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
