I recently got an ebike. In my case, it's the Jasion EB7 2.0. I'm very happy with it, but I'm looking for some information. I would like to maybe add solar panel charging to it, but I don't even know what questions to ask to ensure what I get would be useful. And that's where this thread comes in. While that's my specific question, I figure having a thread specifically for all things ebike could be fun. Would something like this do anything at all when it comes to charging my bike? I attached a screen shot of my bike's specs and highlighted the batter/charger part. Since I know nothing about this type of thing, any and all help is welcomed. Thanks! Attachments:

I assume the "charging port" is an output on the bike to charge a phone or some external device from the bike's battery.
If you have any specs on the charger for the bike that would be helpful.
Where are you going to put the solar panels? On the bike or at some fixed point where you plan on charging it.

Obviously size etc... would be a factor on something like that. Ideally, if possible, I would be able to mount something that is relatively lightweight that can add length to my ride. I see I accidentally put the highlight in the wrong spot. But that's the best info I have. I also have This Link which gives a little battery info Something like this.... |

If you continue the solar panels all the way round the bike, you might get to a power level capable of having noticed impact upon a draining eBike battery... my eBike battery is able to stress out the AC power supply charger, and do this for several hours. Now, a "wrap-around" arrangement of solar panels needs a "door". So, a hinged lifting point would naturally be necessary.. as well as a very beefy center stand! |

Looks like the charger output is 54.6 volts to charge the bike's 48 volt battery. Don't know how precise that 54.6 volt output is from the charger but I assume that it is regulated pretty close to 54.6 volts. While you can easily put enough solar panels in series to give you the 54 volts, that voltage is going to very widely depending on the amount of sunlight hitting the panels. The bike battery may not like these variations so you would have to put a voltage regulator on the output of the solar panels that would keep the voltage from going over the 54.6 volts and shut off if the output of the panels were to drop below that voltage. A simple diode would prevent the battery from backfeeding into the panels if their output went too low (there's probably one already in the battery pack) but you would still have to buy or build a regulator to prevent the voltage from going over 54.6 Volts. Definitely something that is doable.

I'll be honest and say it's a bit above my pay grade. I would be limited to looking for solar ebike chargers.

Once you are getting sufficient voltage front your solar cells, you need to feed a charge controller to manage the battery. There are plenty of options that can manage a 48V Li-ion battery. This is a quick search on Amazon. $40. www.amazon.com/dp/B087BC9X4S |

Bad news is my bike doesn't have a battery. Or a motor for that matter. Just peddles.
The good news is my cardiologist says I can start riding it again.

I was depending on my "normal" bike (not yet made into an eBike) to help with my health. But, it took a toll on the knee. So, a conversion kit was used to make a cheap eBike that I now use to get to choose between excercise pedalling, and just-get-me-up-that-ridiculous-hill riding. |

I don't have to use my bike to get from A to B, I just use it for exercise, so electrification would defeat the purpose. And there aren't much in the way of hills where I end up riding. |

Hills are just large enough and appear just when I want them least! |

for me, riding my bike would involve not doing something that needs to be done. so riding doesn't get done.
