Embodiment Construction

[0033] The term "xEV" is defined herein to include all vehicles, or any variation or combination thereof, that use electric power for all or a portion of their vehicle propulsion. As understood by those skilled in the art, a hybrid electric vehicle (HEV) combines an internal combustion engine propulsion system with a battery powered electric propulsion system.

[0034] The term HEV can include any variation of a hybrid electric vehicle, such as micro-hybrid and mild-hybrid systems, which deactivate the internal combustion engine when the vehicle is idling and use the battery system to continue powering the air conditioning unit, radio or other electronic components, And start the engine by pedaling when needing to propel. A mild hybrid system may apply some degree of power assist to the internal combustion engine, while a micro hybrid system may provide no power assist to the internal combustion engine.

[0035] A plug-in electric vehicle (PEV) is any vehicle that can be char...

Abstract

The present application discloses a battery pack comprising: a battery comprising at least one battery cell, a connector, and a heat exchanger device; and a battery housing, the battery housing comprising: a bottom housing comprising at least a base and an upstanding peripheral wall, the bottom housing being adapted to receive a battery; a cover adapted to close the bottom housing; and fixing means adapted to hold the cover on the bottom housing in order to close the battery pack housing, characterized in that the cover comprises at least one projection positioned for pressing the battery assembly towards the center of the module, in which the battery is housed within the bottom housing and the cover covers the bottom housing, and the battery is held in the battery shell through a fixing device, and is adjacent to the wall of the bottom shell and the battery.

Description

technical field [0001] The invention relates to a battery pack, in particular to a battery pack housing and a battery assembly, in particular to a battery pack for electric vehicles. Background technique [0002] A common design for battery packs used in the automotive industry is as follows: pouch cells are stacked alternately together with heat exchangers on two threaded rods that are screwed into end plates. Another end plate is added at the end of the stack and bolted in for compression. [0003] This compressive force is needed on the battery cells. In fact, compressive force is required to balance the 5-10% volume expansion of the battery during charging and aging. Without this compressive force, the life of the battery module would be shorter. [0004] Additionally, the automotive industry is actively looking for a new generation of batteries that can extend autonomous range. To achieve this goal, the criterion is to increase the energy density. [0005] One way ...
