Seems too high. If getting a 50% charge, say 12kwh at 0.15/kwh thats $1.80 for the cost of electricity. (Our rates are 0.09/kwh). Yet charging $8. That will choke the EV market before it gets going.
...
It should also be time based, ie a per minute charge. You want to encourage people to get off quickly. With this pricing, whats to stop someone from plugging in and leaving it there for hours. Same price as someone who wants a quick 5 minute boost.
LOL! $0.09/kwh??? Even on a non-TOU plan in PG&E land, there's no way to even get electricity that cheap. On E-1 (non-TOU based), even if you stay within the 1st tier, it's a bit over $0.13/kwh.
Try putting in the 95136 zip code into http://www.pge.com/myhome/myaccount/charges/" onclick="window.open(this.href);return false; and select no for CARE (for low income people) along w/your monthly electricity use. Compare your bill to the calculator (which is a bit too low, since it doesn't include tax and fees). I'd be curious to hear some numbers.
I can't speak to commercial rates vs. residential, as there are many of the former, in addition to possible demand changes on the former. Per http://www.pge.com/myhome/customerservice/financialassistance/medicalbaseline/understand/" onclick="window.open(this.href);return false;, I'm in area X, so I get allocated 11.0/kwh day in "summer" and 11.7 in "winter".
I recently switched to E-6 that's TOU based. You can look at the rates at http://www.pge.com/tariffs/ERS.SHTML" onclick="window.open(this.href);return false;. E-1 is the default non-TOU plan for residential.
There's got to be some charging losses when doing DCFC so if you only put in 12 kwh, more was consumed.
I agree that it should be per minute or per kwh.

the Prius has other downsides (noisy, jerky power delivery, pollutes like crazy).
Noisy, yes. Jerky power delivery... not really. Pollutes like crazy? No. CA and CARB-spec 04+ Priuses are AT-PZEV (http://www.driveclean.ca.gov/Know_the_Score/Understand_the_Smog_Score.php" onclick="window.open(this.href);return false
. Since they get about the best FE of any ICEV, they have very low GHG emissions compared to all other ICEVs (http://www.fueleconomy.gov/feg/Find.do?action=sbs&id=33324&id=22016&id=33558&id=32154&#tab2" onclick="window.open(this.href);return false
. In order to get for an ICEV to get lower GHGs, it has to get better FE than the Prius. I know of 0 mass-market ICE cars currently sold as new in the US that do.
