It's definitely preferable to grinding brakes to slow the vehicle both because of the reduced wear/pollution and extended range gained from the small bit of charging that occurs.
You don't need to have the one pedal driving enabled to reap the benefits. In all EVs and PHEVs you brake with the electric motors first even when using the actual pedal - normal brakes are engaged only past a certain threshold.
Also to give a personal anecdote, in my Volvo XC60 PHEV, I've just had the inspection done and after 24k miles the brake pads are 5% worn. That's insane for a 2.2 tonne SUV with 400bhp. If it wasn't a PHEV I can guarantee that the pads would be nearly worn by now.
Sure. My last car was a Mercedes AMG that needed new pads every 8-10k miles, so I might be a bit biased. But TBF my car before that was a Land Rover Discovery 3 and that was eating pads like crazy despite not driving it aggressively at all - I attributed it to the weight of the vehicle.
You are very out of date, on a modern car the rear brakes will go first. With traction control they move all the braking to the back, if possible, so steering works better. Of course if you brake hard there is no choice but let the front brakes take over, see my comment about bad driving.
This is not true. At least for Teslas, the brake pedal only controls the friction brakes (they are hydraulically coupled). Same with a Chevy bolt. Unsure on other EVs
Yes, Tesla is an outlier in the EV business. They only have one-pedal driving with regen or fully friction braking with the brake pedal. That is not true of the Chevy Bolt.
Almost every other EV (and hybrid) on the market does blended regen with the brake pedal. Regen is applied when you first press on the brake pedal. As long as the pressure is mild to moderate, regen is used. If you press hard (as in emergency braking) the friction brakes are engaged. When you get below about 10mph the friction brakes are also applied as regen is minimal at that speed. The result is that these cars will do regen whether you are using one pedal driving or not and their brakes will wear much less often.
I’m not sure why Tesla doesn’t do blended regen. Early one the manufacturers didn’t have the algorithms tuned and you could feel the transitions but that has not been the case for several year. It seems that Tesla just never bothered. They seem to expect you to only use one-pedal driving and some people do.
One think to watch for if you only use one-pedal driving, your friction brake pads can get rusty from disuse. Then when you do press on the brake pedal, the brakes may grab or may not decelerate as quickly as expected. Some people find that their brake pads are actually frozen from rust and don’t work at all. It is a good idea to once in a while use those friction brakes to scrub off the surface rust.
Well regenerative braking is limited and even more limited when cool. So Tesla's trying to train you to use the brake pedal when you want stronger braking. Makes sense to me, last thing I want is to get half as much braking as I expected.
So with regen I get variable braking, but I get a reward (more range and less brake wear) if I plan ahead enough to make it work. However if there is surprise or immediate need for more braking then the brake pedal is there. So it's pretty much the best of both worlds, once you get used to it.
In Teslas, any time your foot is completely off the accelerator, you're getting maximum regenerative braking. If you then press the brake pedal too, you're getting maximum regenerative braking plus friction braking.
And their increased weight makes them much harsher on roads than normal cars. They wear down roads faster, and I suppose they also produces more particle pollution than normal car for this reason.
Threads like this read like EVs are double or more the weight of an ICE car.
EVs are a couple hundred pounds heavier in average than an equivalent ICE car. In terms of road wear, it's still a rounding error compared to industrial trucks.
Yeah, that's my point. A single garbage truck is going to do more wear on the roads than thousands of passenger vehicles. Anything besides industrial vehicles is negligible.
The rear tandems of a semi or heavier straight truck (garbage truck, dump truck, etc) occupy roughly the same road area as your car and may be carrying the weight of ~10x your car. The contact pressure is also much higher (100+psi tires vs your 20-40 or so).
A typical garbage truck has 2 or 3 axles. Let's assume 3 to be conservative. A fully loaded garbage truck weighs around 50,000 pounds. That's 16.6k pounds per axle, vs a Tesla Y's 2.2k pounds per axle.
Doing the math, a single garbage truck does as much road wear as ~3,300 teslas.
Yeah turns out an electric drive train is much lighter than a gasoline one which offsets the battery weight somewhat. Gasoline engines aren't light, nor are the transmissions. Currently I think the weigh penalty is about 15-20%.
My guesstimate is if they can increase the energy density of batteries by 30-50% the weight penalty will disappear. Some of the reduction is the weight reduction of the battery and some is due to cascading effects on the rest of the car.
Typo, fixed. I could have sworn I typed "couple hundred pounds".
But to your point, a bmw 430 is also around 500 pounds heavier than a Honda Accord. Nobody sees a BMW and freaks out about tire wear. But people seem to hyperfixate on any small negative of EVs.
> But to your point, a bmw 430 is also around 500 pounds heavier than a Honda Accord.
At the heaviest weights, yes, but the heaviest Accord weight and the lightest 430i weight are only 148 lbs apart... and the Model Y can weigh in almost 400 lbs heavier than the heaviest of 430i's.
> Nobody sees a BMW and freaks out about tire wear.
You mean, so long as it's not an EV? ;-)
Seriously, nobody freaks out about a BMW 430i's tire wear, because that of the branding of the car. It's like freaking out over coffee increasing your heart rate.
> But people seem to hyperfixate on any small negative of EVs.
Be fair, those aren't comparable cars. BMW Model 3 and the Tesla model 3 are pretty similar in size, weight, and cost. The fastest of both is AWD and the Tesla is 4072 pounds and the M3 Competition and M3 Touring (the 2 variants with AWD) are 3924 pounds to 4116.
The non performance models are similar as well, the current BMW 3141-4023 pounds (the AWD are of course on the heavier side, and the Tesla model 3 is
3814 pounds.
Because of the weight scaling characteristics (damage done corresponds to fourth power of axle weight), it’s irrelevant if trucks are allowed on the same roads. The damage increase done by EVs is probably not even worth considering.
Any light vehicle traffic is basically inconsequential for any road build to handle any amount of medium trucks or heavy trucks.
Complaining about the 9000lb EV hummer makes for some great circle jerks among the demographics that hate people who drive normal hummers but the road basically doesn't care about them.
Almost all EVs that are not Teslas, use blended regen with the brake pedal. When you press on the brakes, regen is used for light to moderate braking and the friction brakes only come into play on hard braking. Most EVs product little brake dust and their brakes last a long time due to this regen. Teslas are the anomaly here.
My curiosity here, but is it true as well for bikes (e-bikes or not) using disc brakes? As fair as I understand they are really similar with car's one...
