Best Charger Available?

[SANZC02]

I understand that the electrical codes would prevent 480-volt service to residential, but I see the Terra unit can support 22.5 kW if supplied with a single-phase 240-volt, 100-amp input. Level 2 chargers range from 3 to 18 kW, and commercial level 3 chargers 50 to 400 kW, according to this link https://electricvehiclegeek.com/level-2-ev-charging/

So, home DC charging seems like it would not add any value. Thoughts?

The advantage to DCFC charging is it bypasses the on board charger. For the Rivian the max the on board charger will do is 48 amps which is 11.5 kWh. If you can get a level 3 charger running at 22.5 kWh you could almost double your charging rate. That could take a Rivian from charging around 24 mph to 45 mph.

Not worth the expense to me personally as there are several DCFC chargers around my house if I ever needed a quick boost for an unplanned trip. For people that do not have that as an option and occasionally need a quick boost it is good to see options are out there.

Hello,

I purchased my R1S about a month ago and had my electrician put in the Tesla universal wall charger on a 60a circuit but it only outputs 48a. I’m having my house electricity redone and brining in a 400a main breaker so I can improve the ev charging and update a few other things. With that much extra power what is the best wall charger you can buy so I can decrease the amount of time to charge?

You’ve got the best setup with the best charger. 60amp breaker with the Tesla Universal Charger. The car can’t take any more power than that so you can’t decrease the time to charge any more than this setup. For all the things Tesla does wrong, their Wall Connector is Outstanding with excellent support.

I am definitely on the "If you need a fast charger at home, think really carefully if an EV is going to be the right choice for you" train

Don't want to tell anyone what to do, but I think advising to really think about your options is good guidance here

It only takes about 12 hours to get the R1 large pack from 0% to 100%. What else could you possibly need???

Otherwise, all EVSEs in a give power rating are exactly the same as far as charging. Some may have different apps and things like that, but they charge exactly the same way. Buy a cheap one.

Don’t you sleep for a few hours a night? Is that not enough time to charge to 80% each day? You don’t get an award for charging faster!

I also have the hardwired Tesla Universal Wall Charger, 60A and 48A to the car. It works great and I'm able to charge friends' Teslas and hopefully future proof a little with the NACS as well. If I'm leaving for a weekend road trip, I'll charge to 70% Thursday night and then Friday night charge to 100% and leave Saturday morning with 100%. It just takes 15 seconds of planning and effort.

Definitely some missing context here is the number of miles you drive on average a day, and how long your vehicle remains at home when not driving. I think for most normal circumstances, a Level 2 charger is going to be more than sufficient for people as their home charging solution.

Definitely. Hell, I use an (industrial grade) 20-amp wall socket and a mobile charger for charging my Teslas, and that’s plenty. Note that that wouldn’t work for a thirsty R1 unless you only drive 20 miles a day and never experience a winter. I tried.

You really shouldn’t fast charge your battery that often. Definitely not every time you charge. You’ll see battery degradation pretty quickly and will be annoyed with the range drop.
