Summary:
The quality of the lithium battery charging circuit is not only related to the life and efficiency of the lithium battery, but also related to the safety of the lithium battery. According to the characteristics of lithium battery, the charging circuit and protection circuit of lithium iron phosphate battery are designed. The correctness of the charging circuit designed in this paper is verified by experiments. At the end of the article, the experimental platform is built according to the designed charging circuit, and the voltage of the lithium battery under the state of charge is collected by the acquisition circuit of the single-chip microcomputer, and the curve is drawn.
