Roadster 3.0

[JRP3]

Just an update on this. While the driver side blower fan was pretty clean, the passenger side was full of leaves and other organic stuff. I blew it out completely and now my car is quiet once again. Yeah!

Have you considered putting a filter over the intake?

Have you considered putting a filter over the intake?

Yes, I've been considering it. But the requirements are pretty high:

1) Can't reduce airflow
2) Can't just itself clog up easier/faster than the fan
3) Needs to be cleanable as easily as the fan (I can reach it without removing wheels with a $7 extension I bought for my compressed air gun.
4) Needs to be securely installed, but removable when needed.

Right now #3 is prompting me to do nothing but check it every month or two with a flashlight.

My 3.0 v1 is on FW v5.1.2 and I’ve never seen the voltage on ESS SOC screen >4.1v on standard or range charging.
I wonder if tesla SC would update the FW to v5.2.0 for my v1 3.0 ESS? I assume there’s improvement over v5.1.2.

Here is brand new 3.0b pack charged to 99% in range mode. For those who thinks 3.0b packs are different... Still charge up to 4.35v like old LG cells from 3.0a pack. It doesn't sounds good.

Good way to degrade a cell unless they have some new chemistry magic.

I'm hoping that guy who's working on using Model S batteries for a Roadster pack is successful. I don't trust Tesla with coming up any sustainable solutions.

iphone batteries all use these higher voltage cutoffs, and they all have predictive degrade curve over use. You can see the delta voltage difference here in mah.

I'm also working on a battery sheet replacement/refirb, as cells will be replaceable if they do go bad in a brick.

As you can see at 4.20V charge we lose about 13-14% of the capacity and 14-15% of the energy, but undercharging is a good way to increase the cycle life by hundreds of cycles.

Are people still able to get a new 3.0 battery from Tesla? Not much has been said here recently. So I hope Tesla is still making the battery packs for the Roadster. The reason I ask is I do miss my Roadster and who knows I may end up getting another.

I'm currently in line for one, as of July 6th. They said 6-12 months for it to be assembled and ready for installation. From what I understand, you can't just order one because you want it. It's only available as a fix to a dead or dying pack. They no longer do sheet swaps on original packs. After almost 15 years on its original pack, my 1.5 had a brick go bad (while charging on 120V in 100F+ degree temps FWIW). It seems that once one brick goes, others are soon to follow. So instead of paying for a 3rd party sheet swap or cutting out the bad cell(s), I decided to go R80 and get a fresh start.

Yes, last month they replaced my Roadster battery with the new one after close to 3 years.

Because the car stood so long, it needed a break job and new tires. Now all is well.

Total invoice was 34,700 EUR plus change.

Yes. A friend of mine just got his new 3.0 installed earlier this month and another friend just got confirmation that they are ready to pull his pack to rebuild his new 3.0.

How long did they have to wait from the time they reserved a slot?

How long did they have to wait from the time they reserved a slot?

I believe that priority goes to cars that don't run so the time wait varies with the type of demand.

I wonder if the new 3.0 packs will die after a few years like the original 3.0 packs did.

Are the 3.0 packs more sensitive to cycles, temp, or time than the originally-included packs?

In terms of CAC, it's almost entirely time (see the long 3.0 Longevity thread where I collected data). I don't have enough information to figure out what correlation there is with their just dying like they have been, but the rumor mill says that it's all the early ones that have been dying. If it was cycles then you'd have expected mine to go much earlier, since I drove it much more than any oner one of which I'm aware, but that didn't happen. If it was temp, on the other hand, you'd expect mine to last longer since I'm in cool Seattle, but that also didn't happen. So my guess is just time (or maybe time + the batch of cells). But that's just a guess unlike the CAC result, for which there was solid data.
