The power battery or the super capacitor is usually required to be detected in the production process, and the equipment used for detection usually adopts a component-capacitance test power supply. The formation partial volume test power supply is easy to cause the test precision to drop due to the aging of electronic components and the influence of temperature, and the test data of the power battery or the super capacitor is inaccurate when the power battery or the super capacitor is charged and discharged, so that the test data can be monitored in real time when the power battery or the super capacitor is detected, and the formation partial volume test power supply is calibrated when the precision of the formation partial volume test power supply drops. However, the calibration of the existing component capacitance testing power supply is completed before the factory leaves, and the calibration cannot be performed again according to the used environment after the factory leaves, unless the staff of the factory goes to the field for debugging again. For the existing component-content testing power supply, in the process of executing calibration and inspection operation, professional personnel are needed, the automation degree is low, and the component-content testing power supply cannot be calibrated in time according to the running load state information of the production line so as to ensure normal use of the component-content testing power supply.
