re: Assuming most new cars will be EV's by 2030...how to future proof a new home's garage?

Keep in mind that in 15 years you will probably not own a car at all. By that time, driverless cars will be obtainable via ride share, in every shape and size, cheap and fast.

Nah, we won't be there in 15 years.

How many outlets and how many amps would be required?

Trying to future proof is like you know trying to predict the future. I have literally miles of wire in my two houses put there initially to future proof, basically none of it is used.

To answer the question I would make sure the service panel is in the garage. This gives you fairly easy access to all of your power so that you could run any electrical service you need without having to deal with the walls in the living area.

you went in harder than I did. I was hoping to get some bullshite source, but had a feeling it was some regurgitated nonsense talking point.

I thought I kept it civil

EV/Tesla threads can go south very quickly.

It's incorrect info.

Tesla batteries are good for $300-$500k and cost $5k-7k to replace.

After 160k miles, your battery would still be around 90% of its peak performance.

---

Yeah I knew that. I work with Tesla quite a bit on the home energy side. I'm not super familiar with the EVs but the cell tech is the same as the PowerWall and I have a lot of data on degradation, replacement cost, conditioning, cycling etc. on those.

The dipshit Dems will shutdown all power plants due to environmental concerns. So put a solar panel or wind mill on your garage.

News flash the earth doesn’t contain enough materials to make all cars ev. Look it up. Lithium and Cobalt are very limited when it comes to the amount of batteries we are talking about. It’s a pipe dream that will never happen.

Correct. They are already running into issues.

Most chargers ate 50a/240v

There are almost 300 million cars registered in the US, more than there are people.
even if you just assumed half of them were regularly in use, that's an extra 2.6 BILLION Kilowatts being used to charge them. Just for some comparison sake on what 2.6B KW of electricity is, NYC uses about 11 million KW of electricity a day, so you're talking about adding the equivalent of 236 New York City's to our electrical infastructure.
So sure, it's not insurmountable.

The thing that gets lost here is the turnover rate of existing vehicles. People are holding onto vehicles longer than they ever have before. The average vehicle on the road today in the US is 12 years old. 25% of vehicles in the US are >16 years old. A wholesale manufacturing shift to EV’s would only cause that age to increase as people hesitate to make the switch.

New vehicle sales accounted for ~6% of vehicles on the road in 2019, and were expected to fall to 5% in 2020 last time I checked.

That means that if pure EV’s made up 100% of all new vehicle sales right now, it would still take 10+ years for them to make up more than 50% of cars on the road and 15+ years to make up more than 75% of cars on the road.

So extrapolate that out - using that 2030 date, you’re talking about at least 20-25 years from now before even most of the vehicles on the road are EVs. And that’s not accounting for continued improvements in the lifespan of ICE vehicles in the interim or the hesitance of consumers to switch.

Now think about what infrastructure looked like 20-25 years ago. Telecom is a great reference point. How many miles of fiber have we installed since 1996? How many cell towers? Hell, do you think it’ll take 50 years to have nationwide 5G access? Because that’s an even more difficult task.

So no, it’s not insurmountable. Difficult, sure. But I don’t know why anyone would think it can’t be done.
