The Zoe Charger

The Zoe’s charging system is called the Chameleon charger. It uses the motor windings as part of the charging system, and an inherent features of this design is that it can charge off three phase AC. Three phase is common in many parts of the world, including Europe and NZ (but not in the USA). One of the advantages of this configuration is that it is possible to charge at up to 43 kW, while not requiring an off-board charging unit. (By contrast, DC fast charging systems supply DC to the car and the AC-DC rectifier is located in the fast charging station, which makes a DC charging stations significantly more expensive). A disadvantage of this system is that charging below 3 kW is very inefficient.

The following table shows the charging times at various charging rates. Note that the R240/R90 was designed to be more efficient than the Q210/Q90 at low charging currents, although the ability to charge at 43 kW was dropped. (The higher charging rates of 22 kW and 43 kW are possible when charging at three phase at currents of 32 amps and 63 amps respectively.)

Charging Power Charging times
22 kWh Battery 41 kWh Battery
Q210 R240/R90 Q90 R90
2.3 kW (0-100%) 17-18 hours 13 h 30 min 30 h 30 min 25 hours
3.7 kW (0-100%) 9 hours 8-9 hours
7.4 kW (0-100%) 4 hours 3-4 hours 8 h 30 min 7 h 30 min
22 kW (0-100%) 1 h 45 min 2 h 40 min 2 h 40 min
43 kW (0-100%) 1 h 45 min 1 h 30 min 2 h 40 min
22 kW (0-80%) 60 minutes 60 minutes 1 h 40 min 1 h 40 min
43 kW (0-80%) 30 minutes 60 minutes 65 minutes 1 h 40 min

Note: The above charging times are from Zoe brochures and the charging time calculator at: https://www.renault.co.uk/vehicles/new-vehicles/zoe-250/battery-and-charging.html#simulateur-recharge. Note that there was not always complete agreement between the different sources.


The following table indicates where such powers are found.

Single 16 amps 3.7 kW Caravan socket (‘blue commando’)
Single 32 amps 7.4 kW Type 2 electric car charging station (socket) wired to a single phase; industrial single phase socket
Triple 32 amps 22 kW Type 2 electric car charging station (socket); industrial three phase socket
Triple 63 amps 43 kW Type 2 electric car charging station (tethered)
