As electric vehicles (EVs) become more powerful and feature-rich, power electronics—such as inverters, DC/DC converters, and onboard chargers—generate significant heat. Cooling plates, often integrated with liquid-cooling systems, are critical to maintaining optimal operating temperatures, ensuring efficiency, and prolonging component life.

According to Stratview Research, the EV power electronics cooling plates market size was US$ 1.2 billion in 2024 and is likely to grow at a strong CAGR of 10.7% in the long run to reach US$ 2.7 billion in 2031.
