SHORT-CIRCUIT CURRENT PREDICTION DEVICE AND METHOD

A short-circuit current prediction method includes deriving an internal equivalent circuit of a battery that reflects a short circuit condition in a direct current (DC) circuit, derive a first equivalent circuit in consideration of electrical characteristics of the battery, deriving a second equivalent circuit in consideration of electrical characteristics of a fuse, obtain a short-circuit current prediction model by reflecting the first equivalent circuit and the second equivalent circuit based on the internal equivalent circuit, and predict the short-circuit current according to a battery voltage using the short-circuit current prediction model. Thus, high-precision short-circuit current prediction is possible in units of battery modules, racks, and systems.
