    Hi there,

    I have imported some 36 volt electric scooters. Would it be possible to fit a dynamo to enable it to charge itself while moving, if that makes sense? Not sure if this is possible but a diagram would be nice! :D

    Cheers, Tim D

    It's possible but you will lose energy. It's a variation of perpetual motion. The energy required to turn the dynamo has to come from the battery you are trying to charge, and since the dynamo is less than 100% efficient, you can't gain anything in the process. If it would actually work, someone would have done that long ago. Sorry. :rolleyes:

    you could invent a solar powered jacket and plug it into the scooter !

    Hi,

    Thanks for the advice. I could drive the dynamo direct from the rear wheel or like on the old push bikes dynamo straight onto the tyre to spin it would this actually work.

    Trying to recharge the battery from the motion of the scooter defies the laws of physics. You cannot get energy from nothing.

    You can attempt to charge the battery when the scooter is coasting downhill. You can also attempt to recover the energy when braking. This is called regenerative braking.

    In both cases the amount of energy generated is so small it is not worth the effort.
