Abstract:
1. A battery assembly comprising: at least one battery pack; a plurality of prismatic cells of said at least one battery pack; and at least one cell retaining element extending between two of said prismatic cells and presenting a pair of mechanical devices with one of said devices mechanically engaging one of said prismatic cells and another of said devices mechanically engaging the other of said prismatic cells thereby locking said prismatic cells with said cell retaining element and forming contact between said at least one cell retaining element and said prismatic cells for manipulating temperature of said prismatic cells through said at least one cell retaining element, wherein the at least one retaining element includes a heat transfer element, a first inner frame, a second inner frame, a first outer frame, and a second outer frame; the first inner frame and the second inner frame cooperating to hold the heat transfer element; the heat transfer element extends between a first prismatic cell and a second prismatic cell and is accessible through an open central portion of the first inner frame and the heat transfer element is accessible through an open central portion of the second inner frame, a central portion of the heat transfer element maintains the first prismatic cell and the second prismatic cell in a spaced apart arrangement; the first outer frame cooperates with the first inner frame to hold the first prismatic cell and the second outer frame cooperates with the second inner frame to hold the second prismatic cell; and the first prismatic cell is accessible through an open central portion of the first outer frame and the second prismatic cell is accessible through an open central portion of the second outer frame.
