All-new Megane E-TECH Electric: road-trip to the heart of innovations – Episode 4
Published on
Join Jean-Baptiste Nicolet, host of the TheiCollectionYouTube channel, as he takes us on a road-trip on board the All-new Renault Megane E-TECH Electric, journeying through a selection of innovative features that gave rise to a number of patents. In this fourth episode, we joined him for the last few kilometres of motorway heading to Deauville.
On this stretch of motorway, Jean-Baptiste focused on the car’s dynamic performance. He put the power of the 220 hp engine to the test and admitted that he was blown away by its instantaneous acceleration and driveability. He got in touch with Fabrice, the Head of Renault’s e-technology work unit, to find out how the engineers managed to make this compact hatchback a genuine road car that can deliver brisk linear acceleration over long periods of accelerator operation. Fabrice explained that the All-new Megane E-TECH Electric’s powertrain offers groundbreaking performance thanks to its oil cooling system, which features two patented innovations.
Electric motors must have an excellent cooling system in order to be efficient. We therefore worked with our colleagues in both Japan and Clon, France, to develop two patented innovations. The first of those patents covers the oil cooling system for our wound rotor synchronous motor. We fitted injectors in strategic places to splash the electric wound rotor motor while simultaneously cooling both the rotor and the stator. The second patented innovation covers a clever technique that enables us to harness the rotors momentum, using a ring gear system to accentuate stator cooling by projecting oil towards the heads.
Key to harnessing the power of the New Megane E-TECH Electric's engine on long motorway journeys, its cooling system is far from being the latest innovation uncovered by Jean-Baptiste. When he arrived in Deauville, he knew that he had not reached the end of his discoveries.
