Abstract
Provided is a method of calculating a resistance and a capacitance of an energy storage system, including a current application step of applying a predetermined current having a constant value to the energy storage system; a first voltage measurement step of measuring a voltage of the energy storage system while the predetermined current is applied to the energy storage system; a second voltage measurement step of measuring a voltage of the energy storage system after breaking the predetermined current applied to the energy storage system; and a step of calculating a resistance (R) and a capacitance (C) of the energy storage system based on the voltage of the energy storage system measured in the first voltage measurement step, the voltage of the energy storage system measured in the second voltage measurement step, and the predetermined current having the constant value.
