Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with the embodiments and with reference to the accompanying drawings.

[0017] Such as figure 1 Shown is a flow chart of the control method of a preferred embodiment. The charging control of the supercapacitor charger calculates the size of the charging current according to the charging time, and performs current regulation. The charging process is mainly divided into five stages: charger charging current The setting stage, constant current charging stage, constant voltage charging stage, supercapacitor self-discharge, and trickle charging stage. Among them, during the constant current and constant voltage charging process, the charging capacity detection of the supercapacitor, the abnormal judgment process of the capacitance fault and the state health indication of the supercapacitor are carried out; the self-discharge stage is used to detect the leakage current of the supercapacitor or the ...

Abstract

The invention provides a charging control method for a super capacitor, which is characterized in that a charging process comprises a charging current setting phase, a constant-current charging phase, a constant-voltage charging phase, a super capacitor self-discharging phase and a trickle charging phase. In the constant-current charging phase, the charging capacity of the super capacitor is tested, and abnormality judgment, health analysis and treatment are carried out. The charging capacity of the capacitor can be calculated and the open circuit of the capacitor and the output short circuit of a charger can be tested in the constant-current charging phase, whether the capacitor is charged to the rated capacitance can be tested in the constant-voltage charging phase, and results can be applied in a health analysis and treatment control module. The protection for a load and the super capacitor charger can be realized, and the reliability of the system can be improved effectively.

Description

technical field [0001] The invention relates to a charging method, in particular to a charging control method for a supercapacitor with functions of charging failure identification and health state indication. Background technique [0002] With the continuous development of technology, the application of supercapacitors is becoming more and more extensive. Supercapacitors have strong specific power and are currently widely used in hybrid new energy vehicles, military products for instant start energy supply and braking energy recovery systems, and backup power for wind power generation systems. The provision of initial energy for supercapacitors requires supercapacitor chargers, and supercapacitor chargers and effective charging control methods have become urgent technical problems in this field. [0003] Currently used chargers and charging control methods cannot effectively identify charging faults, nor can they judge and indicate the health status of supercapacitors. C...
