Dear CometGuy and other Interested Taycan Owners:Interesting report. But how do you get 4.5 hours of fueling time spent per month for people who mostly charge at home (page 13)? I'm thinking it would be more like 3-5 minutes per month (to plug in and unplug once a day, each) if plugging in every night in your garage. Here in Mass., there is no government charge to own an EV (to offset the gas tax), and our current electricity rates are such that we see nearly a 50% drop in "fuel" costs in going from ICEV (gasoline only) to BEV (electricity only). You also don't seem to acknowledge that relatively few BEV owners go on long cross-country trips in their BEVs (because of all the problems/reasons that you cite regarding public-charging infrastructure and associated technology), meaning that the vast amount of BEV usage is within a full charge of home (roundtrip). I'd say it's fair to say that 99% or more of BEV charging by owners is at home or at work (or possibly at EA chargers by owners of car brands paying for the first few years of charging, like Porsche; one Model S owner that I know who bought while Tesla was still offering lifetime unlimited charging goes to a nearby Supercharger station once a week or so and never pays for any charging). So this rather skews your report, which seems to assume that BEV owners do long-distance road trips at a similar level to ICEV owners, which is clearly not ture.
Here is the rationale for the method we use in our EV vs ICE fueling cost study, which I am summarizing (bluntly) here, and which is stated (extensively) in the actual report on the https://www.andersoneconomicgroup.com web site:
1. We standardize on the same mileage for EVs and ICE vehicles, because the purpose of the report is to compare real-world fueling cots for typical drivers.
Thus, we don't allow for EV drivers to "baby" their cars, while socking the ICE drivers with full costs. The assumption for mileage is the same for both vehicles.
2. We include 3 charging modalities for EV drivers, varying residential and commercial charging. This recognizes the reality that nearly all drivers must rely upon commercial chargers some times, and many drivers use them regularly.
3. I fully acknowledge, and have spoken of publicly, of the difference between the typical cost and usage of EVs among US drivers, circa 2019-2021. However, the report and our analysis presume that typical buyers in the near future will (and are) considering EVs, and therefore we should consider costs for the majority of households. These households do not have extra cars, often do not have single family residences with attached garages, and must do "daily driver" tasks with their vehicle.
Look for a second edition soon (I am writing this in January 2022)!
