I moved your post over here as you posted in the feedback forum:
Feedback and Suggestions Forum for providing feedback and suggestions about All About Circuits, including corrections to the e-book. This forum is not for getting help with technical questions.
Welcome to ACC! Are you a member of ASME (American Society of Mechanical Engineers) or does that stand for something else?
As Bertus asked, first question is, what is this for? Based on your name and project description, I'd venture to guess this is for a school project revolving around a formula or standard automotive car. If so, we can help as long as this does not modify or go into said vehicle.
Second, does your circuit need to start and stop a battery charger or just monitor it and measure the length of time it took to charge the battery?
Third, what is the make and model of the battery charger in question?
