Case Study: Efficient Phase Change Material for New Energy Vehicle Inverters

As a critical component of NEVs, the inverter converts the direct current (DC) from the vehicle’s battery to alternating current (AC) to drive the electric motor. The performance of the inverter is directly related to the motor’s power output and the vehicle’s endurance. Inverters generate heat due to power losses in electronic components like transistors, diodes, and capacitors. Modern inverters often operate at high power densities and frequencies, increasing the heat that must be dissipated. Excessive heat can reduce performance and efficiency, cause component failure, or raise safety concerns.

One of Honeywell’s customers – a leading manufacturer of propulsion solutions for Electric Vehicles- faced the heat dissipation problem caused by the inverter and urgently needed a heat dissipation material with higher thermal conductivity, higher reliability, and thinner volume. After diligently evaluating various options, they adopted Honeywell’s Phase Change Material (PCM)  thermal interface solution for its excellent thermal conductivity, high reliability, and suitability for thin gaps. Since its adoption, the Honeywell PCM solution has significantly improved the heat dissipation performance of our customers' new energy vehicle inverters, helping them respond to industry challenges effectively.
