The embodiment of the invention is suitable for the technical field of automobiles, and provides a battery state determination method and device, a vehicle-mounted terminal and a vehicle. The method comprises the steps that working data of a brake battery corresponding to a state judgment scene is obtained; the state judgment scene comprises an electric quantity judgment scene; the working data corresponding to the electric quantity judgment scene comprises a capacitance value of the brake battery and the residual electric quantity of the brake battery; and determining the battery state of the brake battery based on the working data and a judgment condition corresponding to the state judgment scene. According to the method provided by the embodiment of the invention, calculation can be performed by combining the capacitance value and the residual electric quantity of the brake battery in an electric quantity judgment scene of the vehicle-mounted terminal, so that the determination accuracy of the battery state is improved.
