Battery Monitoring's basic function is to monitor battery status. It can be able to timely report the states to user in order to maximize using of battery storage capacity and cycle life. We use 1-wire bus digital sensor. The sensor is DS2438.It can detect voltage, current, power consumption and temperature of the battery. 1~Wire Bus is a technology that it can communicate with the peripheral only with one line. This can greatly save system resources. Digital sensors integrates A/D conversion and the measured data is the digital traffic. This can improve system integration, simplify the circuit.
