EV Charging Doesn't Need to Be as Fast as Gas, Ionna CEO Says

Lets say you have a 300mi range EV. that sounds great, until you realize you can’t actually use it all.

We like to save the bottom 20% for emergencies and battery longevity, and fast charging is too slow above 80% to be worth it, so effectively, on a road trip. only the 20%-80% range is usable. Your 300mi+ range just turned into 180mi of usable range. And then factor in ~10% battery degradation over time, or range reduction in winter conditions, and you could easily have as little as 150mi of actual usable range between charging stops. And that’s assuming the charging stations are perfectly spaced apart.

That’s only a little more than 2 hours at highway speeds. And that’s not along time to be driving, even for a single person. In gas cars, we will regularly do 3-4 hours without stopping at all. And if we do stop for a break, it’s rarely at gas stations or places with charging stations. Those are typically awful places to spend the limited amount of time you have on a trip.

In practice, the charging interval is far, far less than the ideal 300mi and far more frequent.

Umm, there are no EVs you should be going 75mph for hours at a time in unless you want to trash your range.

Not sure if you have ever actually driven an EV, but typically in my 300mi range vehicle, I usually stop every 200 miles, roughly every 3 hours for charging, stop for 20 minutes and am back on my way. Sure, am I often a little slow than if I had gas? Yes, but that’s ok, I also always arrive in my EV refreshed, have eaten, and not wore out.

All the arguments are like this. You shouldn’t do this, you shouldn’t do that. Well of course if you can avoid all the downsides EVs would be perfect, but we don’t live in that perfect world in your imagination where everything works and we always do what you think we should be doing. If EVs were as good as everybody says, you wouldn’t have any trouble convincing people to use them. Why can’t anybody just admit that there are real downsides which in some situations become a deal breaker?

I think the downsides are going to be mitigated soon. There are cars that get 400-600 miles of range. There are also new battery materials that can be charged in 5-10 minutes. Once one of those solutions become widely available, adoption will pick up. Also, gas hitting European prices in the US of $10-$12/gallon would also make people switch damn quick.
