Hyundai and Kia, both under the umbrella of Hyundai Motors, have taken distinct approaches to the adoption of the NACS charging standard in the US. While Hyundai has been more proactive, announcing plans to equip its upcoming models with a native NACS port, Kia has opted for a more cautious strategy, offering free NACS adapters to certain EV6 and EV9 owners but requiring others to pay.

Despite these differences, both brands have ensured their EV owners can access the expansive Tesla Supercharger network, providing a convenient charging solution. This decision aligns with the growing trend of car manufacturers partnering with Tesla to expand the availability of fast charging infrastructure in the US. By adopting NACS, Hyundai, and Kia are demonstrating their commitment to providing their customers with a seamless and convenient charging experience.

However, the differing strategies adopted by Hyundai and Kia also highlight the challenges and complexities associated with transitioning to new charging standards. While Hyundai’s proactive approach may lead to greater customer satisfaction in the long run, Kia’s more cautious approach may be seen as a cost saving measure. Ultimately, time will tell whether these strategies will pay off for both brands.

Kia is poised to offer three types of NACS adapters to its EV owners, enabling compatibility with both Tesla Superchargers and existing CCS and J1772 charging stations. While Kia has yet to announce a delivery date for its NACS-equipped model, the CCS1 to NACS adapter will ensure future NACS-equipped Kia EVs can charge on existing CCS DC chargers. Additionally, the J1772 to NACS adapter will allow NACS-equipped Kia EVs to AC-charge on existing Level 2 chargers.

Kia has promised an over-the-air software update in early 2025 that will enable its EVs to charge directly at Tesla Superchargers. However, the cost of the NACS adapters for those not eligible for a complimentary adapter remains uncertain. For reference, GM currently sells the Tesla-made NACS to CCS1 adapter for $225. Third-party adapters may be available at a lower cost.

The charging speed of Kia EVs at Tesla Superchargers may be limited due to Tesla’s lack of 800-volt chargers. Previous experiences with Hyundai, Kia, and Genesis EVs using adapters at Tesla Superchargers have revealed slower charging speeds due to the use of a DC/DC converter. This converter, which is necessary to convert the high voltage from the charger to the lower voltage required by the EV’s battery, can limit the charging rate.

Additionally, the charging infrastructure itself, such as the power capacity of the Supercharger station, can also affect charging speed. It is important to note that the charging experience may vary depending on factors such as the specific EV model, the condition of the battery, and the load on the charging station.

As Kia continues to expand its EV lineup and Tesla continues to invest in its charging infrastructure, it is expected that the charging experience for Kia EV owners will improve over time.
