1. A battery pack simulation device connected to a battery management unit to check a function of the battery management unit, the device comprising:
an input unit configured to receive initial data of a virtual battery pack including a voltage value, a current value, and an initial impedance value of the virtual battery pack;
an output value generation unit configured to generate virtual battery pack measurement data including an impedance value and a voltage value varying based on the received voltage value, current value, and initial impedance value;
a transmission unit configured to transmit at least a part of the generated virtual battery pack measurement data to the battery management unit; and
a monitoring unit configured to receive predetermined information related to the function of the battery management unit, from the battery management unit, and monitor whether the battery management unit operates normally based on the predetermined information,
wherein the output value generation unit comprises an impedance value variation unit configured to output a variable impedance value obtained by changing the received initial impedance value by a predetermined value at a predetermined time interval.
