Since the lock will probably be in motion when not not in use, couldn't you just use some kind of kinetic charging mechanism to charge the battery? Is kinetic charging not enough powerful? Or is the circuitry too complex?
- mehrdad 13y agothat will complicate everything! and also increase the cost. besides you can't harvest much energy from that kind of mechanical movement...
- bentcorner 13y agoMaybe store some mechanical energy in a spring to help reduce the amount of "stuff" that needs to be moved just by the battery?
- chid 13y agocheaper and simpler to have a replaceable battery.
