The invention provides a battery cooling control method. The battery cooling control method comprises the steps of monitoring average power consumption and a real-time battery cell temperature of a battery within a preset time; and not starting a battery cooling execution mechanism when the battery cell temperature is at a preset zone and if the average power consumption is smaller than a first preset value. The invention also provides a battery thermal management system and an electric vehicle employing the battery thermal management system. By the battery cooling control method, the energy consumption of the battery during the cooling process can be reduced.
