How to charge faster at home?

[MaskedRacerX]

Sorry for the confusion, I appreciate everyone’s help.

Yeah, for FWIW, if you've got a good functional charger running at 32a, going to 40a with another product isn't a huge jump - and it's very dependent on your use case / consumption day-to-day.

Like for example, if I drove 60 miles round trip (like for a daily commute) with our Tesla, that's ~19kWh consumption.

At 32a which is 7.7kWh, so roughly 2 hours 28 minutes to replenish.

At 40a which is 9.6kWh that's right at 2 hours.

Overnight? Almost meaningless

I agree, it’s not a problem I was just seeing if there was an easy way to bump it up a littl.

don't forget it qualifies for free shipping too

Forgeting Federal monies although that may require allowing your neighbors to charge too

Sure, it can help on occasion and if it's an easy process, like just buying another charger, start shopping

Heck, it's actually nice having an extra charger anyway, for a backup, to keep in the vehicle for using it on the road. I take the Tesla mobile down to the BIL's and use his N14-30 outlet (on his dryer) for charging, super handy.

Search for Emporia charger on Amazon. It will bump up to 40 amp for you which is about 9 kwh. $400. If you want faster to 48 amp, tell your electrician to change to 60amp panel and wire directly to the Emporia charger

Just want to educate OP to use 'NEMA 14-50', not 15-40 (incorrect)

You can buy the charger in the rivian shop and put a plug end on it to get 9 KW. $800 + plug ($30) plus one hour or someone's time if you can't install a dryer style plug yourself.

You can pay an electrician to hardwire it to a 60 amp breaker and get 11 KW. ($800 + electrician costs).

Both cases free your mobile cord to stay in the car.

If the current rate is acceptable to you, permanently charging with the mobile cord is fine.

I guess you use the Tesla mobile charger to charge those listed in your vehicles.

That’s an easy question.

Just buy this.

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.

Technically, you could boost that voltage up to 250 or so and squeeze out another half a kWh or so. But that's beyond the ability of the average owner. Agreed that OP should look at amperage first.... And read the manual about charging.

I was charging at 8kWh with the Rivian provided charging cable connected to a 50 amp power panel I have for my Travel Trailer. Them, I instated Tesla J-1772 charger on a 60Amp dedicated circuit. This EVSE now provides 11.5 kWh. It is critical to me to charge faster because my electric company assigned me an EV rate of Super low Off-Peak from 10PM-5am at 0.411 cent per kWh. That's the time Mostro is scheduled to charge. Tesla T-1772 was $550. Installation cost $975.

Wow. Nice BIL. He doesn’t mind “gassing“ you up?

Wouldn’t a slower charge be healthier for the battery in the long run?

 

[Greg Chick]

The length of the line supply from the main panel to the charging unit is a factor that causes a power drop. The quality of the connection of the wires in the panel, the charger both make a difference. The trained electrical contractors or journeymen, use a method of causing a full contact at the connectors. My Rivian charger delivers 21 MPH to the R1T noting 42 Amp capacity, consistently according to my dashboard. This is on a 50 Amp. Breaker and short distance in line wires using 4 AWG. BTW, this is without tripping the breaker in 100 degree weather daytime charging for over 2 hrs.

At L2 rates it's actually better to charge faster.
