GAC Group's Inpai battery produced its 300,000th pack today. Feng Yu, vice
president of GAC's Haobo Aion BU, said many carmakers' in-house battery efforts
focus on pack integration and BMS application layers while core cell technology
remains externally sourced; GAC pursues full-stack in-house development and
production from materials and cells to pack. He said owning core battery
technology and product-definition rights are necessary for healthier development.
