This is why I tried to make it simple for non-engineers. The average person only cares about how many minutes they need to charge to get to the next charger. If I want maximum mile/kw or minimum kw/mile, then I would not get a big truck like Rivian or Hummer, I would get a small 2 seater. But that small 2 seater will have a much smaller battery and thus charge at a slower rate, but will not necessarily give me better time to add 100 miles. It could take more, less or the same time to add those miles.Your bio says you are an engineer. This should all be second nature to you.
Many car makers are now advertising X miles in Y minutes, rather than charging rate. And yes this assumes the maximum charging power is avialable, but we see the world moving to the CCS limits. Rivian is now stating 140 miles in 20 minutes, GM has stated 100 miles in 10 minutes for Hummer and 100 miles in 30 minutes for the Bolt. I like this metric because it is simple, and yes I do understand if I use a low power CCS at 50KW that goes out the window and is not achievable.
My baseline for comparison will be if I take a long trip along freeways, which have 350KW EA chargers along the way, which vehicle will provide the minimum minutes I will need to charge.
