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.

> 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

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.
