Global strategic engineering and environmental consultancy Ricardo plc is presenting the early results of its research and development project to develop a scalable Electric Drive Unit (EDU) for future electric vehicles at the CTI’s 8th International Congress and Expo, September 24–25, 2019, in Shanghai, China.
The scalable EDU being developed by Ricardo is said to comprise a high-performance compact electric machine and power inverter, coupled to a multi-speed powershift transmission. In addition to offering a scalable solution for future electric vehicles (EVs), the unit is intended to provide state-of-the-art power and torque density, NVH performance and system efficiency.
Its design draws upon the results of the collaborative European research project EcoChamps. Features developed during the project include the use of hairpin electric machine winding, and shared cooling for the motor, transmission and inverter.
At CTI Symposium Shanghai, early results of this work will be revealed, together with the virtual product development processes used in the project – a subject on which Ricardo will give a separate presentation. Final results of the EDU development are expected to be revealed later this year.
“I am pleased that Ricardo is able to share the results of this advanced EV powertrain research with our Chinese automotive industry colleagues at Shanghai’s CTI Symposium,” commented Gary Tan, President, Ricardo Asia. “This work demonstrates how Ricardo can bring the latest ideas and research from our teams across the globe to deliver the advanced technologies for China’s new energy vehicles of tomorrow.
