The Rivian R2 And R3 Probably Won't Be 800-Volt
Briefly

RJ Scaringe emphasized that while an 800-volt architecture is beneficial for larger batteries, for Rivian's smaller R2 and R3 models, it is "just not as critical." He explained that battery chemistry plays a more pivotal role in performance for these models than voltage levels. Therefore, Rivian is focusing on optimizing costs and pricing to deliver competitive performance, rather than pursuing the higher voltage for smaller vehicles.
Rivian CEO RJ Scaringe pointed out that achieving fast charging speeds with a 400-volt system is possible, stating that this architecture can provide sufficient charging efficiency for the R2 and R3. Despite industry trends leaning towards higher voltages, he emphasized the importance of balancing cost, performance, and battery chemistry for Rivian's forthcoming smaller vehicle models.
