NIO ET9 Charging Cost in China
By mht-dev, Frontend Engineer & Creator
Estimate the cost and time to charge a NIO ET9 (full battery electric vehicle / BEV) in China, calculated from its battery capacity and local electricity rates, both at public DC fast charging and at home.

A real-world estimate discounted from the manufacturer's claimed figure; actual distance depends on driving style, speed, and conditions.
Estimated from the realistic range, not a measured consumption figure; actual use varies with driving and conditions.
NIO ET9 charging cost & time
| Scenario | Energy | Time | Cost |
|---|---|---|---|
| Public DC 20% → 80% | 60 kWh | 7 minutes | ¥108.00 |
| Public DC 0% → 100% | 100 kWh | 18 minutes | ¥180.00 |
| At home (AC) 20% → 80% | 60 kWh | 5 hours 27 minutes | ¥36.00 |
NIO ET9 charging time by charger power
How long the NIO ET9 takes to charge at different charger power levels, capped by its own onboard limits.
| Charger | Power | Charge | Time |
|---|---|---|---|
| Standard outlet | 2.2 kW | 0% → 100% | 45 hours 27 minutes |
| Home wallbox | 7 kW | 0% → 100% | 14 hours 17 minutes |
| Public AC | 11 kW | 0% → 100% | 9 hours 5 minutes |
| DC fast | 600 kW | 10% → 80% | 8 minutes |
AC rows assume constant charging power and a 0% to 100% charge. Real times vary with the onboard charger, temperature, and the charger you use.
The DC fast row (10% to 80%) models the charging curve tapering as the battery fills, so it is more realistic than a flat estimate. Real DC times still vary with temperature, battery state, and the charger.
Charging speed
The NIO ET9 is estimated to charge from 20% to 80% on public DC fast charging in about 7 minutes (ultra-fast DC).
Estimated. Real DC charging slows as the battery fills, so the time varies by model, temperature, and charger.

Battery care
This car uses an NMC battery. For daily use, charging to about 80% and topping up to 100% only before long trips helps it last longer; heat is the main thing that ages it.
Savings vs a petrol car
This charge adds about 298 km of range for ¥108.00. Driving the same distance on petrol would cost:
| Engine size | Petrol cost | You save |
|---|---|---|
| ≤ 1000 cc | ¥144.86 | ¥36.86 |
| 1000–1500 cc | ¥171.19 | ¥63.19 |
| 1500–2000 cc | ¥210.70 | ¥102.70 |
| 2000–2500 cc | ¥250.21 | ¥142.21 |
| > 2500 cc | ¥302.88 | ¥194.88 |
Estimated from typical combined fuel use by engine size and Gasoline 92# at ¥8.85/L. Charging at home saves the most; actual figures vary with driving and conditions.
