Abstract

The invention relates to the technical field of electric cars, in particular to a battery module. The battery module comprises a plurality of cells, an electric core fixing plate, a positive electrodeconflux sheet and a negative electrode conflux sheet, wherein the positive electrode conflux sheet is fitted to the electric core fixing plate, and are fixed on the end surfaces of the positive electrodes of the plurality of cells, and the negative electrode conflux sheet is fixed on the end surfaces of the negative electrodes of the plurality of cells; cellular units for fixing the cells, corresponding to the quantity of the cells are arranged at the inner side of the electric core fixing plate; a plurality of support posts are arranged at the outer side of the electric core fixing plate; and the support posts are used for fixing the positive electrode ends of the cells in single battery module, and the positive electrode end and the negative electrode end of the corresponding cell in the serially connected battery module. The battery module has simple structure, and design and reasonable design, can effectively reduce the manufacturing cost and total quality of the battery module, can improve the energy density of the battery module, can ensure the safety and reliability of the battery module, and can improve the light weight level of the battery module.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a battery module. Background technique [0002] With the maturity and development of various technologies of electric vehicles, coupled with the advantages of environmental protection, conservation, subsidies, and tax reductions, electric vehicles have attracted more and more attention from consumers. Among them, the power battery is the core component of the electric vehicle. As the power source of the electric vehicle, its performance is directly related to the performance of the electric vehicle. To ensure that the electric vehicle has a certain mileage, the power battery loaded is composed of a large number of single The batteries are connected in series and parallel. Inside the power battery pack, each battery module is connected in series. Each module must ensure the firmness of the single battery installation. The traditional battery module can guarantee the saf...
