RIVIAN IMPROVES RAPIDGATE DC FAST CHARGING THERMALS, BUT MORE WORK REMAINS

EV Channels Review

This video investigates the impact of Rivian's software update 2023.10.02 on the R1T's DC fast charging thermal management. While the reviewer notes that many Rivian owners report improved charging performance and earlier battery cooling activation, his own experience with his nearly 30,000-mile R1T showed mixed results. Unlike previous versions where charging would drastically drop off or even shut down due to overheating, this update resulted in a smoother, albeit still significant, derate to around 100 kW. The reviewer observed a delayed activation of the AC compressor for cooling, leading to a prolonged period at reduced charging speeds before power eventually increased. He expresses frustration with the lack of detailed temperature data within the vehicle, making it difficult to diagnose issues. While acknowledging potential improvements for other R1Ts, the reviewer's specific vehicle did not exhibit the dramatic improvements reported by others, leaving him with the impression that while different, the charging performance is still not perfect, especially for long-distance travel and towing.
