## Abstract

A battery case is provided. The battery case includes a first fin and a second fin, wherein the first fin is stacked substantially parallel to the second fin. The first fin is separated from the second fin by an airgap. The battery case includes one or more battery cell packs, each of the one or more battery cell packs are disposed through an orifice on each the first fin and the second fin.

## Claims

### Claim 1

A trailer refrigeration unit comprising:
a refrigeration system including at least one compressor, an evaporator, a plurality of battery cell packs, and at least one fan;
a microcontroller circuit configured to operate the refrigeration system; and
a battery system providing power to one or more of the compressor and the at least one fan, the battery system being the sole power source for the compressor and the at least one fan, the battery system including:
a first fin and a second fin, wherein the first fin is stacked substantially parallel to the second fin;
wherein the first fin is separated from the second fin by an airgap; and
wherein a first battery cell pack of the plurality of battery cell packs is disposed through a first orifice on each of the first fin and the second fin;
wherein the first battery cell pack comprises:
a cylindrical housing, wherein a plurality of battery cells are arranged in the cylindrical housing;
wherein the cylindrical housing has a central, longitudinal housing axis and at least one of the plurality of battery cells has a central, longitudinal battery cell axis, the battery cell axis offset from and parallel to the housing axis.

### Claim 2 (depends on 1)

The trailer refrigeration unit of claim 1, wherein the battery system further comprises:
a third fin, wherein the third fin is stacked substantially parallel to the first fin and the second fin;
wherein the third fin is separated from the first fin and the second fin by an airgap; and
wherein the first battery cell pack is disposed through an orifice on the third fin.

### Claim 3 (depends on 1)

The trailer refrigeration unit of claim 1, wherein the battery system further comprises:
one or more support members affixed to each of the first fin and the second fin.

### Claim 4 (depends on 1)

The trailer refrigeration unit of claim 1, further comprising:
an environmental sensor operable to collect an environmental parameter in the trailer refrigeration unit.

### Claim 5 (depends on 4)

The trailer refrigeration unit of claim 4, wherein the at least one fan is operable to move air towards the battery system based at least in part on the environmental parameter.

### Claim 6 (depends on 1)

The trailer refrigeration unit of claim 1, wherein the first orifice is substantially cylindrical and sized to receive the first battery cell pack.

### Claim 7 (depends on 1)

The trailer refrigeration unit of claim 1, wherein the first fin and the second fin comprise a metal.

### Claim 8 (depends on 7)

The trailer refrigeration unit of claim 7, wherein the metal is aluminum.

### Claim 9 (depends on 1)

The trailer refrigeration unit of claim 1 further comprising:
a second battery cell pack and a third battery cell pack of the plurality of battery cell packs disposed through a second orifice on each of the first fin and the second fin; and
the first and the second fin are in thermal contact with the first battery cell pack.

### Claim 10 (depends on 1)

The trailer refrigeration unit of claim 1, wherein the trailer refrigeration unit does not include a fuel-based generator.
