EV Vehicle recharge

[rodd]

Why don't EV's make use of power generating technology to charge batteries. Such as alternators that are proven and on every gas powered vehicle now. Use they might use 1% more energy to turn them, but if they generate say 5% of the charging a 4% net increase. Go 200 miles instead of 180 on charge
Build in solar panels to generate power. Would work when parked or driving. Might gain 100 miles, so up to 300 miles instead of 180.
Have a couple of Ram Air turbines, hidden in grill, or even on top of car. Would work great when driving and if efficient enough, would turn when parked also. Maybe another 150 miles, so up to 450 miles on a charge and reducing grid power usage.
Also if stopped on a blocked road (BC), the solar would keep enough power to drive home when road opens.

I'm just throwing the numbers out for conversation, they aren't proven. My question is why isn't this being done.

I believe EV's are here to stay so please don't debate whether or not they are feasible.

I also think that Hybrids are the best option right now. Sister in Law in Chicago with Toyota Rav4 hybrid goes 6 weeks on tank of gas. Her previous Honda Fit went 2 weeks. That is amazing I think. She says only time gas kicks in is on freeway. As long as under 32-34 MPH it is electric.
Yes here in Sask, mainly high speeds for us farmers it wouldn't help, but every city vehicle would cut fuel usage.

Bingo, hybrid tech is 15 yrs old and proven but instead of developing that we have gone full unicorn.

Of course EVs are feasible just as soon as we double the power grid capacity and permit 100 new open pit mines, or just accept that NG will run these things instead of oil. Or elect only to drive them 3 times a week and use the sustainable bike paths or zoom calls.

Just because something is forced upon us, doesnt change the facts and the physics. Anyone expecting 2 EVs in every garage as daily drivers powered by solar and wind (along with their homes and local grid) should probably seek medical help immediately.

Something has to give in this equation. My bet is a drastic reduction in our lifestyle and mobility will come before all the other parts of the equation. No new mines have been greenlights, nuclear is still blocked. Only thing left is behaviour.

The things we could do if only the laws of thermodynamics could be done away with.

The addition of solar panels would likely even be a net negative as their added weight would work against the system.

As far as I can tell, in following the alternative energy and EV cheerleaders, what were formerly known as the "laws" of thermodynamics, have now been downgraded to mere suggestions, malleable according to the needs and wants of politicians and ignoramuses such as our very own troll.

And in response, how appropriate that Chuck liked a post suggesting that perpetual motion machines are the solution. Alternators and turbines on electric cars, both breaking the first and second laws of thermodynamics. Thank you for proving my point above.

I assume the original poster was trying to be sarcastic, and suckered mr. anti-science Chuck in.

Well played.

Anybody try one of those Ford Hybrid trucks ? I think that would work for me never was a fan of big fuel bills. Keep gas gusslers for the dirty jobs.

Its kind of a chicken and egg thing. As more Electric Vehicles get sold the shells of the vehicle will incorporate solar panels at more economical prices. There is a massive market for electric vehicles in urban centers. As they become driverless, you won’t even own them, but hire them like uber.

Unfortunately us rural people will get bent over. Electric vehicles will never work as good in remote areas with winter storms, long distances to travel and a lack of charging stations, but high prices of fossil fuel will quickly force people to electric vehicles. Tax gasoline or diesel fuel so it costs $12/liter and keep electricity prices at todays rates and electric vehicle sales will explode, even in remote rural areas. Depopulation of rural areas will continue happening at a fast rate.

Government policy is going to be the driver of what happens in the future, just like it has for the last century.

But back to the original question, yes vehicle recharge will get better and better. It is amazing how much improvement has come in the last 20 years. There are roll up solar panels, all sorts of things inside windshield glass, etc. Perhaps slower moving EV will be lighter and require less energy consumption. North America has been blessed with wide open roads and high speeds. Lots of congested areas of the world pack bicycles, motocycles, cars and trucks on small roads and 60 km/hr speeds is all that is needed. We like doing 100-120 km/hr, but could probably get by with 60-80 km/hr.

I wasn’t being sarcastic, just curious. I will research thermodynamic laws

I apologize for making assumptions.
Your first couple of suggestions are a perpetual motion machine.
The first law of thermodynamics states that you will never get more energy out than what you put in.
So it will take just as much energy out of your EV battery to drive the alternator, as what you get out of the alternator to charge the battery.

The second law states that breaking even is impossible. You will always get less out than what you put in. Since the alternator and drives have friction, and heat, and electrical losses along tthe way.

There is regenerative braking, which is exactly what you describe. Rather than convert forward motion into heat with a friction brake, you absorb that energy through a generator to recharge the battery.

Wait a minute.


Why didn't they think of that? Unlimited free power! Run a big alternator off an electric motor.


Hey, why don't we add propellers to an airplane, that are turned by the airplane moving forward, to power the airplane moving forward.

This is why. An alternator uses more power in KW terms than it produces. That reduces range.

Solar panels on roofs add mere watts of power per hour (small area) to a vehicle using KW per hour. The weight factor alone would negate benefits.

You can't make more power than you consume.

Let me repeat that.

Ok, now repeat after me,

Electric cars have regenerative braking. They recharge batteries when you decelerate converting the inertia into kilowatts.

I am all for EVs where they make sense. If I was a city dweller it would be very compelling choice.
Sounds like a fair amount of electric vehicles had to be towed in BC after all the mudslides. Ran out of juice keeping the heater on. At least you can dump a 5 gal can into a car and be on your way.
I was told $23k for a new a Tesla battery. Can’t verify that number though.
Another guy hit a deer and did body damage. Tesla doesn’t sell body parts to repair. Want the vehicle returned to them for assessment and it will only be repaired if deemed safe to do so.

[Landdownunder]

Easy peasey ya wombats.

There are times in life when you have to chose between paying a boatload of money or watching a very big explosion. Well, not really, but Finnish man Tuomas Katainen sure did. Katainen is a 2013 Tesla Model S owner who was told he would have to pay more than $22,600 to replace the battery on his car. For him, it apparently wasn’t worth it, so he decided to team up with a YouTuber to blow up his Model S with 66 pounds (30 kilograms) of dynamite instead.

Watch a Formula 1 Race, regenerative breaking is used to extend the range on these F1 cars, however the amount of hard breaking that can be 'harvested' is much more than normal highway driving... down hill grades would be the best net gains... if only we could have roads that we could coast down hill on all the time... without having to go back up!!! Cat had a 'breaksaver' option that only converted the energy into heat on class 8 trucks... F1 and E1 race cars are the best examples of regeneration systems to extend the range and length of their races without requiring a recharge for the race car batteries. a very interesting study!!!

Cheers

Simple solution. We just need to find that hill that all of our grandparents walked up hill both ways when they went to school. We could go the other way both ways.
Of course, the 2 feet of snow year around would cut into the efficiency of the operation.

Takes a dam good alternator to run all the TV screens , heated glass, backup cameras, heated seats, spot lights. air conditioning, power windows and power plugs to keep la'tte cup holders heated so that us rugged cattle and grain farmers can make it through the day.
