Battery Life Estimation for Embedded System

A battery system consist many battery cells with different characteristics to achieve reliable,efficient and extended utilization of battery. The battery management system provides individual level of battery. This level of b attery provide information about state of charge,state of health of the battery. The current battery technology provide module level with voltage sensor. The object of this project to determine and the display the supply frequency. This can be done by usi ng c8051f996DK. This designed circuit consist liquid crystal display(LCD),Zero crossing detector(ZCD),transformer,variable power supply unit .The supply power is sinusoidal in nature given to the step down transformer. This output of the transformer are also in sinusoidal in nature given to the zero crossing detector. When signal cross the zero then zero crossing detector send high signal to microcontroller . Based on the sourc e code given to the 8051 microcontroller. It detect the number of zeros crosses and convert into frequency and display on the LCD. https://www.ijiert.org/paper-details?paper_id=14007
