Abstract

The invention relates to a later master storage battery charging system, in particular to a charging system using a pulse width modulation signal to control a storage battery. The charging system using the pulse width modulation signal to control the storage battery comprises a DC / DC convertor, a drive circuit, a charging controller, a charging sampling circuit, a charging protection circuit, an LCD display module and an RS232 communication module. The DC / DC convertor is in communication with the drive circuit, the charging sampling circuit and the charging protection circuit. The charging controller is in communication with the drive circuit, the LCD display module, the RS232 communication module and the charging sampling circuit. The drive circuit is further in communication with the charging protection circuit. A power main circuit is of a topology structure of a double-barreled flyback converter. The digital control mode based on a single chip microcomputer MSP430F2274 is adopted. The multi-mode charging control strategy is adopted in the charging system, wherein the four modes include the activated charging mode, the large-current rapid charging mode, the overcharging mode and the float charging mode.
