Abstract

The invention discloses a method for testing a supercapacitor, comprising a test circuit, the test circuit comprising a control circuit, a feedback circuit, a microprocessor, and an LED display lamp; , the voltage, time, capacity function relationship to calculate the capacity of the capacitor under test, the measurement process is controlled by the microcontroller, and the calculation results are stored in the microcontroller and displayed; when the capacitor under test is charged, the microcontroller controls the relay and treats it The measured capacitor is discharged, and the voltage of the capacitor to be tested is extracted at a certain time interval. The data is stored in the microprocessor, and the capacity of the capacitor to be tested is calculated, stored in the microprocessor, and the measurement result is displayed. Compared with the prior art, the method for testing the supercapacitor can be used in servers, storage and other electronic products to realize the electrical testing of the supercapacitor, provide reliable data, have strong practicability, and be easy to popularize.

Description

technical field [0001] The invention relates to the technical field of supercapacitor testing, in particular to a practical supercapacitor testing method. Background technique [0002] Farad capacitors are also known as ultra-large capacity capacitors, supercapacitors, electric double layer capacitors, EDLCs, etc. Farad capacitors are capacitors made of the principle of inductive electric double layers formed between electronic conductor activated carbon and ion conductor organic or inorganic electrolytes. Small in size , large capacity, good voltage memory characteristics and high reliability. In terms of energy storage mechanism, it is highly reversible, has a long life, can be repeatedly charged and discharged tens of millions of times, and can be quickly charged and discharged under a large current (10 to 1000 amperes). There are broad market prospects for power applications in fields such as electric vehicles, communications, consumer and entertainment electronics, and...
