The invention provides a battery thermal management control method and device, electronic equipment and a storage medium, and relates to the technical field of vehicles. The method comprises the following steps: in response to a vehicle in a charging state, acquiring external environmental noise of the vehicle; determining a rotating speed limit value of the cooling fan based on the decibel value of the environmental noise and the decibel values of the cooling fan at different working rotating speeds; obtaining heat dissipating capacity required in the charging process of the vehicle battery; and after the measured temperature of the vehicle battery reaches the set temperature interval, the rotating speed of the cooling fan is controlled to be lower than the rotating speed limit value based on the heat dissipating capacity. After the measured temperature of the vehicle battery reaches the set temperature interval, the cooling fan can be controlled to operate in advance according to the heat possibly generated in the whole charging process, the rotating speed peak value of the cooling fan is controlled under the condition that the heat dissipation requirement of the vehicle battery is met, the rotating speed is prevented from being high, and then the problem that noise is large in the charging process is solved.

    本公开提供了一种电池热管理控制方法、装置、电子设备及存储介质,涉及车辆技术领域。该方案为:响应于车辆处于充电状态,获取车辆外界的环境噪声;基于环境噪声的分贝值和散热风扇在不同工作转速下的分贝值,确定散热风扇的转速限值;获取车辆电池充电过程中所需的散热量;在车辆电池的测量温度达到设定温度区间后,基于散热量,控制散热风扇的转速低于转速限值。本公开中可以在车辆电池的测量温度达到设定温度区间后,提前根据整个充电过程可能产生的热量,控制散热风扇运转,在保证车辆电池散热需求的情况下,控制散热风扇的转速峰值,避免转速较高,进而解决充电过程中噪音大的问题。
