Abstract
Description
- The present application claims priority to Korean Patent Application No. 10-2020-0162439, filed Nov. 27, 2020, the entire contents of which is incorporated herein for all purposes by this reference.
- The present disclosure relates to a battery unit for a vehicle and an underbody of the vehicle including the same, and more particularly, to a battery unit having a structure to be installed under a center floor of a vehicle and an underbody of the vehicle on which the battery unit is installed.
- An electrically driven vehicle that is driven using an electric motor, such as a hybrid vehicle, a fuel cell vehicle, or an electric vehicle, includes a high voltage battery unit that stores driving power to be provided to the electric motor. The high voltage battery unit generally includes a case that forms a sealed internal space for a battery and a plurality of battery cells, and may also include a battery management system (BMS) configured to monitor voltages, currents, temperatures, and the like of battery modules installed in the sealed internal space of the case and battery cells in the battery modules, and manage the battery based thereon.
- In addition, as a way of installing a high voltage battery module in the electrically driven vehicle, the high voltage battery unit is mounted in a trunk or a luggage space of the vehicle or mounted and fixed under a center floor of a vehicle body outside the vehicle. When the high voltage battery unit is mounted in the trunk or the luggage space of the vehicle, since the trunk or the luggage space of the vehicle is reduced, it is difficult to mount other components required for the vehicle such as spare tires, and it is also difficult to mount a third-row seat or implement a full flat seat utilizing the luggage space in a sport utility vehicle (SUV) or a multi-purpose vehicle (MPV).
- When the high voltage battery unit is mounted under the center floor of the vehicle, it is possible to maximize the utilization of the trunk or the luggage space in the vehicle, but it is difficult to secure a space for disposing a propeller shaft for transmitting power from a power train (an engine and a motor), which is mounted at the font of the vehicle, to a rear wheel. Thus, when the high voltage battery unit is installed under the center floor outside the vehicle, it is necessary to mount a separate motor for driving the rear wheel to implement an all-wheel drive (AWD) operation. Particularly, it is not possible to increase a size of the motor for driving the rear wheel due to the limited installation space, resulting in a disadvantage in terms of power performance.

- Hereinafter, a battery unit for a vehicle according to various exemplary embodiments of the present disclosure and an underbody of the vehicle including the same will be described in detail with reference to the accompanying drawings. First of all, a battery unit according to an exemplary embodiment of the present disclosure and an installation structure of the battery unit will be described with reference to
FIGS. 1 to 10 . - Referring to
FIGS. 1 to 10 , the battery unit according to an exemplary embodiment of the present disclosure may be fixedly disposed under acenter floor 210 of the vehicle, and configured to allow apropeller shaft 320 of adriving device 300 of the vehicle to pass through thebattery unit 100 in a front-rear direction of the vehicle to transmit power to arear wheel 230. - The
battery unit 100 according to an exemplary embodiment of the present disclosure may include a battery case having an upper case 110 a and alowercase 110 b forming a sealed internal space,battery modules 120 fixedly installed in the sealed internal space of the battery case, and a battery management system (BMS) 130 configured to monitor and manage voltages, currents, temperatures, and the like of thebattery modules 120 or battery cells in thebattery modules 120. - The
lower case 110 b of thebattery unit 100 according to an exemplary embodiment of the present disclosure may be divided into twobattery compartments 140 disposed in a direction toward opposite sides of the vehicle, respectively, such that thebattery modules 120 are accommodated therein, and a connectingportion 150 bent to be convex upwardly between thebattery compartments 140 to connect the twobattery compartments 140 to each other. The uppercase 110 a may cover an upper side of thelower case 110 b, thereby forming a sealed internal space. The upper case 110 a may be formed to have a shape that corresponds to an upper end shape of thelower case 110 b. Thebattery module 120 may include a plurality of battery cells electrically connected to each other. A voltage of thebattery module 120 may be determined based on whether the plurality of battery cells included therein are connected to each other in series or in parallel. - In various exemplary embodiments of the present disclosure, the two
battery modules 120 may be arranged in the twobattery compartments 140 spatially separated from each other by the connectingportion 150, respectively, and theBMS 130 may be installed in one of the twobattery compartments 140. Accordingly, highvoltage power wires 190 connected to one of thebattery modules 120 installed in one of the battery compartments 140 need to extend to the other one of the battery compartments 140. In particular, the wires may be arranged along the connectingportion 150 connecting the twobattery compartments 140 to each other. - Meanwhile, the
battery unit 100 may be fixedly installed under thecenter floor 210 of the vehicle outside the vehicle, and thecenter floor 210 may have acenter tunnel 211 that protrudes upwardly, bent, and that extends in the front-rear direction of the vehicle. Thebattery unit 100 may be installed such that the above-describedbattery compartments 140 of thebattery unit 100 are positioned on the left and right sides of thecenter tunnel 211, respectively. In addition, the connectingportion 150 may be bent to protrude upwardly, like thecenter tunnel 211 of thecenter floor 210, to install thebattery unit 100 under thecenter floor 210 of the vehicle in a state where the connectingportion 150 is inserted into thecenter tunnel 211. - In other words, the connecting
portion 150, which is a portion protruding upwardly while connecting upper sides of the battery compartments 140 positioned on both sides of the vehicle with respect to thecenter tunnel 211, may be indented along thecenter tunnel 211. In addition, aninstallation space 160 that is open in the front-rear direction of the vehicle may be formed under the connectingportion 150 between the two battery compartments 140. - In an exemplary embodiment of the present disclosure, the
propeller shaft 320 of thedriving device 300 of the vehicle may be disposed in theinstallation space 160. In other words, in thebattery unit 100 according to an exemplary embodiment of the present disclosure, since theinstallation space 160 is formed under the case, even when thebattery unit 100 is installed under thecenter floor 210 of the vehicle, it may be possible to secure a space for disposing thepropeller shaft 320 transmitting power from apower train 310, which is positioned at the front of the vehicle, to the rear wheel. - Meanwhile, the
battery unit 100 according to an exemplary embodiment of the present disclosure may further include a reinforcingstructure 170 for protecting the wires in the event of an impact. In addition, thebattery unit 100 according to an exemplary embodiment of the present disclosure may further include aconnection patch 180 for fixing the reinforcingstructure 170 to the case of thebattery unit 100. - When the
battery unit 100 is installed under thecenter floor 210 of the vehicle, if a collision occurs on a side surface of the vehicle, aseat cross member 270 of a vehicle body installed on thebattery unit 100 may be pushed downwardly into thebattery unit 100, and an upper portion of thebattery unit 100 may be damaged. As described above, thelower case 110 b of thebattery unit 100 according to an exemplary embodiment of the present disclosure has the connectingportion 150 that is convex upwardly, and the highvoltage power wires 190 forming the electrical connection with thebattery modules 120 are disposed on the connectingportion 150. Accordingly, in the event of the collision on the side surface of the vehicle, the highvoltage power wires 190 may be damaged by the intrusion of theseat cross member 270 thereinto, thereby causing a dangerous situation in which the high voltage wires are exposed to the outside. - To prevent such a dangerous situation that may occur when vehicle collides, in the present disclosure, the reinforcing
structure 170 made of a material having a rigidity that is high enough to secure a predetermined height may be fixedly disposed in an area corresponding to the connectingportion 150. The reinforcingstructure 170 may have a shape that corresponds to the curved surface of the connection portion of thelower case 110 b, and may include alower plate 171 fixed to thelower case 110 b in the area that corresponds to the connectingportion 150, anupper plate 172 spaced apart from thelower plate 171 at a predetermined distance, and supports 173 each connected to thelower plate 171 and theupper plate 172. - The
lower plate 171, theupper plate 172, and thesupports 173 may be manufactured in an integral type, and the reinforcingstructure 170 may include a plurality ofsupports 173 to implement a hollow structure with a plurality of hollows C1 between thelower plate 171 and theupper plate 172. Thelower plate 171 may have apertures C2 allowing a coupling means attached to thelower case 110 b, such as studs, to penetrate therethrough, and theupper plate 172 may have apertures C3 allowing a tool or the like for coupling the reinforcingstructure 170 to the coupling means to penetrate therethrough at areas corresponding to the apertures C2. - A plurality of reinforcing
structures 170 may be installed on the connectingportion 150 of thelower case 110 b, and the high-voltage power wires 190 may be arranged between the plurality of reinforcingstructures 170, thereby preventing thepower wires 190 from being damaged by the intrusion of an external structure (e.g., the seat cross member of the vehicle body) thereinto in the event of an impact. In this way, in an exemplary embodiment of the present disclosure, thepower wires 190 in thebattery unit 100 may be prevented from being damaged when an accident occurs, thereby preventing a secondary accident such as an electric shock caused by the exposure to the high voltage. - To fixedly install the above-described reinforcing
structure 170 on thelower case 110 b, thebattery unit 100 according to an exemplary embodiment of the present disclosure may further include aconnection patch 180. Theconnection patch 180 may be disposed between thelower case 110 b and the reinforcingstructure 170, and theconnection patch 180 may be fixedly installed on thelower case 110 b by bonding at least a portion of a surface thereof contacting thelower case 110 b to thelower case 110 b through welding or the like. Theconnection patch 180 may include a plurality ofstuds 181 that protrude from an exposed surface thereof in a direction opposite to thelower case 110 b to fix the reinforcingstructure 170 thereto. - At least some of the
studs 181 may be arranged to correspond to the position where the reinforcingstructure 170 is installed, and the reinforcingstructure 170 may be coupled to thestuds 181 using bolts B. In other words, the reinforcingstructure 170 may be fixed onto theconnection patch 180 by disposing the reinforcingstructure 170 such that some of thestuds 181 are arranged in the apertures C2 formed in thelower plate 171 of the reinforcingstructure 170 and then bringing the tool through the apertures C3 formed in theupper plate 172 of the reinforcingstructure 170 to fasten the bolts B to thestuds 181. - The rest of the
studs 181 may be used to fix thepower wires 190 that extend from one of the battery compartments 140 (e.g., a first battery component) to the other one of the battery compartments 140 (e.g., a second battery component) of thelower case 110 b. In other words, at least some of thestuds 181 positioned between the two fixed reinforcingstructures 170 may be used to fix thepower wires 190. For example, the power wires 19 may be fixed to thestuds 181 using wire fixing pins or the like, to stably position thepower wires 190 between the two reinforcingstructures 170. - Next, an underbody of the vehicle according to an exemplary embodiment of the present disclosure will be described with reference to all the remaining drawings.
FIG. 11 is an exploded perspective view of a front cross member and a rear cross member provided in an underbody of the vehicle according to an exemplary embodiment of the present disclosure,FIG. 12 is a bottom perspective view illustrating a state where the front cross member and the rear cross member are coupled to the center floor in the underbody of the vehicle according to an exemplary embodiment of the present disclosure, andFIGS. 13 and 14 are views for explaining examples of a coupled structure of the front cross member and the seat cross member in the underbody of the vehicle according to an exemplary embodiment of the present disclosure. - The
driving device 300 of the vehicle may include apower train 310 including an engine and a motor, and apropeller shaft 320 that transmits power from thepower train 310. Thepower train 310 may be fixedly installed on a sub-fame 220 positioned at the front of the vehicle, and thepropeller shaft 320 may be disposed to extend in the front-rear direction of the vehicle, with one end thereof being connected to thepower train 310. As described above, thepropeller shaft 320 may be disposed in theinstallation space 160 under the connectingportion 150 of thebattery unit 100. Although not illustrated, an exhaust pipe that extends from thepower train 310 to the rear of the vehicle may also be disposed in theinstallation space 160. - As already known in the related art, the
propeller shaft 320 of the vehicle is a component that transmits power from thepower train 310 to therear wheel 230. Since the power generated from thepower train 310 is transmitted to therear wheel 230 through thepropeller shaft 320, the rear wheel 203 may be driven by the power of thepower train 310 mounted at the front of the vehicle. - Since the
battery unit 100 is installed under thecenter floor 210, afront cross member 400 and arear cross member 500 are fixedly installed under thecenter floor 210 at the front and the rear of thebattery unit 100, respectively. Both thefront cross member 400 and therear cross member 500 may be structures extending in a direction toward the opposite sides of the vehicle, with both ends being connected to sidesills 240 positioned on the left and right sides of the vehicle, respectively, thereby forming load paths toward theside sills 240. - In addition, the
front cross member 400 may be connected to rear ends offront side members 250 to form load paths for transmitting a load to thefront side members 250, and therear cross member 500 may be connected to front ends ofrear side members 260 to form load paths for transmitting a load to therear side members 260. Since both thefront cross member 400 and therear cross member 500 are connected to vehicle body structures (e.g., the center floor, the side sills, the front side members, and rear side members), it is possible to increase a rigidity of a vehicle body, thereby improving ride and handling (R&H) performance and noise, vibration, and harshness (NVH) performance of the vehicle. - Since the
battery unit 100, which is positioned under thecenter floor 210 outside the vehicle, is installed such that an outer perimeter thereof is surrounded by theside sills 240 positioned on the opposite sides and thefront cross member 400 and therear cross member 500 positioned on the front and rear sides, the installation position of thebattery unit 100 may be regulated by theside sills 240 positioned on the opposite sides and thefront cross member 400 and therear cross member 500 positioned on the front and rear sides, and furthermore, thebattery unit 100 may be sufficiently protected against impacts from the front, rear, and lateral sides of the vehicle. - The
propeller shaft 320 of thedriving device 300, which is disposed to pass through theinstallation space 160 under the connectingportion 150, may be mounted on at least one of thefront cross member 400, therear cross member 500, and thebattery unit 100 to have a strong coupling force. Theseat cross member 270 may be coupled on thecenter floor 210 while being disposed in the left-right direction, and thefront cross member 400 may be disposed to vertically overlap theseat cross member 270 with thecenter floor 210 interposed there between. The vertical overlapping structure of theseat cross member 270 and thefront cross member 400 makes it possible to secure further improved durability, thereby further enhancing the stiffness and the rigidity of the vehicle body. - As another example, the
front cross member 400 may be connected to theseat cross member 270 throughflanges center floor 210 interposed there between, while being disposed in front of or behind theseat cross member 270. Each of thefront cross member 400 and therear cross member 500 includes twoside parts 410 or 510 and aconnection part 420 or 520 connecting the twoside parts 410 or 510. Theside part 410 or 510 may be formed in an approximately straight shape with a U-shaped cross section, and theconnection part 420 or 520 may be formed in a tunnel shape to be convex upwardly with a U-shaped cross section like theside part 410 or 510. - The
connection part 420 or 520 may be installed to be inserted into thecenter tunnel 211 of thecenter floor 210. All outward ends of theside parts 410 and 510 are connected to theside sills 240 of the vehicle to form load paths in a direction toward the opposite sides, and inward ends of theside parts 410 and 510 are coupled to opposite ends of theconnection parts 420 and 520 to overlap each other, thereby maintaining a strong coupling force. All of theside parts 410 and 510 and theconnection parts 420 and 520 may be open upwardly due to the U-shaped cross section, and flanges 411, 421, 511, and 521 of the upwardly open portions may be coupled to a lower surface of thecenter floor 210 in surface contact. Accordingly, thecenter floor 210, theside sills 240, theside parts 410 and 510, and theconnection parts 420 and 520 form sealedclosed spaces 280 therebetween. The sealedclosed spaces 280 make it possible to further enhance the stiffness and the rigidity of the vehicle body. - The
connection part 420 or 520 has coupling surfaces 422 or 522 formed at both ends thereof for thepropeller shaft 320 to be coupled thereto, and beads 423 or 523 are formed on both sides of the coupling surfaces 422 or 522 for theside parts 410 or 510 to be connected thereto. The coupling surfaces 422 or 522 may be preferably formed to be plane to enhance a coupling force between theconnection part 420 or 520 and thepropeller shaft 320, but are not limited thereto. The coupling surfaces 422 or 522 may be formed in the same shape as the mounting surface of thepropeller shaft 320 to couple theconnection part 420 or 520 and thepropeller shaft 320 in surface contact. In addition, the beads 423 or 523 formed on theconnection part 420 or 520 are formed to be connected up to theside parts 410 or 510. Through the beads 423 and 523, it may be possible to further enhance the rigidity of the coupled portions between theconnection part 420 or 520 and theside parts 410 or 510. - A first reinforcing
bracket 430 or 530 may be coupled to an inner surface of each of theside parts 410 or 510. The first reinforcingbracket 430 coupled to theside part 410 of thefront cross member 400 may be coupled to a front end of alongitudinal member 700 to be described later, and the first reinforcing bracket 530 coupled to the side part 510 of therear cross member 500 may be coupled to a rear end of thelongitudinal member 700 to be described later. Since the first reinforcingbrackets 430 and 530 are coupled to a portion where thefront cross member 400 and thelongitudinal member 700 are coupled to each other and a portion where therear cross member 500 and thelongitudinal member 700 are coupled to each other, respectively, it may be possible to further enhance the rigidity of the coupled portions. - A second reinforcing
bracket 440 or 540 for reinforcing the rigidity of the coupled portion may be coupled to each of the coupling surfaces 422 or 522 of theconnection part 420 or 520 to which thepropeller shaft 320 is coupled. Thebattery unit 100, which is installed under thecenter floor 210 outside the vehicle, may be supported on the lower side thereof and connected to vehicle body structures by a plurality oftransverse members 600 and a plurality oflongitudinal members 700. - In other words, in the
battery unit 100, the plurality oftransverse members 600 extending in the left-right direction and spaced apart from each other in the front-rear direction are coupled to the lower surfaces of the battery compartments 140, and thelongitudinal members 700 extending in the front-rear direction are coupled to the lower surfaces of the battery compartments 140 to position onelongitudinal member 700 for each of the battery compartments 140. In addition, thebattery unit 100 may further include a connectingportion reinforcing member 800 indented and coupled into the connectingportion 150 while extending in the front-rear direction along theinstallation space 160. - The
transverse member 600 may be installed across thelongitudinal member 700. In particular, a first end of thetransverse member 600 may be connected to theside sill 240 of the vehicle and a second end of thetransverse member 600 may be connected to the connectingportion reinforcing member 800 to form a load path in a direction toward the side of the vehicle. In addition, since thetransverse member 600 is connected to thelongitudinal member 700, it may also be possible to form a load path in the front-rear direction. - As another example, the
transverse members 600 may be positioned on the left and right sides of thelongitudinal member 700, respectively, such that first ends of thetransverse members 600 are connected to the left and right sides of thelongitudinal member 700, respectively, and the second ends of thetransverse members 600, which are not connected to thelongitudinal member 700, are connected to theside sill 240 and the connectingportion reinforcing member 800, respectively. In this structure, thetransverse member 600 and thelongitudinal member 700 do not vertically overlap each other, resulting in an advantage that it may be possible to reduce a vertical height as compared with when the members vertically overlap each other. - Each of the
side sills 240 positioned on the left and right sides of the vehicle may include anupper surface 241, alower surface 242, and aside surface 243 when viewed in its longitudinal section, and the left and right ends of thecenter floor 210 are connected to the side surfaces 243 of theside sills 240, respectively. Accordingly, anaccommodation space 290 that is open downwardly may be formed under thecenter floor 210 by the lower surface of thecenter floor 210 and theside surface 243 of theside sill 240. - The
battery compartment 140 of thebattery unit 100 may be installed in theaccommodation space 290, to accommodate an upper portion of thebattery compartment 140 in theaccommodation space 290, and a lower portion of thebattery compartment 140 protrudes downwardly beyond theside sill 240. This installation structure of thebattery compartment 140 makes it possible to not only lower thecenter floor 210 as close to the ground as possible, thereby securing a sufficient indoor space, but also dispose most of the upper portion of thebattery compartment 140 in theaccommodation space 290, thereby spacing thebattery compartment 140 distant from a road surface at a sufficient distance. - The battery unit for the vehicle and the underbody of the vehicle including the same are advantageous in terms of marketability in that the battery unit is fixedly installed under the center floor outside the vehicle, thereby making it possible to maximally use a trunk or luggage space.
- Particularly, the battery unit for the vehicle and the underbody of the vehicle including the same are advantageous in terms of vehicle manufacturing cost, weight, and fuel efficiency in that, while the battery unit is installed under the center floor, the battery unit may secure a space for installing the propeller shaft constituting the driving device of the vehicle to transmit power to the rear wheel, thereby implementing a four-wheel drive without using a separate motor for driving the rear wheel.
- Further, the battery unit for the vehicle and the underbody of the vehicle including the same are advantageous in that the battery unit installed under the center floor is connected to vehicle body structures, such as the side sills, the front side members, and the rear side members, through the transverse members, the longitudinal members, the front cross member, the rear cross member, and the like, thereby enhancing the rigidity of the vehicle body and improving ride and handling (R&H) performance and noise, vibration, and harshness (NVH) performance of the vehicle.
- In addition, the battery unit for the vehicle and the underbody of the vehicle including the same are advantageous in that the reinforcing member is installed on the connecting portion in the battery unit, thereby preventing the power wires in the battery unit from being damaged even if another member intrudes on the battery unit when the vehicle collides, and accordingly, preventing a secondary accident such as an electric shock resulting from the exposure to the high voltage.
- The effects obtainable from the present disclosure are not limited to the above-mentioned ones, and other effects that are not mentioned above may be clearly understood from the description above by those having ordinary knowledge in the field of technology to which the present disclosure pertains.
- Although the present disclosure has been shown and described with respect to specific embodiments, it will be apparent to those having ordinary skill in the art that the present disclosure may be variously modified and altered without departing from the spirit and scope of the present disclosure as defined by the following claims.
