How to choose the thermal conductive silicone sheet for automobile battery pack?
2024-09-30
At present, with the rapid development of new energy vehicles, the lightweight requirement of new energy vehicles has become a trend requirement. As one of the components that account for a large proportion in the battery pack of new energy vehicles, the lightweight requirement of thermal conductive silicone film has become more important. Today, the author will continue to discuss with you how to choose thermal conductive silicone film for battery packs of new energy vehicles. Today's discussion on thermal conductive silicone sheets is brand-new and can help customers to select the key indicators of thermal conductive silicone sheets for new energy vehicle battery packs more accurately and quickly in thermal conductive silicone sheets with serious homogenization.
The correct selection method of thermal conductive silicone sheet for battery pack of new energy vehicles. After the thermal conductive silicone sheet meets the service life of new energy vehicles for more than 10 years and reliability requirements, the hardness and softness of the thermal conductive silicone sheet are very important. Because the working environment of new energy vehicles causes the entire thermal conductive silicone sheet to work in a continuous vibration environment, in order to ensure that the thermal conductive silicone sheet can consistently maintain a perfect fit to the battery pack shell or battery cell under the working condition, it is necessary to choose a thermal conductive silicone film with low hardness and good softness. Only by meeting these two indicators can it be ensured that the thermal conductive silicone film fits tightly in the battery of a new energy vehicle, and the battery of a new energy vehicle can effectively transfer heat all the time. And play a role in shock absorption and buffering.
How to choose a new energy vehicle battery pack thermal conductive silicone sheet? Tell you one of the most easy to judge and the most simple and practical is the most critical indicator-the density of thermal conductive silicone sheet. As we all know, with the rapid development of new energy vehicles, the lightweight requirement of new energy vehicles has become a trend requirement. As one of the components with a large proportion in the battery pack of new energy vehicles, the lightweight requirement of thermal conductive silicone sheet has become more important. As we all know, the density of thermal conductive silicone sheet is usually relatively large, generally, it will exceed 2.5g/cm3 (this is the regular density of thermal conductive silicone sheets used in battery packs of new energy vehicles in the industry), which exceeds the density of other structural parts of battery packs. In addition, it is extremely urgent to reduce the density of thermal conductive silicone sheets for battery packs of new energy vehicles and realize lightweight. This has also become a hard index for the new energy vehicle industry to select thermal conductive silicone sheets.
