Standard pack R1T DCFC curve

This doesn't show payload, just GVWR. The other sticker will show payload.

I think this is about 400 more than my quad R1T with 20s. How does it compare to a dual Large with 21s?

This is exactly the same as the DM Large on 21".

Very interesting!

So, if the standard packs were really just large packs that were software limited, it wouldn't only just impact the charging curve, as noted, but it would also feasibly allow you to charge to 100% without concern of impact on the life of the battery, correct? The standard pack is just under 81% of the large pack. BTW, I'm not suggesting this as a daily thing nor would it be necessary...but for those that are concerned about charging to 100% even for the longer trips, this would help alleviate that concern, no?

Absolutely. In fact I'd have no trouble charging to 100% daily if I had a commute.

I think @jjswan33 or another mentioned before, but it's unknown where in the pack the extra 23% sits. If anyone with a Standard or Standard+ is still on 2024.03 update, they could check the Service/RiDE menu. When it's fully charged. Hopefully the extra capacity is a little at the bottom and mostly at the top.

I didn't say it but with the charging curve OP got, showing 100kW input at 85% wouldn't that mean most is at the top of the pack (ie 85% on the standard pack is 70% of the large pack). Maybe my logic is wrong but if they had done the opposite wouldn't the charging curve match the large pack more closely?

It maths to 17.6% on top end, 70% Large is about 94kWh, if that's 85% Standard, total is 111kWh, so 17.6% of the 135kWh is left. Full 100% Standard would be like 83% of the Large, maybe, because they nerf the top 4kWh.

Agree with your math. DM Standard pack is a great buy right now (IMO) at $70k (R1T), $75k (R1S).

I wouldn't be surprised if the software limited large pack is a short term phenomenon.

The SP is advertised as 106kwh. Not sure how that effects your calculations.

Does that include the nerf? 111kW is just the top-end marker, so my guess is the bottom-end is somewhere between 7-12kWh. Even 7kWh is a really good buffer.

Usuable, but not true capacity. We know Large and Max are nerfed 5kWh so if anything, it gives it another buffer of battery protection... Assuming it's a software locked Large. Jury is still out.

I don't think so, I think it's all top end buffer.

From Rivian the usable capacity of the large is 131 kWh and standard 106 kWh.

If you look at the charge curves for the large pack here:
https://www.rivianforums.com/forum/...48-recent-dc-fast-charging-l3-sessions.22635/

The large pack actually hits 100 kw charge rate around 68%

68% of 131 is 89 kWh
85% of 106 is 90 kWh

If there was bottom end buffer on the standard pack, you would expect it to hit 100 kw charge rate at a number less than 85% SOC

As far as my every day use for my standard pack, I am charging to 90% which nets me about 250 miles, if I need the full 270 miles I wouldn't hesitate to charge to 100%
