| Abstract: | After comparing the AC inserting method with the DC discharging method,this paper presents an instrument for testing the impedance of battery in service based on AC inserting method. Introduces the principle in detail and provides the practical circuit for testing the impedance of battery by using phase lock amplifying circuit. The instrument can suppress noise and interference and simplify the design by using AD630. |
