Battery Report after 3 years / 50K miles (R1S Launch Edition)

[CharonPDX]

google says the EPA range is 315miles, but you don't even break 300. Any idea what's going on here? Do you have the lower efficiency tires installed? I am solidly getting the EPA rating out of my Lightning except on the highway, which I almost never use (drafting at 3 car lengths behind 18 wheelers works really well for extending my range on road trips). Do you just always drive at highway speeds? I'm trying to get a feel for how truthful Rivian's EPA rating is.

Launch Edition (Gen 1 Quad-Large,) when shipped with 20" wheels, was EPA rated ~270 miles. A software update increased the range - TeslaFi is using that increased range as the "base."

Why use this chart and not just check your battery capacity on ABRP?​

Edit: Never mind, found it!

Edit: For those who - like I - didn't know where to find it: First you have to enable Live Data Connection between ABRP and your Rivian account. Then click the "Live Data" link:

(Gen 1 Large pack - only 2% degradation in ~4 years, 32k miles. Not bad!)

Where on ABRP do you find your current battery capacity? The "degradation" field is just a user-entered estimate, not something it pulls from the vehicle.

I'm at 120kwh on my '22 Quad R1Tat 84,000 miles in. So you're not doing too bad at all.

Nearly everything I read seems to indicate that the loss of battery capacity over time is effectively a non-issue, and perhaps as importantly, at least some of any capacity loss has been countered by other improvements in EV technology, Anecdotal evidence, like that of the OP - and my own - seems to provide some confirmation of that.

The general view is that EV battery capacity declines relatively steeply initially and relatively slowly later in the vehicle's life. In a 2023 study from Recurrent they stated that "most EVs experience a five- to 10-percent loss in capacity in their first 40,000 miles, then level off and maintain around 80 to 90 percent of their original capacity to 100,000 miles and beyond."

It may be that those numbers are still accurate, but it appears that EV manufacturers have been able to introduce other improvements that mitigate, and even effectively eliminate, the impact on range from any loss of battery capacity. Here's the graph from a 2025 Recurrent study that seems to indicate that:

Given the above, I'm a bit puzzled by the 97 Range Score that I see on Recurrent for my 2024 R1T with just over 16,000 miles on the clock. More confusingly, Recurrent projects the range for my PDM Large with 20" wheels and AS tires to be 334-335 miles, vs an "Original EPA Range" (the Recurrent EPA figure) of 328 miles. The final range figure on the Recurrent site is the "Est. Range in 3 Years" given as 318 miles. It's not clear if the three years means from new (2027 in that case) or from now, which would be 2029. If the former, that means a loss of 6 or 7 miles over the next year (about a 2% drop) but if the latter, that 2% would be over three years, so under 1% per year.

Either way, the loss of battery capacity over time is not something owners of newer EV's really need to worry much about.
