The invention discloses a method and device for determining an engine power threshold of a vehicle and a storage medium. The method comprises the steps of obtaining an actual electric quantity value of a battery of a vehicle; based on the actual electric quantity value, the electric quantity lower limit value of the battery and the electric quantity balance value of the battery, a target coefficient of the battery is determined, and the target coefficient is used for determining engine power; comparing the target coefficient with a coefficient threshold value of the battery to obtain a first comparison result; determining engine power based on the first comparison result; based on the engine power, an engine power threshold is determined. The technical problems that engine fuel economy under large-load battery assistance, medium-low-speed engine noise and electric quantity state balance under extreme working conditions cannot be effectively balanced are solved.
