 mile round trip would require 15 minutes of Superchrging, round trip. That's a Starbucks stop. I could have made it home, as I had like 60 miles left, but wanted a coffee so I plugged in. Had I done my normal 95% charge, it would have been a breeze; I would have gotten coffee but not bothered to add fuel.

Fueling at home, especially with solar panels, beats the snot out of gas for my use case.

Also too, Hayward?!

Non-Tesla EVs pay more. Sometimes 65 cents I believe?
Had I driven the TSX or GS, I would have consumed about 8 gallons @ $6+ per gallon. Ouch!

That's still too much of an inconvenience for me. I get annoyed with myself when I have to stop for a quick pee!

I usually take 280 through The City, but they are repaving 19th Ave.

Yeah, I read about that. I cannot imagine the traffic issues associated with that, but it needed to be done. Being a South Bay guy, the East Bay always felt like a foreign land to me. I have a strong dislike of Hwy 880 through that area.

Charge rate depends upon many things. I don’t know what you started at, but the full rate of charge is dependent upon state of charge, impedance (related to temperature amongst other things which is why they condition the battery when preparing to charge), etc.

I’d say 210 at a 250kW charger is pretty decent. Your pack health may also not be good enough to accept a full 250….

Im not familiar enough with the car to know if that display is peak or average but 210KW is humming along pretty well.

On whether the load was shared when the other guy hosed up - that depends on the architecture of a given site and how the cabinets were arranged.

Its almost time for me to jump into something...

Almost no mainstream EV needs to charge on a 200 mile trip.

You are forgetting about the two fill up trips you need to make for the 330 mile trip in the ice car and focusing on the one the EV needs to make.

Are they eye-watering? Sure, compared with 0.14 kWh locally, but $14 to go 200 miles seems really cheap.

Cost/mile is reasonable even if cost/kWh is high.

 

[alarmguy]

Since speed determines distance, what speed were you driving that 200 mile trip?
My understanding is EVs burn up useable mileage at 80 MPH

 

[slo town]

You are forgetting about the two fill ups you need to make for the 330 mile trip in the ice car and focusing on the one the EV needs to make.

How do you figure? Both have to be fueled/charged prior to the trip. Then I have to refuel when I get home (although I still have about 75 miles of range left). Even if the EV has the range to make the 330 mile trip, it has to be recharged when it gets home.

The Ice car doesn't fill itself at your house prior to the trip - you have to fill it somewhere before the outbound trip, and that somewhere isnt your driveway it's a gas station.

Nor does it fill itself back up at you house after the trip.

Perhaps " trips" or "stops" vs the term fill up would have been more accurate.
Either way on a 330 mile trip it's 2 vs one as long as you can charge at home.

I had just plugged in; it was ramping. I had I probably had 50-60 miles out of 300; perhaps 15-20% remaining? Of course the car preheated the battery for charging. I had only planned on charging for 5 minutes, 10 max.

Let's just say there was no Regen on this trip. 80 MPH on 280 above Page Mill Road on an early weekend morning is average.

Fair enough, but I don't have the electrical service at our house to charge an EV, at least not quickly.

Sue and I like taking road trips. Often times long ones. The convenience and speed of a gasoline fill up is paramount to us.

Our oldest son got promoted to a position where he was provided a vehicle to do his work, a Ford Lightning of all things. But, given the distances he has to travel, usually urgently and never to the same places, he exchanged it for a gasoline powered Camry. He told me range anxiety was a real thing in his situation.

48¢/kWh is about as average as you get for DCFC right now. Maybe slightly above average, as DCFC prices have dropped a bit recently as competition has increased.
