Let me start by saying I am NOT a fan of EV's. Why hasn't anyone come up with an on board charger for EV's? Have it setup so it could plug into either a 30 amp or 50 amp RV connection.

They basically do have that. It’s a kit with multiple attachments from 15amp 120v to 50amp 240v and everything in between.

Think of it like a Swiss Army knife of attachments with a 15-20ft cord that plugs into the EV.

Tesla's, not sure about others, all have their onboard chargers that convert the AC supply into DC to charge their batteries.
Everyone (Audi, Ford, Tesla etc) I’ve wired seem to follow that design.

I think you’d be screwed without the charger being with the vehicle.

GF got an EV for work 6 months ago, charger went out already, so another is being shipped. Going to charge it is a pain in the ass, all the spots close to us are usually full or shit don't work when you get one, not a fan so far.

AC adapter took a crap? Or the onboard charger?

Do you have a 240v receptacle at home you can use?

If you have a 30 amp outlet in your garage and a charge cord and your vehicle will accept that as a charge per hour most electric vehicles would charge overnight. You can get a charge station and the basic charge station that hardwire charges at 48 Amps. The next charging station that you can buy over-the-counter is an 80 amp charger, which of course would take a 100 amp breaker. Has example my hummer EV I’m getting ready to put a 80 amp charge station in because of the battery gets down to 10%. That would pretty much charge overnight but then again it has the largest battery system of any vehicle made aside from a semi.

So the short answer is if you get a 48 amp charging station that hard wires and you’re gonna be more than fine from any need that you have. But also allows you to charge quicker, of course, and buy the power at night when it’s cheaper per kilowatt hour.

Commercial charge stations can have a DC charge if your vehicle will take that DC if there’s enough kill what hours it puts out like most Teslas do it will charge most electric vehicles in about an hour or a little more.

Crazy as it is something like the hummer if you were to use a 110 V self charger, which it has an adapter for and the battery was down to 10%. It would take three days to charge the vehicle if not more. No one charges on 110 V 20 amp circuit. It just does not pretty quick.

And nearly all the electric vehicle charging cords are not the twist lock 20 or 30 amp type. They’re four prong with a ground.

My Chevy Bolt has an onboard charger. Vehicle came with a charging cord that can be plugged into a standard 110V outlet or a 50 amp (level2) outlet

Good question, the thing on the wall the cord is on lol, it works intermittingly now but the Bluetooth that shows how much electricity was used so she can be paid back stopped working now and she do want to do an itemized bill for it every day. Got new deal for wall, just waiting for electricians to come hook it up. Her work dropped 17k for new panel and conduit work.

He's a ford guy...a bit slow.

30A uses one leg of a double pole breaker...50A pulls from both legs.
Meanwhile this is where my brain goes when I hear a voltage and amperage lol

afaik to get 240 volts you need both "legs".... 30A or 50A or whatever breaker you decide to use

continuous duty should be 80% of the breaker rating for EV charging, or 24 amps from a 30 amp breaker,

40 amps from a 50 amp breaker.

Edit: I forgot about 30 amp 110v RV connections, my bad. And I have one next to my RV pad I wired in 25 years ago!

As an FYI, our Lighting uses the Ford supplied level 2 ,220V charge cord, 4 prong into a dryer outlet. It charges 75% overnight.

I have the 14-30 in my garage for the Tesla. Not the fastest but more than sufficient considering it only goes maybe 20-30 miles a couple days a week. 😁
I tell most people that they’ll be just fine with a 30/240 receptacle. So long as they remember to plug it in lol.

Most of my customers maybe commute 20-30 miles a day. 50 would be big and if they really did 100 I’d be shocked lol.

But I don’t mind getting paid for a 50amp circuit lol

I was lucky enough to be able to choose a gas stove instead of electric to free up a 30 amp breaker.
Does anyone choose an electric stove on purpose? 😁

Chevy Bolt-

On Board Charging Module. 110V @12 or 16 amps (level 1), or 240V @ 32 amps (level 2), or DC fast charging (level3) The Bolt can accept 55kW DC

The Chevy Bolt is one of the worst for DC fast charging at 55kW. Other vehicles can accept up to 350 kW (Tesla) But a Tesla costs about $30K more.

OBCM-

Cord that comes with a Bolt. Level 1 & 2

The original question was why not use a 30 or 50 amp RV outlet.

It takes 220v to charge an EV properly. 110v takes forever.
I originally didn’t catch the RV part.

You can wire a 20, 30 and 50 amp 240 circuit for EVs.


The RDP mantra “more is better” lol. The same way people brag about their 400amp service while drawing 50 amps lol.

It's ok. You're in good company with the reading comprehension issue.

Slow indeed...

Yes. Just bought an induction cook top. It operates at 98% efficiency. Got rid of our gas stove.

Mainly because the price of NG has sky-rocketed. Originally had an older electric stove. Switched to gas. Had that (gas) for 15 years. Loved it but, with a kitchen remodel and the efficiency of the induction, we won't be going back to gas.

Can boil water in less than a minute. 4 Quarts for pasta. Pressure cooker gets up to speed in about 2 minutes. Gas can't even come close to touching that. And, the kitchen stays cool. Most the heat (energy) goes into the pot rather than up the sides and into the kitchen or out the vent.


That thing blows away our old gas cook top.

50 Amp RV receptacles and connectors are 120/240v 4 wire, unlike 30 Amp that are 120V 3 wire.
You can certainly obtain 240V from a 50A RV receptacle.

I’ll type this slow for Mobster…A 50A RV outlet uses both legs and is therefore 220V (or 240V)

We've always been electric, but switched to induction 14 years ago and wouldn't consider anything but.

Saw this today
I’ve got quite a few clients who are all in on EV. Meaning no ICE vehicles. I try to encourage them to look at generators etc but more often than not they see it as a waste of money 🤷🏼‍♂️.

And no one likes a doom and gloomer but a middle of the road generator and 5 gallons of gas can go a long way after an earthquake, fire etc. Especially if you only own electric cars.

Four out of five for me. My water heater is electric.
Well you can usually find some gas for a generator to run that water heater.

My NG tankless is gonna be a bitch to operate if the gas company cuts the fuel. Of course you can convert them to propane but at that point I’ll get the house heater going and we’re taking cold showers.

Whelp, I think if one lives in the Carolinas and or other neighboring states, being prepared during hurricane and tropical storm season might be prudent.

I’ve got 400 gallons of propane buried in the ground. No worries from me regarding heating fuel. If it didn’t get as cold as it does here it would probably last a year.

So in true RDP, money is no object, fashion and a clean sheet design, what would be the ideal home charging setup for an EV?

Three phase 220V?

12,000 + watts of solar is ideal with 15,000 watts of backup lithium batteries.

Electricity rates are going nowhere but up everybody needs to analyze this.

A 60 amp circuit feeding a level two EV charger in the garage regardless of the power source.

60 amp circuit would be 408v?

60amp 240 EV service with a 15kW battery back up system. And if we’re really getting after it, couple that with a 20kW solar system.

And of course we need the 10-20kW diesel generator with a 300 gallon diesel tank. That of course you use to fill your 3/4-1 ton truck with.

Diesel is delivered once a month.

Assuming you have 3 stand up freezers full of beef, elk and sushi grade tuna you should be able to survive a weekend without power.

Thanks, I’ll add that to the book I’m writing called “I wish I was a Baller…”

I have single phase, 240 VAC.

60 Amp breaker in the garage sub panel just to charge the EV. Sub panel is fed by a 100 Amp breaker in the main panel.

Its darn near impossible to get 3 phase to residential housing.

I ran 60 amp to garage and RV parking on my project house. Figured if EVs do take over can charge 2. Can also run my welder in both locations.

At the house I moved from it had 30 amp. My Ex Tesla if it was low on charge would not fully charge in off peak hours. But her electric bill was so high She wouldn't charge during peak.
