The invention provides a cooling method and device for a vehicle power battery, electronic equipment and a vehicle, and relates to the technical field of vehicle control, the method comprises the following steps: in response to a power battery cooling demand, carrying out cooling pretreatment on a driving motor cooling loop; when the temperature of the driving motor cooling loop is lower than a first preset temperature threshold value and the temperature difference between the driving motor cooling loop and the power battery is larger than a preset temperature difference threshold value, the power battery cooling loop is controlled to be communicated with the driving motor cooling loop; and controlling the cooling liquid in the power battery cooling loop to circularly cool through a low-temperature radiator in the driving motor cooling loop. According to the invention, by means of an energy-saving cooling means, a very common power battery heating scene and a relatively low cooling requirement for the power battery can be met, and a driving system loop and a heat management loop of the power battery can reach a balanced state by consuming very little energy; and the power battery is ensured to be stably in a temperature interval with excellent charge-discharge performance for a long time.
