Technical Field

[0001] This utility model relates to the technical field of battery insulation, and in particular to an integrated battery insulation structure. Background Technology

[0002] In cold winters, lead-acid batteries are easily affected by low temperatures, making it difficult or even impossible to charge electric vehicles equipped with them, significantly reducing their driving range. Current technology typically uses an insulation box to keep the battery warm. However, when there are many batteries, the insulation box needs to be of a certain length to cover multiple cells, which not only fails to effectively insulate multiple cells but also affects the production cost and versatility of the insulation box. Therefore, improvements are needed. Summary of the Invention

[0003] This invention addresses the shortcomings of existing technologies, such as the need for insulation boxes of various sizes when insulating lead-acid batteries with different numbers of cells, which affects production costs and makes it inconvenient to insulate multiple lead-acid batteries. It provides a new integrated battery insulation structure.

[0013] Preferably, in the integrated battery insulation structure described above, the heating element is arranged in a circular pattern, and the heating element is composed of multiple heating wires connected in parallel, with the heating wires spaced apart along the height direction of the insulation box.

[0014] The heating element is arranged in a ring around the insulation box, which can better heat and keep the battery warm. Because the heating wires are connected in parallel, the failure of some heating wires will not affect the use of the remaining heating wires, thus improving the service life of the heating element.

Each insulation box 1 has interconnected sockets 2 on its front and rear sides. Each insulation box 1 contains a heating element 3, which is electrically connected to the sockets 2. The structure also includes a power plug 4 and an adapter 5. The power plug 4 is plugged into the socket 2 at one end of the insulation group 11, and the adapter 5 is plugged into adjacent sockets 2 on different insulation boxes 1. The power plug 4 is electrically connected to an external power source. The insulation boxes 1 are connected in series via the power plug 4, adapter 5, and sockets 2.

[0028] Preferably, a sealing plug 6 is also included, and the power plug 4 and the sealing plug 6 are inserted into the sockets 2 at both ends of the insulation row 11.

[0031] Preferably, the heating element 3 is arranged in a circular pattern, and the heating element 3 is composed of multiple heating wires connected in parallel, with the heating wires distributed at intervals along the height direction of the heat preservation box 1.

[0032] Preferably, the heat preservation box 1 includes an upper shell 13 and a base 14.
