Monitoring Method for Abnormal Output Current of Lithium Iron Phosphate Batteries in Power Applications
In order to achieve high-precision monitoring of battery current requirements,this paper proposes a monitoring method for abnormal output current status of lithium iron phosphate batteries in power applications.Using current sen-sors,the output current signal of lithium iron phosphate batteries are collected and converted.Using extended Kalman fil-tering technology,noise reduction and normalization are achieved,thereby correcting signal errors,extracting abnormal current characteristics,and identifying abnormal states.Experimental results have shown that the undetected rate of the proposed method is within 1％.
