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.

Abstract: A modular frame for a battery module includes: a floor that includes an electrically non-conductive material; end walls that are perpendicular to the floor and that include the electrically non-conductive material; and side walls that are perpendicular to the floor, that are perpendicular to the end walls, and that include the electrically non-conductive material. The modular frame further includes interior walls that include the electrically non-conductive material and that define: a first row of cell slots configured to receive a first plurality of prismatic cells; a second row of cell slots configured to receive a second plurality of prismatic cells; and a chamber disposed between the first and second rows of cell slots. The modular frame further includes a first and second apertures to the chamber. The first aperture is defined by the interior walls and the side walls. The second aperture is formed through one of the end walls.

Abstract: A battery pack according to the present disclosure includes a first module array, a second module array, and a center channel. The first module array includes a first frame and a first cassette of battery modules disposed within the first frame. The first cassette of battery modules includes a first plurality of prismatic cells and a first plurality of module terminals. The second module array includes a second frame and a second cassette of battery modules disposed within the second frame. The second cassette of battery modules includes a second plurality of prismatic cells and a second plurality of module terminals. The center channel extends through a center of the battery pack and connects the first module array to the second module array. The first plurality of module terminals and the second plurality of module terminals are disposed adjacent to the center channel on opposite sides of the center channel.
