[0027] Example 2:

[0028] Combine Figure 5-Figure 7 As shown, based on the embodiment 1, the cold-resistant protection mechanism 100 includes a first protective cover 110 and a second protective cover 120 arranged on both sides of a plurality of lithium batteries 500 in a group.

As the heating plate 183 releases heat, the heat energy is directly transported through the main pads 181 and the auxiliary pads 182, so that multiple lithium batteries 500 are covered under the guidance of circulating airflow, ensuring that the grouped batteries are in a constant temperature state in a low temperature environment, avoiding damage to the batteries due to instantaneous excessive heating.

[0037] Example 4:

[0038] Combine Figure 6-Figure 12 As shown, based on embodiment 1, the combined stabilization mechanism 400 includes two cross beams 410; The crossbeam 410 is provided with evenly distributed circular washers, and the circular washers are provided with bolts 420 adapted to the threaded holes; Multiple uniformly distributed reinforcing ribs 430 are movably installed between the two cross beams 410; The reinforcing rib rod 430 is provided with a plurality of evenly distributed limiting washers.

[0040] The working principle and use process of the present invention: The low temperature resistance of lithium batteries is divided into: charging preheating, optimizing the electrolyte, improving the positive and negative electrode profiles, and external heating; Different from the improvement of the lithium battery body, when the lithium batteries are grouped, the densely distributed lithium batteries are heated by the above-mentioned method other than external heating, which will cause the internal temperature of the grouped lithium battery module to rise too much, thereby reducing the service life of the lithium battery. At the same time, once the lithium battery group is overly concentrated, the concentrated heating will cause the temperature in the closed environment to rise instantly, which may cause certain safety hazards in serious cases. This device innovates based on the existing lithium battery grouping method. By evenly distributing multiple groups of pressure-bearing and venting components 310 in the gaps between the stacked lithium batteries, the four arc surfaces of a single group of pressure-bearing and venting components 310 provide effective protective support for the four adjacent lithium batteries, preventing the lithium batteries from being too concentrated and causing an instantaneous temperature increase. When the evenly distributed lithium batteries 500 generate heat during charging and discharging, the heat energy instantly released by the four adjacent lithium batteries 500 is input into the four first pressing blocks 316 in the cross-shaped structure. The exhaust chassis 240 in operation exhausts the heat outward through the multiple drainage pipes 230. The multiple first air pipes 314, second air pipes 324, and third air pipes 334 are used to cyclically release the heat energy in the enclosed space, thereby maintaining a constant temperature for the lithium batteries 500. When the external ambient temperature is low, by connecting the input terminal 184 and the output terminal 185 to the battery group circuit, the two heating plates 183 are used to quickly heat up the multiple lithium batteries 500 when they are charging and discharging. When the heat energy released by the input terminal 184 and the output terminal 185 rises to a rated value, the input terminal 184 and the output terminal 185 are powered off, so that the two heating plates 183 that are releasing heat release the heat energy into the annular cavity formed by the first protective cover 110, the second protective cover 120, the first baffle 130 and the second baffle 140, and cooperate with the drainage mechanism 200 to exhaust the heat outward, so that the hot air flow is finally input into the interior along the multiple first air pipes 314, the second air pipes 324 and the third air pipes 334, thereby providing constant temperature protection for the lithium batteries 500. This can prevent temperature imbalance in the battery group while also providing preheating protection for the battery, thereby improving the resistance of the lithium battery group 500 to external low temperatures.

[0041] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
