What's New

A charging session can be derated for several reasons, and Rivian Roamer now surfaces those reasons directly on the charging session page.

Visible right on your dashboard you can now see your battery capacity, temperature and 12V status all in one place.

The most requested feature is now live for R2 and Gen 1 R1 owners: battery temperature! On the dashboard, battery page and session pages. Now gain insights into how temperature impacted your session!

On the dashboard, you get the current pack temperature at a glance, with a color cue for whether the battery is cold, ideal, warm, or hot.

The battery page adds a cold-to-hot gauge with the current average and the spread between your coolest and warmest cell, so you can see how evenly the pack is sitting.

On your charging and drive sessions, temperature is drawn right on the chart as its own line, next to power, speed, and battery. This is where it gets interesting.

Temperature is one of the biggest hidden factors in how your Rivian charges and drives. A cold battery can't take a fast charge at full speed, which is why a DC fast charge often starts slow and ramps up as the pack warms. Near the top of the charge, the pack heats up from all that current and your Rivian eases the speed back to protect it. With the temperature line sitting right on the curve, those moments finally make sense. You can watch the pack warm up, watch the charge rate follow, and understand exactly why your session looked the way it did.

The same goes for drives. See how your battery temperature climbed on a long highway run or a spirited backroad, right alongside your speed and efficiency.

R2 is here, and Rivian Roamer is ready for it.

Rivian Roamer now supports customer-delivered R2 vehicles across the core Roamer Plus experience: software updates, drive sessions, charge sessions, wheel and tire configs, maps, routes, and derived-data pages.

R2 support required deeper compatibility work across the parts of Rivian Roamer that understand vehicle data, sessions, software updates, and location history. The result is that R2 now fits into the same core Roamer Plus experience as R1, with maps, routes, and derived insights working from the data available today.

A few areas still depend on data Rivian has not exposed yet, but the major pieces are in place. If you have an R2, link it to Rivian Roamer and it should start tracking just like your R1.

The new consolidated activity view on Rivian Roamer. Allowing you to view, filter, sort and export all of your history. Now including a map view of your selected time range.

Within a charging session you can now see the sub-charging periods. This is most useful on multi-day sessions where your vehicle tops up over time.

Temperature has a big impact on your Rivian's efficiency. In colder months your vehicle works harder to keep the battery warm, and you'll lose some regenerative braking too. You can now see that impact with the new By Temperature chart on the Efficiency page.

Electricity rate change? Now you can recalculate your previous sessions from your account preferences.

Note: This will not impact any manual or location based overrides.

Every new drive session now records the conditions you drove in: temperature, wind, and precipitation, sampled along the route.

Note: Existing sessions will be enriched over the coming weeks.

What's new:

• Equivalent cycles to date. Every session you've recorded, summed and normalized into full-pack cycles. One cycle equals 100% of usable pack capacity, regardless of how many sessions it took to get there. Five 20% top-ups count as one cycle, same as a single 0-to-100.
• Daily charging graph. Stacked by charge type so you can see your AC vs DC fast-charging mix at a glance, with total kWh added and the equivalent cycle count for each day.

Why the split matters: DC fast charging and AC charging don't stress the cells the same way. Fast charging adds heat and pulls hard on the chemistry. Level 2 at home is gentler. Until now you had a vague sense of your ratio. Now you have the number.
