Focused on Power Energy Storage | Shaanxi Hechunk Era Technology Co., Ltd Establishes EDLC Technical Barriers Through Full-Stack In-House R&D

Against the backdrop of advancing new power system development, demand for short-time high-power and high-frequency charge-discharge energy storage equipment is rapidly rising in scenarios including grid frequency regulation, AI computing centers, rail transit and industrial equipment. As the core carrier of power-type energy storage, electric double-layer capacitors (EDLCs) are gaining growing industrial value. Breakthroughs in device performance rely on forward design of single cells and independent controllability of core manufacturing processes. Rooted in full-chain R&D of supercapacitors, Shaanxi Hechunk Era Technology Co., Ltd has formed a complete technical loop covering cell development, capacitor management system (CMS), thermal management and integrated container systems, delivering customized solutions for power-type energy storage projects across multiple industries.

The core distinction between power-type energy storage and conventional energy-type energy storage lies in millisecond-scale power throughput and cycle endurance up to millions of cycles. Lithium batteries, a typical energy-type storage device, generally only achieve several thousand cycles. When subjected to frequent charge-discharge cycles of dozens to hundreds of times per day in scenarios such as grid frequency regulation and braking energy recovery, they suffer obvious capacity degradation within a few years and require full pack replacement, driving up the full-lifecycle operation and maintenance cost of projects. By contrast, supercapacitors adopt a distinctive energy storage mechanism to support millions of charge-discharge cycles. Capable of enduring deep pulse charge and discharge over long periods, they drastically cut spare parts and downtime maintenance costs, making them an irreplaceable technical solution for power-oriented applications.

In terms of technical route, EDLC electric double-layer supercapacitors store energy through physical adsorption and desorption of ions on electrode surfaces without complex electrochemical reactions, delivering highly reversible energy storage processes. With a rated single-cell voltage of 3.0 V, they feature outstanding merits including ultra-long service life of millions of cycles, millisecond instantaneous pulse output, stable operation across a wide temperature range of -40℃to +65℃, and maintenance-free performance. They are well suited for high-impact and high-frequency operating conditions such as primary/secondary grid frequency regulation, rail transit braking energy recovery, industrial voltage sag mitigation and port hoisting equipment.

The performance ceiling of devices is determined by underlying materials and manufacturing processes. Drawing on accumulated foundational craftsmanship, Shaanxi Hechunk Era Technology Co., Ltd has built full-spectrum capabilities covering cells, self-developed CMS, intelligent liquid cooling thermal management and integrated container energy storage systems. Its self-developed EDLC products have been deployed in major grid projects such as megawatt-level thermal-power storage coordinated regulation and SPG static full-power compensation, fully verifying the engineering value of million-cycle performance under high-frequency impact working conditions. For complex operating conditions of large EPC projects, Shaanxi Hechunk Era Technology Co., Ltd can also conduct operating condition simulation and calculation, and deliver customized EDLC+LIC hybrid energy storage schemes to precisely match working conditions of different branches.

Domestically, EDLC products are accelerating their penetration into grid, computing, rail transit and overseas energy storage supply chains, with the domestic substitution process continuously speeding up. Industry experts note that the million-cycle capability of supercapacitors is not a marketing figure, but an engineering benchmark for power energy storage scenarios. Leveraging the characteristics of long cycle life and high power is critical for energy storage system design and project selection. Going forward, Shaanxi Hechunk Era Technology Co., Ltd will continuously iterate material formulations, manufacturing processes and system integration technologies, promoting large-scale deployment of domestically manufactured high-performance supercapacitor equipment in new power systems, computing infrastructure and rail transit sectors, and facilitating high-quality development of the power-type energy storage industry.
