Initial 75 kwh? Don't think so.

[Petra]

What was the biggest battery when the S came out? What was the battery size when the first dual motor P version debuted?

85kWh is the answer for both questions.

 

[Runt8]

Any chance they will all come with a 75kWh battery, and it will be an option to enable longer range (like they did for the S)? Or does the price point preclude that option?

I've got to believe it's a lower chance given the tighter margins.

60 and 74 KWh? Tesla invests $216M into Model 3 battery production line at Gigafactory 1

60 and 74 KWh? Tesla invests $216M into Model 3 battery production line at Gigafactory 1

likely a typo, in context he says:

which is slated to be 74kWh, and likely badged as a Tesla Model 3 75.

The batteries don't need to be smaller to have reduced performance for non-P cars. The controller takes care of that in its programming by allowing less amps to dump to the motor at full throttle.

I consider 75 the MINIMUM acceptable battery size for upgrades, for what Tesla will likely charge for the big battery, going from 55 to 70 isn't enough of a difference. It'd be nice if they surprised us with an 80 or 85 battery.

I kind of feel like Elon shot himself in the foot a bit by telling everyone that 75 was the largest that would physically fit. If there isn't a 75 available at launch, people will be upset and potentially cancel their orders to wait for the larger one. If there is one available, then they've lost the ability to increase it in the future like they have for the Model S.

I personally think there will be a 75 at launch (or shortly after), and possibly a couple years in the future a "reconfigured" battery pack that allows for higher capacity in the same space.

Im sure all options will be available to configure the first day they allow you to build your order, your just going to be waiting longer if you choose any of the options they are delaying until later in production. This will keep people around and prevent reservation holders from canceling.

I really hope this is the case.

My thought with this was that Elon has given out the upper limit of battery size, so now there's no way they can have a slow march of progress like they did with the Model S.

 

[Model 3]

My thought with this was that Elon has given out the upper limit of battery size, so now there's no way they can have a slow march of progress like they did with the Model S.

The "slow march of progress" from 85 to 90 was not in putting in more cells, but a new chemistry. From 90 to 100 they found a new way of packing the cells into the battery and still be able to cool them, so they could put in more cells. (Not sure about any changes to the chemistry?) No, they did not "hold back" earlier, it was advancing technology, and so it will be when they make a "slow march of progress" on Model 3 from 70/74/75 or whatever up to the next sized battery pack.

Regardless of how they increased the size, they never came out and gave an upper limit. I never said anything about them "holding back." All I'm saying is that there will be people who buy the 75 thinking it's the upper limit. If Tesla starts coming out with larger ones in the near future those people are going to feel like they were lied to.

Lied to? The original tweet said:

The shorter wheelbase only allows for a 75 kWh pack in Model 3 at current cell/module energy densities

Do we have reason to believe he's lying about "current cell/module energy density"? If not, then I dont see how anyone could possible think a larger pack down the road would make him a liar.

There will always be people that don't understand that technology progresses and that what wasn't possible one day may well become standard the next. And there are also people that understand that fully and will want to make a big deal out of it anyway. Most reasonable people however, understand that things change and that constantly waiting for the "best" means you'll never purchase anything.

Wow, I totally missed the part about "current cell/module energy densities." You are absolutely correct, there's nothing in that statement that precludes improved, higher density batteries.

A 70 kWh might not get the magic 300 miles range... that would be a mistake.

Pshhh, just do you testing downhill with a tailwind.

Assuming the 75kwh battery and that 70kwh is useful, you've got to get the car down to 233.33 watt hour per mile. That's pretty low.

 

[Foxhound199]

Everyone's assuming that they are going to badge the 74kWh as 75, and all I'm seeing is a comparison slide from Tesla showing the Model S as sporting a prestigious 75 kWh, while the middling Model 3 limps in with a ho-hum 74kWh.

Depends what they actually put in there. the P100D for example has 102.4 kWh with 98.4 kWh useful out of the labeled 100 kWh.

Most EVs in that price range, weight, and size are hitting around 4+ miles / kWh.

I would estimate that even the base Model 3 might have a greater range than the Chevy bolt due to lower drag coefficient. If this is the case then if usable capacity is close to 75 kWh we should still see 300 mi easy.

 

[gregincal]

Can't say I agree with that thinking. He needs to hit that $35,000 promise and that means offering the smaller battery to start.

Offering is not the same as building. I still think they will offer all options at start, but some configuration will be build later.
