How much does it cost to charge a Kia EV9 in California?

California's 12-month average rate, 32.3¢/kWh, is 79% above the U.S. average of 18.0¢/kWh, so the Kia EV9 costs $5.43 more per 100 miles here than at the national rate.

Rates in California are rising: the latest 12-month average is 3.7% higher than in the 12 months before.

In the last 24 months both the cheapest and the most expensive month fell in spring, so the swing reflects price changes rather than a seasonal pattern: April 2025 at 27.8¢/kWh and April 2026 at 35.3¢/kWh, which moves the Kia EV9's monthly charging cost between $107 and $136. The latest published month, August 2026, came in at 29.8¢/kWh, 8% below the 12-month average.

Of the 5 states covered so far, California is the most expensive place to charge the Kia EV9; in Washington it costs $5.39 per 100 miles.

Among the 10 EVs on OutletBill, the Kia EV9 is the 9th cheapest to charge per mile in California. The cheapest is the Tesla Model 3 at $7.86 per 100 miles; the most expensive is the Rivian R1S at $13.86.

Among the 3 standard SUVs on OutletBill, the Kia EV9 ranks 2nd for charging cost in California, behind the Honda Prologue ($10.52 per 100 miles).

At 38.0 kWh per 100 miles, the 2026 Kia EV9 Standard Range RWD uses more energy than most 2026 EVs: 55% of the 321 versions EPA has tested are more efficient.

EPA rates the 2026 EV9 Standard Range RWD at the same efficiency as the 2025 version, 38.0 kWh per 100 miles, with the same 230-mile range.

Across all 5 trims of the 2026 EV9, cost per 100 miles in California ranges from $12.29 for the Long Range RWD to $13.91 for the GT, a difference of $197 a year at 1,016 miles a month.

EPA estimates 8 hours to charge the EV9 Standard Range RWD from empty on a 240-volt Level 2 home charger, short enough to finish overnight. At 1,016 miles a month (about 33 miles a day), a day's driving takes roughly 1 hour on a Level 2 charger.

Electricity would have to cost more than 60.4¢/kWh, 1.9 times California's rate, before the Kia EV9 cost more per mile than the 2027 Kia Telluride FWD. Put the other way, gas would have to fall below $2.70 a gallon.

Gas costs use EIA's California retail average for regular gasoline ($5.05 a gallon over the same 12 months, 40% above the U.S. average of $3.61) and the 2027 Kia Telluride FWD's EPA rating of 22 mpg combined.
