A battery pack () includes a housing () and an array of electrochemical cells () disposed in the housing (). The housing () includes a container () and a lid () that closes an open end of the container (). The container () has a base (), a sidewall () that surrounds the base (), and a spring plate () disposed inside the sidewall () between the cells () and the sidewall (). The spring plate () is free standing within the container () and applies a spring force to the cell array that restrains the cells () along an axis normal to the surface of the spring plates (). The lid () includes inwardly-protruding pins () that further restrain the cells () within the housing ().

Battery pack including cell restraint

A battery pack includes a housing and electrochemical cells disposed in the housing. The housing includes a container and a lid that closes an open end of the container. The container has a base, an outer wall the surrounds the base, and a first and a second inner wall disposed inside the outer wall. The first inner wall extends between, and is fixed to, a first portion and a third portion of the outer wall, and is spaced apart from a second portion and a fourth portion of the outer wall. The second inner wall extends between the first portion and the third portion, and is disposed between the first inner wall and the fourth portion. The second inner wall is movable relative to the outer wall such that spacing of the second inner wall from the first inner wall can be changed.

Battery pack

A battery pack () includes a housing () and an array () of electrochemical cells () disposed in the housing (). The housing () includes a container () and a lid () that closes an open end of the container (). The container () has a base (), a sidewall () that surrounds the base (), and a spring plate () disposed inside the side wall () between the cells () and the sidewall ().

The invention relates to a housing () for accommodating a plurality of battery cells (), in particular lithium-ion battery cells, wherein the housing (), in particular a plastic housing, comprises a cooling device with an inlet point () and an outlet point () for an air stream () for cooling the battery cells (). In addition, the housing () is designed as a single piece together with the cooling device integrated in the housing (), and the cooling device additionally has spacers () for arranging all accommodated battery cells () with an intermediate space () for guiding air between the battery cells (), by which means an air channel () is provided for the air stream () between the battery cells (). The invention further relates to a battery pack () and to a motor vehicle comprising such a battery pack ().
