Yeah, that’s similar to the FB post from about a year ago which showed a real invoice from a Florida car dealership that quoted a $30k price to replace a battery for a Chevy Volt. What wasn’t revealed is that it was a 2012 model car, and the battery had been discontinued by Chevrolet, so it was a 3rd-party supplier.
Most newer EV batteries will probably outlast the vehicle in which they’re installed.
Well, yeah, That goal can & likely will change. But since they added in plug-in, that issue is not as bad as people think.
Of course they are. First of all, like I said, everyone I know that has an electric or plug in has rooftop solar. And we are not gonna run out of gasoline in the foreseeable future. We want to switch to electric to reduce emissions and CO2. True, driving an electric car that is 100% charged with natural gas does little to help CO2, but a lot to reduce smog.
Next natural gas is taking over coal, and that’s not so bad.
“a man”. Pretty much worthless. So, he is a nut that wanted publicity. I dont see how that means anything.
People commonly buy new cars every so often, and tesla batteries last between 300000 and 500000 miles. Few people drive their car more than 200K before getting a new one.
Yeah, I just got rid of a 20 yo car with a bad transmission. Does that prove transmissions are too expensive? Nope. It just shows that an older car reaches a point where a repair costs more than the car is worth. All cars.
Yep.
How much power does it take to charge an EV? How much do solar cells on the roof produce? During the daylight hours, my EV will be with me at work. I have to add the cost of solar cells to the cost of operating an EV.
I’m not if California, but my worry about having an EV is paying for it. I bought a Ford Ranger three years ago for $3,000. I expect it will be a while before used EVs are available, and the batteries in a used EV are probably not going to be in good shape. I have no problem with owning an EV, but I doubt I’ll find one for $3000.
Upon Googling, an EV charges with 7,000W. A roof array of solar cells produces 400W/hour
I would say that natural gas would indirectly lower CO2 emissions because you only have to transport it once.
There already are plenty of used electric cars available. This article from Jalopnik describes some.
$35,000 vs. $3000.
You didn’t think they were available at any price. And several years ago, Jalopnik ran an article in which someone described the used $2,000 Nissan Leaf they purchased.
An electric car, when charging at home, will draw between 1000W and 10000W. The range added to the car per hour of charge will vary accordingly. 1000W for a duration of an hour = 1000 Wh = 1 kWh. An EV battery’s capacity is typically between 60 and 120 kWh, but of course it’s not typically depleted when plugged in.
Watts per hour is not a unit. A roof solar installation will have a maximum power (number of watts) it can produce with optimal illumination and orientation; but the real output will vary widely depending on time of day, cloud cover and orientation relative to the Sun.
That is certainly doable, but the range is disappointing. During my previous marriage, I was driving between Little Rock and Memphis often to pick up my step daughter at the Memphis airport.
A few random points:
kWhrs are certainly units. I understand that output would vary, but how is the power produced by a solar cell array expressed?
You keep changing the parameters. How soon before you’re looking for a $10,000 electric vehicle capable of a thousand miles of range and able to transport a semi-trailer of hay?
EV charging is far easier than filling with gas. If you get a 30% charge from solar during the day, great! No extra stop or time taken out of the day to do it. Finish filling at night when power is cheap, or if 30% is enough of a gain, then don’t bother filling the rest of the way later.
ETA: in many cases it’s more cost effective to put the solar into the grid during the day when they’re is a better return on selling it, and charge the EV at night when electricity is cheap to buy.
EVs can get more CO2 friendly over time. If it is charged from coal now, it is still better than a gas car, but in the future it may be charged from solar or wind, and with no changes to the car it becomes much better than a gas car.
Right now, today, power companies can control when EVs charge at night, so they can stagger them so they don’t all need to charge at the same exact time. Instead of needing to fill every car starting at 10pm (or whenever power gets cheap), start some at 10, others at 12, etc. so at any given time the number of cars charging is predictable and the load I spread out.
Have we taken into account that at the same time we decided that gasoline cars are so evil that they can’t be allowed, we’re doing the same thing for gas stoves, and natural gas appliances in general.
Like will the grid handle it if everyone gets home at 6, plugs in their new electric car, puts a load of clothes in their new electric dryer after washing them and taking a shower with water from their new electric water heater, then starts to cook dinner over their new electric range.
Then at night when everyone’s car is still charging, it turns out it’s a cold night so everyone’s electric heat pump is also working full blast to keep their house nice and toasty warm.
Really? What year is it?
2008, with an ugly scratch on the passenger side.
Which is part of why state mandates like this are important. With this mandate, it’ll become very difficult for landlords not to offer charging options. They want to be able to rent their apartments, and if they don’t have charging ports, who’s going to rent from them? Chicken-and-egg problems like this are a great place for governments to step in.
Right, the proper technology, right now, for general household and family use is a plug-in hybrid. There’s no excuse any more for gas-only vehicles.
Yes, we have stupid people in this country, too.
A fair bit, actually. Out of all fossil fuels, methane releases the least CO2 per energy, and even with a coal power plant, the end-to-end efficiency is still considerably higher than a gasoline engine.
Those numbers don’t make sense. As in, they’re not even wrong. That’s like saying that you’re six gallons tall.
Some of the gas stations where I live (Iowa) have EV plug-ins. Not the majority, but they are there. They are off to the side, so there’s no confusion about what they really are.
Like I have said elsewhere in this thread, they are useful FOR SOME PEOPLE. They aren’t right for everybody, at least not yet.
While we’re on the topic of YouTube channels, I sometimes watch a railcam, mainly to watch the Amtraks arrive, but one day, a train composed mainly of coal cars went by (those are open at the top) and someone said, “Look! Fuel for electric vehicles!” Yeah, he kicked up a bit of a poo storm.
kW is a unit, it’s instantaneous power. An old-fashioned incandescent light bulb consumes 60 W, or 0.06 kW.
kWh is a unit, it’s 1 kW X 1 hour. If you turn on that 60-watt light bulb for 20 minutes, you’ve consumed 20 Wh or 0.02 kWh. That’s visible on the house’s power meter… and power bill.
But kW/h (kilowatts per hour) is not a unit, or at least it doesn’t represent any useful measurement. But you’ll find websites of solar panel companies that will use that as a unit; usually it means you should be wary of their other claims.
As for solar panel units: the peak would be measured in W, typically below 2000W at solar noon for a well-oriented house. But often you’ll find estimates labeled in kWh per year, which is more convenient when figuring out if the installation is worth it money-wise.
Thanks, Heracles.
