Lithium battery and charging/discharging state monitoring method thereof

Abstract

The invention relates to a lithium battery. The lithium battery comprises a shell, a charging circuit, a lithium battery body and a chip, wherein the charging circuit, the lithium battery body and thechip are arranged in the shell; the shell is provided with a positive tab and a negative tab which are connected with the charging circuit; the chip is connected with the charging circuit and a USB interface arranged on the shell; the charging circuit is connected with the lithium battery body; and the lithium battery body is subjected to charging and discharging through the charging circuit. Themethod comprises a charging management step, a state monitoring step and a data processing step. With the lithium battery and the charging/discharging state monitoring method thereof of the invention, the temperature of an environment where the battery is located, the internal temperature of the battery, the magnitude of the charging and discharging current of the battery, the charging and discharging working time of the battery and the charging and discharging electric quantities of the battery in each charging and discharging process are accurately recorded; and the actual remaining batterycapacity, instant state of health and actual remaining battery service life of the lithium battery can be accurately and reliably judged. The lithium battery is of great significance for improving the use and efficiency of lithium batteries, improving the use convenience of the lithium battery and promoting the development of the lithium battery market.
