Embodiment Construction

[0035] The present invention generally relates to securing battery arrays within the housing of a battery pack. The fixation techniques disclosed herein utilize relatively little packaging space. Fixing can be done from a location outside the open area of ​​the housing. That is, it can be secured from a location external to the battery pack.

[0036] Such as figure 1 As shown, a hybrid electric vehicle (HEV) powertrain 10 includes a battery pack 14 including a housing 16 housing a plurality of battery arrays 18 . The powertrain 10 also includes an internal combustion engine 20 , a motor 22 and a generator 24 . Motor 22 and generator 24 are types of electric machines. Motor 22 and generator 24 may be separate or in the form of a combined motor-generator.

[0037] In this embodiment, powertrain 10 is a power split powertrain employing a first drive system and a second drive system. The first and second drive systems generate torque to drive one or more sets of vehicle driv...

Abstract

An exemplary battery assembly includes an endplate of a battery array, and an enclosure wall secured directly to the endplate from outside an open area of a battery pack enclosure. An exemplary method of securing a battery array includes positioning a battery array within an open area of an enclosure and, from a position outside the open area, securing an endplate of a battery array directly to a wall of a battery pack enclosure.

Description

technical field [0001] The present invention relates generally to securing battery arrays and, more particularly, to securing battery arrays within battery pack housings. Background technique [0002] Electric vehicles differ from conventional motor vehicles in that electric vehicles are selectively propelled using one or more electric machines powered by traction batteries. The electric machine can replace the internal combustion engine or additionally drive the electric vehicle. Example electric vehicles include hybrid electric vehicles (HEV), plug-in hybrid electric vehicles (PHEV), fuel cell vehicles (FCV), and battery electric vehicles (BEV). [0003] Traction batteries for electric vehicles may include a battery pack having multiple arrays of individual cells within a pack housing. Each of the battery arrays typically includes a plurality of individual battery cells sandwiched between end plates. Many of the techniques used to secure battery arrays within battery pa...
