Embodiment 1

[0031] like Figure 1~3 As shown, an embodiment of a battery pack frame is provided.

[0032] like figure 1 , figure 2 As shown, the battery group frame 10 of this example includes a battery spacer plate 11 , a bottom plate 14 , a front vertical plate 12 , a rear vertical plate 13 and an upper cover plate 15 . The battery separator 11 is a square plate. The bottom plate 14 , the front vertical plate 12 , the rear vertical plate 13 and the upper cover plate 15 respectively form a T-shaped structure perpendicular to the battery partition plate 11 and are distributed on four sides of the battery partition plate 11 . The end surface of the upper cover plate 15 is provided with a groove 151 recessed inwardly from the edge.

[0033] like figure 1 As shown, the rear portion of the left end face of the base plate 14 is provided with a splicing groove 16, and the left end face front of the base plate 14 is provided with a splicing boss 17, and the right end face of the base plate...

Embodiment 2

[0038] like Figure 4~6 As shown, another battery pack frame embodiment is provided.

[0039] like Figure 4 As shown, the difference between this example and Example 1 is that the front vertical plate 12 and the rear vertical plate 13 of this example are provided with side plate through holes 18 , and the battery partition plate 11 is provided with partition plate through holes 112 . This design increases the contact area between the battery and the air, and enhances the heat dissipation performance of the grouped battery modules.

[0040] like Figure 4 and Figure 5 As shown, the cable-holding groove 153 provided on the battery pack frame 10 of this example is composed of a plurality of elongated columns arranged at intervals, and circular protrusions are provided at the ends of the elongated columns. The cable slot 153 can arrange the battery information collection wire harness in an orderly manner, avoid messy wear and tear of the battery information collection wire h...

Abstract

The invention discloses a battery grouping framework including a battery spacing plate, a bottom plate, a front vertical plate, a rear vertical plate and an upper cover plate; the battery spacing plate is a square flat plate; the bottom plate, the front vertical plate, the rear vertical plate and the upper cover plate form vertical T-shaped structures with the battery spacing plate respectively and are distributed at four side faces of the battery spacing plate; the end face of the upper cover plate is provided with a groove sunken from the edge to the interior; the bottom plate and the upper cover plate are provided with splicing grooves and splicing bosses respectively. The voltage and capacity of a grouped battery module are changed by freely changing the number of battery monomers, the convenience of the battery grouping is increased, the battery information collection wiring harness arrangement is specified, the assembly process of the battery module is simplified, the battery grouping framework is suitable for large-scale production, and the cost of manufacturing of a battery system is effectively reduced. In addition, the connected grouped battery system has excellent heat dissipation performance.

Description

technical field [0001] The invention relates to the technical field of battery packs, in particular to a battery pack frame. Background technique [0002] Relying on the current battery production process and equipment level, there are still great difficulties in the production of ultra-large-capacity batteries. Therefore, the current battery systems used in electric vehicles and new energy storage equipment are mostly multiple small-capacity batteries connected in series and / or Or in parallel to form a large-capacity battery module, and then connect these battery modules in series and / or in parallel to form a battery system that meets people's needs. [0003] To meet sufficient power requirements in a limited space, the grouping technology of the battery system will greatly affect its manufacturing cost and service life. At present, there are various problems in the group design of battery systems in the industry, such as low modularization, low space utilization, and mess...
