Detailed Description

In the description of the present invention, it is to be understood that the terms "one end", "the other end", "outside", "upper", "inside", "horizontal", "coaxial", "central", "end", "length", "outer end", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are used only for convenience in describing the present invention and for simplicity in description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, should not be construed as limiting the present invention.

The utility model will be further explained with reference to the drawings.

As shown in fig. 1-3, a battery system suitable for low temperature environment, includes box subassembly and sets up battery module 1 in the box subassembly, the box subassembly is the cuboid structure, lays heat preservation thermal insulation material layer 2 on six faces of its inner wall respectively, still set up in the box subassembly and be used for carrying out dry package 9 inside the box subassembly. Wherein, heat preservation thermal insulation material layer 2 can play the effect that keeps warm and separate the temperature, avoids outside low temperature to influence inside the battery system, and dry package 9 contains the drier, can absorb the inside moisture of battery system, avoids the steam condensation that low temperature caused.

Referring to fig. 3, the box assembly includes a lower box 3 and an upper box cover 4 detachably connected to the lower box, and a sealing rubber strip 5 is disposed between the lower box 3 and the upper box cover 4. The bottom of the upper box cover 4 is provided with a circle of first surrounding edge 400, the top of the lower box body 3 is provided with a circle of second surrounding edge 300, and the sealing rubber strip 5 is of an annular structure and is clamped between the first surrounding edge 400 and the second surrounding edge 300. The sealing rubber strip 5 is preferably a silicone strip.

Referring to fig. 2, an interlayer 301 is arranged at the bottom of the lower box body 3, a plurality of partition bars 8 are arranged in the interlayer 301, and the battery module 1 is supported on the bottom of the lower box body 3, so that the battery module 1 is most easily conducted with low temperature, and the battery module is influenced, therefore, the bottom of the lower box body 3 is designed into an interlayer 301 structure, and the interlayer 301 is combined with the heat-insulating material layer 2, so that the heat-insulating effect is further enhanced.

With reference to fig. 2, a mounting seat 6 for fixing the drying bag 9 is disposed inside the box assembly, and the mounting seat 6 is preferably disposed on the heat insulating material layer 2 corresponding to the interlayer 301.
