Chinese automakers race in fast-charging tech

Chinese automakers are increasing their focus on fast-charging technology, with Chery recently entering the field by promising a vehicle range of 500 km in just 5 minutes of charging. Other major Chinese manufacturers, such as BYD, Geely, CATL, and Hongqi, are also offering fast-charging capabilities that take less than 10 minutes.

Chery's charging claims and limitations

Chery’s proposed charging system has a power output of 1.44 MW, which is lower than Geely’s 1.5 MW or 2.2 MW. However, Chery claims its overall charging speed is more favorable. It advertises a 6-minute and 50-second charge time for a 10/97% charge, compared to BYD’s 9 minutes. Chery also states it can restore 500 km of range in 5 minutes, though this likely refers to charging from 10% to 80% in the Chinese testing cycle.

BYD’s advantage in technology deployment

BYD holds a significant edge in deploying its Flash Charge technology across its entire product line. This includes a wide range of models in China, from high-end Denza vehicles to the new Seagull city car. The company has also installed over 12,000 charging stations in China since April, though it is behind its goal of reaching 20,000 stations by the end of the year.

Chery’s charging infrastructure and future plans

Chery has developed a charging station with an efficiency of 96.5%, with 100 already in operation. The company plans to expand to 20,000 stations by 2029, all compatible with vehicle-to-grid (V2G) technology. Chery also promises a robotic arm for fully autonomous charging, which will be enhanced when vehicles reach level 3 autonomous driving certification.

Uncertainty around Chery’s vehicle availability

Chery has not confirmed when its Volt-Dragon fast-charging technology will be available on existing or future models. A demonstration vehicle was an iCar V23 SUV, suggesting the technology may be introduced on compact vehicles, possibly for the European market. However, Chery has been cautious about providing a clear timeline or details.
