Advanced power converters with real-time diagnostics for EV drivetrains, achieving >98% efficiency and >45 kW/kg. Enables rapid fault detection and lifetime assurance, enhancing the performance of heavy-duty electric vehicles.
The proposed solution focuses on developing ultra high performance power converters with integrated real-time health monitoring systems. These converters are designed to overcome existing limitations in electric vehicle (EV) drivetrains by providing a lightweight (>45 kW/kg) and highly efficient (>98%) energy transfer system. The integration of real-time diagnostics enhances fault detection, ensuring reliability and extending the lifespan of power electronics in heavy-duty EV applications.
The converters utilize cutting-edge switched-capacitor technology to achieve unprecedented efficiency and low total harmonic distortion (THD). The health monitoring system comprises a sensing front-end suitable for integration into power converters, capable of detecting degradation in semiconductor devices and passive components. Additionally, a digital engine interprets data, providing real-time and forecast health information, predicting lifespan, reliability, carbon impact, and recycling capabilities.
Currently at TRL 3, the technology is in the development phase, with ongoing validation using in-house facilities. Industry consultation ensures adherence to roadmaps and compliance, aiming for future advancements to higher readiness levels.
