## Abstract

A battery system that includes a battery cell. The battery cell includes a proximal end and a distal end, where the proximal end is both a positive terminal and a negative terminal. The system also includes a first busbar that electrically couples to the negative terminal or the positive terminal. A second busbar is electrically coupled to the negative terminal or the positive terminal. An energy transfer plate couples to the distal end of the battery cell.

## Claims

A battery system, comprising:
a battery cell, wherein the battery cell comprises a proximal end and a distal end, and wherein the proximal end comprises a positive terminal and a negative terminal;
a first busbar, wherein the first busbar is configured to electrically couple to the negative terminal or the positive terminal;
a second busbar, wherein the second busbar is configured to electrically couple to the negative terminal or the positive terminal;
an energy transfer plate, configured to receive a fluid, wherein the energy transfer plate couples to the distal end of the battery cell;
a pump coupled to the energy transfer plate;
a heater configured to heat the fluid; and
an energy transfer conduit abutting the battery and weaving through the first busbar and second busbar;
and wherein,
the pump is configured to pump the fluid through the energy transfer plate and the energy conduit.

### Claim 2 (depends on 1)

The battery system of claim 1, comprising a temperature sensor, wherein the temperature sensor is configured to measure a temperature of at least one of the battery cell, the first busbar, and the second busbar.

### Claim 3 (depends on 2)

The battery system of claim 2, comprising a controller coupled to the temperature sensor and to the pump, wherein the controller is configured to control fluid flow through the energy transfer plate with the pump in response to the temperature of at least one of the battery cell, the first busbar, and the second busbar.

### Claim 4 (depends on 1)

The battery system of claim 1, wherein the fluid is oil.

### Claim 5 (depends on 1)

The battery system of claim 1, wherein first busbar comprises a protrusion and the second busbar defines an aperture.

### Claim 6 (depends on 5)
