Abstract

An apparatus and method for battery temperature control, the apparatus including a cooling plate, a first transporter selectively moving the cooling plate along a first axis, and a controller operably coupled to the first transporter and selectively outputting a control signal to the first transporter for commanding the first transporter to move the cooling plate to a first location or a second location. The cooling plate comes into contact with an outer surface of the battery by a preset maximum area at the first location, and the cooling plate comes into contact with the outer surface by an area smaller than the maximum area or is separated from the outer surface at the second location.

First claim

What is claimed is:

1. An apparatus for battery temperature control, comprising:
a cooling plate configured to come into contact with an outer surface of a battery;
a first transporter in contact with the cooling plate and configured to selectively move the cooling plate along a first axis to bring the cooling plate into contact with the outer surface of the battery or separate the cooling plate from the outer surface of the battery, wherein an entirety of the first transporter is physically separated from the battery; and
a controller operably coupled to the first transporter,
wherein the controller is configured to:
select any one of a first operation mode and a second operation mode based on a first temperature value indicating a temperature of the battery,
output a first control signal to the first transporter for commanding the first transporter to move the cooling plate to a first location in response to the first operation mode being selected, and
output a second control signal to the first transporter for commanding the first transporter to move the cooling plate to a second location in response to the second operation mode being selected,

wherein the cooling plate comes into contact with the outer surface by a preset area in response to the cooling plate being moved to the first location by the first transporter,
wherein the cooling plate comes into contact with the outer surface by an area smaller than the preset area or is separated from the outer surface in response to the cooling plate being moved to the second location by the first transporter,
wherein the first transporter includes an actuator and one of a gear or a piston, and
wherein the actuator of the first transporter moves the one of the gear or the piston to move the cooling plate.

2. The apparatus for battery temperature control according to claim 1 , wherein the cooling plate includes a phase change material.

3. The apparatus for battery temperature control according to claim 1 , wherein the outer surface of the battery includes a plurality of first protrusions protruding toward the cooling plate,
wherein the cooling plate includes a plurality of second protrusions protruding toward the outer surface, and
wherein the plurality of second protrusions is disposed between the plurality of first protrusions and comes into contact with the plurality of first protrusions in response to the cooling plate being moved to the first location.

4. The apparatus for battery temperature control according to claim 1 , wherein the controller is configured to select the first operation mode in response to the first temperature value being equal to or larger than a first threshold.

5. The apparatus for battery temperature control according to claim 1 , wherein the controller is configured to select any one of the first operation mode and the second operation mode further based on a second temperature value indicating a temperature of the cooling plate.

6. The apparatus for battery temperature control according to claim 5 , wherein the controller is configured to select the first operation mode in response to the first temperature value being larger than the second temperature value and a difference between the first temperature value and the second temperature value being equal to or larger than a second threshold.

7. The apparatus for battery temperature control according to claim 6 , wherein the controller is configured to select the second operation mode (i) in response to the first temperature value being equal to or less than the second temperature value, or (ii) in response to the first temperature value being larger than the second temperature value and a difference between the first temperature value and the second temperature value being less than the second threshold.

8. The apparatus for battery temperature control according to claim 7 , wherein the controller is configured to calculate a transport distance based on the first temperature value and the second temperature value in response to the second operation mode being selected, and
wherein the transport distance indicates a distance between the first location and the second location.

9. The apparatus for battery temperature control according to claim 8 , wherein the transport distance is proportional to a difference between the first temperature value and the second temperature value.

10. The apparatus for battery temperature control according to claim 5 , further comprising:
a second transporter configured to selectively move the cooling plate along a second axis that is different from the first axis.

11. The A battery system comprising the apparatus for battery, temperature control according to claim 1 .

12. An apparatus for battery temperature control, comprising:
a cooling plate configured to come into contact with an outer surface of a battery;
a first transporter configured to selectively move the cooling plate along a first axis to bring the cooling plate into contact with the outer surface of the battery or separate the cooling plate from the outer surface of the battery; and
a controller operably coupled to the first transporter,
wherein the controller is configured to:
select any one of a first operation mode and a second operation mode based on a first temperature value indicating a temperature of the battery,
output a first control signal to the first transporter for commanding the first transporter to move the cooling plate to a first location in response to the first operation mode being selected, and
output a second control signal to the first transporter for commanding the first transporter to move the cooling plate to a second location in response to the second operation mode being selected,

wherein the cooling plate comes into contact with the outer surface by a preset area in response to the cooling; plate being moved to the first location by the first transporter,
wherein the cooling plate comes into contact with the outer surface by an area smaller than the preset area or is separated from the outer surface in response to the cooling plate being moved to the second location by the first transporter,
wherein the controller is configured to select any one of the first operation mode and the second operation mode further based on a second temperature value indicating a temperature of the cooling plate,
