An electric motor has one rotating part...the rotor.

High reliability of EV's is documented...although there were some drivetrain issues with the early Teslas. Low maintenance has also been documented and is a no brainer. Brakes are used a lot less in an EV, really its just wiper blades tires and of course shocks. We have gone a couple years and still no maintenance...and of course never a visit to a gas station.
Still haven't been able to find any of the documentation just random platitudes about electric motors have fewer parts so the must be more reliable.
I'm looking for actual factual data that shows fewer maintenance issues based on real world numbers. I've done some google searches but it all gets bogged down in people claiming it but never providing numbers to back it up.

When they make an EV Pickup that can tow across country, I'm in. Until then, there isn't an EV made that I can drive to and from work every day, which is 120 miles round trip. I can't sit in a car for very long, getting in and out is painful, which is why I drive an F150 everyday, which pound for pound equates to a Hybrid in gas mileage. Lets see a Prius get 20 MPG while weighing 6000 pounds! ๐ My previous car was a Fusion Hybrid, and going up to 47 MPH on electric was pretty neat, but didn't go very far.
Mybe 20 years from now, power cells will make it possible for long range travel, but for now, the best marriage would be Hybrid gas/electric. LiOn packs have grown in Mah, while getting smaller, and now there is newer LiPo technology for faster amp draw with less heat, but LiPo still is a dangerous tech to work with. I fly RC planes, and a few of them run on LiPo. A crash with one of those usually ends up in a fireball. Those are from packs that fit in your hand, so imagine what the belly of a Tesla would look like when it gets punctured. When the seal is compromised in a LiPo, and they have energy still stored, which in an EV would be roughly 80% capacity, they flash immediately when Oxygen hits them.
I had a 3300 Mah 3S pack with a bad cell, so took it to the range, and put a 22 through it. It went POOF into a large flaming mass almost instantly. Scary.
If anything, better hope that the cells are well protected in an EV, all it takes is to pierce one cell for them all to go up.

Care to share reliability figures (not random platitudes about it has fewer parts so it must be more reliable)?
Fact is the engine in an ICE is incredibly reliable. It's normal to get 200-250k miles with no significant engine work beyond an annual oil change. Most work on cars is electrical, suspension, brakes and tires. EV's have all those things.
For 90% of the trips, a low range EV is fine. As a 2nd household car, I think it's a great option but most people do take trips in the hundreds of miles at least a few times per year and then even 300 mile range EV's become a hassle. If your EV is a 2nd car, it's no big deal as you can use the ICE car. If it's your only car, you have to give up that capability or deal with the hassle. When you are paying a 1/3 premium over a comparable car, most people won't accept that and it shows up in the sales numbers.

We only travel 16000 KM per year (maybe a little more some years) so they work fine for us. Maybe 2 or 3 longer trips per year of about 500 km but most out trips are under 150 KM. Talking to friends and neighbours, many have similar driving habits. I think there will always be some who have to travel 500 KM regularly but most of us don't. I can't see why an electric vehicle that has 200 t0 300 KM of range couldn't be 100 percent solution for many....just not all.BenK wrote:

No problem handling the power and diesel-electric trains have nothing to do with efficiency. Direct drive would be more efficient. The problem is the transmission to get a train with 5 engines and 100+ cars moving from a standstill would be massive, complicated and virtually impossible.
Bullet trains solved that storage issue with live wires or rails and are all electric. Heck, even the mag-lev bullet trains are all electric but not rotating motors.Bullet trains don't have big power demand relative to large freight trains. Big difference with roads is bullet train lines only handle bullet trains. You will never see a large freight train running on a bullet line. Since they only handle bullet trains and due to the speeds they have positive separation from all other traffic and pedestrians, it's easy to build in high voltage power lines.valhalla360 wrote:BenK wrote:

The issue is not the distribution system. The distribution system already exists for just about every house and commercial building in the USA.Yes, but limited in most, unless rewired with +50 amp and higher than standard 110/120. Maybe tap into the dry/stove line.

Go back and read up on the Graphene batteries and better yet would be capacitor batteries
Amperage really isn't a big deal with electric cars. Yeah, it's slow but 15-20amps for 8hrs overnight when power demand is low isn't going to tax the system. Apartment dwellers will have issues but your average home owner with a garage is already set up.
The issue is that batteries are expensive, hold very little power (relative to size and cost) and they take a long time to charge (even with the high powered chargers).Again, go back and read up on the newest types of battery IP

Your comment is based on lead acid and Lith-Ion types

The idea that it is foreordained that electric will take over because gas took over from horses is false logic. Gas took over because it was better.

I'm well aware of the plans. I'm a traffic engineer and have a couple projects that work with the auto companies on new technology.
Plus check out some countries plans to ban ICEs and replace with electric in the near future
I'm also well aware of the plans to "ban" ICE. Ironically near future is 25-40yrs out. Conveniently long after the current crop of politicians is long gone. It's easy to claim you will do something when you know darn well, you won't have to actually do it.
I think electric cars will do OK once people get over the idea that they are fully functional the same as gas cars. If you are commuting 10miles to work and have a 2nd car, they should be able to produce a basic commuter electric car for comparable price to a gas commuter car but if you need a car that can go 200-300miles (and not come home to your garage at night), it starts becoming a big hassle to try and make electric work. Even if high power chargers become more common, high power means a half hour for partition charge and longer for a full charge and 200+ mile range means you are paying 30-50% more for the equivalent car.Buddy lives south of Watsonville and commutes to my area...Silicon Valley since the early 90's and drives an old 80's VW Bug that he converted to all electric with lead acid batteries in the trunk, rear seating area and even in the engine bay
Conveniently you ignored cost, complexity and other issues in your comments. If it was easy and cheap, there would be no need for ICE "bans" or govt subsidies. Electric would within 5yrs drive ICE into the history books. As a result, I have to assume, this is all talk with no substance.
About 150 miles round trip without running errands. With errands just under 200 miles
Around 2010, he bought a Prius and added about 500 lbs of Lith-Ion batteries from Zero Bike (Santa Cruz) and now has about 500-600 mile range...
He is an engineer and we noodle Capacitor Batteries all the time and the issue is that the controllers are not there just yet. They have them for bicycles and motor bikes but the amperage is too small for a car to have the power needed for our performance needed/desired and regenerative braking

By the end of the 19th century, once-vacant lots around New York City housed manure piles that stretched dozens of feetโoften between 40 and 60โinto the sky. The problem of horse manure had quite literally become larger than life.
And the problem comprised more than just excrement. When a horse, worked to the bone, plopped over dead, the city then had a rotting carcass to address, not to mention the flies and road congestion that accompanied it.
