Abstract

The embodiment of the invention discloses a method, an apparatus and a circuit for detecting a super capacitor, relates to the capacitor detection field and solves a problem that a capacitance value cannot be detected. The method for detecting the super capacitor comprises transmitting switching control instructions to a switching control module at first, cutting off the to-be-detected super capacitor from a series-connection super capacitor set, transmitting gating instructions to a gating control module to enable a voltage detection module to carry out voltage detection during discharging of the to-be-detected super capacitor, obtaining at least two voltage values of different time from the voltage detection module, calculating a detection value of the to-be-detected super capacitor, determining and obtaining detection results. The method, the apparatus and the circuit provided by the invention are mainly applied to detection of electrical components.

Description

technical field [0001] The invention relates to the field of capacitance detection, in particular to a method, device and circuit for detecting supercapacitors. Background technique [0002] Supercapacitor is a new type of passive device, which has the characteristics of fast charging and discharging, reusable use and long service life, and is widely used in backup power supply systems. [0003] The so-called backup power supply system is a device that temporarily provides power to the electrical equipment when the main power of the system cannot supply power to the electrical equipment normally. The so-called system main power refers to the equipment that usually provides current for electrical equipment, such as mains power. The supercapacitor is the main component of the backup power system, which determines the power supply capacity of the backup power system to a large extent. In general, it is difficult for a single supercapacitor to meet the power demand of electric...
