Samsung’s 20-year-life EV battery runs 600 miles on 9-minute charge

So about 1 megameter.

There's a good chance you are mistaken. It was not specified which type of mile they are referencing.

The only sensible mile to use would be the Scandinavian mile (10.000m). = 6000km range.

Another possibility is the nautical mile (1852m). = 1.111,2km range.

And there are plenty of other "miles" to choose from.

Mm!
