Long time lurker, first time poster. Saw the release notes for this on reddit. rexorz got invited to tonight’s event leaked the news.

Supercharging V3 supports 250 kW on the Model 3.
Summon over keyfob now supported.

That's nuts. I can't wait to see some pictures of that actually happening.

 

[PoitNarf]

Very interesting!

 

[commasign]

So, extrapolating "half the time" = 100% charge in about 30 minutes, 80% charge in about 20 minutes, or 170 miles range in 15 minutes???

Does that mean using a key fob you can summon without data connection (like in a underground parking structure)? If that’s true then I can start considering to buy a key fob.

 

[SoCalGuy]

More importantly, has this started rolling out en masse yet?????

This appears to be the case, yes.

That's amazing. I don't understand how they can make it faster at more than 50% SoC where we're already limited to less than 120kw...

The item that really caught my attention was:

"Also, when you navigate to a Supercharger, your car will condition its battery during the drive, so it can charge faster."

This is something that several people have been requesting over this winter. I like that it's automatically triggered simply by setting a Supercharger as the destination. I'm assuming that's the case when Trip Planner inserts a Supercharger stop for you automatically.

Yeah, definitely want to see what the new curve looks like especially as you get close to 100% full.

I don't believe this will actually cut your charging time in half. They are probably playing loose with their words. It may on average be able to service 50% more cars, assuming a fully utilized SC, but it is not cutting your charge time in half for the best case (30 minutes from 20% to 80%). The first clue is they cite the fact that dedicated vehicle charging is partially responsible for the shorter charging time. This should have no effect when comparing the fastest possible charging on the V2 vs. V3. Second they may have adjusted the charging curve on the Model 3 slightly, but that would apply to V2 and V3. Currently, peak charging is only achieved from about 20-50% SOC. V3 would likely peak for 25-45%. So you are only doubling your power for this 20% range. The kW would be identical for all other SOC.

The real value of V3 is it will double your worst case warm battery speeds which occur when you are splitting the power with your neighbor.

Also wondering it they will limit you to 80% charge. Makes no sense for a car to hog a v3 charger from 80%-100% especially when there's a limited number of v3 stalls available.

 

[ElectricLee]

This is great news, what is the roll out dates for V3

Based on verygreen's firmware snooping, looks like it.

Source?

I don't believe this will actually cut your charging time in half.

That is probably only the case when you were on a paired V2 stall.

The one thing we can be certain of is that it will not be nearly as good in reality as Tesla makes it sound. It will be a welcome improvement though. It'll be interesting to see what that taper looks like!

 

[sreams]

It probably *will* be double... on average. Charging is slower at v2 sites when chargers are occupied.

 

[Chancellor32]

The real question is when will V3 be at Superchargers between Cali and AZ? Lol

That's the million dollar question IMO - have they shifted the point at which power starts to taper off. If so, this is HUGE.

It would mean they essentially can get more throughput for the existing V2 chargers by letting people with the compatible battery chemistry (i.e Model 3) taper later and charge faster.
