Advanced Insulation Materials for EV Powertrains

Project Overview

Electric vehicles (EVs) rely on high-voltage powertrains to deliver the performance and efficiency demanded by modern consumers. These powertrains must operate reliably under extreme conditions, including high temperatures and fluctuating voltages. Insulation materials are critical to ensuring the safety and functionality of these systems, especially as voltage requirements increase to support faster charging and improved energy efficiency.

The client, a global leader in EV manufacturing, sought advanced insulation materials capable of withstanding high voltages and extreme temperatures while integrating seamlessly into their existing production processes. The challenge was to find materials that not only met these technical requirements but also optimized production costs and scalability.

The Problem

Challenges in High-Voltage Powertrain Development
