摘要:
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.

A lid assembly 56 for use in a battery module 22 includes a lid 290 with apertures 292 extending through the lid 290 in a vertical direction, where each of the apertures 292 is configured to receive a terminal 232 of a battery cell 54 of the battery module 22. The lid assembly 56 also includes one or more extensions 332 extending away from the lid 290 in the vertical direction. Each of the one or more extensions 332 is configured to couple the lid 290 to a printed circuit board assembly 58 of the battery module 22. The lid assembly 56 also includes walls 334 extending away from the lid 290 in the vertical direction. Each of the walls 334 is configured to extend between a first terminal 232 of a first battery cell 54 and a second terminal 232 of a second battery cell 54.
摘要:
A battery module includes a housing configured to hold prismatic battery cells within a space defined by four interior walls of the housing. The housing includes a first interior wall that includes partitions (e.g., ribs) extending upwards from a bottom of the housing and a second interior wall that includes partitions extending upwards from the bottom of the housing. The first interior wall faces opposite the second interior wall. The partitions disposed on the first interior wall and the partitions disposed on the second interior wall define slots between adjacent partitions, where each of the slots increases in width between the adjacent partitions from the bottom of the housing upwards. Each of the slots is configured to retain one of the prismatic battery cells.

Present embodiments include a series of lithium battery modules (28A-28C) having a plurality of electrochemical cells having different electrical characteristics such as voltages and/or capacities. The battery modules are each constructed using components, architectures, production methods, among other things, in common with each other. The lithium ion battery modules may include a first battery module type having a first capacity and a first voltage, a second battery module type having a second capacity and a second voltage, and, in some embodiments, additional battery module types having different voltages and/or capacities. The lithium ion battery modules may all have the same footprint (42).
摘要:
A system includes a battery module (13) having electrochemical cells (30) and a housing (31) configured to receive the electrochemical cells (30). The housing (31) includes a first sidewall (52) having a first surface (33) and a second surface (54). The housing also includes cooling channels (50) extending through the first sidewall (52) of the housing (31) from the first surface (33) to the second surface (54), where the cooling channels (50) are configured to permit fluid flow through the cooling channels (50) for cooling the electrochemical cells (30). Each of the cooling channels (50) includes a first cross-sectional area across the first surface (33) of the first sidewall (52) and a second cross-sectional area across the second surface (54) of the first sidewall (52), where the first cross-sectional area is not equal to the second-cross sectional area. Each of the cooling channels (50) also includes a tapered portion extending between the first-cross sectional area and the second cross-sectional area.
