Abstract:
A method for managing temperature of a battery of an electric vehicle, the method comprising:determining whether a battery charge mode is a fast-charging mode based on state information of the battery; determining whether a value of a state of charge (SOC) is lower than a predetermined SOC value, when the battery charge mode is the fast-charging mode; detecting a temperature of the battery and comparing the detected temperature with a reference value for each stage therewith, if the value of SOC is lower than the predetermined SOC value; regulating the temperature of the battery by controlling power output of a heater in response to a result of comparing the battery temperature with the reference value for each stage; detecting a temperature of the battery and comparing a difference between the detected temperature of the battery and a predetermined value with a reference temperature for each stage, when the current SOC value is determined to be less than the reference SOC value; and regulating the temperature of the battery by driving a cooling fan in response to a result of comparing the difference between the detected temperature of the battery and the predetermined value with the reference value for each stage at a final state of charging.
