Hi there,
I am designing a hand-cranked charging system for a uni project in which I want to charge a small (18mah) NiMH battery.
I want to obtain all of the charge in around 2 minutes of cranking but this would mean that the charging rate would be 20-30C which i'm assuming is WAY too large and would destroy the battery.
My idea is to have a secondary power storage device like a supercapacitor and then trickle the charge into the battery over a longer period of time.
I just wanted some reassurance that this idea is plausible and if anyone has heard of this being done before for some advice of where to look.
Cheers
Sam
