Title:
CHARGE CAPACITY CALCULATION DEVICE AND METHOD FOR ENERGY STORAGE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/164263
Kind Code:
A1
Abstract:
A method for calculating the charge capacity of an energy storage system, according to one embodiment of the present invention, comprises: 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 the voltage of the energy storage system while the predetermined current having a constant value is applied to the energy storage system; a second voltage measurement step of measuring the voltage of the energy storage system after cutting off the predetermined current having a constant value, which has been applied to the energy storage system; and a resistance (R) and capacitance (C) calculation step of calculating the resistance (R) and the capacitance (C) of the energy storage system on the basis of 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 a constant value.
