The Future is here...........look for the Ram

[hammersley]

This eliminates RANGE ANXIETY for Electric Vehicles... ... ... . game over!

OK - 1st step BUT a Huge one... ... ... this is where we need to go... ... ... . a pickup version that uses the engine to produce the electricity to drive the rig... ..... we need to get the current drivetrain that we have out of the rig. (no driveshafts/transmissions/axles/read ends/transfer cases etc) and replace with an electric motors battery/direct conversion IS THE FUTURE... . watch the video - you'll see a RAM in there..... sure only 1/2 ton now - but the next step will be a small one... . In 50 years the current truck propulsion will look as ancient as the ones in 1900 look today!

Now that looks interesting. I hate hybrids, both mechanically and the reason they exist. But this looks like it could be a real useful technology. However, charging a electric vehicle from the grid only displaces the emissions for the engine to the power plant. And, if that isn't nuclear, what's the point? It may be more efficient to charge it (I have seen no numbers) but at what cost?



I thought it was funny how he danced around the cost of the vehicles. My translation - they don't care about the cost, they can just pass it on to their costumers. And it's too expense for market forces to justify it. I'm sure there is money some government seized at the point of a gun (taxes) funding this little endeavor for reasons that have nothing to do with logic or reason.

A electric Motor at each wheel would give you four wheel drive capability.
The bed could hold battery's and the engine would start when needed to act as a generator.

Plus the huge mechanical/electrical

advantage of almost ZERO loss in efficiency - electric drive is so much better in all aspects... 100% torque instantly - almost NO MAINTENANCE--greasing drivelines/transmission issues - differential and transfer cases. . you name it... ... . Look at how much all the driveline gear weighs on a 4x4... it must be at least a ton... ... that would be eliminated with a far better system! When these become mainline we'll throw away what we drive today - except for nostalgia..... Remember Really HD equipment is ELECTRIC drive!!! These can be run with a very small gas/diesel powerplant that ONLY generates electricity..... it provides enough power that you never have to stop an recharge. The 40 mile range limitation isn't much of an issue with this setup... .

4 electric wheel motors is something that should have happened 50 year ago.



Acceleration, braking, speed control, it all can be done with electric wheel motors.



Folks would have to re-learn how to drive of course, and that is probably one of the bigger hurdles to overcome. Seems most of society can barely function to inhale and exhale let alone drive something like that, but here's to hoping!

Strictly a statement. Energy conservation has has always been one of personal virtue. This technology and other green energy concept vehicles will never be main stream.



Companies like PG&E are only resorting to this to keep the FEDS out of their backyard.

They said the same thing about the horless carriage......

I'll bet in 20 years you will eat those words

Hey Hammer



I haven't seen very many posts from you in quite awhile, how are you?. I remember how ****** you used to get when the diesel prices were through the roof#@$%!



If I were you I would get one of those Obama rigs in the garage and be ready to go when the $4. 50 diesel prices return:-laf.

They are going to have fuel there before

we can buy anything else... ... just ruining the economy for everybody else... . these rigs will stop that in a heartbeat... . and BIG oil Knows It!

i've been wondering why vehicles weren't design more like a train's power train.

diesel electric with battery for low speed in town use. would be very efficiant.

Many people miss the distinction between a hybrid electric vehicle and an electric drive vehicle. They are not the same thing. Heavy mine trucks and locomotives use a diesel engine to drive a generator that supplies electricity to wheel motors. All of the energy to drive the vehicle comes from the fuel in the tank that the diesel engine converts to mechanical energy. The maximum power output from the system is governed by the maximum power of the IC engine.



A hybrid electric vehicle is one that has two sources of energy: a fuel tank and a battery. The IC engine converts chemical energy to mechanical energy, and the motor converts stored electrical energy to mechanical energy. But in most hybrid vehicles today, the maximum power of the system is not equal to the maximum power available from the engine plus motor. This is because electric motors usually make their maximum power at a lower speed than the engine does.



The problem with IC engine propulsion is that once fuel has been pulled from the tank and burned, it cannot be returned to the tank. An electric propulsion system has the advantage of recapturing part of the vehicle's kinetic energy by using the wheel motors as generators during braking to recharge the battery. This is the HEV's main claim to usefulness. They actually get better fuel economy in stop and go driving than they do on the highway. But you don't get something for nothing; the extra weight of the electric motor and battery actually hurts the highway fuel economy of the car.



Now there are people out there working on plug-in hybrids. These vehicles use large battery packs to extend the electric-only range, but at the expense of overall vehicle usefulness. Batteries that give useful range are so heavy that they cut down on the vehicle payload. The most advanced lithium-ion batteries available today weigh 60 times as much as gasoline or diesel for the same amount of stored energy. This means that even though electric motors are about 3 times as efficient as IC engines, you would have to stop 20 times more often if your electric vehicle's battery weighed the same as the fuel tank that it replaced.



What this means on my truck is that the 238 pounds of diesel fuel that gives me 600+ miles of driving range would turn into 4760 pounds of batteries that would use up the available payload capacity, making it useless to do real work, other than hauling me around.

Still think the answer is power just like a RR loco = = the only thing a battery does is start the engine - - electric motor at each wheel for power and dymnamic braking

 

[tempforce]

with no drive line losses, it should be more efficient. only issue i see is low speed / high speed operation. do they use different sets of windings in the motor. to act like a gear box. as i've seen where train engineers, use two levers for acceleration. one for throttle stops and one is the speed control. i may be wrong here. so if some one realy knows please set me straight.
thanks...
