Drive for two hours - Charge for an hour road trip.

1c in a SR should be 65kw. Just saying. That was 1 of the main factors that drove me to an ER battery. Per minute I can cram more in if possible.

Side note, the OP's got to be:

The 2021 SR has a 75kwh battery with 68kwh usable. The 1C rate would be 75kw.

Did you know it’s actually not recommended to let young kids wear jackets in car seats? I have to take my kids winter coats off of them when I buckle them in. Kids seats also do not have heaters like the front seats. So no, I’m not freezing my toddler to death while we we drive to grandmas by turning off the heat. That’s not a reasonable solution.

I'll admit I never remember about those pesky things so I'll concede there. But there's a difference between no heat and less heat.

I saw a story today about a 103 year old vet who got charged $600 to heat his home. You should have just told him he should have sucked it up and turned his heat off if he didnt wanna pay that.

Non sequitur.

I'd rather the manufacturers list the C rate then use kW. C rates are used to normalize against the capacity.

That doesn't reduce the cost for providing such high surge power being on-demand at any moment though. That's why demand charges exist - to cover the high cost of providing it.

Understood, but some energy providers are already doing this such as Nevada Power.

There needs to be a way to operate DCFC at low usage until demand picks up. There are other ways to do it, I just pointed out one example.

There are certainly different ways the cost can be divvied up. I really don't know whether the current way demand charges are typically applied is most fair or not. If it is pretty representative of the extra cost, then reducing that probably means spreading it out to other users (in effect, other ratepayers subsidizing part of the extra cost for making such high surge power available at that station). I generally wouldn't be in favor of that. But I really don't know if that's the case.

Our road trip charges are usually 25-30 minutes. That's because we're usually adding about 50% each time, not 70% or 80%. We like keeping enough "in the tank" to reach a backup charger just in case. We're commonly living in the 30-80% area of the battery.

How long do you drive between those 50% charge stops? Like an hour?

How long do you drive between those 50% charge stops? Like an hour?

91x 0.5 = 45.6kWh

45.5 x 3 = 136.5 miles

Answer - ~2 hours

How long do you drive between those 50% charge stops? Like an hour?

A typical day for us is around 500 miles, 3 DCFC stops. First leg starts at 100% (home or hotel) and is longer, maybe 150 miles. The remaining 3 charge to 80% and average around 120 miles each. Varies based on where the chargers are located, of course, but that's the ballpark.

Sorry, but if people want to post that 2 hours of driving takes 1 hour of charging, I'm sorry but that's just ridiculous and gets the responses it deserves.

I don’t know what to tell you, bub. I guess some of must have gotten defective battery packs. Sounds like a class action suit to me. I sure wish I’d gotten one of those packs that lets me drive 3+ hours at highway speeds in the winter and then only takes 30mins to charge back up. Man that sounds amazing.

 

[Mirak]

Nah, nothing defective about your battery pack. They just gave you the wrong one. You should probably start another thread on that as we haven't had an "I got the wrong Battery" thread in what, 13 hours?

@Ford Motor Company Can you help me out? Why can’t I drive 3+ hours at 75mph in the winter?! I bought an extended range!

Charging for an hour at a functioning 150kW+ DCFC means you're doing it wrong, unless there's either very poor DCFC coverage, or it's very cold (and I mean actually mean cold, not balmy temps in the 30s). Add route preconditioning available with 3.6.2 and I don't see the need to always charge for an hour on a cold day. Also, don't skip any 150kW stations en-route unless it's very close to a previous charging stop; it's way more efficient with time to stop more frequently for shorter charge sessions: 1) The battery stays warmer between sessions; 2) You want to be at an optimal part of the charging curve when you plug in.

If you read the original post you would see that the one hour charge time includes the time to divert to and from the charging location, try several different chargers before you one that actually works etc.

 

[Mandretti]

So learning, and expanding one's knowledge, is unacceptable. Got it.

On the other hand if a person, male or female, has difficulty operating a remote, or charging their phone, even with a PhD in Nuclear Physics, they may not be good candidates for “expanding one’s knowledge “ in the arena of planning and executing an EV trip.

 

[Mandretti]

OP here. The one hour of charging includes the overhead of diverting to a charging location, finding a charger that works through trial and error, connect time, actual charge time (25-40 min) and then getting back to the Highway you were driving on. The more times you stop, the more of that overhead you have.
