[0002] With the development of new energy vehicles, there are more and more innovations in new energy vehicle batteries. New energy vehicle batteries are new types of car batteries that use new energy technology to reduce "greenhouse gas" emission pollution. They vary slightly with the types of new energy vehicles. Current new energy vehicle batteries are generally equipped with corresponding battery boxes for protection. Existing new energy battery boxes are usually in an integrated fixed structure during use, which is not convenient for subsequent battery maintenance; existing new energy vehicle battery boxes all have holes in the wall for heat dissipation, which often easily accumulates a lot of heat, and the heat is not easy to dissipate. When the heat accumulates and is difficult to dissipate, it will affect the safety of the battery; therefore, we have launched a new energy battery box that is convenient for heat dissipation.

[0025] In this embodiment, the main device 8 includes a battery pack 82, and a plurality of battery packs 82 are provided. The outer surfaces of the battery packs 82 are commonly fixedly connected with a connecting frame 83, and three connecting frames 83 are provided. The inner sides of the connecting frames 83 are commonly clamped with a thermal conductive silicone sheet 81, and the battery pack 82 is placed on the upper end of the placement net 7; the thermal conductive silicone sheet 81 has a serpentine structure, and the three connecting frames 83 are distributed equidistantly in the horizontal direction; the thermal conductive silicone sheet 81 has a serpentine structure so that it surrounds the outside of the battery pack 82. The thermal conductive silicone sheet 81 has good insulation and high resilience toughness, which can effectively avoid friction damage between the battery packs 82. The battery pack 82 is placed on the upper end of the placement net 7, which is beneficial to the heat dissipation at the bottom of the battery pack 82.

[0026] In this embodiment, the connecting device 2 includes a shell 21, and a plurality of ventilation grooves 22 are opened around the outer side of the shell 21.
