Renault says:
"ZOE is the only electric vehicle to feature the Chameleon charger. Patented by Renault, this charger is compatible with all power levels up to 43kW. Charging batteries at a charging station can take between 30 minutes and nine hours. For example, ZOE can be charged in an hour at 22kW. This intermediate power level extends battery life and puts less pressure on the power grid than the fast-charging of batteries at 43kW. Fast-charging stations are currently equipped with high-power chargers. Now that the Chameleon charger is fitted to the vehicle, there is no longer any need for chargers at charging stations. New fast-charging stations will be opened which are easier and more cost-effective. They will cost less than €3,000, a quarter of the cost of existing fast-charging stations."

Looks pretty clear to me.
