From my understanding, R1S has consistently been slightly less efficient than R1T, even though they initially thought the opposite would be the case. Using R1S for both is probably safe.

Thanks! Couple parts of the article definitely went over my head, but the gist was ‘at very high and very low temps heat pumps are not as efficient as the AC/PTC combo’. So, I guess the answer to whether the switch to a heat pump in Gen 2 will benefit you is dependent on you’re local climate...

Totally serious, honest question (not being snarky): What are you basing this statement on? An AC is a unidirectional heat pump. Why would a bidirectional heat pump be any less efficient at cooling? Wouldn’t it totally depend on the specific hardware you are comparing? We can say with...

:) My pizza oven only draws 1.5kw so that must be a beefy panini press!

@Rnut Do what you are comfortable with. If it were me, I’d use the 12V connectors behind the hitch cover (link below), jump the truck and hopefully gain access that way. Depending on the response from the vehicle, I’d retry the update with a trickle charger on the 12v...

@COMtnEV This is really great data, thanks for doing that! I wonder why Rivian is reluctant to have the truck condition the battery to optimize L2 charging in cold weather. I really think that is all it’d take but it’s probably not that simple.

Interesting, so do you think it’s just the switch to the heat pump that’s causing the L2 throttling issue at lower temps and high SoC or is there another variable in this equation?

Gave 2024.51.31 another try this afternoon and didn’t see much, if any difference. In the screenshot you can see the classic Gen 2 cold-pack, high-SoC, stair-step L2 throttle. The amperage offset from 2024.51.30 does make a slight difference by bringing up the throttled rate by about 1 Kw. My...

Speaking of A2Z, anyone else getting the extension cable when it comes out? I know, I know, “extension cables bad” but in a pinch I want the flexibility of plugging in anywhere when at a busy supercharger, even if it derates (slows) the charge speed.

Oh no! I hope they didn’t F* up L2 charging for Gen 1 while trying to fix it for Gen 2.

I didn’t take a screen shot this time, but it definitely started throttling at <80%. I’ll do a better job tracking next time and charge above 90% to see where the stair steps are now.

I’ll bet it is pulling some power for heating the pack, there is a 0.5 to 1.5 Kw delta between the consumption reported by the app and the charge rate reported by ABRP. I greatly dislike that my 2025, $90K R1S L2 charges worse than my 2013, $4K Nissan Leaf, but it seems like we’re making some...

L2 charged from 60% to 85% after the 51.31 hot fix OTA. Previously, starting from 20-30F, the pack would warm and hold a steady 46F during L2 charging. Only difference I noticed after the update was the pack temp got up to 48F, which is SOO CLOSE to the Gen 2 50F L2 throttling threshold its...

It’s installing right now. I’ll report back after trying it out.

Don’t know if any of you watch or listen to the Batteries Included livestream on Friday morning. I brought this issue up and am following up as best I can. I think some Rivian folks follow that.

@COMtnEV Sure seems like the Rivian app is reporting total consumption rather than just energy to the battery (Charge rate). It’s strange, the data is coming straight from the vehicle (through the cloud), I don’t know why ABRP and the Rivian display/app are so different on several metrics...

I elevated the low temp L2 charger throttling issue on the ‘Batteries Included’ YouTube livestream today and did get some attention, so here’s hoping someone at Rivian is listening.

Really sorry to hear that @COMtnEV. I’m fortunate my use case makes the throttled charging less of an issue for me, but angry Rivian isn’t addressing or acknowledging it. Was hopeful the latest OTA would help, but it didn’t (even after a hard reset - @Mellowyellow and @OYLman). I’m considering...

Disappointing…and interesting…but mainly disappointing. L2 charged from 73-88% SoC this morning. Outside air temp was mid to upper 20s. Consistent with the report by @Chi_Guy last night, I did not see a change in L2 charging behavior as a result of the 2024.51.30 OTA update. The throttled...

Bummer! I’m giving it a go right now but tempering my expectations. Will update afterwards.
