According to the present invention, a system for managing a temperature of a battery for an electric vehicle comprises: a four-way valve having first and second inflow units and first and second outflow units wherein the first inflow unit selectively communicates with any one of the first and second outflow units, and the second inflow unit selectively communicates with the other one of the first and second outflow units; a battery supplying power for driving an electric vehicle; a chiller cooling a battery by using a coolant; a reservoir tank supplying the coolant to the chiller; a radiator cooling the heated coolant; a motor module generating a driving force of the electric vehicle; a cabin heater heating the inside of the electric vehicle; a first flow path supplying the coolant discharged through the first outflow unit to the reservoir tank; a second flow path returning the coolant passing through the battery to the second inflow unit; a third flow path supplying the coolant discharged through the second outflow unit to the radiator; a fourth flow path providing the motor module and the cabin heater with the coolant cooled by passing through the radiator; and a fifth flow path returning the coolant passing through the motor module and the cabin heater to the first inflow unit. Accordingly, the battery can be pre-heated without a separate battery-dedicated heater.
