As a Canadian who's currently driving a 9 year old Mazda 3, I'm waiting for the day it decides to call quits so I can move to an EV (9 isn't that old, so I'm hopeful at least another 2-3 years) That said, I wish there was a site that simply told me now's the right time to buy an EV. With supply chain issues, long waits for a new car, government rebates, and the influx of new inventory/models, it's hard to keep up whe…

Just for the record- it only takes about 21k miles of driving (a year or two for most people) to release as much CO2 as the production of the battery for a long range Tesla Model 3. The standard range Model 3 comes in just under 16k miles. It seems to me like most people expect more. Also, I don't think EV prices have really changed that much. Chip shortages haven't really affected it. High gas prices and inflation a…

Does this assume the electricity is emission free? Because where I live less than 40% of our electricity is from renewables (even those aren't completely 0 carbon impact, as they have to produce panels/wind mills/etc...). The rest is from oil & gas plants.

I understand you are comparing driving an ICE vehicle vs. production of an electric one. But it seems a little misleading to ignore the co2 impact of driving the electric car which is far from 0.

I'm in a slightly different situation --my 2003 Ford Focus Mk1 is still puttering along very nicely with no major issues. I am only doing about 10k miles per year but I need 400 miles autonomy! For me the best next move is to wait for the car to give up the ghost in the road --just hoping I do not become a ghost inside it!

You need 400 miles of range on a charge, even if fast chargers are frequent and available and could give you a useful charge in ~10-15 minutes?

> Also, I don't think EV prices have really changed that much. Chip shortages haven't really affected it. EV prices have shot up along with other new cars. Probably the 2 best known EVs, the Tesla Model S and Model 3 went from $77.4k to $99.5k and from $38.1k to $46.1k in 2021. 28% and 21% increases respectively.

Depends who owns it and what their financial situation is. Anybody who has to stiff someone to scrape up the lump sum to replace a transmission is probably going to replace the transmission rather than roll the dice spending the same or more on a different car that might need something else in short order. Those people also aren't the same people who rack up big bills for random suspension wear parts because they don…

> probably going to replace the transmission With what, though? Not a new part. A transmission from another vehicle that got scrapped. That's the point: these cars don't "last" on their own, they're just the winners in a cannibalism race.

There's a healthy third party parts market for car models with large populations, which includes transmissions.

Older cars can work great but I just lose confidence in taking longer trips. If it’s statistically going to die soon I feel like there’s a large risk of getting stranded somewhere.

>If it’s statistically going to die soon I feel like there’s a large risk of getting stranded somewhere. If you're in North America are you really going to be 'stranded' or just footing the cost of a one-way rental and waiting for the check from the junkyard which will almost certainly cover it?

You could be waiting for hours or overnight on the side of the US interstate (possibly in below freezin/0F temps) for a tow truck that may or may not show up. The salvage check may or may not cover the tow and replacement temporary transportation. A majority of Americans can't come up with $1000 for an emergency, which is somewhat close to the cost of a one way rental at the moment.

This cylindrical form factor might make sense for batteries that have thermal runaway potential, to keep the unit size small so that the whole battery doesn't go into thermal runaway, only one cell. But for LFP or iron based batteries which don't have such issues, the blade design should be cheaper, more maintainable, more space and weight efficient etc. There's no glue so you can actually just switch individual blad…

How would a cylindrical shape isolate thermal runaway to one cell?

So Toyota still uses nimh in its hybrids? Does that make them longer lasting?

They currently use some of both NiMh and Li-ion. Toyota is notoriously conservative when choosing technologies. My guess is they still use a lot of NiMH because they have proven long-term reliability, more forgiving characteristics in harsh use, and they already have a lot of existing tooling to support them. If there any single car that has made the general public comfortable with very expensive batteries in their c…

All those things are true when comparing NiMH to NiCd but definitely not compared to lithium batteries. There's not a single metric for which you can't find a superior suitable lithium chemistry. Except for one: $Cost

Just Toyota doing Toyota things.

Also I would strongly disagree on the Prius comment. A lot of "HV battery fault" cars out there back in the day, refurbing them was a pretty good business for a while. The NiMH pack in the Prius was the basis for so many slack jawed comments "EVs will never work! You're just going to have to replace the battery every 5 years!"

I would guess the more you extend the comparison the worse it gets for combustion cars. Most people get their electricity from natural gas plants delivered through a pipeline, and there is a future prospect to shift this to more renewables. Oil is pumped and delivered to a refinery, then the gas is put on a truck, and delivered to a gas station. All these things require either electricity or gas to run.

"Panasonic Corp (6752.T) said on Monday it will begin mass production of a new lithium-ion battery for Tesla Inc (TSLA.O) before the end of March 2024 at a plant in Japan." Was this detail added by the article writer? Unless something has changed, Tesla cells are produced at the Tesla factories. These 4680 production lines are for Panasonic to sell to customers. Actual press release: https://news.panasonic.com/global…

Model S and X use 18650s manufactured in Japan. Maybe this is some long term plan to transition some unannounced vehicles to 4680?

The model Y in Austin is supposed to use the 4680. Remains a question if the high horsepower cars can work with the bigger cells.
