Founded in September 2020, Greater Bay Technology (Guangzhou Greater Bay Technology Co., Ltd, hereinafter referred to as GBT) is the first private-held high-tech private enterprise with mixed-ownership, internally incubated by Guangzhou Automobile Group Co., Ltd (GAC). It is jointly funded by GAC Group, GAC Capital and a partnership firm set by former Advanced Technology Team from GAC R&D Center and relevant third parties. GBT focuses on R&D, production, and services of eXtreme FastCharging (XFC) battery, a new generation of breakthrough energy storage and its system. It commits to becoming a first-class innovative company with customer satisfaction, employee’s trust and social praise and to sustainably creating environmentally-friendly high-tech products, services and values for the better life of people.

GAC’s EV model AION V-Plus powered by GBT’s XFC battery pack set the world record of the “fastest electric vehicle charging technology”. After AION V Plus with GBT’s 15-Min(0~80% charing in 15 minutes) battery had gone on sale in September 2021, GAC’s AION V Plus 70 powered by GBT’s 7-Min(0~80% charing in 7.5 minutes) battery was launched into market in 26 August, 2022.

GBT is also active in building up its capacity in battery cells and battery pack. The first phase of the newly built headquarters and production base in Nansha District, Guangzhou City, was completed and put into operation at the end of October 2023. As the world's first specialized factory for eXtreme Fast Charing power batteries, the total production capacity of this base will be 8GWh/year after its full completion, and it has already been put into operation for 4Gwh at the present time.
