The 7mph claim is inflated. The rare EV gets more than 5 mi/kWh in any situation, especially highway driving, and your L1 charging is getting you roughly 1 kWh

> The average car is driving 60 minutes per day
This is a sleight of hand. Non-average situations arise all the time.
Your proposal is ridiculously burdensome and not especially helpful.
- stavros 2y agoOwning an EV, I can confirm your numbers. I'm in a 240V country, but level 1 is still pretty slow. It's great for the home, but I'd want at least 3-phase AC charging when I'm out.
- loeg 2y agoYeah, FWIW I also have an EV, get ~2.2 mi/kWh highway and ~3 around town, and L1 charging on 120V gets me, you know, 1.0-1.1 kW.
- ac29 2y ago>your L1 charging is getting you roughly 1 kWh/hr 12 and 16A L1 chargers are common which is 1.44 and 1.92kW respectively at 120V. Its not 100% efficient but they definitely deliver more than 1kW to the battery.
- loeg 2y ago12A L1 doesn't actually deliver much more than 1 kW in practice. Closer to 1.0 than 1.4.
- coryrc 2y ago> Non-average situations arise all the time. Of course. We already have blanketed the country with level 3 charging. You can reach 99% of the country solely using Tesla Superchargers. The non-average problem is solved. What we need to solve is the "can renters buy EVs knowing they will always have reasonably-priced place to charge" problem.
- loeg 2y agoI think the authors of the article would opine that we don't have nearly enough DC fast-charging, actually (and I would agree).
