Pulse charging method for increasing voltage in floating charging stage and power charger

Abstract

The invention relates to the field of power chargers, in particular to a pulse charging method for increasing voltage in a floating charging stage and a power charger. The method comprises the following steps: step S10, entering the floating charging stage and increasing the voltage value of the current charging voltage; and step S20, reducing the voltage value in a sectional manner until a lead-acid battery is fully charged. Compared with the methods in the prior art, the pulse charging method for increasing the voltage in the floating charging stage and the power supply charger are designedso that the lead-acid battery is easier to be fully charged, and the problems that the capacity of the lead-acid battery is virtually high due to aging of the lead-acid battery and a charging adapteris liable to misjudge are avoided; besides, the damage to the lead-acid battery is reduced so that the lead-acid battery is at a proper temperature, and the phenomena that the lead-acid battery is damaged and even explodes due to overhigh temperature of the lead-acid battery caused by long-term high voltage can be prevented.

Description

technical field [0001] The invention relates to the field of power chargers, in particular to a pulse charging method and a power charger for pulling up a voltage in a float charging stage. Background technique [0002] Power adapter is a power supply conversion device for small portable electronic equipment and electronic appliances. It is generally composed of shells, transformers, inductors, capacitors, control ICs, PCB boards and other components. Its working principle is converted from AC input to DC output. At present, in the floating charging stage, the function is to compensate the charging to fully charge the lead-acid battery, especially for the lead-acid battery with serious aging. [0003] However, the existing float charging is still difficult to fully charge the lead-acid battery, and the capacity of the severely aged lead-acid battery is falsely high, which may easily cause misjudgment by the charging adapter.
