TESTED: 150KW VS 180KW VS 350KW WITH RIVIAN R1T - DOES IT SAVE TIME?

EV Channels Review

This video thoroughly tests the charging speeds of the Rivian R1T across various Electrify America and EVgo charging stations, ranging from 150kW to 350kW. Contrary to expectations, the results showed minimal time differences (less than 2 minutes) between the different power outputs when charging from 3% to 85%. The reviewer highlights that the Rivian's charging curve appears to target a consistent average speed, adjusting power delivery to meet this average rather than maximizing peak output. This suggests that for typical road trip charging sessions where drivers might unplug between 70-80%, the specific charger's rated power has less impact than anticipated. The reviewer advises that for shorter charging stops (30-40% SOC), higher-powered chargers offer a benefit, but for longer charges, the difference is negligible. The video also notes the unreliability of charging time estimates displayed by the vehicle. Overall, the R1T's software manages charging to provide a predictable experience, simplifying the process for the user.
