Announcing our new "CLUBS" section where you can join or create a Rivian club or group! You can use this new feature to conveniently plan and discuss local events, gatherings or other club/group related topics.
So we encourage you to join (or start) special-interest and regional-based Rivian clubs at: https://www.rivianforums.com/forum/group-categories/clubs-groups.1/
Or, it could put it in the 21 to 22% range.Beware of how you calculate degradation. BMS can be off by a few percent. Additionally, my total range shows way less in winter than it does in summer as it naturally accounts for weather impacts. If you’re not checking this with Tesla diagnostics, your numbers could easily swing 5-7% which would put your degradation in the 6-7% normal range.
What he said^^^^^^^^^Battery degradation is something a lot of folks worry about. I have been driving EVs for going on 7 years now. Degradation is not normally an issue these days with active thermal management. There is a normal amount of degradation after the 1st year and after that it tapers off. Even folks that almost exclusively DCFC are not seeing significant increase in degradation (not rivian specific here). Charging over 90% frequently, discharging it below 10% frequently, or charging to 100% and allowing the vehicle to sit with a high state of charge will most certainly accelerate degradation. Set your charge limit to 85% and only charge above that for road trips. Try to avoid running it below 10% if possible.
To measure degradation, unless the vehicle had a mechanism for doing this, you must charge to 100%, fully discharge, and then fully recharge to 100%. This will tell you how much you pulled out of the battery, and then how much you were able to put back into the battery. You also want to know what the official usable capacity of the battery is from new. Using this information you can fairly accurately determine your degradation. Most of that will happen in the first 12 months though. With different brands it is fairly normal to see about 10% degradation over 100k miles. Sometimes a little more or a little less. I suspect a lot of that probably occurs in the first year....at least half of it.
Well, we all know it will degrade, but 15% to 30% degradation is a bit much. In my case with the tesla is around 15 to 16% right now. Hell, I wished it is more than 30% so I can get a warranty replacement.What he said^^^^^^^^^
Too many people worry about this, the battery is going to degrade regardless of what you do to it with the vast majority of degradation occurring in the first year. Charge how you want to the percentage you want, it won't drop below the 30% degradation that they will replace the battery for. Short of cell module or individual cell faults I doubt anyone will ever get close to 30% degradation.
Should be covered under warranty. I have 81k miles on my Tesla Model S over 6 years and only have 10%.yeap. have 85k miles in 3 and a half years and currently at 15% degradation
Yes from what I have seen manufacturer usually guarantee at least 70% capacity over the life of warranty. So 30% I would say is industry standard for HV battery warranty for EVs. Tesla on guarantee theirs for 120,000 miles so Rivian has a decent warranty.I've never seen any manufacturer warranty less than 30% battery capacity
Would 25% be better? I couldn't resist.If you want to take care of battery, don't charge past 80% regularly. To be safe, 75%.
Interesting - give data on the owned vehicle for them to sell and make money so a monthly report can be given to the vehicle ownerRecurrent Auto now has R1T as a choice of an EV. It's an easy way to get a monthly report about your EV's battery capacity and range degradation. I've been using it for my almost 5 yr old Model 3 and plan to use it whenever my R1S is delivered.

At least you're not being obtuse.Sorry to be dense, but how would one know if they have degradation?
My estimated range is always different, depending on recent driving patterns, latest OTA updates, etc.
So, where do I look to see if I have any degradation?
At least you're not being obtuse.
