I can state with a high degree of statistical confidence that my new Gen 2 Max Pack R1T charges as fast or faster than my Gen 1 Large Pack. I've used primarily Electrify America on my road trips (very successfully). The charging session data is shown below. ** There are 39 charging sessions...

What is the Minnesota location? Clicking on the pin says “Maple Grove” but that is not where it is located on the map. Maple Grove would make sense as there is an REI there.

I've canceled my monthly Tesla charging membership. I will use Superchargers but only as a last resort. In the last year or so there have been huge additions to the charging world by multiple providers (Ionna, Pilot Flying J/Circle K/KwikTrip/Rivian/MB/BP Pulse is coming on strong/etc)...

This has been my observations of range/efficiency vs temperature. 35% loss at 0deg F. This is on a 3 hr trip. Short trips can have much worse efficiency.

It does seem to take a long time most of the time. However, Ionna is constructing and opening large, impressive stations in a couple months. They are showing it can be done quickly.

That is a very good suggestion and one I considered. However, this application is at my rural cabin and I have a one stall garage. I want to mount a EVSE (a Grizzl-e!!) on the outside of the garage for my second vehicle. I'm tired of snaking the cord through under the partially opened entry...

Thanks for the inputs. For my application I have the heater in a work room and the EVSE would be 20 feet or so away in another room so I think the big Siemens safety switch is the way to go.

yep. That looks better! Thanks.

I have a 40 amp charger on one 50 amp circuit in my garage. I also have a garage space heater on a different 50 amp circuit breaker. I want to add a 2nd charger to the garage. I was wondering if a toggle switch could be installed on the circuit with the space heater to select between...

What was the battery temperature? Did you was preconditioning occurring while you were driving to the chargers?

I don’t agree. I drove my Gen 2 this week at -13 deg F and I got full heat in less than 1 minute. I set the cabin temp at 66 deg and was very comfortable. If a heat pump had to extract heat from cold air they do struggle. But the Rivian gets excess heat from the warm motors so they work...

Here is a post I remember from a couple years ago on the Mach-e forum. A Mach-e left outside in Fairbanks at -35F. All was fine except the expected range loss and weak cabin heating https://www.macheforum.com/site/threads/35f-37c-real-world-mach-e-range-test-what-could-go-wrong.11669/ Text...

How are you determining what your battery capacity is? That is not a simple thing to measure.

I count 4 data points.... Now 5, I just added one from a trip 2 days ago. The data is pretty consistent across all modes/Gen1 and 2. Extrapolate to colder weather if you need to. Regarding the convergence of the All Purpose and Conserve at colder temperatures. I don't know the answer but...

This is the data I've collected over the last 2.5 years. This is traveling the same route over and over. 40% of drive at 70mph freeway and 60% at 60mph state highways with many small town slowdowns.

My Gen2 R1T. 48 hrs unplugged at 70% SOC in a cold MN garage. 48 hrs later it was 69%. Consumption meter showed 0 kWh used. I plugged it in to get back to 70%. Took 8 minutes and truck UI said 1.3 kWh of power was delivered to the battery. So a loss of about 0.6 kWh per day.

I've had both a Gen 1 and Gen 2 R1T. In my experience and testing they charge nearly the same. I wrote an extensive post on it here; https://www.rivianforums.com/forum/threads/r1t-gen-1-quad-large-vs-gen-2-dual-max-pack-efficiency-and-charging-analysis.37135/ I have not tried charging after...

I also think the battery temps are different this winter. I have yet to notice any change in efficiency but need a little more drive time in cold weather to say for sure.

Hmm…. By my math it is $6.90 per gallon equivalent if the ICE vehicle gets 20 mpg (a vehicle in same class as a Rivian and the Rivian gets 2mile/kwh). Still a lot but not close to $23.

I think he is speculating that part of the upcoming J3400 standard will be that other automakers will enable the 277 AC charging with makes it easier for business/apartment complexes to lower the cost of L2 charging installations.
