The present invention relates to a battery module, a battery pack including the battery module, and an automobile including the battery pack.

Secondary batteries having high electrical characteristics such as high energy density and high ease of application according to the product group can be applied not only to portable devices but also to electric vehicles (EVs) or hybrid electric vehicles (HEVs) driven by electric driving sources It is universally applied. Such a secondary battery is not only a primary advantage that the use of fossil fuel can be drastically reduced, but also produces no by-products resulting from the use of energy, and thus is attracting attention as a new energy source for enhancing environmental friendliness and energy efficiency.

Types of secondary batteries widely used today include lithium ion batteries, lithium polymer batteries, nickel cadmium batteries, nickel metal hydride batteries, and nickel-zinc batteries. The operating voltage of such a unitary secondary battery cell, that is, the unit battery cell is about 2.5V to 4.2V. Therefore, when a higher output voltage is required, a plurality of battery cells may be connected in series to form a battery pack. In addition, a plurality of battery cells may be connected in parallel according to a charge / discharge capacity required for the battery pack to form a battery pack. Therefore, the number of battery cells included in the battery pack can be variously set according to the required output voltage or the charge / discharge capacity.

Meanwhile, when a plurality of battery cells are connected in series / parallel to constitute a battery pack, a battery module including a plurality of battery cells is first configured, and other components are added using the plurality of battery modules, Is a common method.

Since the battery pack of the multi-battery module structure is manufactured in such a manner that a plurality of secondary cells are densely packed in a narrow space, it is important to easily discharge heat generated from each secondary battery. Since the process of charging or discharging the secondary battery is performed by the electrochemical reaction as described above, if the heat of the battery module generated in the charging and discharging process can not be effectively removed, heat accumulation occurs and consequently deterioration of the battery module is promoted , In some cases ignition or explosion may occur.

Accordingly, a battery pack having a high output capacity and a battery pack including the battery module is necessarily required to have a cooling device for cooling battery cells built therein.

Generally, there are two types of cooling devices, air cooling type and water cooling type. Air cooling type is more widely used than water cooling type due to leakage current or waterproofing of secondary battery.

Since the power that can be produced by one battery cell is not so large, a commercialized battery module generally stacks a plurality of battery cells as many as necessary in the module case and packages them. In order to properly maintain the temperature of the secondary battery by cooling the heat generated in the process of generating electricity in each battery cell, a plurality of cooling fins corresponding to the area of the battery cell is inserted as a heat dissipating member in the middle of the battery cells . The cooling fins that absorb heat in each battery cell are connected to a heat sink provided at the bottom of the battery module through a cooling plate to transfer the heat, and the heat sink is cooled by cooling water or cooling air.

However, in the conventional battery module, the plurality of cooling fins inserted between the battery cells and the cooling plate deteriorate the volume ratio of the battery cells by the plurality of cooling fins and the cooling plate.
