Problems solved by technology

[0003] However, supercapacitors are usually large in size. Vibration stress during product transportation, or corrosion at the operating site will cause connection failures on the connecting pieces on the supercapacitor. Once there is a connection failure in the supercapacitor, it will affect the operation of the product. Therefore, it is necessary to design a system and method that can effectively judge the connection fault of supercapacitors

Abstract

The invention relates to a super capacitor connection fault detection method and system, and the method comprises the steps: S1, detecting whether a power supply is electrified, obtaining that the system enters a power-on working mode when a detection result is yes, and executing S2; S2, judging whether a power-down operation identifier state is 1 or not, if not, calculating the voltage V at the two ends of a supercapacitor within t seconds, and executing S3; and S3, judging whether the voltage V is greater than or equal to an upper limit Vmax of the voltage value when the supercapacitor is fully charged, if so, determining that the supercapacitor has a connection fault, and if not, determining that the connection of the supercapacitor is normal. The method and the system ensure the judgment accuracy, and are convenient and fast.

Description

technical field [0001] The invention relates to the field of electronic products, in particular to a method and system for detecting a supercapacitor connection fault. Background technique [0002] As a new type of energy storage device between traditional capacitors and rechargeable batteries, supercapacitors not only have the characteristics of fast charging and discharging of capacitors, but also have the characteristics of energy storage of batteries. They have the advantages of high power density and long cycle life. is widely used. [0003] However, supercapacitors are usually large in size. Vibration stress during product transportation, or corrosion at the operating site will cause connection failures on the connecting pieces on the supercapacitor. Once there is a connection failure in the supercapacitor, it will affect the operation of the product. Therefore, it is necessary to design a system and method that can effectively judge the connection fault of the superc...
