摘要： A battery inspection apparatus capable of self-diagnosing failure is provided. The battery inspection apparatus includes a contact probe, a power supply module, a power cable for providing a path for supplying the power generated by the power supply module to the contact probe, a voltage measuring module, a measuring cable configured to measure a voltage of the contact probe by the voltage measuring module, a switching module configured to selectively connect the voltage measuring module to the power cable or the measuring cable, and a control module configured to determine whether at least one of the contact probe or the power cable is abnormal based on the voltage measurement value of the voltage measuring module according to a connection state of the switching module. A verification device capable of diagnosing failure of the battery inspection apparatus is also provided.
