TESTED: DID RIVIAN FIX CHARGING THERMAL ISSUES IN 2023.2.3? WITH CAN DATA!

EV Channels Review

This video tests Rivian's claim of fixing charging thermal issues with software update 2023.2.3. The reviewer, Branden Flasch, compares charging sessions from 10-70% on the old software (2022.47) versus the new update, using CAN bus data for detailed analysis. While the new software shows improvement, the fix is not a complete overhaul. The reviewer observed that the new software allows the vehicle to hold peak charging speeds for slightly longer and results in a less drastic power dip when battery conditioning is triggered. The average charging speed from 11-70% improved by approximately 3-4%, saving about a minute on the total charging time. However, the core issue of thermal derating when the battery reaches around 50°C persists, with the cooling system still struggling to manage the heat gradient effectively. The reviewer concludes that while the update offers a marginal improvement, it doesn't fully resolve the extreme thermal derates, suggesting that further hardware or more significant software changes might be necessary.
