Quick answer
The Renault Megane E-Tech charges from 10% to 80% in about 33 minutes on a DC fast charger (129 kW peak). A full charge at home on a 7 kW wallbox takes approximately 9 h 31 min.
Charging Times at Every Speed
These times are estimates based on the Renault Megane E-Tech's 60 kWh useable battery. Real charging times vary with temperature, battery condition, and state of charge.
| Charger | Power | 0 to 100% | 10 to 80% | Range/hour |
|---|---|---|---|---|
| Home 7 kW | 7 kW AC | 9 h 31 min | - | 40 km/h |
| Public AC 11 kW | 11 kW AC | 6 h 4 min | - | 63 km/h |
| Public AC 22 kW | 22 kW AC | 3 h 2 min | - | 125 km/h |
| DC Fast | up to 129 kW | ~1 h 13 min | 33 min | - |

What Affects Charging Time?
The charging curve matters more than peak power. The Renault Megane E-Tech can accept up to 129 kW from a DC fast charger, but it only reaches that speed at lower states of charge. As the battery fills past 60-70%, the charging speed tapers off to protect battery health. That is why charging from 10% to 80% is much faster per percentage point than charging from 80% to 100%.
Temperature has a big effect. In cold weather, the battery's internal resistance increases and the car limits charging power to prevent damage. The Renault Megane E-Tech supports battery preconditioning, which warms the battery before you arrive at a fast charger. This can significantly reduce charging time in winter.
Battery chemistry plays a role. The Renault Megane E-Tech uses NMC cells, which typically offer fast peak charging speeds but benefit from keeping daily charge levels below 80%.
Tips for Faster Charging
- Precondition the battery before arriving at a DC fast charger. Set your navigation to the charger and the car will warm the battery automatically.
- Charge between 20% and 80% for the fastest DC speeds. The last 20% can take as long as the first 60%.
- Avoid charging above 80% on road trips. The time spent waiting for 80-100% is rarely worth the extra range.
- Cold weather slows charging. In winter, expect 10-30% longer charging times depending on conditions.
- For daily driving, charge to 80% to help preserve long-term battery health.
