[0002] In the field of new energy power batteries, direct cooling plate heating has become the mainstream cooling method. However, the performance of lithium iron phosphate batteries is poor in low temperature environments, and heating films are often required to improve their low temperature performance.

[0003] The heating film is usually attached to the bottom of the battery, but the direct cooling plate is very easy to form condensation inside the battery. When the condensation acts on the heating film, it will cause aging and corrosion, which will cause insulation and voltage failure of the heating film, thus affecting the normal operation of the heating film and even the vehicle. Therefore, we urgently need a heating film that can prevent condensation from soaking. Utility Model Content

[0007] By adopting the above-mentioned anti-condensation direct cooling plate heating film, when condensation appears on the direct cooling plate in the battery, it will move to the surface of the protective plate and control the heating wire to heat up. At this time, there is a heat source under the protective plate to evaporate the condensation water. At the same time, the raised and grooved parts on the protective plate can provide a good ventilation channel above the heating film to avoid water accumulation, and the heat conducting plate can transfer the heat emitted from the bottom of the battery to the surface of the heating film, thereby improving the heating efficiency of the heating film and ensuring the stability of the temperature around the heating film.

It is worth mentioning that the protrusions 41 and the grooves 42 can respectively cooperate with the heating film 1 and the battery to form a chamber, which has a preliminary heat gathering effect.

[0025] Specifically, the heating wire 2 is evenly laid in a zigzag shape in the heating film 1, so that the heating film 1 can dissipate heat more evenly.

[0026] As an optional embodiment, the bolt connector 3 includes a bolt hole 3a opened on the surface of the heating film 1, and a bolt 3b is threadedly connected to the bolt hole 3a. A through hole 3c is opened on the protective plate 4 to be plugged into the bolt 3b. When the protective plate 4 is installed on the surface of the heating film 1, the bolt 3b is inserted into the through hole 3c and the bolt hole 3a at the same time and rotated to complete the installation and fixation of the protective plate 4.

[0027] Reference Figure 2 As shown, a pressure-sensitive adhesive ring 7 is fixedly connected to the bottom surface of the heating film 1 , and the pressure-sensitive adhesive ring 7 can effectively prevent the heating film 1 from sliding or falling off during use, thereby ensuring the stability and safety of the heating film 1 .
