17 MPH - S L O W Charging Rate

[Guards Red Car]

Disappointingly S L O W Charging Speed on My Juicebox 40
17 MPH

My Taycan and Model Y Charge at nearly DOUBLE that speed

Am I missing a setting to allow faster at Home charging?

That’s about right for the power you’re putting into the truck. It’s less efficient than your other cars so it’s going to add less miles per kWh.

That’s why the Rivian charger is 48a

I use 2 juice box's. I hook them both up at 1 time. Much faster

This.
You charge up at a rate - that would be similar to the flow of fuel for ICE. Most people don’t pull up to a gas station and say they are adding however many miles a minute - they say they added 10 gallons.
That 10 gallons would go further Corolla than it would an expedition.

It's not charging at a slower rate.

240V/40A is charging at 9.6kW.

Yep - Rivian's battery is way bigger, so it's going to take longer to fill up. Just like a truck with a 30 gallon gas tank takes twice as long to fill up as the car with a 15 gallon gas tank when using the same gas pump.

It's only 40 amps, so the rate of charge you're getting is correct. Your Taycan wasn't charging at "34 MPH"; it has a smaller battery, 80 kWh?, so obv the 135 kWh will take longer to charge.

As others have mentioned, for the amps available, that is the correct number of miles. With our Rivian charger at 48 Amps we get 21 mi per hour.

Well...

Technically it's both. The Tesla and Porsche have smaller batteries, but they are also more efficient in terms of miles/kWh.

That doesn't change the fact that they are all charging at the same rate with that charger though. It just means that "miles per hour" isn't really the metric OP should be using, because that will obviously be different between a lot of EV's despite charging at the same rate.

True but efficiency has nothing to do w/charge rate. When he is mentioning MPH he's simply stating what miles are being put into his battery per hour, which I think is an acceptable way to think about it. The higher the amps, the more "miles" the charger is able to put into the battery per hour, day, minute, second, etc lol. People won't quit thinking this way for a decade or two.

Charge rate in miles per hour has everything to do with efficiency and nothing to do with battery size. That’s why people get bent out of shape when the same exact charger does 30mph on their Tesla and only 15mph on their Rivian.

It’s an absolutely stupid way to think of the charging process. No one has ever stood at a gas pump and filled up their truck and thought that they’d somehow get the same mpg/range afterwards as the car at the next pump just because they’re at the same gas station.

It may take a generation for peoples mentality to change

Fixed it for you. It never ceases to amaze me that people forget/refuse to recognize the physics of a truck vs a subcompact egg pavement princess. It doesn't matter if it is an ICE or an EV. This truck does things for me that NO other EV out there can even come close to. I also understand that I don't and should never expect it to get the same mi/kWh as a streamlined sedan with 0 offroad capabilities that I have no use for.

The R1T actually has an extremely low drag coefficient, on par with many sedans.
