Every home has a potential charger. Gas “stations” are not needed for most trips in an EV. My EV is fully charged (enough) every morning. It is a huge time saver.
So that argument is bunk.
However, charging an EV takes about 10KW, similar to my 20+ year old air conditioner… and we know AC causes outages during summer heat waves. Imagine every home running a 10KW load every night, all-year long.
I don’t believe our grid is prepared for electric vehicles.
Also, how many of those homes are multi-car? Mom, dad, kid(s) all have to go to work/school at different times and places. Good luck making that work with one vehicle.
Yea, multi-vehicle is a problem, but I think Tesla already has a solution. I just installed their "wall connector" and it has options to chain multiple chargers along one circuit and they will take turns charging the cars connected. So you could easily have 2-3 (wow, six!) of them in a row and they would do their best to charge all your cars overnight.
I wondered how multi-vehicle charging would work.
So does it rotate every so often and all cars are partially charged, or does it charge one fully and then move on to the next?
Then there's the issue of apartment buildings. How do all those get charged? Chargers in every parking slot? That seems unfeasible.
I don't see how we're ready for EVs on a large scale. (I do freely admit though, in a lot of ways, I'm technologically-challenged!😄)
I do not know how the chargers share current. They probably do current limiting based on state of charge for each vehicle. Tesla also allows you to share your calendar with your car, so it's possible they are able to prioritize cars that have earlier departure times than others.
Apartment buildings have electricity, they just need to install the chargers in their parking areas... this is not much different than a house without a charger. People now advertise their home has an EV charger already installed--it is a selling feature! As EV ownership grows, apartment complexes are going to start advertising they have reserved charging spots for EVs as a way of attracting tenants. LOL, craigslist even allows you to search for this option.
That argument doesn't feel debunked to me. It still takes about an hour to charge up in the middle of a road trip, instead of five minutes to fill the tank.
What's wrong with natural gas—we have centuries and centuries of it beneath the earth's crust, waiting to be exploited. Burns nice and clean. Seems like the perfect solution until solar nanotechnology finally takes over and lets every car roof and hood power the vehicle all day long, and into the night with batteries.
Water molecules can also be split using hydrolysis, burning the hydrogen and using oxygen to support the combustion, expelling water vapor as exhaust. Why not slap a condenser on that bad boy, and recycle that exhaust!
That's why H2O and nat gas cars are not happening. Too sensible and cost-effective and energy efficient.
100% accurate.
My grid has hundreds of thousands out of power in a light breeze what seems like multiple times a year now.
Fucking DTE.
"I don't believe..." Your beliefs have no merit in any reasonable discussion.
Belief is the enemy of knowing.
Our grids ARE NOT prepared for electric vehicles. I can say this 100% certainty.
Also, trips have a start and a destination. Are you suggesting Car Chargers will be at all your Destinations as well? If not, that cuts all your distances in half so you can get home to your Charger. Not the case for Gas Stations. You have 100s of options.
Tesla's supercharger network is ubiquitous enough. I worried about destination chargers six years ago. I don't worry about them today.
Not sure about non-Tesla EVs however.
The chargers are powered by Nuclear and Coal plants.
The physical electrical lines to get that power there are only so big and can only handle so much current.
They don't have room on the electrical grid to handle more than 6 Tesla chargers here or there.
They don't have near enough room on the electrical grid for 1 in 5 people to own an operate an electric vehicle. From our estimations and what I've been told by inspectors, only 3-5 homes per block could have a charger. The grids couldn't handle more without serious upgrades. No money for that.
The reality is they will turn Car ownership into a service. The average person will never own an electric car.
I don't know where you are getting your numbers, but the electric grid has way more capacity than that. Tesla's superchargers are consuming 10x more power than my home charger and they have 12-20 of them in a parking lot. That's like 200 level 2 home chargers in one spot.
At my house, the Air Conditioning uses 10KW and the Tesla charger uses 10KW. I can run both at the same time, sure, but normally run AC during day and Tesla at night.
However, the power grid gets overloaded on hot days by everyone using AC... I expect the same will happen when everyone is charging their EV at night. So upgrades are needed, but maybe 20-30% more capacity, not 100% or 200% more.
