Abstract

The invention relates to the technical field of solar insecticide, and especially relates to a charging circuit of a solar beneficial protection lamp and a charging method thereof. The charging circuit comprises a voltage acquisition circuit, an output filtering circuit, a charging current detection circuit, a charging current regulating control circuit, a high-frequency pulse output and boost circuit, a storage battery charging and discharging protection circuit, a storage battery voltage acquisition circuit, and a solar beneficial protection lamp control unit. Beneficial effects of the circuit are that through detecting voltage of the solar cell panel and voltage of the storage battery, the storage battery is charged in a boost method under the condition that voltage of the cell panel is relatively low, and multi-step constant current is used to prevent life reduction of the storage battery caused by charging, and high-frequency resonance pulse current reparative charging is used to relieve and eliminate crystalline phenomenon in the storage battery.

Description

technical field [0001] The invention relates to the technical field of solar insecticide, in particular to a charging circuit of a solar energy-saving lamp and a charging method thereof. Background technique [0002] According to the analysis of the charging circuit of the existing insecticidal lamp controllers in the market, most of them use the solar panel to directly output the maximum current when the voltage of the solar panel is higher than the battery voltage, and use the switching device to control the on-off of the solar panel and the battery. method to charge the battery. In this method, in the late stage of battery charging, when the charging current is still relatively large, most of the current is used for water decomposition. A lot of air bubbles will be produced. It is easy to cause the active material on the plate to fall off and affect the life of the battery. When the voltage of the solar cell is lower than the voltage of the storage battery, it cannot b...
