Why Is home charging slower than Tesla?

[zefram47]

Anyone understand why home charging is so much slower than a Tesla? It’s the same 11.5 kW charging, but R1S gets 25 miles and the model Y gets 44 miles off an hour of charging.
Sigh…..

Because the Rivian only gets 2 mi/kWh and a Tesla gets closer to 4 mi/kWh...the battery is also twice the size in the Rivian. So yes, the Rivian charges slower and recovers less range per unit of time. This isn't rocket science.

If I were to plug an electric scooter in to 11.5 kW it would get 700 mi/hr! Who's laughing now Elon Musk

This makes me wonder: Do some people go to Costco and see a Honda Civic next to a Dodge RAM 2500 in the parking lot and think they get the same fuel economy?

I think most people understand that Honda Civic to Ram 2500 comparison because they are familiar with gas mileage. For now, I don’t know if it is fair to expect everyone to understand EV efficiency as “common sense” since it hasn’t been common for non-enthusiasts to give it much thought until now.

Many people with limited EV experience think that the EV(s) they’re used to got great efficiency so all EVs must get great efficiency. Until the R1T, Lightning, and Hummer they were probably mostly right. Now people who didn’t really give it too much thought are going to start to understand that the old rules still apply even though the fuel is electrons instead of hydrocarbons.

An EV truck may be more efficient than an ICE truck while the same EV truck may also be less efficient than an EV sedan or crossover.

The units are different, so I don't expect anyone to know the math until they own an EV or are otherwise an enthusiast... But the concept of efficiency is the same, so it does surprise me how some people seem to throw out all logic/reason when the term EV enters their mind.

Yea, I had a good lighthearted chuckle in the thread.

When all manufacturers display charging speeds in miles-per-hour, there's always going to be some confusion. Simply because there's no reason why a person would know that's a derived measurement. Gas pumps don't tell you how many gallons you're adding to your car in miles-per-hour, they tell you gallons. So I get the confusion. But it's always a bit of a light chuckle and discussion until the lightbulb goes off in their head.

Right. I think that all this business of electrical theory is something that is new to a lot of people. Kilowatts, kilowatt hours, amperage... It's something that they haven't thought about or had any real experience with. Obviously, the concept of energy efficiency or mileage should be familiar to anybody driving a vehicle. I just think the all this new electrical jargon is confusing or alien for most people. Best thing to do is to help them understand.

If you were to force an electric scooter's battery to accept 11.5 kW, it would go the way of LCDR Billup's warp core.

Not a scooter, but the LiveWire (motorcycle) takes ~13kW charging (DC), iirc.

Exactly! For many of us, we were either technical enough to deal with the concepts right off the bat, or we learned them so long ago that we’ve forgotten what it was like to not understand.

I don‘t want to scare off new forum members by seeming unapproachable, but I also understand why some people are tired of answering the same questions repeatedly. I tend to rely on search a lot but I know others don’t go that route; maybe we need an FAQ section or similar?

*MUCH* bigger / more parallel battery than a Lime scooter.
