Hi, I´m a student on the Electronics school, and I´m working on an assignment which I have had quite a trouble to solve, so I was hoping that somebody who knows better, could help me.=)
It is basically about:
I have to charge two batteries with one source, but while the first battery is charged the second has to be used. So the circuit has to switch charging between the battery that is full and the battery that is discharged. Also it has to have an output from the battery, that is currently full. I should say that I´m working with two Ni-mh 1,2V 300mah batteries, the charger has around 2V and the output should be around those 1,2V from the battery, but I know there will be some voltage drops so the minimal output voltage has to be around 1,05V ( the closer to 1,2V as could be).
I know it is hard to understand from the plane text so I have a prototype circuit that I´ve made, I´m not saying it would work (I was definitely hoping that it would), in the circuit opening and closing switch means full and drained battery, and multimeters”1&2” are output to the battery or better said outputs for charging the batteries, it´s all theoretical so I don´t have any specific components (tranzistors, thyristors, diodes) yet, but if it would work, I was also hoping that somebody would help me pick them out for the best efficiency. (The components which are in the circuit are just for practice and don´t have to be good at all) Thanks, for now, I´m really hoping that it could be done, and that somebody would be so good to help me with it.
