> The 2017 Chevy Bolt claims a 238 mile range. The Honda Fit get s 32 city mpg and has a 10.6 gallon tank, for 339 miles of range.

One charges in 5 minutes, the other in a night or so.

> So EV's are not that far behind conventional cars, so the higher energy density of gasoline makes less and less of a difference...

I've been told that filling a petrol tank means transferring energy at a rate of about 20MW. This is where it makes a huge difference.

> especially for commuters since they can refuel at home

This may be true for US suburbia. In Europe a lot more people live in flats and park somewhere in the street. Unless we install power sockets in every streetlight, charging remains an unsolved problem for considerable swaths of the population (driving to a charging station is prohibitive -- I don't want to spend an hour+ just passing time).




>One charges in 5 minutes, the other in a night or so.

EV owners often report that charging is more convenient, because you wake up with a full charge every morning. Plugging in to a charging point takes just a few seconds. A rapid charge will get you to 80% capacity in 30 minutes with most cars, but overnight charging allows you to take advantage of cheaper off-peak electricity.

Lamp posts with built-in EV charge points are commercially available. A stand-alone charging point takes up no more space than a parking meter. If there's space to park a car, there's space to fit a charge point. Charging is a solved problem, it just requires investment.

Well, this plug-in hybrid owner disagrees. I find it very tedious to have to fiddle with the cable twice on every drive.

True, which is why I mentioned lampposts. But they need to be absolutely ubiquitous. "Some" lampposts don't cut it -- charging needs to be possible literally everywhere, or there will be perpetual fights over the coveted charging parking spots. In my city the curbs are completely full of parked cars at night -- if they all are electric, there'll be a spider web of charging cables. (Also, the charging port on my car is actually on the street side of the car :'-( ).


with 200 miles of range, you don't need to find a charging space every day, many people can charge once a week. And you don't have to charge at home, you can also charge at the office, or grocery store, or any other place you regularly go.

Depending on your commute. And the weather -- cold weather essentially halves my range.

Also you need to be more careful with your charge. Because if you run out at an inconvenient time, you're stuck charging for at least 30 minutes -- if a reachable charging station is not occupied.

My BIL was recently stuck in Zürich for a few hours, waiting for a charging station to become available for his Tesla so he could drive home.

Don't get me wrong -- I'd love to have an EV. And I really enjoy my hybrid. My next car will definitely also have electric drive.

But the fact is that dinosaur juice is just far, far more convenient and practical. Certainly now, but probably even in a hypothetical future with vastly improved charging infrastructure.


Huh, Tesla and Bolt owners report a 20% reduction in range in cold weather.


Yeah, I'm sure the relation is worse for my car because of its comparatively tiny 7kWh battery.

20% is still nothing to scoff at, but probably acceptable.

That seems the likely solution. Here's a map of points in the UK, many are simply a post next to the street: https://www.zap-map.com/live/
