Huawei Aito M6 EV to Feature CATL 12C Sodium-Ion Battery for Ultra-Fast 5-Minute Charging

Huawei’s Aito brand is gearing up to launch a groundbreaking electric SUV that could drastically shorten charging times and reshape battery expectations. Developed in partnership with Seres, this all-new model—rumored to be the Aito M6—will be the first to feature a CATL sodium-ion battery capable of a 12C charging rate, theoretically enabling a full charge in just 5 minutes.

Although real-world charging will involve some throttling to preserve battery longevity, the Aito M6 EV could still deliver 10–80% top-ups in mere minutes, putting it far ahead of current EV charging norms.

The announcement was made during the unveiling of two CATL production lines at the new Seres Super Factory in Chongqing. While Aito hasn’t revealed full specs yet, the spotlight is firmly on its revolutionary battery tech. The sodium-ion-based Freevoy battery enhances performance in cold climates, making it ideal for global markets. A second, fully electric version of the M6 will use CATL’s high-density Qilin battery pack.

For the uninitiated, a 12C charging rate means the battery can accept a charge up to twelve times its capacity. A 50 kWh battery could theoretically charge at 600 kW, while a 100 kWh pack would require a blazing 1,200 kW charger—numbers that could eliminate range anxiety for good.

Aito’s current SUV lineup includes the M5, M7, M8, and flagship M9. The upcoming M6 (or possibly a next-gen M7) is described as a “large-volume car,” designed for mainstream appeal rather than the premium tier. A teaser image confirms it will be an SUV, and Seres executives claim the vehicle will “define new luxury.”

The Huawei-Seres partnership is a standout in the EV world: Seres handles vehicle manufacturing while Huawei powers the software and hardware stack, including its HarmonyOS and HIMA sales network in China.

With the Aito M6, Huawei and Seres are not just entering the EV fast lane—they’re looking to own it.
