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.

The usable range is 10%-100%. Nobody starts an EV road trip with much less than 100%. Though you may consider cutting a mid trip fast charge somewhere around 90%. Usually for me that’s because I see that I can get to my destination without going up to 100%

Charging stations will eventually be spaced at close enough distances that you don’t have to think about where to stop. In a mature EV market there’s generally many more EV chargers than gas stations along a given route.

And if we do stop for a break, it’s rarely at gas stations

I’m not sure I’ve ever stopped at a gas station to fast charge. I stop at roadside McDonalds (we have kids), cafes, supermarkets (last stop before a trip to a cabin), etc.

How, in this day and age, could you not be aware that fast chargers are put up in more diverse places than gas stations? They’re not stinky. They don’t need to be separate from the businesses where car drivers want to spend their time.

I’ve stopped at a fast charger at a small cafe in the middle of nowhere on the top of a mountain, you could take a wonderful hike there while your car charges. You do know you can walk away from the car while it’s charging… right?

My trip to my family cabin is around 3 hours. And the last 30min is through an actually snowy dirt road up a steep climb. And I still have 40% or so left. With skis in the roof. So get outta here with your arm chair expertise.

Incidentally I don’t have to fast charge on this trip at all since we have electricity at the cabin. Super slow but I can get at least 80% which is plenty to get back.

Anyone still bringing up winter in an EV conversation should be laughed out of the room now that Norway is at near 100% market share. And no, you can’t use “Norway is small” as an argument. Road trips are common here to start with, every other family has a cabin in the mountains. But Norway is also part of Schengen. The borders in EU/Schengen are open just like the US. The first post I saw on my EV car models Facebook group was a person planning a trip to Croatia.

Nobody starts an EV road trip with much less than 100%.

That’s exactly the problem. Yes you start a trip with 100%, but that only happens at most once per day. What about in the middle? You willing to sit a fucking Walmart for 1hr to get to 100%? We’re not talking about a trip where you drive 3hr from home to the destination. I’m talking about road trips where you go half way across the country and do 5+hr of driving in a day, across multiple days.
