Multiple cell integrated casings

Abstract

The disclosure provides a battery cell casing for holding a plurality of cell elements, each electrode structure in its own compartment. The disclosed casing eliminates the need for some individual cell walls and replaces them with shared wall partitions.

Description

technical field [0001] The present application relates generally to the field of batteries and battery systems, and in particular to batteries and battery systems that may be used in electric vehicles. Background technique [0002] In general, electric vehicles differ from conventional motor vehicles in that electric vehicles are at least partially propelled using one or more battery-powered electric motors. In contrast, conventional motor vehicles rely solely on an internal combustion engine to propel the vehicle. An electric vehicle may use an electric motor instead of or in addition to an internal combustion engine. [0003] Example electric vehicles include hybrid electric vehicles (HEV), plug-in hybrid electric vehicles (PHEV), fuel cell vehicles, fuel cell electric vehicles, and battery electric vehicles (BEV). A BEV includes an electric motor, where the energy source for the motor is a battery that is rechargeable from an external grid. A HEV includes an internal c...

Problems solved by technology

However, such arrays can be heavy and often suffer from thermal and pressure heterogeneity

Furthermore, individual battery cells within such arrays are susceptible to misalignment and uneven compressive forces, which can adversely affect electrical connections between individual cells and cause other problems
