20120121949 | Vehicle Battery Packaging - A vehicle battery packaging for accommodating a plurality of longitudinal battery cells, wherein the battery cells are arranged in a frame in parallel with respect to their longitudinal axes, and wherein each battery cell has a first end and an opposite second end with respect to the longitudinal axis, the battery packaging including: a conductor plate adapted to electrically couple to the second ends of the battery cells; a cooling plate thermally coupled to the conductor plate; and a gap filler layer sandwiched between the conductor plate and the cooling plate. | 05-17-2012 |
20120141852 | Conductor Plate for a Vehicle Battery Module - In a conductor plate for a vehicle battery module, the vehicle battery module is adapted to accommodate a plurality of longitudinal battery cells. The battery cells are arranged in parallel with respect to their longitudinal axes, and each battery cell has a first end and an opposite second end with respect to its longitudinal axis. The conductor plate includes: a base part; and a plurality of longitudinal members. Each of the plurality of longitudinal members includes a first end and a second end, the first ends of the longitudinal members being connected to the base part, the base part and the plurality of longitudinal members being substantially arranged in a common plane. The longitudinal members are arranged spaced from each other such that an interval between two of the plurality of longitudinal members matches to an interval between two rows of the battery cells. | 06-07-2012 |
20120141853 | Battery Cell and Vehicle Battery Module - In a longitudinal battery cell for a vehicle battery module, the battery cell includes a first end and an opposite second end with respect to a longitudinal axis of the battery cell, and a lateral surface extending from the first end to the second end. The battery cell includes an attachment structure extending in an outward direction from the lateral surface at the second end for coupling the battery cell to the battery module. | 06-07-2012 |

20140234668 | Battery Housing with Single-Side Electrical Interconnects - A battery housing includes a battery frame that holds a plurality of battery cells. Each battery cell includes a positive terminal and a conducting structure at one end, a negative terminal at the opposite end, and a conductive shell that electrically couples the negative terminal to the conducting structure. An interconnect creates an electrical connection between two cells by contacting either the conducting structure or the positive terminal of each cell. The cells are positioned so that the positive terminals, conducting structures, and interconnect are all on the same side of the battery frame. As a result, the interconnect can be shorter in length. | 08-21-2014 |
20140234683 | Thermal Insulation of Battery Cells - A battery frame includes a plurality of battery cell compartments that are configured to hold battery cells. In one embodiment, each battery cell compartment includes a plurality of alignment features that protrude from an interior surface of the compartment by a protrusion distance. When a battery cell is inserted into the cell compartment, the alignment features make contact with the side of the battery cell to center the battery cell in the cell compartment and to create an air gap between the side of the battery cell and the interior surface of the cell compartment. The air gap reduces heat transfer from the battery cell to adjacent battery cells, which advantageously protects adjacent battery cells when a battery cell fails and releases a large amount of heat during a thermal runaway. | 08-21-2014 |
20140234686 | Thermal Interface and Thermal Management System for Battery Cells - A battery housing includes a heat spreader, a thermal interface that contacts a surface of the heat spreader, and a battery frame that is configured to hold a plurality of battery cells. When a battery cell is inserted into the battery frame, the thermal interface contacts the cell at the same end as the cell's negative terminal. As a result, the thermal interface allows heat to be transferred between the battery cell and the heat spreader. It is advantageous to make a thermal connection at the end with the negative terminal because the internal jelly roll structure of the battery cell causes the cell to have a higher thermal conductivity at its negative terminal. | 08-21-2014 |
