Battery system

A battery system for holding battery cells to form a motor vehicle battery, comprising:

• a metallic housing;
• a plurality of system components configured to fasten and contact the battery cells in the metallic housing;
• and
• a foam body held in the metallic housing configured to displace air volume, wherein:
• the foam body comprises a recess configured to receive a system component from the plurality of system components and the foam body comprises a fire-retardant material,
• the foam body is connected to a portion of the metallic housing and is configured to dampen vibration,
• the foam body contacts the portion of the metallic housing only in selected sections that enable resonance frequencies to be shifted,
• the recess is part of a first foam body module,
• the foam body further comprises a second foam body module comprising a second recess configured to receive a second system component from the plurality of system components,
• the first foam body module is arranged in a middle portion of the portion of the metallic housing,
• the second foam body module is arranged in marginal regions of the portion of the metallic housing, and
• a mass of the first foam body module is heavier than a mass of the second foam body module.
