Problems solved by technology

[0002] At present, the battery chargers on the market are either constant current and constant voltage, or two-stage charging, that is, constant current first and then constant voltage. Often, the battery is not fully charged or overcharged, which will affect the life of the battery. , and the current drops slowly during constant voltage charging, and it usually takes a long time to fully charge

Abstract

This invention refers to an automatic electricity charger, which contains rectifying filtering circuit, auxiliary power supply, power conversion circuit, pulse modulation control circuit, driving circuit, control circuit and overcurrent and overvoltage protection circuit. Said invention can automatic stage charge without people monitoring to the lead acid accumulator, the voltage can be automatically monitored and start charge and stop charge when the voltage is dropped or charged full.

Description

Technical field: [0001] The invention relates to an automatic charger for automatic stage charging of a sealed lead-acid storage battery. It belongs to the field of electronic technology. Background technique: [0002] At present, the battery chargers on the market are either constant current and constant voltage, or two-stage charging, that is, constant current first and then constant voltage. Often, the battery is not fully charged or overcharged, which will affect the life of the battery. , and the current slowly decreases during constant voltage charging, and it usually takes a long time to fully charge. Invention content: [0003] The object of the present invention is to address the above-mentioned defects, and propose an automatic charging device for automatic staged charging of sealed lead-acid batteries, which implements automatic control. The technical solution of the present invention: its structure is composed of a rectification and filtering circuit, a power...
