Hello there!
I'm making a circuit that will be attached to a small wind turbine garden ornament. We don't want the turbine to stop spinning.
The circuit needs to be able to charge a battery when the wind is good, but i switch over to this battery for power when the wind is bad.
I will connect a generator a diode (that will then lead the current into the battery) which leads to a relay. This relay effectively will sense the wind strength as it will switch to a contact only with the battery, and no diode, when the current from the generator is low. This will then allow the battery to discharge back into the generator, which now becomes a motor.
My question is: What will happen to the current flowing out of the battery, through the relay when it's not connected to the diode, as the motor spins faster due to wind and battery power? Will it decrease or increase or stay the same?
This leads me to also ask.. how will i get the relay to switch back when the wind picks up again?
