hi there I am building electric bicycles and I have a charger question I hope you guys can help with. The bike runs on a 24volt battery pack powering a front wheel hub motor. The big issue with an ebike is range for me. For some guys it's speed but I like puttering along. I would like to increase the range so I have an idea.
I know that a 24volt brush motor will also generate 24volts when turned without a power supply. I can set it as a friction drive on the rear tire and have it turn with the movement of the bike. Either with the front hub motor or coasting or even with the pedal power. Now that is all fine and dandy. The problem is that if I hook it to the power supply to recharge it. The motor will drain the power and become a motor again not a generator.
So what I need is a one way diode type device that will only allow the current to go in one direction. It needs to be capable of a max 25amps at max 27 volts. I doubt that it will ever reach that load but it would be my dream parameter. Most likely it will be a couple of amps at 24volts i hope.
If you can point me in the right direction I would be most grateful ... thanks. ps i can wire a circuit if I know what to put in.
