Title: Range anxiety from battery icon
Post by: Laconian on February 01, 2022, 12:37:31 PM
I wonder if EV perception suffers because the state of the battery is featured so prominently in the UI. The specter of limited range looms large, with lots of reminders about instantaneous consumption, estimated miles to empty, percentages, and whatnot. Of course it makes people anxious. I imagine people would feel the same way about ICEs if gasoline consumption stats were presented so pathologically. Perhaps the higher end EVs with battery packs larger than 70+ kWh should just throw up a "good enough" approximation of an E->F fuel gauge?

If you go on a road trip, you can summon the "stats for nerds", but otherwise - just go about your daily routine, plug in your car every so often, and don't bother worrying about the gauge.

Maybe plugging in a longer road trip into the GPS would indicate to the UI that more attention should be provided to the battery state.

There's probably some truth to this; but "range anxiety" keeps a lot of people from buying electric, even ones that have never seen the displays.

Part of it is fear of what would happen if the car died; or of having to take a lot of time to recharge. I think the answer to both of these problems is more familiarity with EVs.

I don't think just plugging in the car every so often and forget about it is viable.  The penalty for running out of juice is way worse than running out of gas.  And you can resolve running low on gas immediately, almost anywhere.  IMO, EVs only work if you have a regular commute, can charge nightly from home, and have an ICE for road trips.

I think range anxiety is an issue when your range is less than 200 miles.  Once the range goes above 300, it goes away because it's the same as any normal car.  You may be limited to the amount of places you can charge but that's really not that much different than driving on a long trip in the middle of the desert and the next closest gas station is 30 miles.  With the Tesla and the built in supercharger network, it makes this calculation a lot easier since it can help you plan out your supercharger stops allowing you to stop for as short of a time as possible with pee breaks in between.  I did a round trip to SF when the car was less than a 1000 miles and it was pretty painless.  My random trip to the Salton Sea was a bit more daunting since I finished as a charging station with 1% left, but then again, there was no gas stations that I drove by during the whole time either so the result would've been the same.

The anxiety scenario that gives me the most pause is long-term airport parking. You park in a deck. Go away for a couple of weeks. Return after an 11-hour flight: sleep-deprived, disoriented, grumpy, & needing a shower. The car's charge has ebbed too low to get you home.

Self-discharge is something that rooftop solar would be an answer to.

Long-term parking lots & decks are going to need 120V trickle charge outlets at every bay. I would not want to arrive before a flight & find just a dozen or so EV spots. All taken.

SLC airport has a lot of chargers. 20-30 at least. And then the covered 3rd party parking lot down the street has some L2 chargers + 120v outlets if you want to just bring your portable L1 charger. I've parked our Bolt at both lots with no issues.

oh, I meant on the roof of the vehicle. A 120-150 watt array should be enough to provide enough power to keep the batteries from going flat while being parked.

Henrik Fisker seems to agree with you on since he added solar roofs to his previous and current cars.

Speaking to range anxiety, I have less than 1/4 tank of heating oil.

I'm sorry, but "Range anxiety" brings to mind trying to actually fire some of the ancient rifles I've purchased over the years. I was asked by an RO why I was firing the Arisaka upside down. Well, sir, that's because if the spacing is wrong and the damn thing explodes, it will be into the table, and not me.
Turns out the the old Jap rifle shot just fine. Accurate as hell, as a matter of fact.  :ohyeah:

Arisakas are strong as hell; you'd have to do some serious fuckery to blow one up- Now my Martini-Henry, which was sold as a "wall hanger only," I shot that the first two times from a lead sled with a string. And the 7.62 Indian Lee-Enfield? Well those are known as being marginal- you can't load full power .308 rounds into them despite most people thinking 7.62x51 is the same round as .308 Winchester- they're the same size within a few thousandths, and they'll all fit; but the pressure standard for .308 is a little higher.
