Method and device for detecting highway composite pass card and storage medium

The invention is suitable for the technical field of equipment detection, and provides a detection method and device for a highway composite pass card and a storage medium, and the method comprises the steps: reading the initial residual electric quantity of a CPC card, carrying out the power consumption test of the CPC card through a power consumption model when the initial residual electric quantity is greater than or equal to a first threshold value, and carrying out the detection of the CPC card after the power consumption test is completed. And reading the current residual electric quantity of the CPC card, and finally determining whether the battery module in the highway composite pass card to be tested is abnormal or not based on a difference value between the initial residual electric quantity and the current residual electric quantity. The design and practice thought of the power consumption model is provided, and the power consumption condition of the CPC card can be determined through the electric
