Newbie Duh Charging Question

[oskeei]

Thank you. When you say precondition, does that mean to wake up the car for 20 minutes prior to driving?

The Rivian app has a feature to allow you to set your departure time. Keep you S plugged in and set the departure time in your app. The S will have the battery and vehicle warmed up for you before you leave and will draw the power from the charger vice your battery. Maybe waking up the S will accomplish sometime similar, but it'll eat into your battery.

Have not used the feature myself so speaking from what I saw in the app.

Found it thanks!!

Great - I was at a VRBO over Thanksgiving and had the wrong (since purchased) dryer adapter so I had to plug into a regular outlet in the garage. It gave me about 2 miles per hour plugged in, but since it sat there for three days, it was plenty to get me to the charger I knew I had to hit on the way home anyway.

For those who have _not_ already spent the money to put together your "away" kit, do yourself a HUGE favor and buy the Tesla mobile cord with the NEMA kit.

• You will never have the issue above of not having the right adaptor.
• Each adapter actually tells the EVSE how much to pull, so you don't have to guess around with vehicle settings (get it wrong, bad juju).
• The EVSE will actually test the outlet when it is plugged in, and back the draw down if the wiring is hinky. Your Rivian mobile cord will NOT do that.
• Because the Tesla unit does the above, you can still get a safe charge even if the wiring is not perfect, although usually at slower speeds. The Rivian mobile EVSE was so picky about the shitty outlets in Mexico that I just gave it away. I was honest with the guy I gave it to: "this thing is crap".

Thx so much!. Are you referring to this specifically?

Yes. Then get the NEMA kit for it if you want to be able to plug into any NEMA outlet:

Just click the fan icon in your app 20 minutes before departure. You can schedule it too if you know what time your leaving.

Thanks R.I.P. A couple of follow-up questions for you, and anyone else that can help.

1) Because I plan to use RV campsites to charge while road-tripping, I just bought the ShockFlo G1 Level 2 Portable Charger because it supports currents as high as 40 amps. (The Tesla Mobile Connector's max current seems to be 32 amps from what I'm seeing.) Do you know anything about this unit, and how it compares to the Tesla Mobile Connector, especially some of the safety aspects you mention above? Since the Shockflo uses a NEMA 14-50 plug, I would have to buy separate adapters such as the 14-30 to 14-50 one mentioned above to handle various plug situations.

If I did end up buying the Tesla unit...

2) Unless I'm missing something, the use of the Tesla mobile cord will require the use of Tesla to J1772 adapter, right? Do you have a recommended one?

3) The Tesla Mobile Connector comes with a NEMA 5-15 adapter and a NEMA 14-50 adapter. Tesla also offers various separate adapters at $45 each on this page. Based on @KBabione 's recommendation (and my own home situation), I would get a 10-30 and 14-30 adapter. Do you (or anyone else recommend any others?) (Hopefully not too many; this is starting to add up $$$.)

I just took delivery of my R1S last week, so I'm trying to get it properly outfitted!

The "shock flo" is a sub-grade chinese unit that can easily pull too much from the worn RV outlets you will come across, has none of the safety or line testing features of the Tesla unit, and may or may not work when you really need it. RV outlets get a lot of use; & I don't remember ever seeing one in "excellent condition". Tryin to pull north of 40 out of one for 10 + hours is a recipe for disaster.

It will not adjust to the outlet.

Yes, even without a NACS mobil cord you need a NACS to J1772 adapter to charge from the ubiquitous NACS EVSEs at hotels & businesses all over the county..

Do not buy the Tesla NEMA adaptors individually. Buy the complete kit. It comes in it's own bag, and ensures you have what you need for any given stop.

Thanks for the heads up about the Shock-Flo.

I went back to Tesla site, and see the full NEMA adapter bundle here. Thanks.

I'm not sure how buying a Tesla product helps on a ccs car but it's all adapters anyway. For 110v charging extension you will want at least a #12 wire which is 20A (25 ampacity). Uncoil to avoid inductive heating. It's hard to know what you'll encounter for plugs.

So far I've only bought a tt30ev adapter because I frequent RV parks and some don't have a 14-50.

To specifically answer your question, " buying a Tesla product" Will get you up to double the power out of that outlet when compared to the setup you have pictured. The Tesla unit will not only identify that you are using a TT30, and draw up to 24 amps out of it, but it will continually test it to make sure the wiring and outlet are healthy enough to maintain that.

The setup you have pictured is simply pulling from the TT30 as if it were a 15 amp outlet.

You are mistaken. The tt30 is going into the 14-50 on the rivian mobile charger which can draw up to 32A. The cost is for this adapter is almost nothing compared to buying a Tesla adapter that needs adapters on both ends to work on a CCS car. The bundle doesn't even come with a tt30 so after buying the bundle I'd still need to buy the one. The automatic amperage setting on the Tesla is nice but I can set it in the Rivian as well.

Ah, you are using half of the 220 on the EVSE.

Yikes.

It's no different than the 5-15 110v adapter that comes with the rivian except it allows more than 12A.

 

[greg_R1S_on_Order]

Thanks Ken. I appreciate your help! I have downloaded all the apps and set up accounts where necessary. It seems like the adapters for 120 and 240 volts came with my R1S. I am buying extension chords for both for the regular 120v outlet and the 50amp dryer outlet. I think I am covered when at a cabin up in mountains for a week with those 2 (slow charge but that's okay I don't do a lot of driving when in mountains or at a outer banks house.

Great info on the electrify America and EVgo. I am learning so much, and this forum is fantastic support. Thanks again!

If you're in the NC mountains note that there are RAN (Rivian Adventure Network) fast chargers in Blowing Rock and Whittier...
