BATTERY DIAGNOSIS SYSTEM, VEHICLE EQUIPPED WITH THE SAME, AND BATTERY DIAGNOSIS METHOD

A battery diagnosis system includes a sensor that measures a voltage of a secondary battery, and a processor configured to diagnose whether the secondary battery is a genuine product based on a voltage curve indicating a time change of a voltage measured by the sensor during a diagnosis target period. The diagnosis target period includes both a charging and discharging period and a charging and discharging pause period.
