EHang Holdings Limited announced that it has established a strategic partnership with Guangzhou Greater Bay Technology Co. Ltd. at the 16th Chongqing International Battery Technology Exchange Conference/Exhibition for the research and development of the world's first Ultra-Fast Charging ("UFC")/eXtreme Fast Charging ("XFC") battery solutions for EHang's electric vertical takeoff and landing ("eVTOL") aircraft. The partnership is to promote the research and development as well as industrialization of eVTOL power system components and modules in the UAM sector, laying an ecological foundation for commercial operations of the low-altitude economy.

Based on EHang's eVTOL aircraft (including EH216-S, VT30 and others), EHang and GBT will jointly develop eVTOL power cells, batteries, packs, charging piles and energy storage systems that meet the airworthiness standards of the Civil Aviation Administration of China (the "CAAC") as well as the 4H standards (i.e. high energy density, high cycle life, high instantaneous charge-discharge rate, and high safety), thereby achieving the adoption and adoption of ultra-fast charging power batteries in EHang's eVTol aircraft. Furthermore, both parties will gradually develop fast-charging piles, stations and other infrastructures to establish the ecology for future commercial operations. Power battery system is one of the core components of aircraft and its performance determines the range, stability, safety, and operational efficiency of the aircraft.

The UFC/XFC batteries to be jointly developed by both parties for eVTOL aircraft will offer a full scale of advantages in terms of (i) fast charging speed, which is expected to only take five to ten minutes to be charged from 30% to 80%, (ii) over 200Wh/kg high energy density of the battery system, and (iii) long cycle life of over 2,000 cycle times. It will further enhance EHang's eVTAL products in terms of safety, endurance, and operational efficiency, in order to better meet the core demands of convenience, efficiency, and economy for large-scale and high-frequency operations of eVTOL aircraft in urban low-altitude mobility.
