Abstract:
A battery module includes a housing configured to hold prismatic battery cells within a space defined by four interior walls of the housing. The housing includes a first interior wall that includes partitions (e.g., ribs) extending upwards from a bottom of the housing and a second interior wall that includes partitions extending upwards from the bottom of the housing. The first interior wall faces opposite the second interior wall. The partitions disposed on the first interior wall and the partitions disposed on the second interior wall define slots between adjacent partitions, where each of the slots increases in width between the adjacent partitions from the bottom of the housing upwards. Each of the slots is configured to retain one of the prismatic battery cells.
