A charging and discharging switching unit having a charging and discharging switch and a fuse is installed on a charging and discharging path between a battery cell and a pack terminal. The apparatus includes a first diagnosing path a second diagnosing path, a third diagnosing path, an integrated diagnosing path having a diagnosis switching unit and a diagnosis resistor, a voltage measuring unit, and a control unit configured to turn on and off the diagnosis switching unit and determine whether the charging and discharging switching unit is operating abnormally based on the diagnosis voltage measured by the voltage measuring unit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Battery pack diagnosis apparatus","description":"An apparatus and method for diagnosing whether a charging and discharging switching element provided on a charging and discharging path of a battery pack operates normally.
