Problems solved by technology

[0002] In the existing lead-acid battery charging technology, when the voltage fluctuates, the current changes relatively large. When the voltage is high, the current is too large. When the voltage is low, the charging current decreases, and the charging effect is poor.
In addition, due to the improper use of the user, especially after the lead-acid battery is discharged, the battery is not recharged in time, or the battery is damaged after over-discharging. Or the battery that is about to be scrapped is activated by strong charging, so it is very important to develop a battery that can be used to charge the battery that has been scrapped or is about to be scrapped to activate the battery so that the battery can continue to be used.

Abstract

The invention discloses a lead-acid battery charger and belongs to that technical field of lead-acid batteries, include a single chip microcomputer control module, power management module, Voltage Sampling Comparison Module, Current Sampling Comparison Module, The battery voltage identification module, the charging current indication module, the saturation display module and the reference voltagesource module. The signal input end of the single-chip microcomputer control module is connected with a time setting unit and a switching unit. The switching unit comprises a manual switch. The invention controls the single-chip microcomputer to output a low-level / high-level signal by turning off / off the manual switch. And then the lead-acid battery to be scrapped is strongly charged and activated, the signal output end of the single chip microcomputer control module is connected with a current sampling and comparing module, The voltage sampling comparison module and the input of the saturation display module regulate the comparison value of the control current sampling comparison module and the comparison point of the voltage sampling comparison module, thereby realizing that the power management module controls the constant voltage or constant current output of the charger, and realizing the purpose of constant voltage or constant current charging.

Description

technical field [0001] The invention belongs to the technical field of battery chargers, and in particular relates to a lead-acid battery charger. Background technique [0002] In the existing lead-acid battery charging technology, when the voltage fluctuates, the current changes relatively large. When the voltage is high, the current is too large. When the voltage is low, the charging current decreases, and the charging effect is poor. In addition, due to the improper use of the user, especially after the lead-acid battery is discharged, the battery is not recharged in time, or the battery is damaged after over-discharging. Or the battery that is about to be scrapped is activated by strong charging, so it is very important to develop a kind of strong charging that can be used to activate the battery so that the battery can still continue to be used. Contents of the invention [0003] The purpose of the present invention is to provide a lead-acid battery charger capable o...
