A system of testing electricity flow of a battery manages registration, modification, deletion, and display of a set value, a measured value, and a diagnostic value for each test item for the battery and matches the set value for each test item registered by the test item manager with a type of the battery and stores the set value. The system also identifies a phase difference between an input frequency input to the battery and an output frequency corresponding to the input frequency to determine a high-frequency resonant frequency and then calculates an AC impedance corresponding to the determined high-frequency resonant frequency and compares the calculated AC impedance with an electricity flow upper limit to diagnose that the electricity flow is normal when the calculated AC impedance is lower than the electricity flow upper limit and diagnose that the electricity flow is abnormal when the calculated AC impedance is higher.

Battery electric flow test system and method

A system for obtaining state information of a battery may be disclosed. The system includes: at least one first harness cable for obtaining, on the basis of a CAN protocol, data indicating state information of the battery from a battery management system of the battery; an analyzer for providing a driving signal for driving the battery management system; and a first junction box for transmitting the data input through the first harness cable to the analyzer, wherein the analyzer may be configured to output the data received from the first junction box to the outside.
