High precision battery monitoring system design

For real-time monitoring Pb battery voltage, current, operating temperature, battery capacity and other parameters, battery monitoring system was designed. Battery health level was automatically determined by the collected battery parameters. Network remote monitoring capabilities were achieved using CANBUS bus. The system hardware circuit design was mainly introduced, and a serious explaination was made on device selection and parameter determination. A specific description of the system software design was made to describe the analysis and explanation.
