Disclosed herein is a device for controlling the temperature of batteries for electric vehicles. The device includes a thermoelectric semiconductor unit, a thermoelectric semiconductor unit, a temperature sensor, and a battery controller. The thermoelectric semiconductor unit is configured such that a portion thereof is exposed in a battery tray. The thermoelectric semiconductor unit controller causes the thermoelectric semiconductor unit to radiate heat, and causes the thermoelectric semiconductor unit to absorb heat. The temperature sensor detects and outputs the temperature of the battery tray. The battery controller outputs the heat radiating control signal to the thermoelectric semiconductor unit controller when the temperature detected by the temperature sensor is lower than a predetermined value, and outputting the heat absorbing control signal to the thermoelectric semiconductor unit controller when the temperature detected by the temperature is equal to or higher than the predetermined value.
