Abstract: For improving precision of measurement in Battery Monitor System,this paper has made nearly all-round analysis and test on major sources of measure error of A/D converter.Based on the results,it provided concrete ways to reduce measure error and made a motion to enhance the precision of the measurement.Specially,it introduced the process and algorithm of error compensation which has been effective on controlling the measure error within the range of requirements of the whole system.The ways provided in the paper also is of great applicable significance to use other A/D converter.
