EA Megathread

[Pragmatic]

EA only limits the charging on non-interstate urban chargers. That said I would never charge above 80% its too painful.

The charger I posted about is literally the exact opposite of this. Interstate in a rural area.

A possible solution is additional fees for beyond 85%. Like idle fees. Call them what you want. Road trip fees, congestion fees, inconsiderate of others fee.

EA could also utilize a location based virtual queue. If there are say 5 cars in the virtual queue and you are reading your book oblivious to the world at 85%, make the rate absurd like $5 per kW. $10 per if there are 10 cars waiting…

Come to think of it, they can barely get PnC to work well so that might be like year 2035 tech for them….

EA can’t even keep the chargers operational let alone be able to provide a reservation system through the app. The fact they still only deploy sites of 4 to 6 chargers only is ridiculous and helps contribute to the backlog of cars waiting.

People can shit on Tesla all they like but at least they’ve got multiple sites of 20,40,60,100 chargers. Show me an EA or EVGo site with 20+ chargers. They’re almost non-existent

 

[Pragmatic]

Most of the areas people need to charge to a high SOC are remote. I'd rather have 10 6-stall stations than 1 60-stall station.

So you haven’t done a road trip on a holiday period then? All those 6 station locations on the interstates are full with lines of 10+ cars most of the time. Larger sites are definitely needed.

 

[Buffalo Bob]

I think this 85% limit will be more effective if it is paired with a painfully expensive idle fee. Many people at urban chargers do not seem to care a hoot about tying up chargers for well after their charging has completed. For that matter, I think the idle fees, after a few minute grace period, should always be painfully expensive.

 

[Pragmatic]

I did not say there were enough chargers. I was trying to say more small stations would be better at solving charging deserts than one large single station.

I’m sitting at one now. But your point is valid.

From the FAQ:

How were stations selected to be included in the Congestion Reduction Pilot?​

The stations selected for this pilot are highly-utilized locations that were carefully selected in urban areas where DC fast charging is more accessible with other stations nearby. Locations along highway corridors are not part of our Congestion Reduction Pilot to ensure EV drivers can get enough charge to make it to their destination. You can also visit the Locate a Charger page to find another charging station near you if you’d like to explore other locations not involved in the Congestion Reduction Pilot.

Are you going to do this at charging stations where you must go long distances between chargers, and you may need that 100% charge?​

We are currently only piloting at the locations listed above. We considered station utilization and the distance between stations when selecting locations for pilot programs.

How are you choosing the charging stations that have this limitation?​

The charging stations in the Congestion Reduction Pilot were chosen due to high utilization and queuing concerns.

Will idle fees apply since I am not able to charge to 100%?​

Yes. Once your EV has reached 85% State of Charge, the charger will stop charging your vehicle, and the 10-minute grace period will begin before idle fees are incurred.

Yeah they all look like they fall into that example of “metro” areas. With the exception of the one in Pennsylvania that I pictured and is listed. The Sheetz (gas station/connivence store/made to order food) only exists because of the interchange between two major highways. And is far from urban.

 

[Pragmatic]

It's also located in an area with numerous DCFC near enough that there is little need to charge past 70% never mind 85%.

 

[EVCar]

Hypothetically, if it takes 80 minutes for a level 2 charger at 11 kW to add x amount of charge to a battery, would a DCFC at 44 kW add the same amount of charge in 80/4= 20 minutes?
Probably a lot more complicated, but I just want to have a rough estimate.

The DCFC will likely be slightly faster. For level 2 charging, there is a voltage boost and AC to DC conversion. The losses are between 10% and 15% for energy into the battery. There are no conversion losses for DCFC but still some resistive losses for current into the battery. 44kW is slow enough that it may not require battery cooling depending on the ambient air temperature and how the battery was preconditioned. Hence, my conclusion of slightly faster for DCFC.

Thanks, Neil.
Trying to figure the worst-case scenario where I have to do 50 kW at Blythe, bypassing the Quartzsite problem child.

Had a repeat "wrong charging station" in the app on the way home. The station I'm Gallup, NM somehow doesn't handshake to Lucid so when you try to authenticate it shows the station you previously charged at instead of this station. Last time it showed up as Flagstaff and this time it shows up as Santa Rosa. Had to load the app and add a card to get it to charge via direct payment
