Re: TSLA corporate outlook

Zero Motorcycles has a system that combines the worst attributes of both models: they rely on a relatively small number of motorcycle shops that carry Zeros as a sideline. As a result, if you buy a Zero and don't live near one of their Zero-certified dealers (or if you do but they stop carrying Zeros or go out of business), then you have to trailer your bike hundreds of miles for service and repair. The company itself does whatever it can to make contacting, or gods forbid, SPEAKING with them, as difficult as possible.

Re: TSLA corporate outlook

I agree with the above posters on the need for local or near support options however my point earlier was on the positive impact of separating the sales aspects of dealerships from the support & maintenance operations. The EVs requiring far less hands on maintenance under normal conditions will help make this transition easier over time. I might be overly naive on this topic of course and will see where we end up in next decade or so.

Re: TSLA corporate outlook

V4.... which seems likely will support 800v. Now I seem to remember a tesla fan boy on here saying 800v is all a scam.

Will he/she continue to say that if and when tesla also moves to 800v?

With the preliminary specs for the new Kia/Hyundais it's looking like 800v is going to be the future. Granted real world experience may vary. I think the race for solid state batteries is the next big one - I've got Toyota pegged for in the lead on that one but they are EV hesitant and starting it off in a hybrid which seems like a solid roll out strategy to see how well it fairs.

who would say that? I do not remember anyone discounting higher voltage as a good advancement for any EV. In order to charge faster it is necessary in order to keep current low.

I don't know who your 'fanboy' is but I told you that a 800v pack would not charge my Model 3 Tesla (or any EV of similar pack size any faster than 400v when the limiting factor is the C rate, and it is true. Physics are physics.

A larger pack, say one that is in a cybertruck, would benefit from a higher voltage pack because it exceeds the max Amps as it currently exists in Superchargers.


Speculation:
Tesla will have 150 kWh packs on the road, and 4680 cells may increase the C rate to ~ 1.8 average, 3C for short durations at low SoC.

1.8 * 150 = 270 kW
3.0 * 150 = 450 kW

A cybertruck from low SoC to perhaps 50% SoC may average 2.0C and will average 2.0 * 150 = 300 kW.

The current Supercharger peaks at 625 Amps IIRC but it may be more in the 500 Amp range sustained. That will require a 600v nominal pack. If the Supercharger can maintain 600 Amps then a 500v nominal pack would be spec'd. IIRC Tesla has spec'd Superchargers to 525v so that makes me think that the next Tesla jump will be to ~ 500v packs. But again: this is irrelevant to 80 kWh packs

Re: TSLA corporate outlook

There he is. Lol


Your assumption is that C factor is the only limiting factor. There are a lot of other parts in the system that can or could be a limiting factor during parts of the charging, which could benefit from higher voltage. I believe there have been a few teardowns now on the I5 pack, but I don't know if anyone has dissected the SK pouch cell Hyundai is using. Nor do I buy the idea Hyundai has setup their EVs to fail...

To me, Hyundai seems to have proven you wrong, but time will tell.

IMO, Hyundai/Kia is probably Tesla's greatest threat to US market share at this point with the range, price point, charging capability, and biggest one - build quality, service locations, and meaningful warranty.
