Embodiment Construction
[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0039] It should be noted that if there is a directional indication (such as up, down, left, right, front, back, outside, inside...) in the embodiment of the present invention, the directional indication is only used to explain the direction in a certain posture ( As shown in the accompanying drawings), if the specific posture changes, the directional indication will also change accordingly.
[0040] In addition, if there are descriptions involving "f...

The invention discloses a power battery pack, which comprises a lower casing, a battery module and an upper casing assembly. Two crossbeams and multiple longitudinal beams are fixedly installed in the lower shell, and the multiple longitudinal beams are arranged at intervals between the two crossbeams along the length direction of the crossbeams to form a plurality of strip-shaped holes. The battery module includes a plurality of battery cells and a plurality of separators, and the plurality of battery cells are placed in a plurality of strip-shaped holes at intervals along the length direction of the longitudinal beam, and a separator is installed between two adjacent battery cells. The upper case assembly is covered above the battery module and fixedly connected with the lower case. The power battery pack provided by the present invention can not only completely fix the battery cells, but also when the power battery pack is subjected to a lateral collision, the lower case forms the first line of defense, and the longitudinal beam forms the second line of defense, which can greatly improve the performance of the power battery pack. Anti-side impact capability. In addition, the multi-row longitudinal beams can also avoid the short circuit in the battery cells caused by excessive deformation of the power battery pack at one time, thereby comprehensively improving the service life of the power battery pack.
Description
technical field [0001] The invention relates to the technical field of power batteries, in particular to a power battery pack. Background technique [0002] The structure of the traditional new energy power battery battery pack is as follows: a power battery is composed of multiple battery cells connected in series and parallel, and the battery cells are connected by welding electrical connection parts. Welding the same poles of the same poles to achieve parallel connection to form a series, the parallel area is then connected to multiple cells in parallel with different poles to form a series connection, and multiple series-connected areas form a modular module, which is mass-produced outside the battery pack Assemble, and then install the modules into the battery pack one by one, which is currently the most widely used battery pack grouping method. [0003] In order to reduce the process steps of battery pack assembly and reduce processing costs, a non-modular battery pac...
