Abstract:
The present disclosure includes a battery module that includes a plurality of lithium ion battery cells disposed within a battery module packaging. Each of the plurality of lithium ion battery cells is individually held in place within the battery module packaging by a restraining medium. The restraining medium conformally covers a substantial portion of the surface of each of the plurality of lithium ion battery cells and prevents each of the plurality of lithium ion battery cells from expanding during operation of the battery module.
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:
Relays having internal connections on both sides of their switches may be used in conjunction with a connector that integrates both the normal relay switch control lines with the sensing conductors of a control module for a battery module of an energy storage device. In this manner, sensing conductors may be routed along with the switch control lines for the relay instead of separately as described above. This integration reduces the complexity and cost associated with the energy storage device, because it reduces the number of separately routed lines and also eliminates the external connections for at least some of the sensing conductors.
Abstract:
A printed circuit board (PCB) assembly may include a PCB and a high current interconnect mounted on the PCB. The high current interconnect may be 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 may include feet made of a conductive material that are coupled to the PCB. The trace may be coupled to the feet via a weld.
Abstract:
A system includes a lid disposed over battery cells in a battery module. The lid includes flexible fingers, and each of the flexible fingers aligns with a corresponding one of the battery cells. Each of the flexible fingers is configured to exert a downward force against the corresponding one of the battery cells, and the flexible fingers are configured to accommodate varying heights of the battery cells.
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:
The present disclosure relates to a battery module having a housing and a stack of battery cells disposed in a receptacle area of the housing, where each battery cell has a top having a battery cell terminal and a bottom, where the top of the battery cells face outwardly away from the receptacle area. The battery module includes an integrated sensing and bus bar subassembly positioned against the stack of battery cells and has a carrier, a bus bar integrated onto the carrier, and a biasing member integrated onto the carrier. The bus bar electrically couples battery cells in an electrical arrangement, and the biasing member is between the top of each battery cell and the carrier, where the biasing member has a first material, more compliant than a second material of the carrier, and the biasing member biases the stack of battery cells inwardly toward the housing.
Abstract:
A system includes a battery module having electrochemical cells and a housing configured to receive the electrochemical cells. The housing includes a first sidewall having a first surface and a second surface. The housing also includes cooling channels extending through the first sidewall of the housing from the first surface to the second surface, where the cooling channels are configured to permit fluid flow through the cooling channels for cooling the electrochemical cells. Each of the cooling channels includes a first cross-sectional area across the first surface of the first sidewall and a second cross-sectional area across the second surface of the first sidewall, where the first cross-sectional area is not equal to the second-cross sectional area. Each of the cooling channels also includes a tapered portion extending between the first-cross sectional area and the second cross-sectional area.

Abstract:
The present disclosure includes a battery module having a housing with a cell receptacle region defined by walls of the housing and configured to enable passage of electrochemical cells therethrough. The battery module also includes a bus bar carrier sealed in the cell receptacle region. The bus bar carrier includes a perimeter having flexible ribs extending along at least a majority of the perimeter and configured to enable intimate contact between the walls of the housing and the perimeter of the bus bar carrier.
