摘要:
Systems, methods, and other implementations described herein relate to a battery for use in a battery cell assembly that facilitates pack manufacturing. A method of manufacturing the battery cell assembly for the battery pack includes providing at least one battery cell in the battery cell assembly. The battery cell includes at least one prebent electrical tab. The method further includes operatively connecting a busbar to the prebent electrical tab on the battery cell, without substantially deforming the prebent electrical tab, whereby subsequent bending of the at least one prebent electrical tab is unnecessary.

An electrochemical storage device comprises a plurality of layer electrodes each including a first charged sector and a second charged sector. The plurality of layer electrodes are assembled with respect to each other such that the first charged sector of a first plate of the plurality of layer electrodes is laid below the second charged sector of a second plate of the plurality of layer electrodes located immediately above the first plate. The charges of the first charged sectors of the first and second plates have a first sign and the charges of the second charged sectors of the first and second plates have a second sign that is opposite the first sign. The device also comprises a separator sector located, and enabling ionic charge exchange, between the first charged sector of the first plate and the second charged sector of the second plate.

A battery cell assembly, a heat exchanger, and a method for manufacturing the heat exchanger are provided. The heat exchanger includes a rectangular-shaped sheet having first and second rectangular-shaped sheet portions coupled together at a bent edge such that the sheet portions are disposed proximate to one another. Outer edges of the first and second rectangular-shaped sheet portions are coupled together such that an interior region is formed between the first and second rectangular-shaped sheet portions. The bent edge has first and second apertures extending therethrough. The heat exchanger further includes a first inlet port disposed on the bent edge over the first aperture, and a second outlet port disposed on the bent edge over the second aperture, such that fluid can flow through the first inlet port and into the interior region and then through the outlet port.

A battery cell assembly is provided. The battery cell assembly includes a battery cell and a heat exchanger disposed adjacent the battery cell configured to cool the battery cell. The heat exchanger has an outer housing. The outer housing defines an interior region and first and second flow guide members. The first and second flow guide members define a serpentine flow path in the interior region. The first and second flow guide members are tilted generally upwardly in the interior region. The serpentine flow path extends from an inlet aperture in the outer housing to another flow path in the outer housing. The another flow path extends from the serpentine flow path to an outlet aperture. The another flow path has a smaller cross-sectional area than a cross-sectional area of each portion of the serpentine flow path such that air bubbles in fluid entering the inlet aperture are urged upwardly through the serpentine flow path and accelerated through the another flow path to exit the outer housing at the outlet aperture.

A battery module having a cooling manifold is provided. The battery module includes a plurality of battery cell assemblies having a plurality of heat exchangers. The battery module further includes the cooling manifold operably coupled to the plurality of battery cell assemblies. The cooling manifold has a manifold portion and a cover plate. The manifold portion has a peripheral wall, a rear wall coupled to the peripheral wall, and a flow diverter. The peripheral wall has a top portion with an inlet aperture extending therethrough. The rear wall has a plurality of outlet apertures extending therethrough. The cover plate is coupled to the peripheral wall opposite to the rear wall. The flow diverter extends from the rear wall and is disposed below the inlet aperture. The flow diverter is configured to receive fluid from the inlet aperture and to divert the fluid so that a substantially equal flow rate of the fluid is obtained through each outlet aperture of the plurality of outlet apertures to a respective heat exchanger of the plurality of heat exchanger for cooling the plurality of battery cell assemblies.
摘要:
A mounting system for a plurality of battery modules needed to form a battery pack includes a battery tray with a combination of fixed and detachable retainers that enable insertion/removal of individual battery modules from the battery pack, both during assembly of the battery pack and later in conjunction with service during its operation. The battery tray may be disposed on a base plate for added support, as well as integration of more than one battery tray and associated modules into a battery pack. A cover may be added to for additional support and protection of the battery modules. Where multiple battery trays are integrated on a base plate, the battery trays may be oriented on the base plate in different directions. The battery mounting system may be used in a motor vehicle or other applications that use a battery pack.
