VEHICLE CONTROL DEVICE AND METHOD THEREOF

A vehicle control device and a method thereof are provided. The vehicle control device includes a plurality of battery cells, a processor, and a memory. The processor is configured to identify first time constants of each of the battery cells, when a vehicle maintains a no-load state during a specified time, obtains a comparison dataset indicating a difference between an average value for the first time constants and each of the first time constants, and diagnoses a state of each of the battery cells, using the comparison dataset.
