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.
@@HansKeesom yes I know, I’m not suggesting it as a replacement to the plug. I just really like the idea of having any kind of a vehicle that relentlessly keeps trying to trickle charge itself. Especially when I’m in the middle of nowhere. I would trade my glass roof on my car for a solar panel in an instant. I don’t care if it’s only like 5 ish miles a day. 5 miles is not nothing.
@@lyfebehyndbars9729 Theoretically I like to agree but the thing is costs : it is cheaper to buy a second or even third normal e-bike battery and put them in a panier instead of a trailer plus solarpanel plus charge controller etc. -weight : it is lighter to have a second or third battery then having a trolley and solarpanel -drag : you will have less drag with a second or third battery. The drag of the trailer is not likely compensated by the generated electricity....
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
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.
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...
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!!
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.
The big question is why are all vehicles not using this method? Firstly they too heavy, and if everyone rode bikes they would need alternatives when it rains a lot of the time, a simple covered road with battery change stations every mile, the charge stations are solar powered simple
Your solar panel should have a blocking diode in the panel itself so you don't need the extra external diode. As you note, charging the battery without a charge controller can overheat the battery and cause it to catch fire. Not a good idea.
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 ?
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!
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
Doesn't your battery have a BMS that will protect against overcharge? It seems likely... if so, that is essentially the same as the original solar charge controllers (before PWM).
Correct me if I'm wrong but your batteries have built in BMS. Wouldn't that stop charging before any damage? Drew Builds Stuff channel has a solar charging quad cycle you might like.
The Kobalt 24V batteries have BMS. But it only protects the batteries if you use a Kobalt charger to charge it or a Kobalt tool to discharge it. It has no protection if you just tap into the (+) and (-) terminals.
These are very strange results. Your solar power outputs 54.7v, but manages to charge a battery that is at over 60v. This is not supposed to conform to physics. Open circuit voltage, as I understand it should not be dangerous if no current is supplied, and especially not if it matches full state of charge of battery. However, I don't understand your video/measurements possibilties, and one explanation is that I don't understand electricity.
ther are much easier ways then that , man has too catch up too this day and age. but i will say this is superb am shocked you pulled this off not saying i can build this setup. great work great video
