The Rivian R1T is the next all-electric vehicle that we will analyze in terms of fast charging capabilities.
Data for the analysis comes from one of Kyle Conner's test, for the Out of Spec Reviews channel, performed at an EVgo fast charging station.
It's not necessarily the perfect charging session, because according to the video, the battery was a bit cold, but it shows a full 0-100% state-of-charge (SOC) range. The results are better than achieved in a short TFLEV test.
