2024 R1T Large Capacity Higher Than Expected

[mika2]

I picked up a 2024 R1T Large Performance (22" Sport) from the shop about a month ago. I finally got around to hooking up ABRP and noticed my battery capacity is being reported as 138.4 kWh. This is quite a bit more than the 131 kWh capacity documented by Rivian and a bit lower than the 141 kWh capacity of the Max pack. Setting charge limit to 100% estimates 341 miles which is in line with the range for the Large pack. Any idea why the capacity would be reported that much higher?

It's a gated MAX Pack - I bet you can pay to unlock the rest - or I''ve seen that in some other threads.

I thought the Large+ pack was for Gen 2?

The large pack is actually a 141 kwh pack (gross) with 131 usable when new. Max pack is large and has about 142kwh usable...not sure on the gross capacity.

All EV batteries, as you may know, have a buffer on the top and bottom to keep the pack healthy. With large Rivian initially only allowed 126 kwh to be usable but later opened up another 5 kwh via an OTA software update.

than there is this which is for gen1. My numbers were taken from EPA docs. I also have pics of a large pack out of a truck and its label.

Not sure why ABRP is reporting something a little different. 341 is the correct range for a dual performance on 22" sports.
