Dear people,
I'm working for a project to make an electronic circuits for the electronic system for a solarboat. We want to make the effectivity of the circuit as high as possible. Because we are going to do races with it.
Now we want to make it like this:
We have a lipo battery of 44.4V and 20Ah (we're using a PCM to charge and discharge), solarcells at 44.4V and around 30A, and a PM motor. (motor circuits is not included in this circuit I'm making).
The circuit should measure and adept the voltage of the battery and the solar cells constantly . the circuit should take in mind what weather it is and what the distance it is untill the finish line of the race.
Now we want to do it like this:
We want the motor to be supplied by the accu and the solar cells together (to get as close as possible to the nominal workpoint of the motor). Therefore we need to regulate the supplied current of the battery to make it last whole the race. this shoudl be done to connect a potentio meter at the gat of a transistor which at his turn is connected to the battery.
further we want to use switches to use different circuits as the weather changes (one for full sun and no clouds and one for clouds)
by example when it's cloudy we use the battery and the solarcells together to the motor input but when the sun suddenly breaks through there's going to be a power peak which the circuit should moderate the lead the extra power to charge the battery with or mabye a few condensators.
Now I know my english isn't that good so if there are any questions just ask.
But as you understand i like to have some tips/maybe better ways to do this or just to get started.
Thanks in advance
