The circuit structure and the sampling principle of single battery voltage detecting circuit were introduced. Switching network timing of single voltage sampling was described, and voltage conditioning circuit parameters were calculated. There were some errors in the measurement results. Through the analysis of the main sources of the errors, corresponding correction strategy was given. The test results showed that experimental results after correction were more accurate and stable.
