AC injection method is an approach which is commonly used in internal resistance online detection of battery. Extracting useful signal from the noise environment is the key technology to realize the method. This paper proposes a solution which is used to extract useful signal by FIR digital filter ,and introduces the design and simulation of filter in MATLAB and the realization of digital filter with the use of TMS 320F2812.
