The invention discloses a power battery temperature control method and system, a terminal and a storage medium, and belongs to the technical field of power battery control. According to the current vehicle speed and the related data of the power battery, determining the rotating speed of an air blower and the air inlet temperature of the battery, which are required by the current battery system, by taking the optimal working temperature of a battery cell of the battery system and in-vehicle noise limitation as targets; and sending an instruction to a corresponding device according to the rotating speed of the air blower and the air inlet temperature of the battery required by the current battery system. According to the utility model, the battery works in the optimal temperature interval by using the current cold and heat quantity of the vehicle air conditioning system, the vehicle speed, the rotating speed of the battery blower, the air inlet temperature of the battery, the current temperature of the battery and the charging and discharging power of the battery in the first X seconds, and the air inlet temperature of the battery and the rotating speed of the battery blower, thereby comprehensively protecting the use performance and service life of the battery; meanwhile, the noise in the vehicle is reduced, and the influence on the comfort of a driver and passengers is reduced.
