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.

Description

technical field [0001] The present invention relates to the charging system of the total accumulator in the future, in particular to a solar accumulator charging system controlled by a pulse width modulation signal (PWM). Background technique [0002] With the increasing shortage of energy and the aggravation of environmental pollution, green industries such as photovoltaic power generation and electric vehicles have become the focus of attention. In these fields, lead-acid battery has been widely used as a reusable energy storage device, but charging has always been a key issue affecting its service life. Therefore, this method is dedicated to research and design a fast, safe and intelligent battery charging system Contents of the invention [0003] The technical effects of the present invention can overcome the above-mentioned defects, and provide a battery charging system controlled by a pulse width modulation signal, which can realize fast, safe and intelligent chargi...
