Novel power battery module structure

Abstract

The invention provides a novel power battery module structure. The novel power battery module structure comprises an outer cover plate, end plates, a bottom plate and a cell-BLOCK framework; the outercover plate comprises a top plate and side plates; the end plates are arranged at the two ends of the outer cover plate, and the end plates are used as fixed parts of the module; the outer cover plate and the end plates cover the bottom plate; the cell-BLOCK framework is arranged on the bottom plate and positioned in a framework which is formed by the outer cover plate and the end plates in a surrounding manner; the cell-BLOCK framework comprises a plurality of built-in single cells arranged side by side and a BLOCK framework; end copper plate assemblies are arranged at the two ends of the single cells; external ends are arranged on the end copper plate assemblies; the external ends are arranged at the two ends of the single cells to be used as end connectors of positive electrodes and negative electrodes; inner protection plates are arranged between the end copper plate assemblies and the end plates; and protection caps are arranged outside wiring bases on the upper parts of the external ends. By virtue of the novel power battery module structure, the cell duty ratio is improved, the module cost is lowered, and the module university is improved; and meanwhile, the module can be assembled simply, the module weight is lowered, and automatic production requirement can be satisfied.

Description

technical field [0001] The invention belongs to the technical field of battery systems in the new energy automobile industry, and in particular relates to a new power battery module structure. Background technique [0002] With the increasing popularity of electric vehicles, the requirements for the mileage and price of electric vehicles have also been widely concerned. As an important part of electric vehicles, power batteries are imperative to study their structures. [0003] The electrical connection inside the module requires a large number of copper bars, bolts, nuts and wire harnesses, which is not only difficult to assemble, but also has low reliability. Therefore, optimizing the design of the electrical connection of the module can reduce the weight of the module and improve the quality of the module. group reliability.
