Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicle manufacturing, in particular to an electric vehicle battery module that can be assembled efficiently. Background Art

[0002] New energy vehicles (i.e., electric vehicles) have quickly entered ordinary people's families, and people's pursuit of high cruising range is constantly increasing. And the high cruising range mainly depends on the increase in the number of batteries in the battery pack. The battery pack is formed by laser welding multiple batteries in multiple rows with multiple batteries in each row. The existing electric vehicle battery module includes multiple welding positions in multiple rows on a template. Each welding position can weld the positive electrode at the upper end of each battery to the negative electrode at the upper end of the adjacent battery through an aluminum row. A housing is provided at the lower part of the template. The housing is provided with a vertically arranged cylinder for placing batteries. An upper cover with holes on each welding position is provided at the upper part of the template. During assembly, the upper cover is first installed on the template, then a signal wire harness is installed on the upper cover. The signal wire harness is connected to each welding position through the holes on the upper cover. Finally, an aluminum row is installed on each welding position. Thus, due to the large number of batteries, the work of installing the signal wire harness and the aluminum row is cumbersome, the workload is large, and the production efficiency is low. Therefore, the processing cost of the battery pack is also continuously increasing.

[0003] In order not to transfer the high-cost battery to consumers, we must continuously improve the product assembly method, reduce the assembly steps, and improve the production efficiency to reduce the processing cost. Summary of the Utility Model

[0004] The problem to be solved by the utility model is to provide an electric vehicle battery module that can be assembled efficiently, so as to solve the problems of complex assembly, low assembly efficiency, and high processing cost of the existing electric vehicle battery module.

An upper cover with holes on each welding position is provided at the upper part of the template. It further includes an aluminum row for welding the positive electrode at the upper end of each battery to the negative electrode at the upper end of the adjacent battery, and a signal wire harness. An integrated plastic suction box is provided on the upper cover. The signal wire harness is arranged at corresponding positions of the integrated plastic suction box and each welding position.

[0006] To solve the above problems, the technical solution of the present utility model may also be: including multiple rows of multiple welding die positions on the template, a housing is provided below the template, the housing is provided with a vertically arranged cylinder for placing batteries, an upper cover with holes on each welding die position is provided above the template, and it further includes an aluminum row for welding the positive electrode at the upper end of each battery to the negative electrode at the upper end of the adjacent battery, a signal wire harness. An integrated plastic suction box is provided on the upper cover, and the aluminum row is arranged at the corresponding position of each welding die position of the integrated plastic suction box.

[0007] To solve the above problems, the technical solution of the present utility model may also be: including multiple rows of multiple welding die positions on the template, a housing is provided below the template, the housing is provided with a vertically arranged cylinder for placing batteries, an upper cover with holes on each welding die position is provided above the template, and it further includes an aluminum row for welding the positive electrode at the upper end of each battery to the negative electrode at the upper end of the adjacent battery, a signal wire harness. An integrated plastic suction box is provided on the upper cover, and both the aluminum row and the signal wire harness are arranged at the corresponding position of each welding die position of the integrated plastic suction box.

[0009] Due to the adoption of the above technical solution, the present utility model has the following beneficial effects compared with the prior art:

[0010] This highly efficient assemblable electric vehicle battery module integrates all signal wire harnesses and aluminum rows on the integrated plastic suction box, and then installs them on the upper cover. The installation of the signal wire harness and the aluminum row can be completed by one-step assembly process. And because numerous signal wire harnesses and aluminum rows are already in place on the integrated plastic suction box, when installing the integrated plastic suction box, only one signal wire harness or aluminum row needs to be aligned, and the installation of numerous signal wire harnesses and aluminum rows can be completed by one-time positioning, greatly improving the assembly efficiency, reducing the manufacturing cost of the battery pack, reducing the cost for consumers, and enabling the rapid popularization and promotion of new energy vehicles.
