Summary:The invention provides a battery direct current resistance evaluation system, which comprises an impedance measuring apparatus for measuring AC resistance of a secondary battery and a DC resistance value analyzing apparatus; the DC resistance value analyzing apparatus computes a response voltage of the secondary battery based on the measuring result of the impedance measuring apparatus, a circuit constant computed by an equivalent circuit of the secondary battery, and the response voltage and the battery DC resistance measuring condition. According to the system, DC resistance of the battery can be effectively measured in a short time without using power of large volume.
