## Abstract

Provided is a battery that includes a battery module having a battery cell, and a cooler including an inlet part through which refrigerant flows in from outside, and an outlet part through which the refrigerant flows out, and configured to cool the battery module as the refrigerant circulates inside the cooler. The cooler includes an inlet side flow passage that communicates with the inlet part and is provided at a position overlapping a heating region, and an outlet side flow passage that communicates with the inlet side flow passage and the outlet part, and is provided at a position overlapping a non-heating region.

## Claims

### Claim 1

A battery, comprising:
a battery module having a battery cell; and
a cooler including an inlet part through which refrigerant flows in from outside, and an outlet part through which the refrigerant flows out, the cooler being configured to cool the battery module as the refrigerant circulates inside the cooler, wherein:
the battery module includes:
a heating region; and
a non-heating region; and
the cooler includes:
an inlet side flow passage that communicates with the inlet part and is provided at a position overlapping the heating region; and
an outlet side flow passage that communicates with the inlet side flow passage and the outlet part and is provided at a position overlapping the non-heating region.

### Claim 2 (depends on 1)

The battery according to claim 1, wherein:
a plurality of battery cells is laminated in the battery module; and
the inlet side flow passage is provided at a position overlapping the heating region in a laminating direction in which the battery cells are laminated.

### Claim 3 (depends on 1)

The battery according to claim 1, wherein:
the battery module includes:
a coated region in which an active material is coated;
an uncoated region in which the active material is not coated; and
a seal part provided to cover an outer peripheral side of the battery cell;
the heating region is the coated region; and
the non-heating region is the uncoated region and the seal part.

### Claim 4 (depends on 1)

The battery according to claim 1, wherein the refrigerant moves from the inlet side flow passage to the outlet side flow passage.

### Claim 5 (depends on 1)

The battery according to claim 1, wherein the refrigerant is fluid.

### Claim 6 (depends on 1)

A vehicle comprising the battery according to claim 1.
