Method and device for prolonging cycle life of supercapacitor

Abstract

The invention discloses a method and device for prolonging the cycle life of a supercapacitor. The method comprises the steps of: acquiring first capacitor information; acquiring capacitor temperaturerange information according to the first capacitor information; acquiring a first capacitor temperature limit value according to the capacitor temperature range information; collecting environment temperature information in real time to obtain a temperature information database; according to the temperature information database, calculating the temperature variation in adjacent time to obtain a plurality of temperature variations; inputting the plurality of temperature variations and the first capacitor temperature limit value into a first training model to obtain first output information ofthe first training model, wherein the first output information comprises first estimated time, and the first estimated time is used for representing time information for estimating that a temperaturereaches the first capacitor temperature limit value according to a change rule of a current temperature; and acquiring first reminding information according to the first estimated time. The technicalproblem that the service life of the capacitor is affected due to lack of monitoring and analysis of the using environment of the supercapacitor in the prior art is solved.

Description

technical field [0001] The invention relates to the field of supercapacitors, in particular to a method and device for improving the cycle life of supercapacitors. Background technique [0002] Supercapacitors, also known as electrochemical capacitors, electric double layer capacitors, gold capacitors, and farad capacitors, are electrochemical components developed in the 1970s and 1980s to store energy through polarized electrolytes. It is different from traditional chemical power sources. It is a power source with special properties between traditional capacitors and batteries. It mainly relies on electric double layers and redox substances to store electrical energy. However, no chemical reaction occurs in the process of its energy storage. This energy storage process is reversible, and it is precisely because this supercapacitor can be repeatedly charged and discharged hundreds of thousands of times. [0003] However, in the process of realizing the technical solution of...
