In electric vehicles, drive batteries, electric motors, and power electronics all require effective thermal management. Silicone-based thermal interface materials are essential in this field because of their robustness and wide range of consistencies.
Recognizing the signs of the times, the automotive industry is working feverishly to develop electromobility. How to effectively dissipate the heat produced by the various components while the vehicle is moving and the battery is being charged is one obstacle.This kind of thermal management is especially important for the battery that provides the power.
The best performance from lithium-ion batteries can only be achieved. As a result, they must not overheat in order to guarantee acceptable performance and longevity. The power electronics and the electric motor also produce heat. Again, this thermal energy must be quickly and effectively dissipated in order to avoid failure or damage caused by heat.
Here, thermal interface materials, or TIMs, are crucial. They reduce the thermal transfer resistance because they bridge the distance that separates the assembly that needs to be controlled by temperature from the heat exchanger or heat sink. They improve the components’ thermal coupling as a result of this.
As car manufacturers develop electric vehicles for mass production, thermal interface materials are becoming increasingly attractive.
The EV On-board charger silicone thermal interface material accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
