I was given a similarly conditioned "hoopty golf cart" when i was about 12, by my neighbors. We put together enoigh batteries to fly around the proprrty at 48v instead of 36 like it was originally. (The battery trays were so rusted we could only get 4 12v in it instead of 6x6v anyway. It was rusty and bent up, but we rode that thing all over the property for a good couple years. Mom even used it to haul garden tools and such across the 4 acres we had, instead of using our ATV. This project brings back such nostalgia and fond memories for the dreams I had for mine. Im still not sure where it ended up. Similar to a lot of the toys I had good memories with, they would occasionally just disappear... lol So in other words, keep going Jimbo, if you want to, I'll be watching. I know a lot of us will.

I am pretty sure I was the only 10 year old with an oscilloscope of his own in 1973- and the adventures continued when I discovered getting a ham radio license to legally operate those radios I was putting together.

Good morning, Jimbo! and Happy Sunday from all of us at Misfitz Motorsports and Performance (MMP)! Our coffee cups are charged up, and ready to see this petroleum battery come to life! Have you considered using a buck converter to make the DC driver motor think it’s receiving a different voltage, in addition to the PWM you’re using? That could open up some exciting possibilities! we would be happy to send you one if you would like.

[@robotcantina8957]

Good morning! the project s still evolving, the PWM controller I'm using may actually be more than enough voltage and current. The sluggish throttle response is due to the throttle knob being awkward to turn fast enough. We will be working on that this week.

[@MisfitzMotorsportsGarage]

Oh, I understand completely, especially after watching your detailed breakdown! That makes total sense. I was thinking, though-if you were to use a buck converter inline between the battery and the PWM, it could 'trick' the PWM into always thinking it's receiving the proper voltage, regardless of the actual battery state. This way, you’d have direct and consistent control over speed through the PWM/throttle design. I’ve tried a similar setup with a long-range drone that had no mid-flight recharge capabilities. Same drone, same battery-without the buck converter, I’d get 15 minutes of flight time on a 250g 7-inch. With the buck converter? Up to 35 minutes of full GPS, video, and control until the battery was done. It made a huge difference! (Thank God for LiFe Batteries) Lead-acid batteries, while reliable, tend to experience voltage drops as they discharge, which can impact the performance of devices relying on a consistent voltage input-like your petroleum battery design. A buck converter can address this by stepping down the input voltage to a stable level that the PWM controller can consistently manage, regardless of fluctuations in the battery's output. By ensuring the PWM controller always receives an optimal voltage, the buck converter can improve the efficiency and responsiveness of the throttle design. It prevents the system from underperforming during periods of lower battery voltage while allowing the controller to operate within its ideal parameters. For a design like this, where stable and precise control is critical, a buck converter could maximize runtime and performance, much like it does in drones or other high-demand applications. This would enhance the overall user experience and system durability. feel free to shoot me an email [e-mail]. It would be great to speak on this further

While your playing with golf carts, check golf course mowers. John Deere 2500E TriPlex Greens mower has a 48v alternator for driving the reels. Jacobsen makes a similar hybrid and I believe one that drives the machine too.

[@CrustyShackleford]

What about all the energy that is lost between the local power plant and the battery when its charging? You've cut out a few miles of wire and quite a few transformers... Your setup looks pretty efficient to me!

[@bobirving6052]

How dare you suggest that electric power isn’t perfect and clean and free.

[@robotcantina8957]

Indeed, I reckon the loss percentage between the power plant and my outlet is much greater than the percentage of loss between the petroleum battery and the dc motor.

[@goosenotmaverick1156]

Losses are lower at extremely high voltages they're transmitting at comparatively. It's not perfect by any means but it's not much comparatively. The efficiency isn't necessarily gained with less losses, it's about the thermal efficiency of energy production that makes the largest difference. When doing something like this, you have to consider all the associated vehicles, other fuel, etc, to refine, transport and fill up your tank with a petroleum product. None of it is perfect, and their losses are generally shown in a different area when comparing smaller generation with larger generation.

[@nerd1000ify]

Small engine efficiency is usually rather awful compared to a large thermal plant burning the same fuel. Even a lousy thermal power plant gets 30% thermal efficiency. A small engine like the predator probably manages about 15%. That's a big gap to make up. On the other hand, the charging efficiency of the reaction battery on a golf cart probably isn't all that good...

[@tl1024]

Love the project, definitely continue. As a 17 year golf cart mechanic, i can say that cart was a "hooptie" 20 years ago. Also, spinning that 36v motor at 36v with no load is definitely risking overspeeding the motor, i usually use a 12v car jumpstarter to test motors with no load. And that motor will live happily on 48v (maybe more) if you decide to push it that far, just dont do it with the wheels off the ground.

[@noahsheehan7824]

Excellent work! I work in the OEM power supply industry, and I'm also a big gearhead. I really love the project you're working on, and I'd even be willing to donate power supplies to support your cause. Electric vehicles certainly have their place, but I've often pointed out that the large GE train engines provide a great example of how a similar system could work for cars and trucks. My idea is simple: use a "petroleum battery" with enough energy to power the vehicle at highway speeds and run the air conditioning and accessories. A smaller battery could be used to help get the vehicle up to speed and recover braking energy-essentially, what a hybrid does. I believe using a polyphase AC motor and controller would improve efficiency and enable effective braking energy recovery. People overly zealous for the concept of electric cars/trucks have approached for year and I tell them to do the math. Diesel fuel provides 37 kWh per gallon, and gasoline is around 35 kWh per gallon, with both weighing about 7 pounds per gallon. In comparison, you'd need 1,800 pounds of lead-acid batteries or 407.5 pounds of lithium-ion batteries to store the same amount of energy. Were if not for Lithium Electric cars would not make sense, then density is finally getting up to a usable range. Keep up the good work, let me know if a DC/DC converter or an Inverter would help your cause. But whatever you do keep having fun. :)

This setup is actually quite efficient, if you dial in the engine right for a single RPM. That's why hybrids get such great fuel economy. Diesel-electric locomotives do actually get a good efficiency gain from this. Though I guess your setup does basically use the motor as an electromagnetic transmission, so I guess the lack of a main battery to draw surge current from would kill the efficiency gain inherent in a hybrid system. And I'd hate to come across as an armchair engineer, so I'll mention that I'm currently designing a go-kart that employs a similar system but with a small battery pack. I'll upload a video when I finish it.

I could see doing some electromotive conversions on some of the old cast away electric carts around here. Thanks for your awesome work. Makes my weekends.

I find this concept fascinating. I didn't expect the series hybrid with the alternator to be as effective as it is. I built a trike with one of these motors and a Miata rear end almost 15 years ago, and it was powered with 4 batteries. I never completed the project but I have always wanted to resurrect it into something of a farm vehicle with 4WD. This gives me ideas...

This is the most entertaining electronics class i have ever taken. Thank you!

So awesome! Definitely going to need a arduino based PWM controller to adjust the voltage to the alternator! This could so easily be converted to a DC to charge controller for 24-36vdc for off grid solar/wind, this way at what 1100~RPM of the "petroleum battery" at high idle vs the 3600 at WOT fuel usage would be much less and still be able to charge a battery wall for off grid use, and/or pushing a golf cart with a few hundred lbs of humans down the road at a respectable speed. Can't wait to see what else you come up with! Keep em coming!!!!

Please keep going with the project. For longer I've been thinking of a hybrid go kart and all this information is excellent

Definitely think you should keep going with this, even though a 3-wheeled golf cart is a death-trap regardless of the power source. Is setting up reverse as simple as reversing the field polarity on the alternator, or do you have to reverse it at the motor?

[@robotcantina8957]

Since its a series wound DC motor, reverse is complex and requires a large switch to reverse the polarity of the field windings. Simply reversing the polarity of the alternator wont work because on a series wound motor the spin direction is the same regardless of polarity.

Continue with the project. In fact, you should add an external DC to DC converter to pull voltage from the alternator to charge the 12v battery and keep it full .

Another great episode. I haven’t heard the word hoop-d since the early ‘80s when I owned quite a few of them. You have the inner enginerd in me thinking… Drag Load testing: akin to mid-western style tractor pulls. Fuel econ vs power testing: will an early ‘90s 50cc moped motor power this thing? How how about a petrol powered 2 cycle string trimmer engine? You’d probably have to spend a few bucks on this one though. Edit: Just thought of one more: Off Roading a.k.a hill climbing: (like you might find on a golf course) trying to carry to grown mid-aged men up hill. That will test if the little engine can carry the load.

I can see a petroleum battery powered 3 wheel golf cart speed record at Bonneville in the future.....well maybe not. Yes, keep it going! Fun to watch!!! 👍

[@scotth9881]

I like it, and hope you continue. I always thought there would be a way to fix these electric carts without buying all the expensive batteries. And they can be picked up really cheap when the batteries fail.

A successful transportation contraption in the second episode! This is moving quicker than most projects on this channel. Maybe a small second alternator could provide the 12V source for instruments & the variable power supply, so you can fully ditch those toxic lead & sulphuric acid cells? Those things are nasty and heavy!

That alternator mounting is a thing of beauty.
