## Abstract

A battery pack according to an embodiment of the present disclosure includes one or more first battery modules, each including a plurality of battery cells, and one or more second battery modules, each disposed adjacent to the first battery modules and including a plurality of battery cells, wherein the first battery modules and the second battery modules are different from each other in a maximum state of charge (SOC).

## Claims

### Claim 1

A battery pack, comprising:
one or more first battery modules, each including a plurality of battery cells; and
one or more second battery modules, each disposed adjacent to the first battery modules and including a plurality of battery cells,
wherein the first battery modules and the second battery modules are different from each other in a maximum state of charge (SOC).

### Claim 2 (depends on 1)

The battery pack of claim 1, wherein:
the maximum SOC of the one or more first battery modules is 100 %, and the maximum SOC of the one or more second battery modules is 90 %.

### Claim 3 (depends on 1)

The battery pack of claim 1, further comprising:
a control unit connected to each of the one or more first battery modules and the one or more second battery modules to perform charging and SOC control.

### Claim 4 (depends on 3)

The battery pack of claim 3, wherein:
the control unit is configured to control the SOC of the one or more first battery modules to be 100 %, and the SOC of the one or more second battery modules to be 90 % when the charging is performed.

### Claim 5 (depends on 1)

The battery pack of claim 1, wherein:
any one of the one or more first battery modules is disposed to be surrounded by the one or more second battery modules.

### Claim 6 (depends on 1)

The battery pack of claim 1, wherein:
any one of the one or more second battery modules is disposed to be surrounded by the one or more first battery modules.

### Claim 7 (depends on 1)

The battery pack of claim 1, wherein:
the one or more first battery modules and the one or more second battery modules are alternately disposed.

### Claim 8 (depends on 1)

The battery pack of claim 1, wherein:
the battery cells included in the first battery modules and the battery cells included in the second battery modules have the same type.

### Claim 9 (depends on 1)

The battery pack of claim 1, further comprising:
a pack frame packaging the one or more first battery modules and the one or more second battery modules.

### Claim 10 (depends on 1)

A device, comprising:
at least one battery pack of claim 1.
