Unlike small mobile devices, middle- or large-sized battery modules such as automobiles are used in which a large number of battery cells are connected to each other in order to meet the requirement of high output capacity.

On the other hand, when the battery constituting the battery module is not in an appropriate temperature range, the charge / discharge power and efficiency of the battery are drastically reduced based on a specific temperature. When the temperature of the battery is low and it is not possible to supply sufficient charge / discharge power, there is a problem that the function of the vehicle using such a battery as a power source is also greatly restricted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following description of the present invention, a detailed description of known arts which may unnecessarily obscure the gist of the present invention will be omitted.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram illustrating a general outline and operation principle of a battery pack heating device 11 for a hybrid vehicle according to an embodiment of the present invention. Referring to FIG.

Basically, the battery pack heating apparatus 11 according to the present embodiment uses the exhaust pipe 13 for passing the exhaust gas discharged from the engine 33 installed in the hybrid vehicle 31 (FIG. 2) as a high-temperature heat source , And the heat of the exhaust pipe (13) is transferred to the battery pack (19) to heat the battery pack (19).

As shown in the drawing, the heating apparatus 11 according to the present embodiment includes a heat absorbing amount adjusting unit 15, 45 which is disposed apart from the exhaust pipe 13 and receives radiation heat once generated in the exhaust pipe 13, A heat transfer unit 17 for transferring the heat received from the regulating unit 15 to the battery pack 19 through the heat or heat quantity regulating unit 45 and a temperature sensor for sensing the current temperature of the battery pack 19. [ And a controller 23 for operating the heat quantity adjusting units 15 and 45 based on the temperature information received from the temperature sensor 21. [

The heat absorbing amount regulating portions (15, 45) are provided on the side of the exhaust pipe (13) and receive radiant heat of the exhaust pipe (13). In the present embodiment, the hydrothermal regulator 15, 45 includes two types. The first type is shown in FIGS. 4 and 5, and the second type is shown in FIGS. 6 to 8. FIG.

The hydrothermal regulator (15, 45) is driven by the controller (23), and its detailed structure and operation will be described later.

The controller 23 compares the current temperature of the battery pack 19 received from the temperature sensor 21 with the reference temperature stored in the battery pack 19 (desired temperature of the battery pack) It is judged whether the regulating portions 15 and 45 and the heat transfer portion 17 should be operated.

When the current temperature of the battery pack 19 is lower than the reference temperature, the heat receiving plate 15a of the heat absorbing amount adjusting unit 15 is moved closer to the exhaust pipe 13 and the heat receiving plate 15a (See FIG. 3), or the variable vane (45c in FIG. 7) is moved in the direction of the arrow y in FIG. 7 so as to actively receive the heat of the exhaust pipe, block the arrangement Direction to increase the amount of heat passing through the frame.

Conversely, when the present temperature of the battery pack 19 is not lower than the reference temperature, the heat plate 15a is moved away from the exhaust pipe 13, the blower 17c is stopped, the arrangement hole 39a is completely opened, The variable vane 45c is closed so that the heat does not go to the heat pipe 17a.

FIG. 2 is a view showing a schematic configuration of a hybrid vehicle 31 provided with the battery pack heating device 11 shown in FIG.

Referring to the drawings, the hybrid vehicle 31 according to the present embodiment includes an engine 33 that burns fuel to obtain a driving force, an exhaust pipe 13 that exhausts exhaust gas generated from the engine 33, A motor 37 used as a driving source together with the engine 33, a battery pack 19 for supplying power to the motor 37, and a temperature sensor 21 for sensing the temperature of the battery pack 19 (15,45) arranged to be spaced apart from the exhaust pipe (13) and to receive heat generated in the exhaust pipe (13), and a battery pack (17) receiving the radiation heat of the exhaust pipe A heat transfer unit 17 for transferring the heat, and a control unit 23.

The control unit 23 controls the hydrothermal regulators 15 and 45 and the heat transfer unit 17 on the basis of the temperature information received from the temperature sensor 21 and is connected to an electronic control unit Can be integrated.

The engine 33 is a typical one that generates rotational torque using gasoline, diesel, or gas as fuel. The motor 37 receives power from the battery pack 19 and generates driving force for driving the vehicle.

The exhaust pipe 13 is a general exhaust pipe that passes exhaust gas generated by the combustion of fuel in the engine 33 and discharges pollutants into the air in a state of removing the pollutants, and is disposed at the bottom of the vehicle. For reference, the temperature of the exhaust pipe 13 may be increased to 600 ° C.

3 is a block diagram showing the structure of a part of the heat quantity adjusting section 15 and the heat transfer section 17 shown in FIG.

Basically, the heat transfer portion 17 serves to increase the temperature of the battery pack 19 by moving the heat transferred from the exhaust pipe 13 to the battery pack 19. [

As shown in the drawing, the heat transfer portion 17 according to the present embodiment includes a heat pipe 17a extending in the longitudinal direction and moving heat transferred directly or indirectly from the exhaust pipe 13, A heat sink 17b provided at an end of the battery pack 19 and disposed close to the battery pack 19; a blower 17c disposed opposite the battery pack 19 with the heat sink 17b interposed therebetween; A conductor 43 for directly transferring the heat transferred through the heat pipe 17a to the battery pack 19 in a state of being closely contacted to the battery pack 19 and the battery pack 19 and the heat sink 17b and the blower 17c (Not shown).

First, the heat pipe 17a is extended to the inside of the heating duct 39 with one end of the heat pipe 17a being in contact with the turning shaft 15c of the heat-receiving plate 15a (as shown in Fig. 4) The heat of the heat exchanger 15a is transferred to the heat sink 17b or the heat of the heat exchanger 15 is received by the heat receiving portion 45 as shown in FIG. The type, length, number of applications, etc. of the heat pipe 17a may vary depending on the case.

The heat sink 17b is arranged close to the side of the battery pack 19 and serves to discharge the heat transmitted through the heat pipe 17a to the surroundings. The heat emitted from the heat sink 17b is obtained from the exhaust pipe 13 and is pushed by the blower 17c to the battery pack 19 to heat the battery pack 19. [ The heat sink 17b may be disposed as close to the battery pack 19 as possible.

In addition, the shape and the number of the heat sink 17b may vary. A plurality of heat sinks 17b may be placed close to the point of interest of the battery pack 19 and each heat sink 17b may be thermally contacted with the heat receiving plate 15a by applying heat pipes 17a There is also.

The blower 17c pushes the heat coming from the heat sink 17b to the battery pack 19 and moves it. The blower 17c is a conventional blower having a fan and a motor for driving the fan.

The conductor 43 is a conductive member directly contacting the battery pack 19 and transfers the heat of the heat pipe 17a to the battery pack 19. [

The heating duct 39 serves to guide the air discharged from the blower 17c to the battery pack 39 without being scattered around and to protect the heat pipe 17a and the heat sink 17b .

The heating duct 39 is accommodated up to the battery pack 19 so that the battery pack 19 is heated by the heating duct 39 in consideration of cooling of the battery pack. It can be installed outside. Even so, the downstream end of the heating duct 39 should be close to the battery pack 19.

Further, the heating duct 39 is provided with an arranging hole 39a. The array member 39a is a passage for discharging heat, which may be discharged from the heat sink 17b, to the outside of the heating duct 17 when, for example, the heating of the battery pack 19 is not required. In fact, when there is no need to heat the battery pack 19, heat is not transmitted from the heat sink 17b by the action of the control unit 23. [

The array member 39a is opened and closed by a sliding door 39b. The sliding door 39b is a door slidably installed on the upper portion of the heating duct 39 and functions to open and close the arrangement hole 39a. The sliding door 39b blocks the arrangement opening 39a when the battery pack 19 is heated and opens the arrangement opening 39a when it is not necessary to heat the battery pack 19. [

For opening and closing the sliding door 39b, a rack gear 39c is fixed to the upper surface of the sliding door 39b, and a driving gear 41b meshes with the rack gear 39c. The driving gear 41b is rotated by the door opening / closing motor 41 to reciprocate the rack gear 39c horizontally. It goes without saying that the operation of the door opening / closing motor 41 is also controlled by the control unit 23.

FIG. 4 is a perspective view showing a part of the heat quantity adjusting unit 15, and FIG. 5 is a view for explaining the operation of the heat quantity adjusting unit 15. As shown in FIG.

As shown in the drawings, the heat quantity adjusting unit 15 applied to the heating device 11 of the present embodiment is a heat exchanger plate (heat exchanger) 15 which is disposed on the side of the exhaust pipe 13 and has a pivot shaft 15c at the lower end A supporting member 15m for rotatably supporting the rotary shaft 15c and an actuator 15e for rotating the heat receiving plate 15a.

The heat receiving plate 15a is a metal plate having a predetermined thickness and is curved so as to receive radiant heat emitted from the exhaust pipe 13 more effectively. In some cases, the heat plate 15a may be formed in a completely flat shape without curving. The heat receiving plate 15a may be made of aluminum or copper plate having good thermal conductivity.

The rotating shaft 15c located at the end of the heat receiving plate 15a takes the form of a hollow pipe and accommodates therein a sliding bearing 15b and a part of the heat pipe 17a. The sliding bearing 15b slides while being interviewed on the inner circumferential surface of the rotating shaft 15c.

The sliding bearing 15b is fitted in the rotating shaft 15c with the heat pipe 17a inside and is heated by receiving the heat of the heat receiving plate 15a. The heat pipe 17a receives the heat of the heat receiving plate 15a through the sliding bearing 15b. The temperature of the sliding bearing 15b and the heat receiving plate 15a are the same.

The support member 15m supports the pivot shaft 15c so as to be rotatable in a state where it is supported at an arbitrary place inside the hybrid vehicle 31. [ As long as such a function can be performed, the supporting method of the heat plate 15a can be changed as much as possible.

On the other hand, an adjusting arm 15d is fixed to the lower side of the rotating shaft 15c. The adjusting arm 15d is a portion extending in a direction perpendicular to the longitudinal direction of the rotating shaft 15c, and the actuator 15e is linked to the extending end.

The actuator 15e is a position changing unit for rotating the hydrothermal plate 15a and adjusting the average distance and angle of the heat receiving plate 15a with respect to the exhaust pipe 13, A cylinder 15f connected to the cylinder 15f by a support pin 15n and an operating rod 15g which moves in the longitudinal direction with a part thereof inserted into the cylinder 15f, And a holder 15k for connecting the adjustment arm 15d.

When the actuator 15e operates according to the control signal of the control unit 23, the heat receiving plate 15a rotates and the relative position of the heat receiving plate 15a with respect to the exhaust pipe 13 is changed. That is, the heat receiving plate 15a can approach the exhaust pipe 13 and can be moved away from the exhaust pipe 13.

Particularly, when the heat plate 15a completely laps in the direction of the arrow z, the radiant heat of the exhaust pipe 13 hardly reaches the heat plate 15a, and there is no heat transfer through the heat pipe 17a.

FIG. 6 is a perspective view showing another example of the heat quantity adjusting unit and the heat pipe shown in FIG. 3, and FIG. 7 is a perspective view of the heat quantity adjusting unit 45 of FIG. 8 is a view for explaining the operating characteristics of the hydrothermal regulator 45. As shown in FIG.

A heat storage amount control unit 45 is disposed on the side of the exhaust pipe 13 and a heat pipe 17a is provided on the opposite side of the exhaust pipe 13 with the heat quantity adjustment unit 45 therebetween. ) Is located.

The heat pipe 17a is in the form of a plate as a flat plate type and receives radiant heat of the exhaust pipe 13 when the variable vane 45c is opened as shown in Fig. It is needless to say that a plurality of round-bar-shaped types can be applied without applying the flat-plate type.

The heat absorbing amount adjusting unit 45 is provided between the heat pipe 17a and the exhaust pipe 13 and regulates the amount of heat radiated from the exhaust pipe 13 to the heat pipe 17a.

The hydrothermal adjustment unit 45 has a frame 45a which is shaped like a rectangular frame and is fixedly supported on an appropriate portion of the vehicle and a plurality of variable vanes (not shown) provided rotatably in an inner region of the frame 45a A vane motor 45b for rotating the variable vane 45c by angularly moving the rotary shaft 45f of the variable vane 45c on one side of the variable vane 45c, a link member 45p for interconnecting the variable vane 45c, .

Each of the variable vanes 45c is made of a heat-resistant metal and has a pivot shaft 45f at a central axis portion in the width direction of both ends. The rotary shaft 45f is fitted in a support groove 45e formed in the frame 45a and rotates the variable vane 45c in the direction of arrow y or the opposite direction.

The drive shaft hole 45d formed at one end of the upper side of the frame 45a is a passage through which the drive shaft 45k of the vane motor 45b passes.

On the other hand, the link member 45p is a steel material extending in the longitudinal direction, and the bearings 45n are supported by the fixed shaft 45m, which is erected on the upper end side of each variable vane 45c. The shorter the length of the fixed shaft 45m is, the better.

As described above, since the linear link member 45p is supported by the bearing 45n, for example, when the link member 45p linearly moves in the direction of arrow z, the fixed shaft 45m can follow the link member 45p .

When the drive shaft 45k of the vane motor 45b is rotated in the direction of the arrow f in the heat quantity adjustment portion 45 having the above-described configuration, the variable vane 45c fixed to the drive shaft 45k is rotated in the same direction At the same time, the link member 45p is pulled in the direction of the arrow z. As the link member 45p moves in the direction of arrow z, the other variable vane 45c also rotates in the direction of the arrow y and opens as shown in Fig.

The angle of rotation of the variable vane 45c is between 0 and 90 degrees. When the rotation angle is 0 degree, the variable vane 45c is blocked, and when the rotation angle is 90 degrees, it is completely opened, and the radiation heat of the exhaust pipe 13 is transmitted to the heat pipe 17a at the maximum.

FIG. 9 is a flowchart showing a battery pack heating method for a hybrid vehicle according to an embodiment of the present invention.

The battery pack heating method according to the present embodiment is a method for maintaining the battery pack 19 in the hybrid vehicle 31 within a desired temperature range.

The temperature sensing step 100 senses the current temperature of the battery pack 19 using the temperature sensor 21 and the temperature of the battery pack 19 obtained through the temperature sensing step 100 to a set reference temperature 45 and the heat transfer unit 17 when the temperature of the battery pack 19 is lower than the reference temperature through the temperature comparison step 102. The heat storage unit 15, And conveys the heat of the exhaust pipe 13 to the battery pack 19. The heating step comprises a hydrothermal regulator operating step (104) and a heating step (106).

The temperature comparison step 102 is a process in which the control unit 23 compares the reference temperature stored in the control unit 23 with the current temperature. And determines whether to perform the heat quantity adjuster operating step 104 and the heat transfer step 106 through the temperature comparing step (102).

The operation of the hydrothermal adjustment unit 104 may be performed by adjusting the relative position of the heat receiving plate 15a with respect to the exhaust pipe 13 or by adjusting the turning angle of the variable vane 45c to the heat pipe 17a And the heat transfer step 106 is a process of transferring the heat of the heat sink 17b to the battery pack 19 through the blower 17c.

The temperature sensor 21 continuously checks the temperature of the battery pack 19 and sends it to the control unit 23 even during the heating step 106. When the temperature of the battery pack 19 received through the temperature sensor 21 reaches a desired temperature range, the control unit 23 separates the heat receiving plate 15a from the exhaust pipe 13, The variable vane 45c is closed to prevent the heat from passing therethrough.

As a result, the battery pack 19 is always kept within a desired temperature range by the continuous operation of the temperature sensor 21 and the control unit 23 as described above.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not to be limited to the details thereof and that those skilled in the art, It is apparent that the present invention can be modified or improved by the present invention.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
