Problems solved by technology
[0002] In the environment of environmental pollution and energy shortage, the development of new energy is the general trend. At present, the energy saving and emission reduction of vehicles is also very important. New energy vehicles, especially electric vehicles, are an important direction for future automobile development. There are still certain gaps compared with traditional fuel vehicles in terms of cruising range and safety performance, which restrict the development of electric vehicles. Therefore, the current research on battery capacity and safety is an important topic for electric vehicle research. , while improving the capacity of a single battery module, it is also an important method to improve the mileage of electric vehicles by connecting multiple battery modules in series and parallel to form a multi-layer battery module structure. The battery modules of electric vehicles are usually Arranged on the target position such as the chassis of the car, in the related technology, the stability of the battery module is poor, and there is a large potential safety hazard

The embodiment of the invention discloses a multi-layer battery module structure and an automobile, and relates to the technical field of electric automobile batteries. According to the multilayer battery module structure, the stability of the battery module can be improved, so that the safety of the battery module is improved. The multilayer battery module comprises a first fastener and a plurality of battery modules, the plurality of battery modules are stacked along a first direction, each battery module is provided with a first through hole along the first direction, and the first through holes on the plurality of battery modules are aligned along the first direction; the first fastener sequentially penetrates through the first through holes in the plurality of battery modules along the first direction, and the end part of the first fastener extends out of the battery modules, so that the plurality of battery modules are fixed at a target position. The multi-layer battery module structure provided by the embodiment of the invention is used for fixing the battery module.
Description
Technical field [0001] Embodiments of the present application relate to the field of electric vehicle battery technology, in particular to a multilayer battery module structure and automobiles. Background [0002] In the environment of environmental pollution and energy shortage, the development of new energy is the trend of the times, at present, the energy saving and emission reduction of vehicles is also very important, new energy vehicles, especially electric vehicles are an important direction for the development of future automobiles, due to the limitations of electric vehicles in battery technology, there is a certain gap in terms of mileage, safety performance, etc. Compared with traditional fuel vehicles, which restricts the development of electric vehicles, so the current research on battery capacity and safety is an important topic for electric vehicle research. While improving the capacity of a single battery module, the multi-layer battery module structure is also an...
