Tesla Cybertruck Owners Who Drove 10,000 Miles Say Range Is 164 To 206 Miles::Also, the charging speeds are below par, but on the flip side, the sound system is awesome and the car is “a dream to drive.”
80% is a full standard charge. You only actually full charge immediately before a road trip, because it wears the battery faster to charge to 100%, and wears even more of you hold the charge before using it.
Do for someone charging their car over night for normal operations, 80% is a functionally full charge.
So…probably the only time a consumer might actually legitimately be concerned about maximum range?
Yes and no. When you first hit the road, yes, you’ll charge to 100%. However, along the way you’ll charge up at a DC fast charge station. Those have what’s called a charge curve, where it doesn’t charge as fast as the battery charges. Think of it like filling a bike tire with a hand pump - the first few pumps are easy and the gauge jumps fast, but the last few are a lot harder and the needle barely moves. Much like air trying to resist higher pressure, more electrons repel each other as you charge the battery.
Ok, so charging. Charging from 10% to 80% takes roughly as long as charging from 80% to 100%. Rather than going to 100% at each charge, it’s often beneficial to get just enough to get to the next charger with a little buffer room. Often you’ll come out ahead if you just go to 80%ish (of course, if it’s a long stretch to the next charger or you can skip a charge with more you may have reason to go beyond 80%)
Bigger range has its obvious advantages, but a bigger battery means you can take advantage of the charge curve a little more.
I take it you don’t own an EV?
Range is always relevant. For me, my max normal range (without the very time sensitive full charge) is a day to day factor.
And I’m an outlier in the other direction: charge to 80% and usually go a week before plugging in
For what it’s worth, general consensus is that staying plugged in, even with just a normal outlet, is best practice. That has the battery conditioning run more aggressively, which is better for battery longevity. This isn’t like the NiCd batteries with a big memory effect if you recharge too early.
[citation needed]?
I have read that but wonder how much of that is so that you don’t have range anxiety. My driving is usually predictable so not a big deal
Again, it’s for battery conditioning to run more aggressively. Absolutely nothing to do with range anxiety. That’s the part that heats and cools your battery to keep it in good shape in the long run. You have nothing to gain by leaving it unplugged (of course, that’s not to say you should panic if you can’t plug in)
You take it wrong.
Then you’re an extreme outlier.
While that is true, it’s not fair to say “see they lied! In completely different circumstances you only get a fraction of the range!” Even for ICE vehicles they use ideal conditions to measure their MPG/range even though most people aren’t driving in ideal conditions.
Have you not noticed the same exact comments being made about ICE vehicles, particularly when their mileage estimates are highly advertised?
You all seem to act like this is particularly unfair to Tesla, when it’s literally the same exact discussion we’ve had for decades.
Well, no. I don’t ever recall a comparable stream of articles and discussion pointing out that, say, the new Jaguar XF has really poor fuel economy in suboptimal conditions. I agree it’s the same thing, so why is this news?
Maybe because the real world conditions is being reported by owners at roughly 50% of Teslas advertised range. When for ICE, real vs advertised is typically around 80%.
Also, there has been reasonable skepticism on the range of heavier EVs, like trucks. And Tesla being the self made premium brand, and the Tesla truck being such a weird style, is in a spotlight of its own making.
Sure if that were really the case in general it would be notable. However I’m not sure it’s true. Independent tests with data done by journalists, or various countries, do not reproduce this 50% number. At worst the range was 10-20% off which is comparable to ICEs. At least for Tesla’s previous vehicles. We’ll see if the Cybertruck is different.
Good point with your second paragraph though, yeah it does draw a lot of negative attention. It’s just the unsourced / poor methodology EV range testing which frequently shows which up annoys me…
