Charging Costs
Cost to Charge BMW iX
Updated March 2026
The BMW iX has a 71 kWh battery and consumes about 197 Wh/km, reflecting its large SUV size and weight. With a 405 km range, it needs more energy per kilometer than smaller EVs, so charging costs are higher per trip. Based on what our users tell us, the iX rewards drivers who prioritize home charging and moderate driving speeds. A full charge gives you a WLTP rated range of approximately 425 km. Here is what it costs to charge at home, at public AC chargers, and at DC fast chargers across Europe. Always check your vehicle's manual for exact specifications.
Charging costs vary significantly depending on your electricity tariff, time of day, charging network, subscription, and location. The numbers below are estimates based on average European electricity prices and may not reflect what you actually pay. Always check your network's app for current pricing before charging.

Charging Costs by Country
These are approximate costs based on average electricity prices. Actual costs depend on your tariff, time of day, and charging network.
| Country | Home (per 100 km) | DC fast (per 100 km) | Full charge (DC) |
|---|---|---|---|
| Germany | €6.40 | €11.45 | €41.89 |
| France | €4.85 | €10.09 | €36.92 |
| Norway | €2.33 | €7.76 | €28.40 |
| Finland | €2.72 | €7.37 | €26.98 |
| United Kingdom | €5.63 | €17.27 | €63.19 |
Prices are approximate gross averages including VAT. Actual costs vary by provider, tariff, and time of use.
How to Calculate BMW iX Charging Costs
Calculating your charging cost comes down to two numbers: how much energy your car uses, and how much you pay for that energy. Here is the formula.
Cost per 100 km = (consumption in Wh/km × 100 ÷ 1000) × price per kWh
Cost per full charge = battery capacity in kWh × price per kWh
Example: BMW iX at home
If your home electricity costs €0.25 per kWh (a rough European average), and the BMW iX consumes approximately 194 Wh per kilometer:
- Energy per 100 km: 194 × 100 ÷ 1000 = 19.4 kWh
- Cost per 100 km: 19.4 × €0.25 = €4.85
- Full charge (0-100%): ~71 kWh × €0.25 = €17.75
Example: BMW iX at a DC fast charger
DC fast chargers typically cost more, often around €0.45 per kWh or higher. Using the same formula:
- Cost per 100 km: 19.4 × €0.45 = €8.73
- Full charge (0-100%): ~71 kWh × €0.45 = €31.95
Keep in mind: These are simplified examples. Your actual cost depends on your specific electricity tariff (which varies by time of day and provider), any charging network subscription you have, session fees, idle fees, and how efficiently you drive. Cold weather, high speeds, and heavy loads all increase consumption. Use these numbers as a starting point, not a guarantee.
Home Charging vs Public Charging
Where you charge makes the biggest difference in what you pay. Here is how the options compare for the BMW iX.
Home charging (AC, typically 3.7 to 22 kW)
The cheapest option. You pay your home electricity rate, which in most European countries is between €0.15 and €0.40 per kWh. The BMW iX can charge at up to 11 kW on AC, so a full charge from empty takes several hours. Most drivers plug in overnight and wake up to a full battery. If your energy provider offers off-peak rates, charging between midnight and 6 AM can reduce costs further.
Public AC charging (typically 7 to 22 kW)
Public AC chargers at shopping centres, workplaces, or on-street locations usually cost more than home electricity but less than DC fast chargers. Prices range from €0.25 to €0.50 per kWh depending on the network and country. Some are free (employer-provided or included in parking).
DC fast charging (up to 148 kW)
The fastest but most expensive option. The BMW iX supports DC fast charging at up to approximately 148 kW, which can take the battery from 10% to 80% in roughly 34 minutes under good conditions. DC prices typically range from €0.35 to €0.70+ per kWh. Some networks also charge per-minute fees or session fees on top.
Should You Charge to 80% or 100%?
You may have heard the advice to "only charge to 80%." Whether this applies to you depends on how you charge and what battery your BMW iX has.
At DC fast chargers
Charging speed slows down significantly above 80% on most electric cars, including the BMW iX. The last 20% can take as long as the first 60%. If you are on a road trip and paying per kWh (or per minute), stopping at 80% saves both time and money. This is a practical recommendation for fast charging, not a strict rule.
At home (AC charging)
At home, charging to 100% occasionally is generally fine. The speed taper above 80% does not matter when you are charging overnight on cheap electricity. Some manufacturers recommend keeping the daily limit around 80-90% to help with long-term battery health. Check your BMW iX's manual for the manufacturer's specific recommendation.
Battery care advice varies by manufacturer, battery chemistry, and model year. The above is general guidance. Always follow the recommendations in your BMW iX's owner manual.

Tips to Reduce Charging Costs
- Home charging is especially important for the iX. At 197 Wh/km, every kilometer costs more energy than a smaller EV, so the difference between home and public charging rates has a bigger impact on your monthly bill.
- Use BMW's scheduled charging to charge during off-peak hours. A full home charge of the iX's 71 kWh battery at off-peak rates costs significantly less than the same charge at a public fast charger.
- The iX supports DC fast charging at up to 148 kW. Its charging curve is relatively flat, which is good, but still stop at 80% to avoid paying for slow top-up speeds.
- Reduce highway speed when possible. The iX's tall, heavy body means consumption rises steeply above 120 km/h. Dropping from 130 to 110 km/h can noticeably reduce your cost per kilometer.
- Use the iX's adaptive regeneration, which adjusts braking strength based on traffic. In stop-and-go driving, this recovers meaningful energy and brings your real-world consumption closer to the rated figure.
Charge at home to 80% for daily driving, which gives you about 325 km of range. The iX's higher consumption means public fast charging costs add up quickly. For road trips, plan charging stops at stations with competitive per-kWh pricing, and arrive with the battery below 20% to make the most of the iX's fast charging capability.
These tips are general suggestions. Your situation may differ depending on your electricity contract, driving patterns, and local charging infrastructure. Always follow safe charging practices and your vehicle manufacturer's guidelines.
