Electric Vehicles?

[Trell]

Most batteries are still Lithium based, so there is no getting around that, and it is likely the most dangerous aspect of batteries.

I think so too of this types of batteries and this is thermal run-off caused by accidents with the cells damaged. Hard to put out and prone to rear their head long after the accident.

I've been saying this statement ever since the big push for EVs and the claimed reduction of greenhouse gases into our atmosphere. "NOTHING IS FREE IN NATURE WHEN IT COMES TO PRODUCING ENERGY. IT ALL HAS TRADE OFFS" Here's an interesting article that indicates that the manufacturing of batteries produces more EV in the life time of the EV vehicle compared to that of internal combustion engines.

The Environmental Impact of Battery Production for EVs

While the principle of lower emissions behind electric vehicles is commendable, the environmental impact of battery production is still up for debate.

You should not be living in huge sprawling suburbs where each member of the household needs at least one car.

I didn't know I was.

It was a metaphorical “you”.

Ahhh!!! LOL

But the other options are as of yet lacking. So here we are.

Edit: I'm not sure why you brought up NiMH cells as they won't have the current capacity for an EV,

NiMH is mainly hybrids, but I saw an article that said there have been EVs that used it. Likely ones that are not around anymore lol, since NiMH is even worse with hot and cold.

Nickel-metal hydride (NiMH) batteries have long been a popular choice for hybrid cars and have also been utilized in some EVs. One of the primary advantages of NiMH batteries is their robustness and durability. These batteries have a long cycle life, which means they can endure many charge and discharge cycles before their performance begins to decline. Not only that, but NiMH batteries can deliver high levels of power output, enabling quick acceleration and overall strong performance in hybrid cars and EVs.

I can imagine it would be a miserable experience.

wasn't NiMh the de facto replacement in cordless tools and such after NiCad ? None of the memory problems if I remember right ?

The advantage of EV battery production over ICE emissions, is that EV production environmental impacts are at known locations and possibly can be controlled. In contrast tail pipe emissions are spread out over millions and millions of vehicles and thus uncontrollable. Having said that, industries should be forced (regulated) to minimize impact on water and air sources in Li production.

On second thought, perhaps less on Li contamination in the air, for its beneficial effect on manic depression bipolar disorder etc...

What you say about the conservation of energy & mater is certainly true. At the same time, switching to electricity from burning gasoline does offer some real advantages.

I'd be very cautious at believing any article that claims EVs are worse for the environment than internal combustion vehicles. Many of them are the indirect result of propaganda from Big Oil. This has been directly modeled by the propaganda from Big Tobacco, years ago, that swore no link existed between smoking and lung disease.

What brands have you driven or own?

Gas has to be physically distributed, so it has a post processing penalty as well, and that delivery method is one of the dirtiest available. That is before it ever gets used in a vehicle. For an EV, the production of the battery happens once and there are zero emissions after that.

It’s not clear the point you’re trying to make. I don’t think transmission of electricity is as dirty as transmission of gasoline. Could be wrong, but your link seems to be power generation not transmission.

J_garcia stated there were zero emissions once the EV battery was made, just a response to that, nothing more

There are other options for batteries, but they don't have the efficiency , power density and cycle life that Lithium based batteries do. (NiMH for example) That's why hybrids use Lithium Ion batteries almost exclusively, the constant charge/discharge cycles.

It does not get much below the 30s here, but I still noticed my range is lower now in winter. It seems keeping a little heat on in the car is a much bigger penalty than A/C. Oddly, the seat heater seems to be more efficient than the heater, but using both will mean I will have to charge more lol. My commute is ~6 mi one way so it isn't a huge deal, but I noticed it for sure. Ioniqs all come with the battery conditioner, but if I lived in a colder area, I would not have gotten an EV. I still have the STI

It would make sense to heat the batteries while it's charging if the temperature is low. If the battery compartment isn't insulated and temperature-controlled, that shows a lack of forethought.
