It does not go down to 15kw.

At old Tesla stations it went from 150kw to 75kw.

Any v3 station (first introduced in 2019!) will stay at 150kw to 250kw. I haven't seen a v2 station in 2 years now.

You also don't need a battery based on its age, you need it based on its mileage. Some people like my wife only drive 8k miles a year, which is more around 20 years...

> It does not go to 15kw

It goes to whatever the software tells it to, which is based on the following factors:

- What percentage the battery is at when it starts charging

- Environmental conditions (cold/heat)

- How many other cars are being charged (IIRC most super charger stations don't supply the max amps * the number of ports - they assume some cars will be throttled)

A v3 can get up to 250 kW but only under optimal conditions. The more EVs on the road, the less optimal it becomes.

True, but for reference, "Tesla also provides an 8-year warranty (or up to 150,000 miles, depending on the model) for its batteries, guaranteeing at least 70% capacity retention during this period". The average consumer doesn't understand that their car gets less range over time after use.

right, the average consumer never owned anything which runs on a battery before and those rare folk that might have owned like a cellphone surely think that cars have MAGIC batteries which unlike every other battery they have ever owned is going to be rock n roll for decades

Cellphones didn't previously run on gasoline.

you used to have to roll the windows down with your hand but people are somehow managing to push the bottom now to do the same :)

Dude you're flat out guessing about how they work, and you're embarrassingly wrong about the results. V3 Superchargers reliably output 250kW every time you pull up. Their power sharing between cabinets ensures this. Environmental conditions don't affect them due to very efficient thermal management and preconditioning.

They explicitly said this about their new V4s:

> Posts can peak up to 500kW for cars, but we need less than 1MW across 8 posts to deliver maximum power to cars 99% of the time

If your EV battery isn't pre-conditioned for cold driving, it can and will get down to low double digits. That said, it's only an issue in winter and colder climes.

OPs comment says - if theres too many cars it goes down to 15kw.

That has nothing to do with conditioning.
