Empowering the Future with
High-Energy Super Capacitor Technology
From 48V modular units to MW-grid-scale containerized systems. We provide sustainable, ultra-long-cycle energy storage solutions for data centers, oil & gas, and modern power grids.
The Core AHSC Technology
Redefining the Standard of Energy Storage
Asymmetric Hybrid Supercapacitor technology represents the next generation of hybrid energy storage, engineered to resolve the long-standing performance trade-offs between traditional supercapacitors and batteries.
By synergistically integrating a high-energy pseudocapacitive positive electrode with a high-power capacitive negative electrode, AHSC achieves a unique and compelling balance of capabilities.
For C&I and 800Vdc Data Center applications, we offer a high-voltage platform based on the 75S5P standard architecture. This platform allows for precise voltage customization within a unified architecture to perfectly match various PCS voltage ranges, enabling seamless integration and effortless scaling for system integrators.
