Infinite range solar powered electric bike without a charge controller?

Testing a concept solar powered ebike without a charge controller. The result was surprising!

I would have tried a capacitor at the panel output, then a buck boost circuit to give the stable voltage, thank you for taking the time to make this video, i always looking forward to seeing your next videos

Excellent demonstration of the usefulness of a solar panel on a mobile electric device! I really wish more companies would take solar as a supplement to the battery more seriously.

You need a longer tongue for your trailer so you can mount the panel more forward. Your weight distribution will be better and you won't need 25lbs in the front of your trailer.

Great experiment! It's something I was thinking of trying in the future

its the wind lifting the nose of your solar panel at higher speeds, thats why its fish tailing. with some aero parts on the nose, it will perfect haha. great video

[JackButlerVideos]

i wonder if you could use the battery as the weight on the trailer instead of carrying a dead weight that does nothing? Also where is this bike track? It looks great!!

[goojy]

can the ebike run and charge from the charger and do charger have charge controller i meen by that to found the safest way to charge wile on the go and discharge same time in a balanced way and did any one try wind generators with the solar on the roof so no fish tail same time ?

I am thinking this would be awesome as a rickshaw with the solar panel as the canopy.

with the new battery technology comming you wont need any power input for quite some time.
many years ago on tv news a teacher drove a fibreglass buggy from one side of the usa to the other side using wind turbines, no internal combustion engine.

Mindblowing sir!
Your bike looks like a laboratory =)

Nice idea...how about using 2 smaller panels with a pitch in the center. You'll never get full power on both but a lot more on the one facing the sun. No matter the direction of the sun or the direction you're traveling in, you will capitalize on higher input from one panel because of the better angle. At noon it will be a compromise but still have a high enough input. Second option is a smaller pitch with 2 different sized panels. Good luck...

What if you use the second battery on the back to weigh it down where the weight is have the solar panel charging the second battery while you ride and then swap batteries out and start to charge on the first battery that was on the bike

[xiaoka]

Awesome.

Now do a sun tracking actuated panel! 😅

[MichaelFergusonVideos]

If you would disconnect the solar panel when you check the battery voltage, would it still be as high as your readings with it conntected?

[richie]

So I need a 2 or 3 amp dc charge controller ?

[peachsncream]

Why not move the axle to the back end of the trailer ?

[sshutupurface]

make solar tracker on the back, so your panel can move to correct angle of sun

I really wish there were more options for all-in-one MPPT solar / Li-cell balance chargers. Everything I see is HVDC panel -> 12v output, and then you need an inverter to turn 12v DC -> 110AC and then a battery charger for -> HVDC again. It's silly.

[ellenorbjornsdottir]

Wouldn't there be an issue with the panel dragging down the battery if the panel is outputting below its nominal voltage?

[sshutupurface]

very cool make us some more like a car from bicycle parts, super light

If you are in California, I would love to get more information from you. I am wanting to build a solar powered ebike similar to yours but a little less weight. Would love your input!
