R1S Actual Range at 80%?

[Jared2]

Got the text this morning that my R1S is finally ready for delivery!!

I have some 200+ mile trips coming up and I wanted to know what people’s experiences have been.

I always hear that you should only charge to 80%, but if I have to go 292 miles with my family, would I make it if I charge to 100%?

I was looking for a range calculator for the R1S, but didn’t find anything good.

If you need the extra, just top it off to 100 the night before you leave. You're likely going to need to top off along the way anyway just to be safe. Even if it's only a 15 min charge. It's generally going to be more comfortable topping up briefly so you don't start getting worried about the range the whole time. Just watch the distance remaining and range remaining numbers and if they diverge wildly then you need to slow down or find a charger. Even 5 mph can make a big difference if you need a bit extra.

At 80% you will get ~250 miles of range, higher in comfort mode. If you don’t plan on stopping before driving ~200 miles, then definitely charge to 100% the night before. Then, you’ll have over 300 miles of range, just to be safe.

I would think conserve mode would be better for what he is doing, with a top off to 100% the night before?

I made this trip regularly. Top off 100% and got plenty to spare even in all purpose mode

There are a lot of variables for a trip. I drove cross country and typically was charging to 75% and going between 160 and 200 with no issues. You want to know where the available chargers are and pull in and juice up if the numbers are lower than you are expecting. Hills, wind, rain, cold, speed all impact the expected range. I find the time it takes to go from 95% to 100% is not worth the time it takes and only adds about 10 or so miles.

I have the R1S on 22s, my longest stretch I had everything favorable, driving around 70mph on a day in the upper 60s charged to 95%, drove 260 miles and had an estimated range of 68 miles left.

My worst stretch, charged to 75%, drove 75 mph in unfavorable terrain and a 20-30 mph headwind. Initial estimate was around 220 miles, drove 140 and only had about 20 miles left. if running low slowing to 60-65 mph makes a big difference.

I do find the range estimater on the navigation does a very good job and it does adjust as you progress, usually very close when I reached the destination so I almost always set it if going on a trip to help gauge if I should stop early or not.

If you are down under 50%, you can get a decent amount of miles in 10 or 15 minutes so if you take a bathroom stop where the chargers are you would not even really be waiting on the charge.

Don't hesitate to charge to 100% when you need it but it is just the one charge the night before that you will charge to 100%. The top of the battery takes forever to charge, so you are not going to charge to 100% when you are sitting around waiting. Unless you really need a bit more range, I would stop when the charge starts ramping down, perhaps at 70%.

Also keep in mind, you should not actually plan to drain it down to 0%. You need to keep enough in reserve so you don't end up stuck if you come across bad traffic, or a detour, or bad weather, or a charging station that is full or non-functional. You should plan to stop for recharging by 20% (sooner if you would need more than that to find another charger if this one doesn't work).

So on your first leg you will have about 100%-20% = 80% to work with, and after that you will have 70%-20%=50% to work with.

That is 240 miles for your first leg, and then 150 miles after each recharge.

Definitely agree to keep the car above 15% or so when possilble.
I'm a little confused about the reluctance of so many to charge to 100%. One should avoid charging to 100% with regularity but I can't see how going to 100% a handful of times each year would make any difference to battery life/efficiency. On the Model S I occasionally charged to 100%(probably about 15x per year) with no negative impact over 8 years.
On trips with the R1S thus far, I've utilized the destination chargers to get to 100% overnight before long drives and it's been a big help. If you get to a hotel at 50% and have a decent charger there, it's very easy and convenient to get to 100%. Furthermore a lot of destination chargers are free which is a plus.

You should be fine to charge to 100% as needed before a road trip. The key is to not let these batteries sit at 100% for an extended time.

ill be using my truck for 230 mile trips on a regular basis (1-2 x/month) from the Bay Area to Lake Tahoe and will charge to 100% before departing on the way up, and likely 85% on the way back.

that’s a 4ish hour trip, and usually there’s a pee break along the way. I figure that pee break will be time to stop and charge a little bit as well

Depends on the wheels you have on the vehicle. The 20" AT Wheel/Tire is the most inefficient. At best about 290 miles of EPA range on that. Around 310 ish EPA with the 22s and the 21" is the most efficient at 328 EPA. Now that is at 100% but remember you don't want to run it down to zero. Plan on using about 90% of the battery that way you have a 10% buffer when you get to the charger.

I charge to 80% daily. At 80% worst case you will have about 230 EPA miles of range (with the 20" AT) and at best 260 EPA. Charging to 100% for road trips is not a problem...you just don't want to charge to 100% every day...only when necessary.

Your actual range will depend on many different factors such as wind, ambient temp, load, rain will reduce range, and speed is big as well. The faster you drive the lower your range.

Use ABRP to plan out your trip. The NAV will also tell you when and where to stop.

Speed is your #1 variable (assuming your tires are properly inflated). Aero is the limiting factor on range.

I’ve gotten nearly 400 miles on a charge before because I was in conserve, with a tailwind, at 65mph. I’ve also seen the other end of that - headwind, all-purpose, driving 75mph+, seeing around 300 of range. This is with 21s btw. It will be lower with the stock 20” pirelli ATs.

Interesting to check the forum today and come up on this thread.
I drove our kid to a camp yesterday, ~220/232 miles in conserve, few hills, mostly rain, ambient temp 65-68, cabin temp 72. driving moslty 65 -75mph over 80% of the time and consistently under 80mph the remainder of the time. We covered 232miles and returned to 31 miles of range on parking. that comes up to under 265. I was wondering of these in my opinion "mild" deviations from Ideal would account for such a drop in range, especially as the car actually gave me a read out of 312 miles about 10 miles from home with 6-7 of those miles on the highway at about 75 mph, when I switched from all purpose to conserve. That was my first over 200 mile drive with any electric car, so I am a newbie in long range efficiency management. I have had the R1S on 22's for just 2 weeks. For what it's worth, no chargers to and fro....the camp was in the Boondocks. I'm fairly surprised one can in practice get over 300 miles from this truck if noy downhill mostly with tailwinds.... Any pro tips appreciated and apologies for jacking the thread!

Let's be honest here: charging to 100% pretty much disables regen. If you are a few stop and go's from the interstate or there's traffic, 95% probably makes more sense. Literally 5 miles difference max b/c of the regen hit

If you have to use the heater at all, or the weather outside isn’t in above 50°, you will absolutely not make 292 miles on a highway even if you charge to 100% and run in conserve mode. The car needs a heat pump
pretty badly. Fortunately it’s summer! so you have six months to prepare

 

[Jared2]

Wow, this is immensely helpful and exactly what I was looking for. Also, the boost to my “range anxiety” my wife is having at the prospect of going full EV (We have a Wrangler 4xe).

BTW, I ordered with 21” wheels because I was concerned about range reduction, but I hear the 22s are just as good (and much better looking)

The only other thing I’m a bit worried about is ”vampire battery drain” which I hear is pretty bad on these right now.

We live in NYC and regularly drive to the Mass boarder or to the Adirondacks. I like what someone said about stopping even for 15 minutes to add some miles on a high speed charge.

Thank you all very much!! Very excited.
Wishing I hadn’t driven the wrong vehicle down here this week… supposed to trade in the other… they just told me this morning. I may change my plans for tomorrow and round trip it to get my older one to trade.

All the best!
