The present invention relates to a power supply device for a hybrid electric vehicle, and more particularly, to a hybrid electric vehicle power supply device driven by variable operation of an engine and a motor, comprising a battery module assembly including a plurality of secondary batteries capable of charging and discharging And an electric device assembly interlocked with the battery module assembly and converting the electric motor into electricity for the operation of the motor and the electric field of the vehicle, wherein each assembly includes a frame member for coupling and mounting to a predetermined portion of the vehicle. Frame member), and the assemblies are related to a power supply unit mounted to a predetermined portion of a vehicle in a state of being embedded in one housing case in proximity to each other.

Recently, secondary batteries capable of charging and discharging have been widely used as energy sources of wireless mobile devices. Secondary batteries are also attracting attention as a power source for electric vehicles (EVs) and hybrid electric vehicles (HEVs), which are proposed as a way to solve air pollution in conventional gasoline and diesel vehicles that use fossil fuels. .

One or two or three battery cells are used for small mobile devices, whereas medium and large battery modules, which are electrically connected to a plurality of battery cells, are used in medium and large devices such as automobiles due to the necessity of high output capacity.

Since the medium-large battery module is preferably manufactured in a small size and weight, the rectangular battery, the pouch-type battery, etc., which can be charged with high integration and have a small weight to capacity, are mainly used as battery cells of the medium-large battery module. In particular, a pouch-type battery using an aluminum laminate sheet or the like as an exterior member has attracted much attention in recent years due to its advantages such as low weight, low manufacturing cost, and easy deformation.

In order for the medium-large battery module to provide the output and capacity required by a given device or device, it is necessary to electrically connect a plurality of battery cells in series and maintain a stable structure against external force.

Therefore, in the case of constructing a medium-large battery module using a plurality of battery cells, since a large number of members are generally required for their mechanical fastening and electrical connection, the process of assembling these members is very complicated. Moreover, space is required for joining, welding, soldering, etc. a plurality of members for mechanical fastening and electrical connection, thereby increasing the size of the entire system. This increase in size is undesirable in view of the space limitations of the apparatus or device in which the medium-large battery module is mounted. Furthermore, in order to be efficiently mounted in a limited interior space such as a vehicle, a medium to large battery module having a more compact structure is required.

In addition, the power supply unit used in the hybrid battery vehicle is composed of a medium-large battery module composed of secondary batteries capable of charging and discharging, and a plurality of electrical devices for converting the electricity generated from the medium-large battery module into electricity suitable for the motor and electric equipment of the vehicle. The structure is more complicated and not easy to assemble.

Therefore, as described above, there is a high need for a power supply device that can be mounted on a hybrid electric vehicle, which is more compact, has excellent structural stability, and is easily assembled.

The present invention aims to solve the problems of the prior art as described above and the technical problems that have been requested from the past.

Specifically, an object of the present invention has a compact structure that can be stably mounted in a limited space in a limited space, such as a vehicle, easy to assemble, excellent structural stability against external impact power supply for a hybrid electric vehicle To provide.

The power supply device according to the present invention for achieving this object is a power supply device for a hybrid electric vehicle that is driven by the variable operation of the engine and motor, a battery module assembly consisting of a plurality of secondary batteries capable of charging and discharging, It includes an electric device assembly which is linked to the battery module assembly to convert the electric motor for the operation of the motor and the electric field of the vehicle, each assembly is a frame member for mounting and mounting to a predetermined portion of the vehicle (mounting frame member) It includes, the assembly is configured to be mounted to a predetermined portion of the vehicle in a state in which it is embedded in one housing case in close proximity to each other.

In the vehicle power supply apparatus according to the present invention, when the battery module assembly and the electric device assembly are stacked in one integrated housing case adjacent to each other, the battery module assembly and the battery device assembly are separately mounted at a predetermined position of the vehicle. Compared with that, the electrical transmission efficiency is increased by shortening the electrical wiring, and the power supply device can be easily attached and detached to the vehicle, so that the assembly work and the disassembly work as necessary can be easily performed.

Preferably, the battery module assembly and the electrical device assembly have an overall size similar to that of a hexahedron so as to minimize overall size and increase structural stability while being more compactly mounted in a limited space. It may be a structure that is mounted in a state in which the left side and the right side of the case in close proximity to each other. That is, these assemblies having approximately similar sizes and disposed in close proximity to each other form a compact structure while maintaining a stable fixed state by a housing case mounted on its outer surface.

Since the mounting frame members, which serve to couple and mount the power supply device according to the present invention to a predetermined portion of the vehicle, have a structure that is coupled to the respective assemblies, the housing case is mounted in a state where the assemblies are mounted in the housing case. Compared with the case of mounting directly on the corresponding part of the vehicle, the structural stability of the mounted state can be further improved. Specifically, since the assemblies (particularly, the battery module assembly) have a considerable weight per se, a large force may be applied to the assembly due to shaking, impact, etc. while driving the vehicle, and thus the coupling force to the mounting portion of the vehicle may be reduced. If designed to rely on the coupling force of the housing case, a very large force is added to the housing case. Therefore, when the housing case is not made of a high strength material or a structure of a large size, there is a high possibility of being destroyed by such external force. On the other hand, in the present invention, since the respective assembly that is subjected to a large force by the external force provides a coupling force to the mounting portion of the vehicle by the mounting frame member is directly bonded to them, such a problem does not occur.

In one preferred example, the mounting frame member may be a structure installed as a pair of members on each side of the battery module assembly and the electrical device assembly.

The structure of the battery module assembly for charging and discharging electricity as needed in the power supply device according to the present invention may vary, preferably, a plurality of rectangular battery modules in which a plurality of battery cells or unit modules are connected in series The dog is laminated two or more in its width direction (longitudinal direction) and height direction (lateral direction) to form a hexahedral structure (hexahedral stack) as a whole, and the outer peripheral edges of the hexahedral stack are fixed by a frame member. It can be configured as.

In the battery module assembly having such a structure, a plurality of rectangular battery modules are stacked in a longitudinal direction and a lateral direction to form a six-sided laminate, and the six-sided laminate is fixed by a frame member, thereby providing a compact and stable structure as a whole. Mechanical fastening and electrical connection can be made without the use of members.

The plurality of rectangular battery modules constituting the hexahedral stack, as described above, has a structure in which a plurality of battery cells or unit modules are connected to each other. For example, the rectangular battery module is formed by stacking two or more plate-shaped battery cells. Preferably, the rectangular battery module may be configured by stacking two or more unit modules.

The rectangular battery module has a rectangular parallelepiped shape with a large width to height, and a structure in which a six-sided laminate in which a plurality thereof is combined to form an approximately cube shape as a whole provides a very compact and stable structure as a whole.

In one preferred example, the input / output terminals of each of the battery modules are oriented to face one side (a) of the hexahedral stack, and a power switching module (PSM) is mounted on the alignment surface (a) of the input / output terminals. It may have a structure in which a BMS (Battery Management System) is mounted on the input / output terminal alignment surface (a) or its opposite surface (b). More preferably, the BMS is attached to the PSM and the input / output terminal alignment surface a.

The power switching module (PSM), a power switching module (BSM), and the battery management system (BMS), which are essential for the construction of medium-large battery module assemblies, are rectangular batteries. By being mounted adjacent to the input and output terminals of the module, it is possible to further simplify the electrical connection structure and thus the assembly process. In addition, by reducing the length of the electrical connection means, it is possible to prevent the increase of internal resistance, reduce the risk of disconnection of the connection means by external impact, etc., it is possible to effectively protect the input and output terminal portion of the battery module that can be structurally weak. .

The PSM and optionally the BMS, preferably, may be mounted in a structure in which the safety elements and the control elements are mounted on a plate that is fastened to a frame member that fixes corners of one side of the six-sided stack. Specifically, the PSM and the BMS may be configured to mount a plurality of devices on a plastic substrate and electrically connect them by a bus bar. Here, since the plastic substrate is coupled to the frame member, the plastic substrate may also serve to maintain the mold of the frame member.

In the power supply device of the present invention, the electrical device assembly which works in conjunction with the battery module assembly to convert the electric motor for the operation of the motor and the electric field of the vehicle, the battery cell for use as an AC power source for operating the motor of the vehicle Inverter that converts DC electricity generated from battery module assembly to AC electricity when discharging, and converts high voltage electricity of battery module assembly generated when battery cell is discharged into low voltage DC electricity to operate electric equipment of vehicle It may be configured to include a low voltage DC to DC converter (LDC).

The structure in which the mounting frame member is coupled to the inverter and the LDC may vary, but the coupling efficiency is increased and the structure is properly spaced between the inverter and the LDC. The LDC is coupled to the upper surface of the mounting frame member and the inverter is coupled to the lower surface. It may be a structure. In order to enable such a coupling structure, the mounting frame member is bent to a depth corresponding to the thickness of the LDC so as to cover the lower surface of the LDC. On the contrary, the inverter may be coupled to the upper surface of the mounting frame member and the LDC may be coupled to the lower surface.

In the power supply according to the present invention, the housing case serves to protect the battery module assembly and the electrical device assembly mounted therein from the outside, for example, the outer surfaces of the assemblies except for the surface to which the mounting frame member is coupled. It may be a structure surrounding the.

In one preferred embodiment, the housing case comprises a case body including a battery module assembly and an accommodating portion for loading the electrical device assembly, and a case cover coupled to the body, and storing the assemblies in the case body. The case body may be sealed by using a case cover in a state, and then mounted on a predetermined portion of the vehicle. As described above, in this mounting process, the coupling force to the corresponding part of the vehicle is substantially provided by the mounting frame member coupled to each assembly, and the housing case is additionally coupled to the frame member. To achieve.

Since the inverter, LDC, etc. constituting the electric assembly generate high heat of approximately 80 to 90 ° C., when such high heat is radiated to the battery module assembly, deterioration of the battery cells constituting the battery module is promoted, and in some cases, fired. Or an explosion may be caused.

Therefore, in order to prevent radiant heat from such a battery module assembly, it is preferable to include a structure between the battery module assembly and the electrical device assembly to prevent heat radiation from the electrical device assembly to the battery module assembly. It is.

Such radiation protection schemes can be very diverse, as described above, when the BMS, PSM, etc. are located on the battery module assembly facing the electrical device assembly, as a result, the heat shielding effect can be obtained to some extent, but the BMS , PSM, etc. may also cause deterioration or malfunction due to the radiant heat, so a more efficient radiant heat prevention structure is required.

In a first example, the radiation protection structure may be a heat insulating member mounted between the battery module assembly and the electrical device assembly. The heat insulating member is not particularly limited as long as it is made of a shape and a material which can prevent radiant heat of the electrical device assembly from being transferred to the battery module assembly.

In a second example, the radiation protection structure may be a barrier wall or the like extending from at least one side thereof in a housing case consisting of a case body and a case cover. The barrier wall may have both a form extending from the case body and a form extending from the case cover. In some cases, it may be added by attaching a separate barrier wall on the case body or case cover.

In a third example, the radiation protection structure is formed so that a passage through the central portion of the housing case passes through the space between the battery module assembly and the electrical device assembly, it may be in the form of inserting a separate structure therein. . For example, the through passage is connected to a ski through, and when a ski is inserted through the through passage, a barrier wall may be formed by itself. The 'ski-thru' is a through-hole formed in a rectangular shape on a metal panel that supports an indoor rear seat of the vehicle for mounting a ski plate in a trunk of a medium or large vehicle, and is generally connected to an armrest of the rear seat.

Power supply for a hybrid electric vehicle generates a lot of heat during the charging and discharging process of the battery module assembly and the operation of the electric assembly, it is necessary to efficiently remove it.

To this end, the housing case is preferably made of a structure capable of efficiently cooling the battery module assembly and the electrical device assembly. Specifically, an opening a penetrating the outside may be formed in the side of the case body, and an opening b may be formed in the side of the same case main body as the opening a. Preferably, the opening (b) is equipped with a suction cooling fan, the refrigerant introduced into the case through the opening (a) sequentially passes through the battery module assembly and the electrical device assembly, and then the opening (b) By being discharged to the outside, the heat of the battery module assembly generated by the charge and discharge of the battery cell, and the high heat generated in the electrical device assembly, such as an inverter, a voltage drop converter may be sequentially removed.
