The present invention relates to a battery thermal management control apparatus for an electric vehicle using a variable flow rate and a control method therefor, comprising: a heating medium line which is formed in a closed-loop form and allows a heating medium to flow through a battery; a pump disposed in the heating medium line to flow the heating medium; a heating unit disposed on the heating medium line to increase a temperature of the heating medium; and a controller for operating a pump by receiving the temperature of the battery. The controller controls the pump according to the temperature of the battery to vary a flow rate of the heating medium. The present invention provides the battery thermal management control apparatus for the electric vehicle using the variable flow rate which provides an optimal flow rate of the heating medium heated according to the temperature of the battery of the electric vehicle, and the method therefor.
