Batteries are an important guarantee for the safe and reliable operation of the power grid environment.In order to provide effective reference for the selection and maintenance of batteries,a reliability assessment method for battery health status based on Internet of Things technology is proposed.Utilizing the Internet of Things technology to collect real-time working data of batteries,taking into account the factors that affect the reliability of battery health status and intuitive performance,the evaluation indicators are determined,and the specific values of the evaluation indicators are solved with the support of working data.The Analytic Hierarchy Process is used to calculate the weight of evaluation indicators,and by integrating the evaluation indicators and their weights,the reliability assessment of battery health status is achieved.Through empirical analysis,it is concluded that compared with the two traditional methods,the open circuit voltage and capacity evaluation index errors of the optimization design method have been reduced by 0.25 V and 5.3 mah,respectively.Applying the optimization design method to battery selection and maintenance work can effectively improve the operational stability of the power grid.
