Yes, I can keep going. So the 350-kilowatt charger from Porsche, like if they had mentioned they’re rolling that out, on the lab call, J.B., you seemed to indicate that you guys were sort of going to keep the status quo with your Supercharger technology. But Elon, I know you’ve mentioned that there is a V3 Supercharger, so I’m just trying to get some clarity on whether you will be improving your Supercharger technology or not and if there is a V3.
Elon R. Musk
Well, we’re definitely going to be improving our Supercharger technology. The thing about a 350-kilowatt charger is it doesn’t actually make a ton of sense unless you’ve got a monster battery pack or have like a crazy high C-rate, in which case your energy density is going to be poor. So it’s kind of cockamamie. Yes, I think maybe 200 — on a — also I don’t know if you meant 350 kilowatts for a single car. That’s really pretty — you’re going to frag the battery pack if you do that. There’s no — you cannot charge a high-energy battery pack at that rate unless it’s a very high kilowatt-hour battery pack. So something along the — yes, I think — J.B., like a couple hundred — 200, 250, maybe…

Yes, I mean, that — that’s definitely sort of power level that we’ve discussed and explored. And some of it also comes down to an optimization around utility versus cost and trade-offs in the car itself. You kind of hinted at that, Elon, but there is a trade-off fundamentally between charge speed and essentially range or cost of battery. And we look at that pretty carefully. We understand the trade-off, and we could design cells in the pack that could charge it faster than 300, 400 kilowatts. But it’s not a very useful trade-off to the customer. That’s…

Let’s go to understand the difference between energy and power even, really. Energy — obviously, energy’s rate is essentially, at most, a range. And then power is kind of like your peak acceleration basically, the rate at which you consume energy. So really what — it’s more important to have long range than it is to have a superfast charge time. And you can sort of think about this in the devices that you use. Like would you rather have a cell phone that lasted 2 hours but had — it could charge in 5 minutes or 10 minutes, let’s say, but only lasted 2 hours. Or you’d like a cell phone that lasts 2 days and maybe takes 1 hour to charge.
