The invention discloses an electric vehicle battery, which comprises a battery shell. The electric vehicle battery is characterized in that the inside of the battery shell is divided into six unit cells; 7 positive plates and 8 negative plates are arranged in each unit cell; the positive plates and the negative plates are stacked in a staggered manner; partition plates are arranged between the positive plates and the negative plates for isolation; the positive plates and the negative plates are connected with busbars; and eight busbars are located at the upper parts of barriers in the battery shell, are embedded into a cover of the battery shell, and are sealed with glue. By the storage battery series principle, positive and negative busbars of partial pole groups are combined, so that the ohm inner resistance of the battery is reduced; the high current discharge performance of the battery is improved; and the cost of the battery is reduced.
