Abstract
Disclosed herein is a system for controlling the cooling or heating of a battery. The system includes a battery having a hermetic sealing structure to prevent passage of air from an exterior, a pressure sensor provided on the battery to measure internal pressure of the battery, an climate control system cooling or heating the battery, and a controller determining cooling or heating of the climate control system depending on whether the internal pressure of the battery is positive pressure or negative pressure based on a measured result of the pressure sensor, the controller controlling cooling or heating strength depending on a level of the positive pressure or negative pressure.
Claims8
A system for controlling cooling or heating of a battery, comprising:
- a battery having a hermetic sealing structure to prevent passage of air f between an interior region of the battery and an exterior region;
- a pressure sensor provided on the battery and configured to measure an internal pressure of the battery;
- a climate control system configured to cool and heat the battery;
- a controller configured to determine whether to cool or heat the battery depending on whether the internal pressure of the battery is a positive pressure or a negative pressure based on a measured result of the pressure sensor, the controller controlling a cooling or a heating strength depending of the measured positive pressure or negative pressure,
- a communicating passageway connected to an interior of the battery to an exterior of the battery;
- and
- an on-off valve provided within the communicating passageway to perform a selective on-off operation,
- wherein the controller opens the on-off valve when the positive pressure or negative pressure of the battery is exceeds a maximum value and closes the on-off valve when internal pressure and atmospheric pressure of the battery equal.
A method for controlling cooling or heating of a battery, comprising:
- measuring, a sensor, pressure of the battery sealed from an exterior;
- cooling or heating, by a climate control system, the battery when the battery is positive pressure or negative pressure;
- controlling, by a controller, cooling or heating strength supplied to the battery depending on the positive pressure or negative pressure;
- terminating cooling or heating when an internal pressure or temperature of the battery calculated from the positive pressure or negative pressure is within a stable range;
- opening an on-off valve when the positive pressure or negative pressure of the battery is greater than a maximum value;
- and
- closing the on-off valve when internal pressure and atmospheric pressure of the battery equal.
