Infineon signs GaN MoU with Lingji
Infineon and Lingji Innovation Technology, a subsidiary of Ninebot, have signed a Memorandum of Understanding (MoU) to further drive GaN technology for light electric vehicles (LEV) such as e-scooters.
The MoU aims to design GaN motor drive technologies to optimise solutions for 48V-72V wide-voltage adaptation and inverter control
Infineon already provides CoolGaN G5 products to Lingji for e-scooter inverter systems. Lingji will use the high-switching frequency and efficiency of CoolGaN G5 semiconductors with proprietary algorithms, to target improved drivetrain efficiency, power density levels, and compliance with the latest Chinese requirements for e-scooter range and size.
The latest Chinese standard says that e-scooter’s plastic mass must not exceed 5.5 percent of vehicle mass, which makes GaN a preferred choice as it can reduce the number of passive components for space optimisation.
“With our cutting-edge GaN solutions, we enable customers to achieve more compact designs, reduced system weight, and higher efficiency in LEV inverters,” said Peter Schaefer, executive VP and chief sales officer for automotive at Infineon.
"We are excited to work with Infineon to bring the next generation of electric two-wheeler inverters to market, offering our customers unparalleled performance, efficiency, and reliability,” said Xu Chao, general manager of Lingji. “By leveraging Infineon's cutting-edge GaN G5 power devices and our own intelligent algorithms, we will deliver LEV inverters that provide a smoother and more convenient ride for our customers while allowing for reduced energy consumption and lower emissions.”
Unlike cars, LEVs require no charging infrastructure (removable batteries allow users to charge at home using standard electrical sockets). Industry analysts Mckinsey estimate that this market will reach $340 billion by 2030.
