Infineon signs memorandum of understanding with China’s Lingji
Infineon Technologies AG Munich, Germany and electrical component maker Lingji Innovation Technology Co Ltd (a subsidiary of Beijing-based Ninebot Ltd) have signed a memorandum of understanding (MoU) to further drive gallium nitride (GaN) technology in the area of light electric vehicles (LEV). Infineon provides GaN products supporting Lingji to develop high-performance electric two-wheeler inverter systems based on its new-generation CoolGaN G5 power transistors to drive advances in energy efficiency and performance.

Specializing in smart control technologies, Lingji will leverage the high-switching frequency and high-efficiency performance of Infineon’s CoolGaN G5 power semiconductors, combined with its self-developed intelligent algorithms, to target improved drivetrain efficiency, breakthrough power density levels, and compliance with official requirements for range and size. Considering China’s new standard (that e-Scooter’s plastic mass shall not exceed 5.5% of vehicle mass) GaN became a preferred choice as it can reduce the number of passive components for space optimization. The MoU aims to design GaN motor drive technologies to optimize solutions for 48V–72V wide-voltage adaptation and inverter control, providing compact, highly compatible core components for high-end models and shared mobility scenarios.
“With our cutting-edge GaN solutions, we enable customers to achieve more compact designs, reduced system weight, and higher efficiency in LEV inverters,” says Peter Schaefer, executive VP & chief sales officer Automotive at Infineon. “In addition, we deliver a comprehensive system solution that helps our customers accelerate time-to-market while minimizing design-in efforts,” he adds.
For consumers, LEVs is an affordable and accessible entry point into electric mobility. Unlike cars, LEVs typically do not rely on extensive charging infrastructure, as removable batteries allow users to charge at home using standard electrical sockets. Industry analysts estimate that this market will reach $340bn by 2030.
