Charging Insights

How their charging profiles differ

The Rivian R1S (135 kWh) and Rivian R1T / R1S (Max) present different charging characteristics primarily driven by battery capacity and maximum charge limits.

Battery Capacity: The Rivian R1S (135 kWh) features a 135 kWh battery, which is 9% smaller than the Rivian R1T / R1S (Max)'s 149 kWh pack. A larger battery offers more driving range but takes proportionally longer to charge at standard charge rates.

At-Home Charging (AC): Both vehicles share the same maximum AC onboard charger rate of 11 kW. This means they will draw the same maximum power from home wallboxes.

On-The-Road DC Fast Charging: The Rivian R1S (135 kWh) accepts up to 220 kW DC, while the Rivian R1T / R1S (Max) supports up to 350 kW DC. The Rivian R1T / R1S (Max) has a faster DC limit of 350 kW, allowing it to charge faster on ultra-rapid chargers, assuming the station can supply the max power.

Rivian Recommendation

For the Rivian R1S (135 kWh), a standard 7.4 kW home wallbox is ideal for overnight charging. If you travel long distances frequently, look for DC fast chargers capable of supplying at least 220 kW to minimize charging stops.

Rivian Recommendation

For the Rivian R1T / R1S (Max), a 7.4 kW home charger is also the perfect fit. Since it supports up to 350 kW DC, you will achieve optimal highway charge times by planning stops at charging stations rated 350 kW or higher.

Best Home Chargers for Rivian R1S (135 kWh)

We analyzed charger speeds, compatibility, and durability to select the top home charging stations that match the specifications of the Rivian R1S (135 kWh).

Optimal High-Power AC Charging

Your Rivian R1S (135 kWh) supports high-speed AC charging up to 11 kW. To charge at maximum speed at home, we recommend a 48-amp charger (like the Tesla Universal or Emporia) hardwired to a 60-amp circuit. A standard 32-amp charger will still charge overnight but won’t take full advantage of your car’s faster onboard charger.
