Tesla battery swap: Post announcement discussion

It sounds to me like the purpose of swappers is more for marketing than for actual use. To speed the transition to EVs among those who are not early adopters, they need to be equal to or better than ICEs in every way. As a practical matter the swappers may get little use as people just choose to wait for a supercharge, but that might not be as important as being able to tell potential buyers the rapid swapping option exists.

Yes, that's how I see it.

Also it gives Tesla 7 ZEV credits instead of 4 credits per car as battery swap satisfies the fast refueling requirements.
 
Impressive technical solution to a problem which I`m not convinced really exists.
I wonder if this is more about demonstrating the versatility of the Tesla platform to other manufacturers.
As EV systems go, Tesla now provides far and away the most complete package. Drivetrain - Chargers/Superchargers - and now Battery Swapping
 
Half a million for each swapping station. Is that comparable to a basic no frills gas station, with its underground tanks and pumps?

Depending on location and size, gas stations are $500k+. In the bigger cities in California, gas stations are $1 million easily (land not included). Gas stations on the road trip corridors are probably just as expensive because the land owners know that travelers have no other choice but to fill up so they can charge gas stations owners more because of the guaranteed business. In turn, gas on road trips from SF to LA are 1.25x-1.5x the cost.

That's the #1 reason for sure, and why not?

The #2 reason is to silence critics of slow recharging and #3 is marketing.

All that and maybe it will help the vast majority of the World car driving population who don't have a garage at home. :)

All good reasons IMHO.

Is the video up yet?

They are already getting full ZEV credits for the 85kWh model. The swap concept was demonstrated in 2009, I believe. (With a group of technicians). There are documents published from the state of New Jersey that showed that the 85kWh was classified as getting full credits.

From another thread:

http://www.state.nj.us/treasury/taxation/pdf/Treasury2013ModelYearZEVlisting.pdf

The above link shows that Tesla Model S 85 kwh is a type V (5) vehicle. Type V vehicles must meet fast refueling requirements (per http://docs.nrdc.org/energy/files/ene_10070701a.pdf ), and are worth 7 ZEV credits.

The Air Resources Board of Cali held a recent public meeting on tweaking the ZEV regulation. One of the things they are changing is disqualifying battery swapping as "fast refueling". I asked them if anyone was making cars that were currently getting ZEV credits from battery swapping. They said yes. I can't think of who this could be other than Tesla, though this wasn't specifically confirmed, and I didn't specifically ask.

So these two things make me think Tesla is already getting 7 ZEV credits for the 85 kwh.

This is just from my own research. Not an expert on this, so maybe someone will contradict me.

I think the main purpose of the battery swap technology is for flexibility in the future. If they come out with a 150 kWh battery in the future, this will be a convenient way to borrow one for a road trip or even upgrade if you want. It also makes it possible to sell a base model GenIII car with less than 200 miles of range and still allow it to go on road trips by borrowing a larger battery for the trip and then returning it on the way back.

I suppose it would also shut up all the people that think a 30 minute charging stop on a long road trip would be an extreme inconvenience. But I bet those people would probably tend to choose the free 30 minute charge over the $60-$80 battery swap most of the time if they actually take a Model S on a road trip.
 
Don`t get me wrong, I think the system is brilliantly executed (even though I was hoping for a frunk-based battery).

But you`re right, this is more about silencing critics AND burying Hydrogen.

Plus it does look promising as a Battery Upgrade system.

Imaging driving away from the SwapStation and suddenly noticing that your Ideal Mile rating is up to 400?

Absolutely, this will drive sales because it gives people an option back that they have now. Elon said they were going to measure how popular this is before they roll this out nationwide. By popular I hope he means how much sales it drives rather than how much actual usage of the system there is.

I just wished it was closer to a 10 gallon fillup instead of a 15 gallon one (24mpg equiv instead of 16mpg equiv).
 
I wonder what the tolerances are here. Obviously the jig must be able to line up with the bolts with accuracy up to a 1/16". However, you can't possibly drive & stop your car that accurately - even just tire pressure differences will cause a larger misalignment than that, as well as approaching at a slight diagonal.

So I assume the jig must have the ability to move on the X and Y axis a bit as well, as well as having the ability to rotate by a degree or two?
