1. A system for obtaining state information of a battery, the system comprising:
at least one first harness cable configured to obtain data indicating state information of the battery from a battery management system of the battery;
an analyzer configured to provide a driving signal for driving the battery management system;
a first junction box configured to transmit the data input through the first harness cable to the analyzer;
a second junction box connected to the battery through at least one second harness cable; and
an alternating current (AC) impedance analyzer configured to detect an AC impedance of the battery through the second junction box,
wherein the analyzer is configured to output the data received from the first junction box to the outside and the second junction box comprises a circuit configured to detect the AC impedance.
