The embodiment of the invention provides a battery state-of-charge value determination method and device, a medium and a vehicle, and the method comprises the steps: obtaining at least one working state parameter sequence of a target battery at a first moment, the working state parameter sequence being used for describing the change condition of the working state parameter of the target battery along with time, the working state parameter sequence comprises a working state parameter value of the target battery at the first moment; determining target characteristic data of the target battery based on the at least one working state parameter sequence; and inputting the target feature data into a state-of-charge value prediction model, so that the state-of-charge value prediction model outputs a target state-of-charge value of the target battery at the first moment, the state-of-charge value prediction model being obtained by pre-training based on a bidirectional long-short term memory network. According to the technical scheme, the state-of-charge value of the battery is predicted based on the bidirectional long-short-term memory network, and the accurate state-of-charge value can be predicted under the condition of few computing resources.
