Abstract

Abstract: The capacity of lithium battery is the main parameter to evaluate the health status of the battery, but since the battery capacity traceability system has not been established. Based on understanding the principle of battery charging and discharging and a battery capacity measurement uncertainty model, quantitative analysis of the factors that influence the battery capacity measurement is analyzed quantitatively based on the uncertainty analysis of optimization of lithium battery equivalent circuit model modification method. Through the actual measurement of charging voltage, capacity, compared with the model calculation of the voltage, capacity, it is judged whether the calculation value is within the uncertainty of the actual measurement, and avoid the lower reliability of the model caused by actual measurement deviation.

Key words: lithium battery capacity, evaluation of uncertainty, equivalent model validation
