Do electric cars emit fine dust when hitting brakes?

Is it really true that electric cars emit fine dust when breaking? I would hope it isn't or they can do something about it, cause fine dust is just as bad as CO2 regarding air pollution. Fine dust is mainly responable for asthma and other breathing conditions, not something to overlook.

Electric cars don't have to use their brakes very much because they use regenerative braking to slow the vehicle most of the time.

you mean regular gas powered cars don't have brakes!

what have i been installing all these years!?

looks like bs to me.

 

[sandorski]

Pretty sure all Auto brakes emit fine dust.

 

[omega3]

An average electric car is responsible for as much (or even more) particulate matter in the air.

This is because it is heavier, due to the heavy batteries. This causes more wear and tear on the brakes, tyres and the street surface, Van Zeebroeck points out.

Quote from the article.. any truth to this?

It may be heavier, but that's more than offset by regenerative breaking, which is contact-less and thus emission-free until something breaks.

I'm calling shens. Cars come in a wide variety of weights, Electric cars don't appear to be any significantly different in weight compared to their Class counterparts. That I could find anyway.

Even if it is true, the amount of dust we would be talking about is ridiculously little. There are cities with millions of cars, Brake Dust has never been an issue.

Brake dust?

What about all that rubber dust from all those tires grinding away on all those roads?

Somebody must be secretly vacuuming it all up every night...

nothing to see here..move along!!

Hybrids are throw-aways.

The total life cycle of a Prius is probably worse than a Humvee ( http://life.gaiam.com/article/hybrid-vs-hummer-which-greener ).

After 7 or so years when the $7.5K+ (and annually climbing) batteries replacement & depreciation expenses of a hybrid are factored to YOUR resale, the car is simply just worth more as "parts".

This is old hat & discussed all the time on car show radio talk programs.

Knock the bull shit off.

All cars produce brake dust as far as I know.

I was going to elaborate on a few other things, but it looks you covered most of that.

 

[tweakmonkey]

Electric cars and hybrids use the brakes way less often than gas cars. Instead they use the motors to put power back into the batteries via regen.

Also Prius batteries don't die after 7 years. They don't cost $7000 to replace.

 

[desy]

Yep they went with 7 and 7000 in that article cause that's what Toyota warrantied for and what at the time replacement's cost , however the batteries didn't die after 7 yrs and the cost when it came time to replace was never that high which blows their calculations out the window.
Certainly there is value in owning a hybrid if you do a ton of city driving

 

[herm0016]

this article is BS. batteries don't cost that much, all cars have brakes. my volt only uses them for emergncy stops or for the last few mph, thus they last a lot longer because of regen braking. ( and generate less dust per mile) there are some battery issues, but the overall life cycle cost of a hybrid/electric is not more than a hummer. the studies assumptions are flawed. Most hummers probably don't go 300k, and most hybrids/electrics have not been around long enough to say they only last 100k. ( ex there are volts over 200k with not battery degradation)

referencing an article that says the study you quote is BS is probably not the best to support your opinion.

just another electric car hit piece with no facts and no logic.

Last I checked people were getting 200-300k out of Prius batteries.

 

[Ferzerp]

batteries don't cost that much

Everything else you said is spot on, but EV batteries of decent range do in fact cost a lot. Hybrid, or city car type EV batteries? Nah, pretty cheap.

Are you legitimately trying to argue that battery pack prices are increasing? Have you been living under a rock?

the prius seems to be the benchmark in this thread.

 

[Ferzerp]

Prius isn't an EV. It's got a dinky little 1.3 kWh, or 4.4 kWh battery for the plug in version. It's a hybrid. You can't really benchmark EVs based on hybrids, especially where batteries are concerned. There are orders of magnitude differences in the batteries.

A Leaf battery is about 18 times more battery than a prius battery (or 5.5x the plug in battery) for example.

edit: a new Volt might be borderline classified in the EV area since it's getting up there in battery size with a 17.1 kWh battery, but traditional hybrid batteries are not in the same realm as EV batteries. Not at all.

Even if it is true, the amount of dust we would be talking about is ridiculously little. There are cities with millions of cars, Brake Dust has never been an issue.

My Camry Hybrid weighs 245lbs more than the 4 cylinder ICE (Internal Combustion Engine) model but hybrids have much smaller batteries than a purely electric car.

A Ford Focus Electric weighs 703lbs more than a Focus Hatchback with ICE. I would imagine that most if not all of the weight difference is the batteries in an electric only car. You lose the weight of the internal combustion engine and transmission but gain electric motors and drivetrain plus the batteries.

duh? we have a gen 1 volt. Stop trying to make sure everyone knows that you are smarter than they are.

 

[Ferzerp]

Well, if you think a Prius battery is a good baseline for actual EV battery metrics....

Wholly agree! Post like these and the insistence of the OP to continue it, instead of learn from it, is how FUD begins.

I have one I'd like to start. Your fart is a greenhouse gas. Therefore outlaw farts. It's for the environment.

Well, that's why some senator wanted to ban bicyclists from the road. Because they breathe out CO2 and fart.

so so so so so wrong.

dead wrong.

a hybrid battery for a 2005 prius cause lets face it, it's 10 years old probably gonna need replaced is exactly.....

1025.79 on rock auto.

so would you throw it away?
