Abstract
Disclosed herein is a battery module having a plurality of unit cells that can be charged and discharged, the battery module including busbars for electrically interconnecting the unit cells, ring terminals connected to electrical connection portions of the unit cells for measuring voltages of the unit cells, and a busbar mounting member mounted at an outer surface of the battery module corresponding to the electrical connection portions of the unit cells, the busbar mounting member including ring terminal guides for preventing rotation of the ring terminals.
Claims18
A battery module having a plurality of unit cells that can be charged and discharged, the battery module comprising:
- busbars for electrically interconnecting the unit cells;
- ring terminals connected to electrical connection portions of the unit cells for measuring voltages of the unit cells;
- and
- a busbar mounting member mounted at an outer surface of the battery module corresponding to the electrical connection portions of the unit cells, the busbar mounting member comprising ring terminal guides for preventing rotation of the ring terminals,
- wherein each of the ring terminals comprises a terminal end coupled to a corresponding one of series connection portions of the unit cells and a terminal wire connected to the terminal end, and each of the ring terminal guides fixes the terminal wire at a correct position for restraining rotation of the terminal end,
- wherein each of the ring terminal guides is configured to have a protruding structure for supporting one side or opposite sides of the terminal wire,
- wherein the busbar mounting member further includes a hook for fixing the terminal wire, and
- wherein the hook is formed at the one end of each of the ring terminal guides such that the hook protrudes upward therefrom.
