By how much would using the supercharging feature reduce the overall lifetime of the batteries? Lithium cells aren't immune to the memory effect, which would only be shortened with the high heat associated with pushing a significant amount of power through the car.

Hopefully not significantly. Most damage occurs over the 80% mark, and it sounds like they have optimized the newer cells for this speed

Dear Elon. Call me about setting up solar roofs in South Africa. Best regards Phillip

Johannesburg has some strong motivators for solar energy (in whichever incarnation) such as:

1. Sunshine days

2. 2000m above sea level (for photovoltaic efficiency)

3. Many power interruptions and "load shedding" by state owned utility

4. Enough private (and government if they were better managed) money

5. Human capital and good universities

6. Enough physical space

I think there may be more reasons, but these are some of the main ones.

The much bigger news is they completely walked back FSD (full self-driving) into something that you have to monitor at all times by changing the description on their website. The release of a proprietary charger is somehow completely overshadowing that news. It's changed from driving itself around in a ride hailing network to earn you money while you sleep, to now making you always be in the car and pay attention and…

They run in shadow mode to gain statistical data, and I believe when actively used they can send more detailed data around disengagements.

I bet of they allowed people to opt in, at least a huge minority of Tesla owners would jump through hoops (like login and recaptcha) to contribute data if it advances the science.

Tesla Model S owner here. By choosing spots and times strategically I've gotten nearly 400MPH charging at the existing stations and the difference it makes to convenience is amazing. Super looking forward to 1000MPH! At that rate I can likely make it to Squamish BC, from Seattle, and back, with only one ~20 minute charge in between. That's still about 4x or 5x for the time I would spend filling an ICE car, but gettin…

Yeah, this is closing the gap in a significant way. It's still not "charge on the way to work" fast, but it wouldn't be a painful delay on the way home. More important, it's an improvement . I still switch back and forth between my Model S and an ICE car--I can't remember a time when the gas station experience ever got better .

One of the big benefits of electric in my view is that you can just let it charge overnight in your own garage. There's simply no need to charge on the way to work. (Yeah, this only works if you do have a garage, but that covers a lot of people.)

Earlier quoted context omitted.

At 250 volts, it is only 1000 Amps. Normal houses come with 200 Amp service. Older ones may be 100 Amp, and larger modern ones are 400 Amp. So that is about 5 houses. You could buy that service. I hope Tesla would sell you the supercharger for it.

No, you can't buy that service. Not even close. 400amp service is usually 2 200 amp panels. Done with 2/0 cable. It's rarely, if ever, 1 400 amp panel. 1. There is no way you would get "1000amp service" at 250v. It would be a minimum of 480v 3 phase (and not 1000amp). You may even want a lot higher, because as you'll see, getting that many amps is ... very very hard. 2. You can't even buy 1000amp cable gauge anywhere…

A new 1MW power cabinet with a similar design to our utility-scale products supports peak rates of up to 250kW per car.

Somebody is buying this service. It's probably delivered more in line with your reasoning here.

What does this have to do with the memory effect? The memory effect is about never discharging NiCd/NiMH batteries beyond a specific point (hence old recommendations about occasionally fully discharging your battery), it has nothing to do with fast charging.

I think you're confusing the next incremental step toward FSD with the end state of FSD. Tesla changes its marketing materials and web site copy all the time, but the Master Plan Pt 2 post (which outlines what you're alluding to) remains unchanged. Additionally, just three weeks ago, Elon was on the Ark Invest podcast claiming FSD will be safe enough for a human to sleep at the wheel by end of 2020[1]. I don't think…

Can you speak more to this? Similar situation. Interested in a Tesla but live in an apartment without a station but during winter have well below freezing and sub zero temps. Seems difficult.

I've gotten used to it and do just fine not being able to charge at home. I have chargers at my work but still choose to mostly use the nearby supercharger. When I would use the supercharger on cold mornings, it would charge at 0mph for 10-15 minutes and then slowly increase. The worst I saw was it stayed at a rate of 25mph for over an hour before I finally had to leave. However, using a regular wall socket has consi…

Are you at all able to pre-warm the car, like when you wake up and have breakfast, so it is ready to go?
