Problems solved by technology
Metal battery boxes have the disadvantages of complex structure, many processes, poor consistency, and heavy weight
[0003] Therefore, composite material battery boxes have appeared on the market, and the complete composite material battery box has the disadvantage of low rigidity
[0004] In order to improve the rigidity of the composite battery box, a metal frame is installed at the bottom of the lower box of the composite battery box. Due to the increase of the metal frame, although the rigidity will be increased, the weight of the battery box will also be increased.
For the vehicle, it will increase the weight of the vehicle, resulting in greater energy consumption

The application relates to the field of production techniques of lithium ion batteries, in particular to a lower box body and a battery box including the lower box body. The lower box body comprises a shell and a reinforcing and connecting structure, wherein the reinforcing and connecting structure comprises a reinforcing and connecting component; the shell is enclosed by a side wall and a side wall; further, a cavity is arranged inside the shell; the shell is provided with a connecting piece through hole; the connecting piece through hole is communicated with the cavity; the reinforcing and connecting component comprises a connecting piece, a reinforcing member and a filling structure; the reinforcing member is arranged in the cavity; the reinforcing member is provided with a connecting hole; the connecting piece is connected with the connecting hole; the filling structure is used for filling a residual space of the cavity. The battery box comprises an upper cover, a battery pack and the lower box body, wherein the battery pack is arranged in the lower box body; further, the battery pack is fixed with the lower box body; the upper cover covers the lower box body; further, the upper cover is fixed with the lower box body. By using the lower box body and the battery box including the lower box body, on one hand, the strength and the rigidity of the lower box body of the battery box can be guaranteed, and on the other hand, the weight of the battery box can be lightened, and energy density is improved.
Description
technical field [0001] The present application relates to the technical field of lithium ion battery production, in particular to a lower box and a battery box including the lower box. Background technique [0002] Nowadays, due to rising oil prices and less and less resources, electric vehicles have become an important development direction of the automotive industry. However, to install a large number of power batteries on electric vehicles, it is necessary to make boxes to install these power batteries, and the power battery boxes currently used in the automotive industry are generally made of metal materials. Metal battery boxes have the disadvantages of complex structure, many processes, poor consistency, and heavy weight. [0003] Therefore, composite material battery boxes have appeared on the market, and complete composite material battery boxes have the disadvantage of low rigidity. [0004] In order to improve the rigidity of the composite material battery box, a...
