How to solve the heating problem of the battery pack?

In the context of lightweight power lithium-ion batteries, many OEMs or battery manufacturers have begun to consciously turn the metal materials of battery packs into non-metallic materials, but problems also follow. When the material changes from metal to non-metal material, some key electronic components such as battery, battery management system, etc. will be interfered by external signals. How to shield some unwanted signals has become a problem facing the company now . At the same time, with the higher the energy density of the battery, the heating of the battery pack becomes more and more serious when the battery is charged and discharged at a high rate. How to quickly and effectively release the heat has also become a problem that the company must solve. As the battery pack switches from metal to non-metal materials, it is first necessary to shield its own signal so that the signal does not interfere with other key components; at the same time, it is also necessary to ensure that external signals will not interfere with battery components. Lu Xingtao said: In response to the above problems, Henkel has developed electromagnetic shielding technology, which can be directly sprayed on the surface of non-metallic materials, which can effectively shield itself or the external electromagnetic radiation interference. At the same time, Henkel has also developed relevant technologies in response to the heating problem of the battery pack. Lu Xingtao said: The company has developed a variety of solutions for different needs in response to the heating problem of battery packs. The first is the elastic thermal conductive adhesive, which is characterized by relatively strong electrolyte resistance, and at the same time has a large compression set, can effectively absorb the volume expansion of the cell during operation, and has stable thermal conductivity. Secondly, Henkel Loctite's thermally conductive adhesive can replace traditional mechanical structure fixation, meet high-strength mechanical indicators, and effectively transfer the heat that occurs during battery operation, ensuring the safety of the battery pack. In addition, Henkel's thermal conductivity potting technology takes into account good process performance under the premise of satisfying thermal conductivity. Considering the large difference in thermal expansion coefficients of various substrates in new energy vehicles, Henkel's thermal conductivity potting products have excellent resistance Hot and cold shock. It can meet the application needs of some key components such as battery management systems, motors, car chargers and so on.
