Referring to FIGS. 24 to 27 , the battery module assembly 100 according to an embodiment of the present invention includes a plurality of unit modules 200 stacked in a horizontal direction.

A plurality of stacked unit modules 200 are assembled by fastening means such as long bolts.

Each of these unit modules 200 includes a battery cell 210, a cartridge assembly 220, a cover member 260, and a sensing module 270.

The battery cells 210 are formed in a pair of plate-shaped (pouch-shaped) shapes, and are erected in a direction in which surface contact is made with each other.

And, the battery cell 210 has electrode terminals formed on both sides.

The pair of battery cells 210 are disposed on both sides of the cartridge assembly 220 with one cartridge assembly 220 interposed therebetween.

The cartridge assembly 220 is made up of a corresponding number of battery cells 210, and a pair of battery cells 210 are fixed.

The cover member 260 covers the cartridge assembly 220 and the battery cells 210 disposed on the cartridge assembly 220 .

The cover member 260 includes a side cover 261, a front cover 262 and a rear cover 263.

The side cover 261 covers both sides of the plurality of cartridge assemblies 220 and the battery cells 210 disposed on the cartridge assembly 220, and the cartridge assembly 220 and the battery cells fixed to the cartridge assembly 220 Electrode terminals of the battery cell 210 exposed on both sides of 210 are protected.

Due to this, the side cover 261 can effectively secure the safety of the battery cell 210 .

The front cover 262 covers the front surfaces of the plurality of cartridge assemblies 220 and the battery cells 210 fixed to the cartridge assemblies 220 .

The rear cover 263 covers the front surfaces of the plurality of cartridge assemblies 220 and the battery cells 210 to be fixed to the cartridge assemblies 220 .

The rear cover 263 includes a connector fixing part 264, a wire fixing part 265, a sensor through hole 266, and a sensor support 267.

The connector fixing part 264 fixes the temperature sensing connector 271 of the sensing module 270 and fixes the temperature sensing connector 271 to the top of the rear cover 263 .

Meanwhile, the temperature sensing connector 271 of the sensing module 270 coupled to the connector fixing part 264 is coupled to the connector fixing part 264 in a sliding manner.

To this end, the connector fixing part 264 includes a sliding protrusion 264_1.

When viewed from a plane, the sliding protrusion 264_1 extends in a horizontal direction from the connector fixing part 264 and is formed at a distance from the upper surface of the rear cover 263 in a vertical direction.

Accordingly, a groove to which the temperature sensing connector 271 of the sensing module 270 is coupled may be formed between the sliding protrusion 264_1 and the upper surface of the rear cover 263 .

The wire fixing part 265 is made of a pair, and when viewed from a plane, extends in a vertical direction, and is formed at a position spaced apart from the connector fixing part 264 on the upper surface of the rear cover 263 .

Also, the wire fixing part 265 fixes the sensor wire 272 of the sensing module 270 .

Accordingly, the pair of wire fixing parts 265 are spaced apart from each other to the extent that the sensor wire 272 can be fixed.

That is, the distance between the pair of wire fixing parts 265 is wider than or equal to the thickness of the sensor wire 272.

This wire fixing part 265 includes a holding member 265_1.

The holding member 265_1 extends from the ends of the pair of wire fixing parts 265 in directions facing each other.

Also, the distance between the pair of holding members 265_1 is smaller than the thickness of the sensor wire 272 inserted between the pair of wire fixing parts 265 .

Due to this, the wire fixing part 265 can effectively restrain the free movement of the sensor wire 272 on the top of the rear cover 263 and can effectively prevent the sensor wire 272 from being excessively bent.

In particular, the hooking member 265_1 can effectively prevent the sensor wire 272 fixed to the wire fixing part 265 from being separated from the wire fixing part 265 .

The sensor through hole 266 fixes the temperature sensor 273 of the sensing module 270 to the rear cover 263 and penetrates one surface and the other surface of the rear cover 263 .

That is, in the sensor through-hole 266, the sensing wire 263 of the sensing module 270 passes through the inside of the rear cover 263 so that the temperature sensor 273 connected to the sensor wire connects to the battery cell 210 to be measured. allow them to come into contact with each other.

Meanwhile, the location of the sensor through-hole 266 may be formed at various locations according to specifications of the battery module assembly 100 .

The sensor support 267 protrudes from the periphery of the sensor through-hole 266, and supports a portion of the temperature sensor 273 protruding from the sensor through-hole 266 while being fixed to the sensor through-hole 266.

Accordingly, the sensor support 267 supports the temperature sensor 273 protruding from the sensor through-hole 266, thereby effectively preventing the temperature sensor 273 from being separated from the rear cover 263.

The sensing module 270 is fixed to the rear cover 263, senses the temperature inside the unit module 200, and transfers the sensed temperature value to a control board of a battery management system (BMS).

On the other hand, although the sensing module 270 has been described as being fixed to the rear cover 263, it can also be fixed to various positions such as the side cover 261 or the front cover 262 depending on the usage environment or specifications of the battery module 100. do.

The sensing module 270 includes a temperature sensing connector 271 , a sensor wire 272 and a temperature sensor 273 .

The temperature sensing connector 271 is coupled to the connector fixing part 264 formed on the upper surface of the rear cover 263 .

To this end, the temperature sensing connector 271 includes a sliding groove 271_1.

The sliding groove 271_1 is formed below the temperature sensing connector 271 and is coupled to the sliding protrusion 264_1 of the connector fixing part 264 in a sliding manner.

Accordingly, since the temperature sensing connector 271 is coupled to the connector fixing part 264 in a sliding manner, assembly efficiency of the sensing module 270 and the rear cover 263 may be effectively increased.

One end of the sensor wire 272 extends from the temperature sensing connector 271, the middle area is fixed to the wire fixing part 265, and the other end is fixed to the sensor through-hole 266 while being supported by the sensor support 267. connected to the temperature sensor 273.

The temperature sensor 273 senses the temperature inside the unit module 200 and is coupled to the sensor through-hole 266 while being supported on the sensor support 267 .
