Im not asking for quip answers mate, this is asking what is the power output, how does that equate etc etc. Obviously its not like plugging into the mains, but i reckon if people were stuck, with no power source, but they had a small generator, a bike, loads of wires, batteries and their life depended on it, I'm quite sure we could come up with something.
So back to my actual question.
Well what is actually needed to recharge a 625wh battery ?. My charger is 4A.- the output is 36v.
It takes about 5h to recharge that size of battery from flat, using the 4A charger.
I would be asking how much does a human pedaling away generate ? Obviously i think it would depend on what the generator puts out. Its a matter of doing the math.
Now im not suggesting it can be achieved in an hour, or even one day, but could it be done within a reasonable time frame of say 3 or 4 days of pedaling or less, i dont know which is why i was asking the people here you understand these things Flecc
I would also point out , that theres no road surface, nor wind resistance to worry about. you arent trying to propel a 100kg mass, just turn a wheel to turn a second wheel to generator power, which you then feed either into some sort of storage unit, or the bikes battery direct.
Many canal boats and small yachts we have wind powered generators for keeping the boats batteries topped up, and as those do a job and work well at it, and as we arent powering anything thats causing a constant drain, it should i would have thought be a simpler process.
I also know that in the WW2 the military had hand powered generators for powering radios. Plus obviously the one made by Trevor Baylis.
So
@flecc. The answer is not about getting fitter, or riding a non ebike, its about the generating of electricity that can be used elsewhere.
Maybe one day I'll show you my BayGen radio.
