Multi-cell battery module with integral cooling and assembly aids
First Claim
1. A battery pack comprising:
- a frame member that includes a floor, that includes walls formed perpendicular to the floor, and that includes an aperture defined by the walls,wherein the frame member is formed from an electrically non-conductive plastic;
a first lithium ion cell that includes a first positive terminal and a first negative terminal, that includes a first electrically conductive housing, and that is disposed between the walls of the frame member,wherein the first positive terminal is electrically connected to the first electrically conductive housing;
a second lithium ion cell that includes a second positive terminal and a second negative terminal, that includes a second electrically conductive housing, and that is disposed between the walls of the frame member,wherein the second positive terminal is electrically connected to the second electrically conductive housing; and
an isolation plate moveable relative to the frame member in a first condition along at least two orthogonal axes within the frame member, the isolation plate directly contacting both the first and second electrically conductive housings and electrically isolating the first electrically conductive housing from the second electrically conductive housing,wherein the isolation plate is formed from the electrically non-conductive plastic.

Abstract
A battery pack includes a frame member, first and second lithium ion cells, and an isolation plate. The frame member includes a floor, walls formed perpendicular to the floor, and an aperture defined by the walls. The frame member is formed from an electrically non-conductive plastic. The first lithium ion cell includes a first positive terminal, a first negative terminal, and a first electrically conductive housing. The first positive terminal is electrically connected to the first electrically conductive housing. The second lithium ion cell includes a second positive terminal, a second negative terminal, and a second electrically conductive housing. The second positive terminal is electrically connected to the second electrically conductive housing. The isolation plate directly contacts both the first and second electrically conductive housings and electrically isolates the first electrically conductive housing from the second electrically conductive housing. The isolation plate is formed from the electrically non-conductive plastic.
