Assuming you get a typical 20 minute charge starting at LBW, you'll pick up about 10-12 kWh on a 50 kW CHAdeMO.
That would be typical if QC stations were as ubiquitous as gas stations so you could fill up when you were near empty. But since they're few and far between, either you can do without QC or you may need to fill up when you're close to half full when you just happen to be near one of those rare QC stations. A $10 charge from 50% to 80% of 21 kWh usable capacity is $1.59/kWh, $0.40/mile - the same
incremental cost as a 10 MPG SUV with $4/gallon gas.
Yeah, the incremental cost of quick charging is 10-25c/mile at the above rates. But as I've always said, looking at the incremental cost is the wrong way to do it, you should be looking at the average cost since you are also picking up 50-70 miles of electricity at ~4c/mile
I agree that total trip cost is more meaningful than incremental cost, and all my trips enabled by QC have been much cheaper than driving the ICE all the way.
Anyway, I will pay $10/session if I need it. I just wish there was a lower cost option for those times when I don't need a full QC...
I don't want evGo to rethink their total revenue that makes the business profitable, makes them want to expand, and makes other companies want to come compete with them. What I
hope they rethink is having the same horrible flat session pricing as Blink, and the even worse flat monthly subscription.
A $10 session price, even more so than Blink, will cause people to stay longer than they need to get their full value. Since QC charge rate decreases as SOC increases the last few percent of charge will take much longer than the first few percent of charge, and we'll have longer waits in line to begin our charges. The monthly subscription is even worse since to get your best value for your money you might charge at evGo in preference to charging at home. The only mitigation there is that they do also have a per minute charge, but still the price structure encourages waste and long lines.
If instead they had a lower monthly fee for access to the network and a higher per minute fee for use, they'd get many more subscribers, shorter queues as people took only what they need, and they'd probably make more money.
