I just read that article earlier this morning and was shocked they did not say how much battery power the climbs used. Without that information it is all fluff. Guess they didn't want to say.
Watching the video I was able to glean some data that gave me an idea of how much power that thing was using- at one point in the video the engineers were mentioning that they might be pulling 1200 amps for a minute or two at at time. At another point it was mentioned that they were charging to a max voltage of 440. That works out to 528 kw. Assuming they were running 60 mph, that's 8.8 kwh per mile. The maximum range Rivian truck has a 180 kwh battery. So at the flat out maximum towing power draw you are depleting your battery in just 20 miles. By comparison, take a Ford Ecoboost powered F150. Say running flat out in a hard loaded climb it gets 3 mpg. So, it's fuel lasts about 100 miles at the fuel consumption rate. Disclaimer- I'm not an engineer, so if anyone sees an obvious flaw in my math, call it out and my feelings won't be hurt.
