This seems silly. I've been on many trips over the past six years, and wherever SCs are the normal distance apart, charging time is about fifteen minutes. That's just about enough time for a pit stop and getting a drink. As the V3 rolls out, even where there is a missing SC, it's still going to take 15 minutes. Because Tesla charges for every idle minute you're plugged in, an 800V charge will cost a bunch or you will have to stay with the car while it charges, increasing your charge time. My opinion is that Porsche just did it because it makes the specs look better. Practically, there's little value added.
Let's get our perspective right.
Goal is to get everyone on zero emissions ASAP, right? Well, people refrain from going BEV due to theoretical corner cases. It's how the mind works.
In 15 minutes, a Model S on V2 before update may gain just over 25 kWh. Good for about 125 km on the highway, just about an hour in most countries. And there may well be a next SC then.
People don't want to change their routine. It's not even a corner case to driver 2 hours between leg-stretch-potty-breaks. And I've seen 15 minutes to be quite average. So double the charge rate is called for. And you cannot always be right at 7% SOC coming in, so actual charge gotten over 15 minutes (especially with shared charger) is likely less than 125 km worth in today's reality.
It may seem like everyone and their sister are buying BEVs but in the grand scheme of things, they're still extremely unknown and frankly, most people can't afford it, nor charge at home.
Even if most people can't buy Teslas and Tesla will nevver rampup enough to make enough cars even if they can afford to give them away or make available as cheap robo taxis, an appealing Tesla will boost the rest of the market to step it up.
So it's GOOD and NEEDED for Tesla to go for a best effort.
Also, and most BEV fans refuse to see this in the eye... High charge rates at the cell level allow for smaller batteries, more affordable cars to WORK for actual people looking to replace their super average petrol car, which are a majority of the market. And personal transport emissions. An econobox with even 1/3 the battery size of the Porsche Taycan, same cells, charging at 4C most of the way, will get 150 km or so per 15 minutes. And that makes it doable for Mr. Everyman. Now all he needs is for it to work out financially, but Mr. Everyman doesn't have money in the bank and zero discretionary spending after clothing, car and holidays. Give up holidays to own a BEV?
