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.

First claim

What is claimed is:

1. A battery system, comprising:
a battery cell, wherein the battery cell comprises a proximal end and a distal end, wherein the proximal end comprises a positive terminal or a negative terminal, and wherein the distal end comprises a negative terminal or a positive 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, wherein the energy transfer plate couples to the distal end of the battery cell; and
a dielectric layer between the first and second busbars, wherein the dielectric layer comprises a conduit, and wherein the conduit is configured to receive a fluid that heats and/or cools the battery cell and the first and second busbars.

2. The battery system of claim 1 , wherein the energy transfer plate comprises a counterbore configured to receive the distal end of the battery cell.

3. The battery system of claim 1 , wherein the energy transfer plate comprises a conduit configured to receive a fluid that cools and/or heats the battery cell.

4. The battery system of claim 3 , wherein at least one fluid selected from the group consisting of the fluid in the conduit in the dielectric layer and the fluid in the conduit in the energy transfer plate is oil.

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

6. The battery system of claim 5 , wherein the protrusion extends through the aperture to electrically couple to the battery cell.

7. The battery system of claim 1 , wherein the energy transfer plate comprises a layer of thermally conductive resin, wherein the resin facilitates heat transfer from the battery cell to the energy transfer plate.
