A battery module having a plurality of battery cells and a first housing element () and a second housing element () is disclosed. The housing elements together form an interior space () in which the plurality of battery cells is accommodated, and are each formed from a metal material, the first housing element () having a projection () and the second housing element () having an indentation (), the projection () engaging in the indentation (). On a side facing away from the interior space, the first housing element () has a first weld region () and the second housing element () has a second weld region (), the first weld region () and the second weld region () being connected to one another by welding.

Battery module

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 ().
