The Kia EV9 is an all-electric SUV designed for families and long-distance travel, offering multiple trim levels with different battery capacities and charging speeds.
With ultra-fast 350 kW DC fast-charging capability, it is one of the fastest-charging EVs available. This guide covers its charging ports, speeds, costs, and Tesla Supercharger compatibility.
Charging Ports & Power Capabilities
The Kia EV9 is equipped with J1772 (AC charging) and CCS1 (DC fast charging) ports, making it compatible with most public charging networks in North America.
Each trim level supports different charging power levels, as detailed in the table below:
All EV9 trims support a maximum AC charging power of 10.9kW, meaning that the fastest home charging option would be a 48A Level 2 charger. On DC fast chargers, all trims can charge at up to 350kW, enabling significantly faster charging sessions.
Charging Speeds for the Kia EV9
Charging speed depends on the charging level (L1, L2, or DC) and the trim level of the EV9. Below is a breakdown of estimated charging speeds for each charging method.
Level 1 Charging (120V)
Level 1 charging (NEMA 5-15, 120V) is the slowest charging option available for the Kia EV9, but it can still be useful for overnight charging or as a backup solution. Based on the data, here’s a breakdown of charging speeds and estimated charging times:
Charging Speed
- On Level 1 charging, the Kia EV9 charges at approximately 6.7 to 7.4 miles per hour, depending on the trim.
- Charging from 20% to 80% takes around 26 to 34 hours, making it impractical for regular use if fast charging is needed.
- A full charge (0% to 100%) on Level 1 takes between 43 to 57 hours, depending on the trim level.
Miles per Charging Time:
- Adding 30 miles of range takes approximately 4.1 to 4.5 hours.
- Charging 100 miles takes between 13.5 to 15 hours.
Level 2 Charging (240V)
LLevel 2 charging is the most practical and efficient home charging solution for the Kia EV9. Since all trims support 10.9 kW AC charging, using a 48A Level 2 charger allows for the fastest possible home charging performance.
Charging Speed:
- The Kia EV9 charges at approximately 43.8 to 48.4 miles per hour with a 48A charger.
- Charging from 20% to 80% takes around 4 to 5.2 hours.
- A full charge from 0% to 100% takes approximately 6.6 to 8.7 hours.
Miles per Charging Time:
- Charging 30 miles takes around 36-42 minutes.
- Charging 100 miles takes approximately 2.1 to 2.3 hours.
DC Fast Charging (CCS1)
DC fast charging is the fastest way to charge the Kia EV9, making it an excellent choice for road trips and quick top-ups. The Kia EV9 supports 350 kW DC fast charging, which enables rapid charging under optimal conditions.
Charging Speed:
- At 50 kW stations, the EV9 charges at 3.2 to 3.5 miles per minute.
- At 350 kW stations, the charging speed increases significantly to 22.2 to 24.5 miles per minute.
- At 50 kW, charging takes 54.8 to 71.9 minutes, making it relatively slow for a DC charger.
- At 350 kW, this time drops dramatically to 7.8 to 10.3 minutes.
Miles per Charging Time:
- Charging 30 miles at 50 kW takes 8.6 to 9.5 minutes, while at 350 kW, it takes only 1.2 to 1.4 minutes.
- Charging 100 miles at 50 kW takes 28.6 to 31.6 minutes, while at 350 kW, it takes only 4.1 to 4.5 minutes.
Kia EV9 Charging Costs
The cost to charge a Kia EV9 varies based on electricity rates and charging method.
Can Kia EV9 Use Tesla Superchargers?
Charging the Kia EV9 at Tesla Superchargers is possible under certain conditions, and the options will expand soon:
- Using Magic Dock Superchargers: Some Tesla Supercharger stations are equipped with Magic Dock, a built-in CCS1 adapter that allows non-Tesla EVs to charge without needing an external adapter. Kia EV9 owners can currently use these Magic Dock Superchargers without any additional equipment. To find a Magic Dock-enabled location, check the Tesla app or a third-party charging locator.
- Upcoming Support for NACS to CCS1 Adapter: Tesla is in the process of opening its Supercharger network to Kia. As confirmed on Tesla’s official site, Kia will soon gain access to NACS Superchargers using an automaker-provided NACS to CCS1 adapter. This means that once Kia officially joins the network (expected in 2025), EV9 owners will be able to charge at all compatible Tesla Superchargers with the appropriate adapter.
In summary, Kia EV9 can currently charge at Tesla Magic Dock Superchargers, and full compatibility with Tesla’s Supercharger network is coming soon with the introduction of NACS to CCS1 adapters. Stay updated with Kia and Tesla’s announcements for the latest availability.
Conclusion
The Kia EV9 is a well-equipped electric SUV with multiple charging options, ranging from slow Level 1 home charging to high-speed 350kW DC fast charging. For daily use, a Level 2 home charger (40A or 48A) is recommended, while road trips benefit from 350kW DC fast charging.
Although the EV9 cannot currently use most Tesla Superchargers, Kia plans to introduce NACS compatibility by 2025, enabling access with an adapter.
For the best home charging experience, consider using a Level 2 charger or a Tesla to CCS adapter for future Supercharger compatibility.
