<p>The present invention relates to a voltage sensing circuit for a vehicle battery to sense voltages for a plurality of unit cells and a cell module assembly including the same. The voltage sensing circuit for a vehicle battery includes: sensing bus bars, when unit cells adjacent to each other among the unit cells are modularized by a pair, which are individually disposed between cell leads of the modularized one pair of the unit cells and individually bonded to the cell leads by laser welding so as to connect the cell leads by the one pair of unit cells; and wires having one end individually connected to the sensing bus bars in order to draw a current flowing into the sensing bus bars. According to the present invention, since a bonding method by laser welding is used instead of bonding by a connector, the shock resistance and the impact resistance of a vehicle battery may be improved.</p> |
