Abstract:
Present embodiments are directed to a battery module including a venting assembly and a method of manufacturing the battery module. The venting assembly may, in certain embodiments, be designed to vent gases from a plurality of battery cells disposed in a housing of the battery module. Each of the plurality of battery cells may include a battery cell vent. The venting assembly may include a lid designed to be coupled to the housing and disposed over the battery cells in the housing. In some embodiments, the lid includes a vent chamber formed in the lid and designed to receive and direct gases vented from the plurality of battery cells away from the battery module.
Abstract:
Systems are disclosed for battery modules with cooling systems. In accordance with disclosed embodiments, the cooling system may be disposed against an external surface of a housing of the battery module. The cooling system may utilize a coolant to remove heat generated by cells within the battery module, to prevent the cells from aging prematurely. Embodiments of the cooling system may include cold plates, tubes, fins, and plates, or a combination thereof, which may route the coolant along the surface of the battery module housing. Such features may create a large effective cooling surface against the battery module housing to promote a high heat transfer rate from the cells to the coolant.
Abstract:
The present disclosure relates to a battery module. The battery module includes a housing defined by one or more walls. A wall of the housing includes an opening configured to create a passageway between an interior of the housing and an exterior of the housing. The battery module includes a connector barrel disposed within the opening. The connector barrel is a hollow conduit with a first open end opposite a second open end, and the connector barrel is configured to receive a low voltage signal connector through the first open end and a vehicle control module connector through the second open end. An external surface of the connector barrel includes a pair of protrusions configured to enable intimate contact between the wall of the housing and the connector barrel.
Abstract:
The present disclosure includes a group of electrically interconnected battery cells disposed within a housing. The disclosure also includes a major terminal of a battery module configured to be coupled to a load for powering the load. One or more portions of the major terminal are disposed within a recess in a surface of the housing. The present disclosure also includes a bus bar that provides an electrical pathway between the group of electrically interconnected battery cells and the major terminal. The bus bar is disposed within the housing.
Abstract:
A battery module mounting system includes a housing of the battery module configured to receive a plurality of electrochemical cells, a lid coupled to a side of the housing, and a cage configured to secure the housing to a vehicle. Additionally, the cage includes a coupling mechanism configured to engage with the lid in a tongue and groove configuration to block movement of the housing in at least three directions when engaged.
Abstract:
The present disclosure relates to a stacked cell manufacturing scheme for battery modules. A disclosed method of manufacturing a battery module includes assembling a plurality of prismatic battery cells of the battery module into a cell stack. The method includes compressing the cell stack using an actuating clamping mechanism, inserting the cell stack into a housing of the battery module with the actuating clamping mechanism engaged with and compressing the cell stack, and removing the actuating clamping mechanism from the cell stack. The housing of battery module maintains a compression of the cell stack above a predetermined threshold in the battery module after removing the actuating clamping mechanism.
Abstract:
A battery system having a bladed fuse connector and a method of operation of the bladed fuse connector are provided. The system may, in certain embodiments, include a printed circuit board (PCB) and a high current interconnect. The high current interconnect may be mounted to and extending upward from the PCB. The battery system may also include a fuse. The fuse may limit an amount of current flowing through the battery system. Additionally, the battery system may include a bladed fuse connector coupled between the high current interconnect and the fuse. The bladed fuse connector may carry a current between the high current interconnect and the fuse. To that end, the bladed fuse connector may include an S-shaped bend between the high current interconnect and the fuse.
Abstract:
A method of manufacturing a battery module for use in a vehicle is presented. The method may include disposing battery cells into a lower housing and disposing a lid assembly over the battery cells. The lid assembly may include a lid and bus bar interconnects disposed on the lid. The method may also include disposing a printed circuit board (PCB) assembly onto the lid assembly and electrically coupling portions of the lid assembly, portions of the PCB assembly, and the battery cells to each other.
Abstract:
A battery module includes a housing configured to receive a plurality of electrochemical cells, a skeletal frame coupled with the housing, and a framework disposed proximate to the skeletal frame. Moreover, the framework is substantially aligned with the skeletal frame and configured to transfer a force applied to the framework to the skeletal frame.
Abstract:
A printed circuit board (PCB) assembly includes a PCB and a high current interconnect mounted on the PCB. The high current interconnect is configured to electrically couple a first high current bladed component, a second high current bladed component, and a trace disposed on the PCB. The high current interconnect includes feet made of a conductive material that are coupled to the PCB. The trace is coupled to the feet via a weld.
