EHang, Greater Bay Technology Collaborate “to Develop World’s First Ultra-Fast Charging Batteries for eVTOL Aircraft”

EHang announced over the week­end (April 28th) at the 16th Chongqing Inter­na­tion­al Bat­tery Tech­nol­o­gy Exchange Conference/Exhibition, it has formed a col­lab­o­ra­tion with Greater Bay Tech­nol­o­gy (GBT), a cut­ting edge bat­tery com­pa­ny, to cre­ate the world’s first ultra-fast charg­ing (UFC) bat­tery for EHang’s AAV air­craft, reports a press release. 

The part­ner­ship is to pro­mote the R&D as well as indus­tri­al­i­sa­tion of eVTOL pow­er sys­tem com­po­nents and mod­ules in the Urban Air Mobil­i­ty (UAM) sec­tor, form­ing an eco­log­i­cal foun­da­tion for com­mer­cial oper­a­tions of the low-alti­tude econ­o­my.

EHang and GBT are “to 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 (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 adap­tion and adop­tion of ultra-fast charg­ing pow­er bat­ter­ies in EHang’s eVTOL air­craft,” explains the release. “Fur­ther­more, both par­ties will grad­u­al­ly devel­op fast-charg­ing piles, sta­tions and oth­er infra­struc­tures to estab­lish the ecol­o­gy for future com­mer­cial oper­a­tions.”

Huazhi Hu, Founder, Chair­man and CEO of EHang, remarked, “Our coop­er­a­tion will pro­mote the estab­lish­ment of UFC ecol­o­gy for eVTOL air­craft, reduce the charg­ing time of eVTOL, and strength­en the foun­da­tion for low-cost, large-scale and high-effi­cien­cy com­mer­cial oper­a­tions in the low-alti­tude econ­o­my.”

Pei Feng, Pres­i­dent of GBT, added, “We are cur­rent­ly the only com­pa­ny in the world that has achieved mass pro­duc­tion of con­stant-pow­er high-rate pow­er bat­ter­ies. The coop­er­a­tion will explore an effi­cient oper­a­tion mode for low-alti­tude trans­porta­tion and pro­pel fur­ther devel­op­ment and progress in the UAM indus­try.”

The release con­tin­ues, “The 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 bat­ter­ies to be joint­ly devel­oped by both par­ties for eVTOL air­craft will offer many advan­tages.”

These include: -

: Fast charg­ing speed, expect­ed to only take five to ten min­utes from 30 per­cent com­plete to 80 per­cent.

: Over 200Wh/kg high ener­gy den­si­ty of the bat­tery sys­tem.

: A long cycle life of over 2,000 cycle times. 

This will fur­ther enhance EHang’s eVTOL prod­ucts in terms of safe­ty, endurance and oper­a­tional effi­cien­cy, in order to improve the core demands of con­ve­nience, effi­cien­cy and econ­o­my for large-scale and high-fre­quen­cy oper­a­tions of eVTOL air­craft in an urban low-alti­tude mobil­i­ty.

Back­ground

Found­ed in 2020, Greater Bay Tech­nol­o­gy is the first pri­vate-held, high-tech pri­vate enter­prise with mixed-own­er­ship, inter­nal­ly incu­bat­ed by Guangzhou Auto­mo­bile Group.

GBT focus­es on R&D, pro­duc­tion and ser­vices of eXtreme Fast Charg­ing bat­ter­ies, viewed as a new gen­er­a­tion of break­through ener­gy stor­age sys­tems.

The com­pa­ny cur­rent­ly estab­lish­es three major prod­uct series includ­ing ultra-fast, super-fast, and stan­dard-fast. GAC’s AION V Plus 70 pow­ered by GBT’s 7‑Min(0~80 per­cent charg­ing in 7.5 min­utes) bat­tery set the world record of the “fastest elec­tric vehi­cle charg­ing tech­nol­o­gy” by the World Record Cer­ti­fi­ca­tion Body.
