Output electrode assembly and battery module

A battery module, comprising a plurality of batteries and an output electrode assembly, wherein the output electrode assembly is disposed above the plurality of batteries, the output electrode assembly comprising:

• a circuit board;
• a connector, disposed at a first end of the circuit board in a longitudinal direction of the output electrode assembly, wherein the connector is electrically connected to the circuit board and serves as a first voltage interface of the battery module, and the first end of the circuit board has a first bending portion, a transition portion, and a second bending portion, which forms a U-shaped structure together with the transition portion and the first bending portion, and the connector is located on one side of the second bending portion in the longitudinal direction;
• a reinforcing plate disposed between the second bending portion and the first bending portion;
• an output electrode connecting sheet, spaced apart from the connector in a transverse direction of the output electrode assembly that is perpendicular to the longitudinal direction, wherein the output electrode connecting sheet serves as a second voltage interface of the battery module;
• and
• a fastening base, having a supporting portion supporting the circuit board, a partition wall located between the output electrode connecting sheet and the connector, the partition wall extending in the longitudinal direction of the output electrode assembly and having a thickness direction in the transverse direction of the output electrode assembly that is perpendicular to the longitudinal direction, and a transitional connection wall connecting the partition wall to the supporting portion;
• the fastening base further including a first mounting portion formed on and including one side of the partition wall in the thickness direction of the partition wall, wherein the connector is fixedly mounted to the first mounting portion;
• and
• the fastening base further including a second mounting portion formed on and including the other side of the partition wall in the thickness direction of the partition wall, wherein the output electrode connecting sheet is fixedly mounted to the second mounting portion.
