Abstract

An efficient lead storage battery charging device is provided. The efficient lead storage battery charging device relates to a pulse switch device and is composed of a current detection circuit, a voltage detection circuit, a temperature detection circuit and a one-chip microcomputer minimum system. A battery is charged with pulse current, the battery is firstly charged with charging current, then the battery is discharged with discharging current which is greatly less than the charging current for a period of time, a pulse width modulation mode is adopted in the charging/discharging time, the charging time is set as 1S, the discharging time is set as 0.2S, and the charging efficiency can reach 97.7%. The process of preventing overcharging is as follows, the end voltage of a lead storage battery is detected, when the end voltage reaches a certain value, the du/dt detection of the end voltage of the storage battery is carried out, data is recorded every other one minute, the mean square deviation value (delta) of the data within two hours is calculated, if delta is less than 0.16, then the storage battery du/dt is considered as unchanged for two hours, and the storage battery is considered as full. Moreover, a longest charging time can be set, thus the problem that some batteries can not be stopped from being charged for a long time due to faults can be prevented, and the cutting off is controlled by an electronic switch.
