## Abstract

A battery module includes a bus bar; and a plurality of battery packs electrically connected to each other by the bus bar and arranged in front and rear directions, wherein each of the plurality of battery packs comprises a front polarity display part and a rear polarity display part that display polarities of terminals in front and rear positions of the terminals, wherein the front polarity display part and the rear polarity display part are formed to have different heights.

## Claims

### Claim 1

A battery module comprising:
a bus bar; and
a plurality of battery packs electrically connected to each other by the bus bar and arranged in front and rear directions,
wherein each of the plurality of battery packs comprises a + terminal and a − terminal of different polarities and comprises a front polarity display part and a rear polarity display part that each display polarities of each terminal, the front polarity display part and the rear polarity display part respectively formed in front and rear of the + terminal and − terminal,
wherein the front polarity display part and the rear polarity display part are formed to have different heights.

### Claim 2 (depends on 1)

The battery module of claim 1, wherein the plurality of battery packs comprise a front case and a rear case that are coupled to face each other,
wherein the front polarity display part is integrally formed on the front case, and
wherein the rear polarity display part is integrally formed on the rear case.

### Claim 3 (depends on 1)

The battery module of claim 1, wherein the bus bar connects a front battery pack and a rear battery pack together, detours the rear polarity display part of the front battery pack, and crosses the front polarity display part of the rear battery pack.

### Claim 4 (depends on 1)

The battery module of claim 1, wherein a height of the rear polarity display part is greater than that of the front polarity display part.

### Claim 5 (depends on 1)

The battery module of claim 1, wherein the bus bar comprises:
a pair of coupling pieces coupled to terminals of different battery packs arranged in the front and rear directions; and
a connection piece formed between the pair of coupling pieces.

### Claim 6 (depends on 5)

The battery module of claim 5, wherein among the pair of coupling pieces, a coupling piece of one end and a coupling piece of the other end are formed to have different heights.

### Claim 7 (depends on 5)

The battery module of claim 5,
wherein the coupling pieces are laid flat with respect to an upper surface of the battery pack, and
the connection piece stands upright vertically with respect to the upper surface of the battery pack.

### Claim 8 (depends on 1)

The battery module of claim 1, wherein the plurality of battery packs are arranged in the front and rear directions in the same orientation and same polarities of the plurality of battery packs are connected to each other in parallel.

### Claim 9 (depends on 1)

The battery module of claim 1, wherein the plurality of battery packs comprise a front case and a rear case that are coupled to face each other,
wherein guides for guiding an assembly position of the bus bar are formed in a terminal periphery of the front case and the rear case.

### Claim 10 (depends on 9)

The battery module of claim 9, wherein the guides are integrally formed on the front case and the rear case.

### Claim 11 (depends on 9)

The battery module of claim 9, wherein the guides are formed in front and rear directions or left and right directions perpendicular to the front and rear directions.

### Claim 12 (depends on 9)

The battery module of claim 9, wherein the bus bar is guided by the guides and connects adjacent battery packs along a bent pattern.

### Claim 13 (depends on 1)

The battery module of claim 1, wherein the bus bar comprises two terminal holes at different heights.
