Hello,I would like to design a circuit which should help the user to determine the capacity of a battery by measuring some of its parameters mainly the voltage an current so it could determine the discharge time and then provide information using an LCD about battery life.
Some link here on the net say that there is a need of measuring the discharge current in terms of time and then calculate the Amp-hours basing on discharging time and display on the LCD.
Could you please suggest the way of reading the current with battery load and how the time elapsed is determined so that the amp-hour is determined?
Please help me to think and find good solution and design using PIC16F877A which is interfaced to an LCD fr displaying purpose.
I am able to measure the battery voltage but I am not coming to the point of measuring the current and discharge time which helps in calculating the battery amp-hours.
help please to deal with this
