RIVIAN STANDARD LFP BATTERY PACK CHARGING CURVE FIRST LOOK! 0-100% DC FAST CHARGING TEST

EV Channels Review

This video provides a crucial first look at the charging curve for Rivian's new Standard ~92kWh LFP battery pack in the R1S. The reviewer emphasizes that this data represents the "gen one" charging performance, with a significant software update expected in July/August 2024 to improve it. The current test shows the LFP pack holding a consistent 200 kW from 0-25% state of charge, then tapering off, with a notable drop to 30 kW from 85% onwards. The total charging time from 0-100% was just over an hour, delivering approximately 100 kWh. The reviewer highlights the LFP's flat voltage curve as a positive, simplifying electronics integration, and suggests it might be the sweet spot for many buyers due to its potential for better thermal management and cycle life, despite its lower usable capacity compared to high-nickel packs. The need for LFP battery calibration is also stressed.
