April 3, 2025, Lake Forest, CA – SemiQ Inc, a designer, developer, and global supplier of superior silicon carbide (SiC) solutions for ultra-efficient, high-performance, and high-voltage applications, has confirmed it has begun shipping its SiC MOSFET modules for integration into advanced cell cycling systems used by several of the world’s leading battery manufacturers.
In lithium-ion batteries, cell cyclers enable the formation of a stable solid electrolyte interphase to enable increased longevity and performance. The systems also enable battery manufacturers to perform battery degradation analysis, temperature and stress testing, and check for defects or performance issues.
To undertake these tasks, the cyclers need to accurately charge and discharge batteries, with high switching frequencies enabling more precise control of current and voltage to avoid damage from overcharging/discharging. For this function, the MOSFETs need to withstand the thermal stress of repeated power cycling, with failure leading to test disruption and inaccurate data. Conversion efficiency is also vital in minimizing operational costs.
SemiQ is supplying its GCMX003A120S3B1-N and the GCMX003A120S7B1 QSiC™ 1200 V SiC half-bridge modules for use in 100 Kw cyclers (10 x 10 Kw cells with parallel connections).
These high-speed switching MOSFET modules are highly efficient with exceptionally low switching losses, are designed with a reliable body diode, have been tested to over 1350 V and implement a rugged design with easy mounting. Each 10 kW cell will integrate 12 modules, with 120 per 100 kW per cycler.
Dr. Timothy Han, President at SemiQ said: “Reports1 show that the electrification of transportation is among the most important steps that can be taken to reach net-zero. For this, the evaluation of battery performance, durability, and efficiency plays a vital role in enabling the development of longer-range, longer-life EV batteries. We’re delighted to be working with one of the world’s leading cell cyclers and this partnership is testament to the ruggedness and efficiency of our SiC technology.”

Notes to editors
1 An October 2024 report by the IMF said “The move toward EVs … is seen as a key way to help countries achieve climate goals.” And cited that transportation accounts for “36% of greenhouse gas emissions in the U.S., 21% in the European Union, and 8% in China.” (source IMF via Reuters, 2024)
Similar analyses have also been undertaken by the US Environmental Protection Agency (EPA) has stated that transportation is the country’s largest contributor greenhouse gas emissions, making 28% of the total emissions from the US. (source EPA 2022), with the Center For Climate And Energy Solutions (C2ES) stating road vehicles are responsible for 83.5% of these emissions (source C2ES, 2023).
