Designed in-house and built at the Cléon factory, the synchronous motor produces the same 88bhp as the unit in the ZOE, but integrating components, moving to air cooling and not using external cables has enabled Renault to reduce the size of the entire unit.

The junction box and Chameleon charger are contained within the Power Electronic Controller, in itself 25% smaller than current systems, while improved electronic management and a redesigned inverter improves charging speed and efficiency.

Renault says the EOLAB-sourced technology will appear in a production car during 2015.
