Electrochemical energy storage module and vehicle

An electrochemical energy storage module, comprising at least one energy storage cell and at least one bridging device which is electrically connected in parallel with the at least one energy storage cell, wherein the at least one bridging device comprises:

• a first current conductor having at least one bridging point having a bridging point cross-section;
• a second current conductor, which is spaced apart from the first current conductor by a gap;
• a bridging switch for establishing a first partial electrical connection between the first current conductor and the second current conductor;
• and
• a bridging material arranged in the region of the bridging point,
• wherein the first and/or the second current conductor have a plurality of bridging points having different bridging point cross-sections, in the region of which bridging material is respectively arranged, wherein the bridging point cross-sections and/or the bridging material in the region of the respective bridging point are/is configured in such a way that the bridging material in the region of the respective bridging point melts as a consequence of heating of the respective bridging point caused by an electric current that flows through the respective bridging point cross-section after the establishment of one or a plurality of partial electrical connections between the first current conductor and the second current conductor in the region of bridging points having a smaller bridging point cross-section, and in the process establishes a further partial electrical connection between the first current conductor and the second current conductor, and wherein the bridging material at another bridging point having a larger or next larger bridging point cross-section melts on account of the current flow increased by the partial connection established previously and establishes the further partial electrical connection such that a cascade-like establishment of the partial electrical connections can be achieved.
