The invention discloses a battery electric quantity prediction method and device, a vehicle, a medium and a product, and relates to the technical field of new energy. The method comprises the steps that when it is detected that a battery assembly of the vehicle is switched into a power-on state, the initial charge state of the battery assembly is obtained; determining a confidence level of the initial state of charge; determining the charge correction and the gain value of the Luenberger observer according to the confidence level; correcting the initial charge state based on the charge correction to obtain a target charge state; and based on the target state of charge and the gain value, utilizing a Luenberger observer to predict the battery remaining capacity of the vehicle in the driving process. According to the technical scheme provided by the invention, a simple hardware structure can be realized, the convergence speed of the Luenberger observer can be accelerated, and the battery remaining capacity of the vehicle in the driving process can be accurately predicted.
