Not sure I understand your statement, but I think the typical EA rollout includes primarily 150kW units, with one at 350kW and one that also supports CHAdeMO. So a four stall station will have 1x 350kw CCS, 2x 150kW CCS, and 1x 150kW CCS/CHAdeMO. Sites with more stations just increase the 150kW stall quantity.
There are a few 3 stall EA sites but many are 4 stalls and certainly some with
10 or more.
EA has two types of DC charging sites.
Community or metro sites are meant for local charging (sort of like Tesla Urban Superchargers). EA metro sites in Cycle 1, ending on June 30, have from 3 to 6 charging spaces and in Cycle 2 will have up to 10 spaces. A large majority of metro sites (very roughly 70%) will be 150 kW chargers but around a third of them will be 50 kW. In Cycle 1 there will be roughly 180 metro sites.
The average metro site has around 4 spaces in Cycle 1 and 5 spaces in Cycle 2.
Highway sites are meant for inter-city or long-distance driving. Each site has between 4 and 10 charging spaces although a few may have more than 10. All highway site charging spaces are capable of 150 kW with two them capable of 350 kW. One of the 150 kW units will have a CHAdeMO cable.
An average highway site has 5 charging spaces but, in reality, they seem to be installed with even numbers of spaces. Many are 4 spaces now (like many early Supercharger sites) with 6, 8, or 10 spaces at highway sites closer to urban areas.
By the end of this year, all 484 or so Cycle 1 sites (~300 highway, ~184 metro) are supposed to be fully operational perhaps along with a few Cycle 2 sites.
Today, Tesla has about 640 Supercharger sites in the US. Maybe 700+ by the end of this year? Tesla sites average around 9 charging spaces per site. However, there are far more Tesla’s in the road and being used for long-distance driving than are CCS cars (or 150+ mile CHAdeMO).
Seattle to Chicago is going to suck based on this map.
A quick approximation check on Google maps indicates that an EA trip from Seattle to Chicago might take about 200 miles longer or about 10% longer than a trip using Tesla Superchargers due to Tesla having more northern latitude route choices.
150 kW = 2.5 kWh a minute. Math is hard
IIRC EA plans to charge tiered rates by kW. I think the second tier at 70 cents a minute starts at 150 kW
So $1 + 70 cents per 2.5 kWh
..... assuming you charge for only 1 minute and assuming you don’t join the $4 per month “Pass +” subscription plan that eliminates the $1 session fee and also lowers the tiered prices somewhat.
However, there is an expectation that Audi will cut a deal with EA on behalf of its customers. Remember that EA is VW money so EA has every incentive to promote VW brands, at least within whatever constraints allowed by the EPA consent decree.
EA has already cut a deal with Audi and Porsche.
According to my article:
Electrify America shows new mobile app, reveals new pricing plans
Each new Audi e-tron will get 1,000 kWh of charging during the first four years of use. Porsche Taycan owners will get unlimited 30-minute charging sessions for the first three years. Contracts with additional automakers are expected to be announced in coming weeks.
