Standard Range Plus Supercharging Speed

[momo3605]

2019.20.2.1 here. Charged from 14% today, and it was capped at 100kw/464 miles per hour

I used ORBW, drove for about 30 mins, and it was about 80 degrees F so definitely not cold soaked

They have limited it to provide an incentive to upgrade to more profitable models. It's a marketing issue, not a technical one.

so your car have extreme marketing issues then?

I will be hitting a supercharger in Wythville, VA this coming Saturday (6/28). I have the SR+ build date 06/19 and just received the latest software update (2019.20.4.2) last night. I will report back my findings as well.

If possible make a video using "time lapse" of a full charge and share. It is important to capture the time in the video as well as the charging rate and battery level. If not, I'll do mine when I get the upgrade.

If they let the Sr able Sr+ charge as fast as possible they'll still charge slower than the lr. The cars will sit at the superchargers less which leads to a faster turn around which leads to Tesla having to install less superchargers. Even if it's 10-20% it makes a difference. Another point is they don't advertise that the LR charges faster. I had no idea my Sr charges slower when I purchased it even though I spent weeks researching and watching YouTube videos before buying. My opinion is the Sr and Sr+ will be allowed to charge faster. It's just a matter of time.

I hope you're correct. The faster charging speed is the ONLY thing that I wish my car had vs. the LR models. Everything in my car is perfect and I absolutely love it.

As Elon would say, you'll frag your battery. Standard range will never be able to charge as quickly as long range, but I think there is still room to speed it up some more.

If a 75kWh battery (LRM3) can charge at 250kWh, then by that logic, the SR should be able to charge at ~165kWh (assuming a 50kWh battery). However, perhaps it's more complicated than that.

That depends on if everything else remained the same. For example they might have modified/simplified the cooling system in the SR so that it can't remove heat as quickly and that is limiting the charge rate.

Perhaps, but there's also less heat to remove as the battery is 33% smaller.

Standard range absolutely should eventually be able to charge as quickly as long range. They should both be able to charge from X% to Y% in the same amount of time. I think this is the only thing people are waiting for here... a profile update for the SR to allow this.

Nobody should expect the SR to charge at the same power as the LR though, and I haven’t seen anyone here saying they expect that. They just want it to charge faster than before, like they’ve done so far by increasing the speed on LR.

I‘ve recorded a timelapse on a new SR+ european version with the CCS connector on a Tesla supercharger in Germany.

At the end of the video there are some charts showing more data, sorry all metric though.

Try again at a lower starting SOC, say 5-10%. You'll be impressed with how much charge you get in such a short time and the lower SuperCharger cost ... it it is tiered rates.

Plotted the recent @karki and @Joerg data below. The data from @Joerg provides additional evidence that the 2019.20.x SR+ charging profile is now limited to 100kW, a small decrease from the 105+kW seen previously. This makes the SR+ c-rate consistent with the LR cars when the LR cars are on a 150kW V2 Supercharger. I lowered my 19.20.x prediction line appropriately.

It looks like both the @karki and @Joerg batteries were not quite warm enough to sustain the latest possible taper, but more charging session examples are needed to be more definitive.

 

[momo3605]

Why do we expect that the SR+ and LR should charge X% to Y% in the same time? Normally wouldn’t you expect a smaller battery to charge faster?

 

[Joerg]

Actually I would expect the same amount of time to charge to full assuming you charge both batteries (smaller and larger) with the same C rate. Since both packs use same cell types and same module cooling there would be no need to reduce C for the SR+.
But same C rate for both packs of course doesn't imply the same power (kW) while charging - and still both packs would be at 100% at the same time.

But anyway - for me it is all about how much range I get in a certain amount of time before the power is reduced too much.
On the SR+ for me the sweet spot for charging is roughly between 10% and 50-60%, i.e. 20-25min charging for adding 140-160miles. Plenty fast and the next supercharger already in range.
On our X100D (2017) the highest mph rating we get while charging is 312, on the SR+ it is 460 - amazing and all because of far better milage efficency.

I've tested this in my long range car vs my roommate's mid range car. They charge at the same C rate and charging time from 10% to 80% is the same. Obviously, fewer miles are added to the mid range car for the same period of charging.
