Abstract

A method for calculating a short-circuit current of a battery. includes: obtaining an integral state of charge and a current state of charge of the battery; calculating a first difference based on the integral state of charge and the current state of charge; calculating the short-circuit current of the battery based on the first difference; obtaining a first real state of charge and a second real state of charge; updating the first real state of charge and the second real state of charge based on a temperature-impedance table and the short-circuit current of the battery; calculating a second difference based on the updated first real state of charge and the updated second real state of charge; and updating the short-circuit current of the battery based on the second difference.
