摘要
现在锂电池的内阻测量大部分采用交流压降内阻测量法,该方法虽然可以适用于很多电池内阻的测量,但是其精度和抗干扰性都不如直流放电内阻法并且测量电路也比直流放电内阻法的电路复杂。但是在使用直流放电法测量锂电池内阻时也有不足,容易产生极化内阻。利用短脉冲电流测量锂电池的内阻保留直流放电法的优点又可以避免极化内阻的产生。
Most of the internal resistance measurement of lithium battery adopts AC voltage drop internal resistance measurement method.Although this method can be applied to many internal resistance measurement of battery,but its accuracy and anti-interference are not as DC discharge resistance method and measurement circuit But also than the DC discharge resistance method of the circuit is complex.However,the use of DC discharge method to measure lithium battery resistance is also inadequate,prone to polarization resistance.The use of short pulse current measurement of the internal resistance of lithium batteries to retain the advantages of DC discharge method can avoid the generation of polarized resistance.
