Infineon Technologies has announced a partnership with Sinexcel Electric in Shenzhen for what it calls the ‘Energy Internet’.

Infineon will provide Sinexcel with its 1200 V CoolSiC MOSFET power semiconductors and EiceDRIVER 1200 V single-channel isolated gate drivers to boost the efficiency of energy storage systems in th e’energy internet’ in China.

According to the Chinese Ministry of Industry and Information Technology, in the first half of 2023, the newly installed capacity of energy storage reached 8.63 GWh, equivalent to the total installed capacity of previous years.

The efficiency and power density of energy storage systems are key factors while the size, weight and cost of energy storage systems are closely related to the energy conversion efficiency and directly affect the product cost.

The higher power density of the 1200 V CoolSiC MOSFETs can reduce losses by 50 percent and provide ~2 percent additional energy without increasing the battery size, which is especially beneficial for high-performance, lightweight and compact energy storage solutions.

This allows a system efficiency of up to 98 percent, which is 1 percent higher than that of traditional designs for connected on-grid and off-grid energy storage applications in both domestic and overseas markets, which Sinexel is calling the ‘energy internet’

“The SiC power solution is an important component for future green energy production and storage applications. Infineon’s cooperation with Sinexcel in the field of energy storage inverters enables energy storage systems to achieve advantages such as high efficiency, small size, and light weight, providing a solid guarantee for high-reliability and high-performance energy storage systems,” said Yu Daihui, Senior Vice President of Infineon Technologies and Head of Green Industrial Power Division in Greater China.

“By using Infineon’s SiC devices, Sinexcel’s energy storage products are obviously more compact and flexible, with significantly higher efficiency and lower losses, which reduces the heat dissipation cost of systems, is conducive to the long-term efficient and stable operation of products, and helps end users improve their operational stability and shorten their return on investment cycle,” said Wei Xiaoliang, Deputy General Manager of Sinexcel.

“This greatly improves the system competitiveness of our products and enhances the trust of clients in our energy storage products and the brand awareness of Sinexcel. We hope that in the future, Infineon will further provide high-performance and high-stability components to help enhance the competitiveness of Sinexcel’s products on the client side,” he said.;
