Hi All, my first post here but looks like a good active electronics forum.
I'm building a Thermoelectric Generator-powered camping stove much like the Biolite stove if anyone's seen it. Basically a camping stove with a TEG that powers a fan to drive air into the combustion chamber.
I've got it working using a basic circuit whereby I use a 9v battery to drive my fan at the start and then switch to the TEG as a power supply once the temperature is such that I'm getting enough current to drive the fan.
This setup is fine but what I'd love is a built in rechargeable battery so I don't have to keep changing them. I really don't know much about battery recharging and so i'm reading up on it but wondered if i could get any help here.
So, i'll have a battery to run the fan 'til the stove is warmed up, then I'll want to switch to TEG power and I'll want any extra power to charge the battery...how easy / difficult / complicated is this?
Thanks for any help.
