Charging rate appears to be below 1C

[Outdoors]

CT is the best electric truck out there in my opinion. But it is a Tesla so of course it is, does not change the fact that the charging curve is pretty sad and when towing folks are going to have to sometimes sit at a supercharger for 60+mins to make it to the next one.

For some large areas with super high speed limits, and then keeping up with traffic makes it hard. Here in Montana. There are stretches in the winter if one has the courage to go 80 with the heat on, one has to sit a supercharger an hour plus to go through a couple eastern MT supercharger sections pulling nothing. I can't see how it is possible trailering in one.

Is there an official list of states Cybertruck owners aren't expected to be convenient in ?

Just a personal observation. Not that it matters. I often chat with the truckers. Sometimes I wonder why I chat with them.

^official list of states. I don't know. It was designed where it was warm. I don't think anyone with a octovalve or anything has figured out the real cold when it comes to EV travel.

I was being sarcastic. It's silly to suggest a whole state of Montana has charging inconveniences because it's "rural living." Most US states have vast rural areas, some of which are also very cold in the Winter. So if one is going ANYWHERE else in the US, they're likely to pass through those areas and experience those issues regardless of where they actually live.

These posts are always funny.

"The CT sucks in [insert category]"

Yeah man, its a product made by flawed humans and there are compromises. German cars are luxurious but require lots of maintenance, Japanese cars run long but rust, some American cars have glorious V8s but have PlaySkool plastic interiors, Hyundai has some cool EVs but their dealerships will always cripple the ownership experience...pick your poison.

If it's really a deal breaker, at least the values are holding up pretty good as long as you're not on Cars n Bids 🫣.

No idea who's right, maybe the charge rate is bad? I haven't had issues I guess, most of the time I have to rush back to the truck to move it before we're even done with our highway stops. Not defending it one way or another, just saying it's simply not a problem for some.

This pretty much lines up... note how it goes below 1C just at about 50% SoC... and yes, that initial pump will be a bit higher on 350kW stations, but it drops off just as quickly as the 250kW one...

Are you implying that the charger should be at 1C for the duration of the charge? Honestly just trying to understand what you're getting at. Also, just because you're at a V4 station doesn't mean you charge with a different curve. I live DC charging design every single day for a living.

My DC charge curve over the life of my vehicle, ~ 2 years and just over 2MWh of DC charging.

No v4s in my area and some older SCs that I frequent that don't exceed ~155kW. Looks like there's at least 1 urban SC in there too. 2.08 MWh over 17h 22m of DC charging. That's an average charge rate of 119.77kW, including all charges where I either didn't precondition sufficiently or was limited by SC output. I don't usually let the battery drop below 10% or charge above 90%, so data points are extremely limited at those extremes.

It's pretty obvious from that data that if I always had 255kW or better chargers available and always preconditioned, that I would easily surpass 1C average charge rate.

I will take a guess. Basically Tesla hasn't produced with its own batteries or others very meaningful improvement in charging times over the years. Sure cell density has gone up. So less cells etc.... Yet charging has yet to see any leap in speed. Maybe like tiny footsteps in progress. Just a guess.

I am implying that the charging curve needs to average out to something above 1C.

Just in your opinion or?

How is that obvious given you have few datapoints going above 80% ?

I welcome you to try selling a "breakthrough" EV with a marketing statement "our vehicle fully charges in just over an hour" and see how that is taken by the customers. Obviously that wouldn't go well, which is why in this case they're bending into a pretzel with the statements like "it's only 5 minutes to charge for additional 2 hours of driving." But hey, just my opinion

All I know is my battery has always outlasted my bladder, and I've never charged for an hour.
