AbstractLead-acid batteries are always accompanied by the deposition and dissolution of lead sulfate during use. In the long-term use process or improper operation, a large amount of lead sulfate will be deposited on the surface of the plate, affecting its life and efficiency. Pulse current charging is a common charging method now, which can effectively alleviate the sulfation problem of the battery. This paper establishes a battery electrochemical model, and simulates and analyzes the changes in the internal structure during the pulse charging process of the battery to effectively repair the charging curve of the sulfided lead-acid battery, and designs the charging power supply circuit topology. After simulation experimental analysis, the results show that the charging method proposed in this paper can effectively remove lead sulfate from the surface of the battery plate and achieve an activation effect.
