Cost to charge a BMW iX3
A full charge from empty draws about 127.3 kWh from the wall. At 18 cents per kWh it costs about $22.91, and a 20% to 80% top-up about $13.75. The EPA rates the iX3 50 xDrive (21 inch Summer Tires) at 32 kWh per 100 miles, which works out to 5.8 cents a mile. The US average home rate was 18.16 cents per kWh in August 2026 (EIA); the EV charging cost calculator takes your own rate.
BMW iX3 fast charging
DC fast charging bypasses the car's onboard charger and is far quicker, but the speed depends on each model's charging curve, which slows as the battery fills. That's why fast-charge times are quoted from 10% to 80%. The EPA doesn't test DC charging, so check BMW's quoted figure for the iX3. The EV charging curve guide explains why it slows.
