I didn’t read all the comments in this thread so I apologize if it’s already been covered but I have a serious question...if everyone is plugging in their EV, can the power grid handle that?

With the Texas power grid 4 minutes away from total blackout last week, imagine if 20% of the people here had EVs plugged in. Forcing EVs is beyond dumb, especially when the infrastructure can't handle the current demand.

I watched a vid on YouTube that said that plugging in your EV is like running 5 "large area" space heaters at once in your home. Now imagine 20%, 40%, or even 50% of people doing that? The power grid would short-circuit. They may have to take an approach similar to what we do here in Vegas when it comes to watering: you water on your scheduled days during the week. Then again...no one follows that anyway (even though you can be fined). We are on the winter schedule right now which means only water on Wednesdays, but there are several houses that do it 3-6 days a week. Must have money to burn.

Just using the Chevy Bolt charging station specs, it shows 2300 watt from a regular outlet (emergency use), 3700 watt (slow charge) and 7400 watt "best fit"

They also list a 11,000 and 22,000 watt options with a do not use.

I would assume they will want most people will use the 3,700 watt version for overnight charging when everyone has to use it, since it is the cheapest rate if you are on a time of day plan, which I would see them forcing everyone to. They might also set it to where your car charges from 12-6 am when most people are sleeping.

If the bolt holds 60 kwh and it gives you 190 mile range. You use 1/3 of that in an average day, You would need to run the 3.7 kwh charger for 5.5 hours. or the 7.4kwh for 2.75 hours.

Assuming you have 2 cars you have to double that draw, quite a bit of power.

For reference, the Mach-E will accept 48 AMPS (need a 60 AMP breaker to stay at 80% max) at 240 V or about 11,500 watts. At that rate, it adds about 30 miles for every hour on the 240V charger. The discharge during "normal" driving is about 3-3.5 miles per KWH.

I have 6 cars and 5 drivers and a 200 amp service into my home. I'd need to add another 200 - 250 amp service just to charge my cars, and it'll still take days on extension chords all over my driveway to do it. So dumb.

Guy around the corner from us has 5 Tesla’s. His driveway has cords all over it and he leaves his garage door open about 6 inches to run them into the garage to plug them in

I would be curious to know what his electric bill is. With 5 of them that’s a shit ton of power. I don’t think I could charge all 6 at once and I gave 320 amp service at my house.

No problem with EV, problem is the mandates. Problem is that EV mileage is calculated assuming energy generation and transmission to your EV is 100%. Problem is a lot of lab claims that can't be scaled. Problem is that when they decrease certain metals, energy density takes a shit. BTW, they have been working on lithium batteries for over 3 decades, hardly training wheel phase.


Yeah not talking about lithium being new, just implementation to EV power sources in general. We're literally in the beginning stages for EV mass production cars.
I drive a phev for savings, I like being able to use electric or gas, my choice. Nothing is 100% whem dealing with transmissions and power loss and mileage calculations. My overall expenses(electric bill increase and pump combined) have decreased significantly compared to when I was gas only(and an economic gas option too). And that's considering gas price are just starting to climb again and likely wont stop until the near $4 a gallon range. Thanks Obama... I mean Joe.
