Chameleon, an innovation from Renault to develop electric vehicle use

The Chameleon charger is a solution developed by Renault to fit electric cars with a powerful onboard charger at limited cost. The basic idea is to "divert" the motor and inverter from their role in providing traction so that they also contribute to the charging of the battery. The Junction Box, a new sub-system developed by Renault, manages the charging process, changes the alternating current to direct current and communicates with the charging station. The Chameleon charger's Junction Box is only slightly bigger and heavier than the 3V charger found on most other electric vehicles on the market but, thanks to the use of the inverter and motor windings, charging power can reach 43 kW.

Fitted under the bonnet of ZOE, the Chameleon charger considerably simplifies the technology used by high-power (43 kW) charging stations. Since these fast-charging stations will no longer need a built-in rectifier, they will cost just onequarter of their current price and be easier to deploy. This innovation will contribute to the development of electric vehicle use.
