The invention discloses a preheating control method of a power battery. The method relates to the field of intelligent automobiles and comprises the steps that first temperature data of a power battery, the power of a water heating heater and the predicted automobile using time are obtained, the first temperature data are the internal and external temperatures of the power battery, and the predicted automobile using time is the predicted working time of the power battery; based on the first temperature data, the water heating heater power and the predicted vehicle using time, the target preheating starting time is determined; and in response to the arrival of the target preheating starting moment, a water heating heater and an electric water pump are controlled to preheat the power battery based on the predicted vehicle using moment, the water heating heater is used for heating water in a pipeline connected with the power battery, and the electric water pump is used for transferring hot water to the power battery. The technical problem that when the power battery is preheated, the resource utilization rate is low is solved.
