valve-regulated lead-acid batteries are extensively used in substation DC systems as a backup power supply
which have a space of utilization after retirement. In order to estimate the battery’s performance after retirement
in this paper a reasonable and simplified VRLA mechanism model is set up
then is discretized and solved by the Ritz method. Finally
the model is verified by charge-discharge experiments. The experimental and simulation results show that the mechanism model has a higher simulation accuracy
which lays the foundation for the analysis of aging state of retired batteries.
