<p>There are disclosed a method and apparatus for diagnosing faults in a battery pack and a power relay assembly using the same. An apparatus for diagnosing faults in a battery pack including a plurality of cells includes a pack voltage measurement unit for measuring a voltage of the battery pack, a cell voltage measurement unit for measuring a plurality of cell voltage for the plurality of cells, and a controller for determining whether there are faults in the battery pack based on the voltage of the battery pack and the plurality of cell voltages. A battery pack and a load connected to the battery pack can be protected by diagnosing whether there are faults in the battery.</p> |
