Hello i'm looking into doing a project combining pedal power to a generator with a typical 72v lithium setup.
This would be extremely similar to many of the pedal powered 12V packs, but I haven't been able to find any solid information on what I need to do to make this work with a 72v lithium pack.
I know this would be possible by adding a second motor controller, and treating it like regen, but this is expensive, surely someone has a better idea on how to do this.
Gear reducing and such is possible in this setup, so rpm isn't a big issue, but i've gotten the impression by reading about motors that I can't simply just spin it as fast as i want to get the desired voltage as it will cause the motor to overheat.
I've seen some circuit designs for step up converters for this type of thing, but have no idea how efficient they are.
An adjustable setup would also be of great benefit, allowing people with greater pedal power to change the setting and dump more amps into the battery.
Anyone got any insight on this?
