The invention discloses a vehicle power battery electric quantity control method and device and a computer program product, and the method comprises the steps: calculating a power battery electric quantity demand value of a current vehicle according to the pre-sales maximum parking time of the current vehicle, the whole vehicle quiescent current test data, and the power consumption data of a high-voltage system during the operation of an automatic charging function; when the current vehicle is in a storage and transportation mode and the power battery electric quantity is lower than the power battery electric quantity demand value, a power battery charging request is sent; and starting an engine to charge a power battery according to the power battery charging request. By accurately calculating the electric quantity demand of the power battery, it is ensured that the power battery can maintain the necessary electric quantity in the key period, the problem that the vehicle cannot be started due to insufficient electric quantity is avoided, and the battery maintenance efficiency and safety of the hybrid vehicle in the long-time parking period are remarkably improved.
