A method for obtaining a battery state of charge, said method comprising: according to a pre-constructed battery model, calculating a functional relationship between the open-circuit voltage of a battery and the state of charge and the temperature (S10), and obtaining an internal characteristic parameter of the battery (S20); according to the functional relationship and the internal characteristic parameter of the battery, performing a dual-Kalman calculation to obtain the state of charge of the battery (S30). |
