Rivian R1T / R1S Large Pack (2024 Gen 2) Charging Curve & 10–80% Fast-Charging Time

The Rivian R1T / R1S Large Pack (2024 Gen 2) achieves an official peak DC fast-charging rate of 220 kW and typically charges from 10% to 80% State of Charge (SoC) in 31.3 minutes when plugged into a compatible high-power DC dispenser with a fully preconditioned battery pack. During this standard session, it takes on approximately 76.3 kWh of usable energy, adding roughly 231 miles of driving range. Charging speed is heavily governed by initial pack temperature, starting battery SoC, dispenser amperage limits, and the vehicle's internal Battery Management System (BMS) thermal step-down curve.

Vehicle-Specific Charging Insights for the Rivian R1T / R1S Large Pack (2024 Gen 2)

Where Charging Begins to Taper

Holds 215–220 kW from 10% to 32% SoC, tapering to 130 kW at 60% and 65 kW at 80% SoC.

Where the Session Spends Most Time

Charges 10% to 80% in approximately 35 minutes for its 109 kWh pack.

Recommended Road-Trip Charging Strategy

Arrive at 10% SoC and unplug around 65% SoC (~22 minutes) for fastest overall progress.

Key Environmental & Thermal Factors

Gen 2 zonal thermal architecture improves heat dissipation during sustained high-current charging.

Trim & Battery Variant Comparison

Max Pack is 141 kWh (410 mi EPA range). Standard Pack is 92 kWh (270 mi range).

Why Real-World Speeds Vary

  • 1. Cold-Gate Throttling: If the battery core is cold (<15°C), internal cell resistance causes the BMS to limit initial power to prevent lithium plating, adding 15–25 minutes.
  • 2. Cable Current Limits: Standard liquid-cooled CCS cables are capped at 500A. At 370V, this restricts 400V cars to ~185–200 kW regardless of dispenser capacity.
  • 3. Station Power Sharing: On paired or dynamic split chargers, total cabinet capacity is divided if an adjacent stall is occupied.
Data Disclaimer: Actual vehicle charging speeds and durations will vary based on ambient temperature, starting state of charge, battery age and state of health (SoH), active preconditioning status, charger hardware capabilities, and vehicle firmware version.
