A battery control device of a battery system including at least one battery, includes: a storage device to store a safety limit range for a parameter related to a state of the at least one battery, and a threshold setting value for the parameter; a communication device to communicate with a test device; and a controller to: operate a protection function of the battery system based on the threshold setting value; change the threshold setting value based on a change value received from the test device if a change of the threshold setting value is requested; and limit the change of the threshold setting value if the change value is out of the safety limit range.
