Abstract: In allusion to the complexity of method of battery impedance measurement, a method was presented to tell how to achieve high accuracy of phase measurement by accurate ADC,to measure the battery impedance simply based on phase detector processing technology,which greatly simplifies the work load. This paper introduced the work principle and the process of implementation of this method.Application results show that the method has high practice value and popularization sense because of its simplicity and high precision.
