BATTERY TEMPERATURE CONTROLLER FOR ELECTRIC VEHICLE USING THERMOELECTRIC SEMICONDUCTOR
First Claim
1. A device for controlling a temperature of batteries for electric vehicles, comprising:
- a thermoelectric semiconductor unit configured such that a portion thereof is exposed in a battery tray, thus radiating heat into a battery tray when input current flows in a first direction and absorbing heat inside the battery tray when the input current flows in a second direction;
a thermoelectric semiconductor unit controller for causing the thermoelectric semiconductor unit to radiate heat by supplying the current, which flows in the first direction, to the thermoelectric semiconductor unit when a heat radiating control signal is input thereto, and causing the thermoelectric semiconductor unit to absorb heat by supplying the current, which flows in the second direction, to the thermoelectric semiconductor unit when a heat absorbing control signal is input thereto;
a temperature sensor for detecting and outputting a temperature of the battery tray; and
a battery controller for outputting the heat radiating control signal to the thermoelectric semiconductor unit controller when a 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.

Abstract
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.
