EV Vehicle recharge

[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.

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.


SMH.

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.

You can't make more power than you consume.

Ok, now repeat after me,

You can't make more power than you consume.



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

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!!!

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.

Interesting, Thanks

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.

I wish we could get saved in a time capsule. I’d pay a lot to be revived in 20 years. Would love to see what comes of the foofarah.

Another 'interesting study'... cost per mile of operations of EV's....

Watch a Tesla owner blow up his Model S with 66 pounds of dynamite instead of paying $22,000 to repair it

Blowing up a Tesla
That's not going to buff out.Beyond The Press
The owner of a 2013 Tesla Model S was facing a $22,000 repair bill to fix a faulty battery.

He teamed up with several YouTubers to strap 66 pounds of explosives to the car and blow it up.

The resulting videos have been seen a combined 5 million times.

For the first 900 miles, Tuomas Katainen's modified 2013 Tesla Model S worked fine, he said. Then water leaks and error codes forced him to call a tow truck to take it in for repairs.

After about a month, the shop told him the faulty battery needed to be replaced, at a cost of about $22,000. In addition to the hefty fee, the work would need to be authorized by Tesla, which was apparently not very enthusiastic about prior work that had been done on the car.

Rather than shell out half the cost of a new Tesla to fix an old one, Katainen decided to do something different. He contacted some of his favorite YouTubers, including Lauri Vuohensilta of Hydraulic Press fame.

After removing the lithium-ion battery, motors, and other expensive components, the crew hauled the chassis out to an old quarry on the outskirts of Jaala, a remote village about two hours from Helsinki, Finland.


The demolition experts from the YouTube channel Pommijätkät (Bomb Dudes) strapped 66 pounds of high explosives to the car and surrounded the area with slow-motion cameras.

As they were finishing the setup, a helicopter swooped in and dropped a mannequin with the face of Tesla CEO Elon Musk, which they strapped into the driver's seat of the doomed sedan.

The crowd retreated to a blast shelter, where Katainen was given the honor of pressing the button and sending his former ride to vehicular Valhalla.

In the video, a charge can be seen racing along the detonation cord, setting off a series of blasting caps that break the windshield and loosen several body panels.

After a short pause, the 14 hotdog-shaped charges erupt into a blinding ball of fire, sending a massive shockwave rippling out from the car.

Footage from a drone flying through the cloud of shrapnel and smoke shows a gray and black smudge where the car used to be.

The videos of the explosion have a combined 5 million views.

The standard warranty on a Model S covers eight years or 150,000 miles but may be voided if the battery is opened or serviced by anyone not authorized by Tesla. The warranty does not cover "damage resulting from intentional actions," like blowing the car up for a YouTube video.

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.

Solar cells on an EV just doesn't work good enough to add any meaningful type of range. If you had 500watts (this is really optimistic) of solar capacity to the roof of a Tesla model 3 you would gain 3.5km/hour. So a 3 hour drive could gain you 10.5km if it's sunny and the battery is warm (IF all the cells were in direct sun light for the entire time). Would do basically nothing in the winter.

If you have a vehicle like the Aptera which is a hyper efficient 3 wheeler that has the aerodynamic drag of 1 Ford F-150 side mirror a small amount of solar charging can add significant range. 40miles per day of range in California.

Any kind of mechanical energy generator will detract from the aerodynamics of the vehicle which is probably the most important factor in EV range and efficiency. The model 3 should be able to get 150-160wh/km in summer conditions but this is a more accurate reflection of highway driving in winter conditions...

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.

Yes , and I have been schooled on that on here

Would be the same outcome as if you looked back 100 years
This idiotic behaviour can only go so far until you run outta other peoples money
And that wood stove won’t have bluetooth
