Accumulator module having optimized heat dissipation

An accumulator module (10), comprising:

• a metallic housing (12) comprising four sides enclosing a cavity;
• at least one carrier (18) that is placed in the interior of the cavity of the metallic housing (12) and is fitted with a plurality of accumulator cells (14) each comprising a free end face;
• and
• a plurality of evenly spaced cell connectors (16) oriented in parallel with one another,
• wherein:
• each accumulator cell (14) in the carrier (18) is electrically contacted on only one side and the at least one carrier (18) fitted with accumulator cells (14) is placed in the interior of the cavity of the metallic housing (12) in a form that thermally couples the free end faces of the accumulator cells (14) to the metallic housing (12), and each accumulator cell (14) is individually axially resiliently mounted in the carrier (18),
• each cell connector (16) has an elongated body that electrically conductively contacts the end-face contacts (28) of a plurality of accumulator cells (14) in a first group to the lateral surfaces (30) of a plurality of other accumulator cells (14) in a second group, and
• each cell connector (16) comprises a plurality of contact sections (40, 42, 44) each comprising at least one contact tongue (46) contacting the end-face contact (28) of a corresponding accumulator cell (14) in the first group and at least one contact tab (48) contacting the lateral surface (30) of a corresponding accumulator cell (14) in the second group,
• the plurality of contact sections (40, 42, 44) of the cell connector (16), each including the tongue (46) and the contact tab (48), are in one piece,
• each accumulator cell (14) in the first group is conductively contacted by two, separate, cell connectors (16), and
• the end-face contact (28) of each accumulator cell (14) in the first group is conductively contacted by a corresponding contact tongue (46) of one of the two cell connectors (16), and the lateral surface (30) of each accumulator cell (14) in the same first group is conductively contacted by a corresponding contact tab (48) of another one of the two cell connectors (16).
