Not to sharp on mechanics huh?

Back in the old days of early automobiles manufacturers where making starters (motors) and generators (power sources) all in one unit. These were mounted on the front of the engine and powered by the engine crankshaft during operation.

The same principle can be applied to an electric motor (engine). You expend a portion of engine output to generate electricity to charge the batteries. It would be impossible to achieve a full charge this way but could supplement electrical charge enough to increase range.

like I said though, the problem is heat. Heat already is a big problem with EV and adding in extra heat from the charging process is likely a deal breaker for this concept. I just wonder if these so called engineers pushing the EV narrative have ever even considered this possibility? I have little faith in that at this juncture as I view the whole initiative suspect.
WHAT? None of this makes any sense.

I'm honestly lost for words. You are certainly not mechanically inclined enough to be throwing around witty remarks implying I don't know what I'm talking about

You know that power is coming from the battery right? Now you're just converting it to mechanical energy and back again to the battery, introducing an generator and all of the losses that go along with it, for zero reason.

You know that electric motors are essentially just generators in reverse, right? That's how regen braking works. So when you want to slow down, instead of freewheeling, the energy goes back to the battery

You can't move power back into the battery that doesn't exist, so you'd be pulling more power out of the battery to turn your generator, only to then introduce an extra motor to bring it back in? I don't think you fully grasp how an EV works

Suddenly I see how there are so many anti-EV people out there, lack of brains!

I took your word on how experienced you are with coal generation plants a few pages ago, I now want to take that back...

If you can figure this out, you will be the first gizillionaire lol

You cannot create free energy like that unless you have figured out how to break the laws of energy LOL.

Hybrids would be the closest thing (not really but it would have the two motors with one to "charge" batteries), and even they max out at 60MPG.

If it were possible, Elon would have figured it out.

Best we have is regenerative braking that can provide some charge back to the batteries by using the motors to slow the vehicle down instead of conventional braking.

But even in an ideal situation (go up a hill of a certain elevation and then go down another hill of a certain elevation and use regen braking to slow the car down and repeat) will not give you unlimited range...

OK so everyone in an EV eat a big meal when at the top of the hill and at the bottom everyone take a massive $#!t to reduce weight and maybe it is possible with a vehicle LOL. :lmao:

This is certainly an unique case situation. Would love to see the long-term ability of it. But again, in this case the vehicle isn't really going anywhere.

Funnily enough, my power has been off for 6 hours. Guess my neighbor isn't charging his EV :rofl:

No problem here

Variation on Gravity Storage and a good implementation too. Gravity Storage of PV uses daytime power to raise a large weight via a motor/generator, then reverses the process at night.

I would be. 5 KW PV, 7.5 KWH storage, plus PV trickle charged backup to that, none of which requires a gas, diesel or propane.
I have 17kw PV, just waiting for battery prices to come down. I need at least 40kwh to make it the night to beat net metering

Build a REAL electric vehicle!
"Bloodshed" is appropriate. 60-0 in a fraction of a second will re-decorate your windshield. "kids"(whether 6 or 60 seem to think they're immortal...they ain't).

I'm grid-connected not grid-tied I use what I just have to from the grid, but I don't export. The power companies seem to using any method they can to discourage grid-tie, usually really high fees, etc. for equipment and system inspections., etc.

Then you add


Proves my point. This concept is not new either. Heavy equipment has been using this for decades. What is new is the introduction of the battery pack. It would not require going down hill to do this but that's fine, obviously you know everything already.

I can assure you with 100% certainty, that it would

Energy is stored in a battery, that then goes to electric motors which goes to the wheels. The ONLY energy that goes to the wheels is gravity and battery power

Where does your generator come into play?

If you are right, why don't we have unlimited energy? you could run one of your cars on a rolling road and get free unlimited energy

In the design of the eDumper vehicle it is a 100% certainty that going down hill produces the generating required for the battery system as well as the braking force required to control the machine.

EV uses an inverter to run the electric motors powering the wheels. The eDumper does not use an inverter. EV have Battery Management Systems (BMS) that control output and input to the battery system. This system could be adapted to control output from alternators attached mechanically to the power axles, both front and rear of the vehicle and modulate current battery input allowing for a percentage of charging current.

Regardless as I say, heat is the factor that must be dealt with and that is a problem that so far has not been addressed.

Ummm...Physics 101 will say to you that this WILL NEVER happen, you would gain NOTHING by adding a generator or Alternator to a Electric car to charge the battery unless you can come up with something that produces more than its taking in. You can't fight friction and win. Mr. Friction has won this battle EVERY time, many have tried, He owns the Energy Casino, and under our current understanding of Physics, The House will always win. I will say this, Our Understanding of modern day physics is changing rapidly with Quantum computing and AI, I do believe this battle will be won in the future but right now, Ain't happening with our modern day toolbox and understanding.
