High-Efficiency Power Converters for Heavy-Duty Electric Trucks and Trailers

transportTestedTRL 5

Imagine the electrical brain of a massive truck that manages power from the battery to the wheels. Current versions are often too bulky or waste too much energy. This work creates a smaller, smarter system using advanced materials that keep the truck running longer and cost less to maintain.

The business problem

What needed solving

Heavy-duty electric vehicles suffer from bulky, inefficient power converters that increase costs and reduce payload capacity. Current systems lack the reliability and thermal management needed for long-haul transport.

The solution

What was built

A high-efficiency Integrated Motor Drive (IMD) powertrain, including 1200V traction converters, active gate drivers, and digital twins for simulation.

Frequently asked

Quick answers

How does this affect the total cost of the vehicle?

The project aims to reduce costs by using a modular approach and disruptive topologies in power converters. Based on available project data, the goal is to make heavy-duty electrification more cost-effective.

Can this be scaled to industrial production?

Yes, the project focuses on modular power electronics and ecodesign to facilitate scalability across a wide range of heavy-duty vehicles.

What is the IP and licensing situation?

Based on available project data, non-confidential results are shared via Open Science, but specific exploitable results like the IMD Powertrain and digital twins are developed for commercial use.

Does this comply with EU emission regulations?

The project specifically targets zero-emission class N3 and O4 vehicles to help achieve EU efforts against climate change.

How is the system integrated into existing chassis?

The project uses Integrated Motor Drive (IMD) architectures to create compact solutions that reduce the overall size of the powertrain.

Consortium

Who built it

The consortium is heavily industry-driven with a 56% industry ratio, comprising 5 industrial partners and 1 SME across 6 countries. This strong commercial presence, balanced by 3 universities and 1 research center, suggests the project is focused on market application rather than pure theory.
