I heard someone said that, at the end EV will cost you almost the same as gasoline vehicle, if you have to change the expensive battery every so often. Can someone please give me more info on this? Thank you so much.
I believe this is the total cost of ownership calculation.

This is great. but maybe factor in if you have solar. I can generate my own free electricity but I can’t generate my own gas no matter how many visits to Taco Bell.
Even without solar there are lots of places to charge for free (slowly, but it adds up)
Also gas is way more expensive than that here in CA. And gas prices fluctuate like crazy. Electric prices generally don’t.
My electric company gives me monthly credits because I let them control when my car charges based on demand. I just set it up to “be ready by 7am”. Combined with solar it makes my charging cost negative.
OMG, my 0.99 L gasoline car is still a lot cheaper than any of the electric options I could come up with. I guess the year of the electric car isn’t here yet. Then again, I couldn’t even charge the car at home, so there’s no hurry to switch any time soon.
The availability on street charging for those without driveway is really the only thing holding back mass adoption, IMHO.
I’ve heard that the electrical grid wouldn’t be able to handle it if every car was electric. Not just the energy production, but also the wires buried under the streets.
For people who don’t have access to charges at home, like apartment dwellers. Owning an electric vehicle becomes a lot less convenient, cuz you’re not getting the efficiency from solar panels, or late night charging. You’re at the whim of the price of fast chargers.
But the math is constantly changing, it’s good that it’s a viable option for a lot of people. I look forward to a more sustainable future.
To put on my engineers hat for a minute, I honestly would prefer that we switch over to hydrogen fuel cars rather than electric battery powered cars. Batteries are more e-waste, not recyclable, unlike hydrogen.
But that’s a pie in the sky dream
Car batteries last more than 10 years in cars, have a second life as static storage for likely much more than 10 years, and we currently have the ability to recycle over 95% of battery materials into new batteries.
Hydrogen used in fuel cells has a round trip efficiency of around 30% (compared to 90%+ for batteries). If the hydrogen was generated from solar power, we would need 3 times as many solar panels to drive hydrogen cars vs battery cars.
Most (98%+) of all hydrogen is currently made using fossil fuels. The most common method is methane steam reformation. The methane (natural gas) is combined with high pressure, high temperature steam. The methane reacts with the steam to produce hydrogen and carbon dioxide.
The carbon dioxide is usually vented to the atmosphere (some places capture the CO2, and use it to pump oil out of the ground where the CO2 is also released into the atmosphere).
The hydrogen also contains less energy than the methane that was used to make it.
I see great potential in hydrogen, because we could produce lots of it by dumping excess solar and wind energy into electrolysis. That would mean that instead of burning coal, oil and gas in peaker plants, we could use hydrogen for grid balancing. Assuming we had that sort of hydrogen infrastructure for the grid, we could obviously put some of the hydrogen for road vehicle use as well.
In the short term, cost is going to be an issue, but that can be overcome through economies of scale. However, safety is a bit tricky due to the explosive nature of hydrogen. I’ve heard of various creative solutions but they always come with serious drawbacks. So far, storing hydrogen in a pressurized tank seems to be the least awful option out there. On the other hand, electric cars will happily ignite from time to time, so I guess we’ve already accepted a certain level of danger when it comes to vehicles.
