How to charge faster at home?

[Merrill]

I have a 220 plug in my garage I use for charging my Rivian but it seems to take around 12 hours to go from 120 miles to 280. Is there a way to charge faster.

260 miles / 12 hours = 22 mi/hr
At 2 mi/kWh, this is about 11kW which is about maximum for a 60 amp 240V circuit.

Bad Math (note to self: never do math online), but logic was correct:
160 miles / 12 hours = 13 mi/hr
At 2 mi/kWh, this is about 6.5kW

Yes...most people do better with their home charger. Maximum expectation:
60 amp 240V circuit = 11.5KW or about 77% faster than what you're currently experiencing.

Edit: Bad math

Truck will accept up to 48A on Level 2, and it should report what current rate is being accepted by the truck on the dash. If your EVSE is the plug type, it's likely either 32A or 40A so you could get a little more speed out of a hard wired unit.

It is showing 7kW on my 220 plug which is hard wired to a separate 50amp circuit breaker in my main electrical panel.

What EVSE are you using? That sounds like 32a, if so, you're leaving ~2-3kWh on the table with your existing circuit.

For reference, our Grizzl-E will do up to 40a (on a 50a circuit) which gives the Tesla 9.6kWh (FWIW, ours is on an outlet vs. hard-wired, I like the ability to easily swap it out).

I agree with other comments. If you want to charge a little faster, you need a 60 amp breaker hardwired directly to a 48 Amp EVSE, no plug. Your "220 plug which is hard wired to a separate 50amp circuit breaker" does not meet the definition/requirements when talking about "hardwired" EVSE. 60 amp rated wire (typically installers use #6 THHN) must go direct from the EVSE terminals to the breaker.

I don’t have an EVSE, the plug is hard wired directly to my main service panel.

That’s an easy question.

Just buy this.

The Charing unit need to be hard wired to the circuit breaker directly to get 48Amps not plugged into a socket that is wired directly. I recently switched mine from plugged to hard wired and now get better charging.

The Count looked into it but his homeowners insurance balked at having such a "commercial" appliance covered by his liability/umbrella. SAD!

I think the nice thing about this is the 4 interest free payments of $17,999.75. Kinda makes it feasible

don't forget it qualifies for free shipping too

Another possible option soon to be released... Residential 20kW DC Fast Charger. This product is 'Coming Soon' on Indiegogo.

The thing you are plugging into the plug is the EVSE.

Are you using the Rivian portable charger into that plug? If so, then you're only getting 32A...about the 7kW.

I have and EVSE charger plugged into a 50A circuit and pull 9-10amps pretty regularly. That's about 18-19mph. You can go up to a 60A circuit, but the additional is only going to get you to around 11amps or 23-25mph.

Last week before a road trip, it took about 10 hours to of from mid 30% to 100%
