To realize the intelligent balance between the cells of the battery, it is necessary to place the intelligent balance circuit board. However, in the existing bridge structure, either a balanced circuit board is placed in each cell, or a balanced circuit board covering the entire battery slot is required. These two methods are difficult to implement, and the cost is relatively high, and the performance is relatively poor.

Contents of the invention

The technical problem to be solved by the utility model is to provide a storage battery bridge structure, which is convenient to realize the placement of a balanced circuit board, and has low cost and high performance.

In order to solve the above-mentioned existing technical problems, the utility model adopts the following scheme: the battery bridge structure includes a battery tank, a positive plate and a negative plate arranged in the battery tank, and a separator is arranged between the positive plate and the negative plate. The battery tank is provided with a positive bus bar corresponding to the positive plate, and the battery tank is also provided with a negative bus bar corresponding to the negative plate, and the positive bus bar is provided with a positive bridge pole. The negative bus bar is provided with a negative bridge pole, and a bridge is provided between the adjacent positive bridge pole and the negative bridge pole, and the positive bridge pole on the front positive bus bar and The negative bridge pole on the negative bus bar in the front section is set in the center of the battery tank close to the edge of the central plastic barrier, the positive bus bar and the negative bus bar in the rear section are provided with lead-out terminals at the side ends, and the positive bus bar in the middle section is provided with lead-out terminals. The poles of the positive span bridge and the poles of the negative span bridge on the negative busbar in the middle section are all arranged in the center. The cross-bridge and the intelligent balance circuit board are welded correspondingly for easy placement.

Preferably, an auxiliary terminal corresponding to the lead-out terminal is provided at the center of the positive bus bar and the negative bus bar at the rear section. Easy to place smart balance circuit board.

Beneficial effect:

The utility model adopts the above-mentioned technical scheme to provide a battery cross-bridge structure, and the middle cross-bridge pole and the bridge are arranged in the center of the busbar, which facilitates the placement of balanced circuit boards, and has low cost and high performance. At the same time, the area of the intelligent balance circuit board is reduced, and it is more convenient to place.
